The Colonial Pipeline and JBS attacks, among others, showed us our national resilience is only as strong as public-private sector collaboration.

As our nation's most critical infrastructure faces relentless threats in cyberspace, cybersecurity remains top-of-mind for the federal government. The Colonial Pipeline and JBS attacks, among others, showed us that our national resilience is only as strong as public-private sector collaboration. And as ransomware attacks remain the norm, new collaborative strategies and programs are underway to build and foster cyber resilience.

**Notable Steps in the Right Direction  
**

The State Department's Bureau of Cyberspace and Digital Policy (CDP) serves as a catalyst for building cyber stability, future incident reporting, and cyber-governance regulation. Its mission is to encourage responsible nation-state behavior in cyberspace, advance policies that protect the integrity and security of the Internet, serve US interests, promote competitiveness, and uphold democratic values.

We've also seen progress with the Cybersecurity and Infrastructure Security Agency's (CISA) new Shields Up program, which outlines guidance for public and private organizations to reduce the likelihood of a successful cyber intrusion. CISA's Jen Easterly emphasizes the program is all about "preparation, not panic."

The National Institute of Standards and Technology (NIST) also recently published guidance for securing enterprises against supply chain attacks targeting critical infrastructure. The new guidance stresses the importance of risk monitoring in cyber defense.

**Collaboration Across Sectors  
**

In addition to the above federal mandates and programs, public-private partnerships play a vital role in strengthening cyber intelligence, defense, and protection capabilities. As the world around us grows increasingly interconnected, cyber concerns that threaten to shut down or disrupt private entities also threaten the well-being of the federal government and government operations — and vice versa.

Because of attacks like Colonial Pipeline, President Biden signed the Cyber Incident Reporting for Critical Infrastructure Act of 2022 into law — which laid out new "mandatory reporting requirements for critical infrastructure entities in the event of certain cyber incidents and ransomware payments."

The commitment to public-private partnerships continues to show up at all levels of government and private sector operations. Another proof point: CISA established the Joint Cyber Defense Collaborative (JCDC) in August 2021 to unify defensive actions and mitigate risk in advance of cyber incidents. The goal of this program is to strengthen the nation's cyber defenses through innovative collaboration, advanced preparation, and information sharing and fusion.

Programs and mandates like these are critical steps in bolstering national cyber resiliency. But to achieve herd resilience, we need to work together to shore up our shared cyber defenses, and for many, that starts with adhering to basic cybersecurity protocol.

**Building Cyber Resilience  
**

A pivotal factor in building cyber resilience and proactively preparing for the next attack starts with ensuring your organization maintains good cyber hygiene. In a nutshell, cyber hygiene is the practice of fundamental security behaviors, amplified through the adoption of supporting processes and technical controls. It's nothing revolutionary — back up your data, patch when you're told to patch, segment your networks, micro-segment your applications and workloads, etc.

One proactive security framework that has gained popularity and more widespread adoption over the last several years is zero trust. The Biden Administration's Cyber EO, which recently hit its one-year anniversary, emphasized the immediate need for federal agencies to implement zero trust to bolster national cyber resilience.

A key component of achieving zero trust security is zero-trust segmentation (i.e., microsegmentation). It's designed to stop lateral movement and reduce the attack surface by breaking down the internal infrastructure (think the data center, cloud environment, network, etc.) into smaller segments. In simple terms, think of microsegmentation like a hotel. Just because you're able to get into the hotel (bypassing firewall defenses) doesn't mean you're able to automatically access your room. Because every room has a key, you can only access yours once you're checked in and your access is granted.

Microsegmentation is the critical component of the workload and application pillar of zero trust reference architecture and your zero-trust security strategy; it's designed to stop the spread of cyberattacks and, malware, by isolating workloads and devices across the entire hybrid attack surface. Successfully implementing zero trust takes effort but ensuring your security team has an action plan in place and is taking small steps forward will ultimately better position you and your software supply chain to combat and withstand evolving threats.

**Our Best Defense Against Cyber Threats  
**

When taking steps to improve cyber defenses, agencies and critical infrastructure organizations often first look to legacy solutions: upgrading their networks, focusing on user access, bolstering perimeter defenses, or making sure all devices that connect to the network are approved devices.

While those steps are important, they're only one piece of the puzzle, and they will not stop the lateral movement of cyberattacks. Just think back to SolarWinds, which went undetected in federal systems for more than 14 months. A proactive cyber strategy, coupled with increased public-private partnerships and adherence to strong cyber hygiene practices, are critical components of bolstering our national cybersecurity posture.

Zero Trust Bolsters Our National Defense Against Rising Cyber Threats

Latest campaigns are a break from its usual financially motivated attacks and appear aligned with Russian interests, security researchers say.

In a break from precedent, Russia's hitherto purely financially motivated Trickbot threat group has systematically been attacking targets in Ukraine over the past three months, apparently in support of Russian government interests in the region.

Researchers from IBM's X-Force threat intelligence group this week said they had uncovered two campaigns — and analyzed four others that Ukraine’s Computer Emergency Response Team (CERT-UA) disclosed — where Trickbot went after targets in Ukraine. The campaigns began after Russia’s invasion of Ukraine in February and have targeted Ukrainian state authorities, government organizations, specific individuals, and the general population. Several of the attacks have involved phishing emails with various themes designed to grab the attention of Ukrainian users — included some that are war-related.

The attacks highlight an unprecedented shift for Trickbot, and it's notable because threat groups in former Soviet Union states have typically avoided attacking targets in each other’s countries, IBM said.

Prior to the Russian invasion, ITG23, which is the name by which IBM tracks Trickbot, had not been known to target Ukraine. "Much of the group's malware was even configured to not execute on systems if the Ukrainian language was detected," IBM said in a report summarizing its findings this week. "ITG23's campaigns against Ukraine are notable due to the extent to which this activity differs from historical precedent and the fact that these campaigns appeared specifically aimed at Ukraine with some payloads that suggest a higher degree of target selection."

**Multiple Malware Tools**

IBM said it has observed Trickbot distributing several known malware tools such as IcedID, Cobalt Strike, AnchorMail, and Meterpreter in its attacks on Ukrainian targets. Some of the attacks involved the use of new tools such as a malicious Excel downloader, a self-extracting archive for dropping various malware payloads and a new malware encryption and obfuscation tool.

One of the two Trickbot campaigns that IBM uncovered was in early May. In those attacks, IBM observed the threat actor using a weaponized Excel file to download its AnchorMail backdoor on compromised systems. AnchorMail is a revamped version of Trickbot’s AnchorDNS, a backdoor that members of the closely affiliated Conti group have been using to deploy Conti ransomware. IBM X-Force researchers have previously described the malware as notable for communicating with its command-and-control (C2) server using the DNS protocol.

The second recent Trickbot campaign that IBM X-Force researchers spotted occurred likely in late May or early June. In that campaign, Trickbot actors used an ISO image file — or archive file containing the contents of an optical disk — as part of an attack chain to drop the Cobalt Strike post-exploit attack kit on target system. In June, Trickbot users were observed exploiting the so-called “Follina” zero-day bug in the Windows Microsoft Support Diagnostic Tool (MSDT) to deploy Cobalt Strike.

The campaigns that CERT-UA disclosed, and which IBM X-Force researchers analyzed, involved Trickbot attempts to deploy IcedID, a banking Trojan turned malware distributor; Metasploit attack payload, Meterpreter; and Cobalt Strike. In five of the six observed campaigns, Trickbot actors directly downloaded Cobalt Strike, AnchorMail, or Meterpreter on target systems — another break from their usual habit of deploying these tools as secondary payloads. IBM said the switch suggests "these attacks are part of targeted campaigns during which ITG23 is willing to immediately deploy higher-value backdoors."

IBM described the new malicious Excel downloader that Trickbot is using in the Ukrainian attacks as designed to download malware from a hard-coded URL. The downloader is stored as a macro within the Excel file and runs automatically if the file is opened — provided the user has macros enabled. The new dropper for AnchorMail that IBM observed is in the form of a WinRAR Self Extracting Archive. The dropper is rigged to extract and execute a script for building and configuring AnchorMail on infected systems.

Trickbot is a highly successful threat group that has been around since at least 2016. The group initially used its eponymously named malware to steal credentials to banking accounts. Over the years, the group evolved into a sort of initial access broker and a distributor for several ransomware and malware tools, most notably Conti and Ryuk and Emotet. Trickbot is used variously for stealing data, enabling cryptomining, enumerating systems, and other malicious activities.

Court documents in connection with the arrest of a key member of the group last year showed that nearly 20 cybercriminals — including several malware experts — collaborated in building the malware. A massive 2020 international law enforcement operation to take the threat actor down temporarily disrupted its activities but failed to stop them.

In Switch, Trickbot Group Now Attacking Ukrainian Targets

Acronyms serve as a gatekeeper — if you don't sling the lingo, you don't belong. So here's a quick guide to the letter salad of cloud cybersecurity.

**Question: There are so many cloud security acronyms nobody seems to be spelling out. What do they mean?**

**Answer:** Acronyms are confusing jargon that can often serve as a gatekeeper — if you don't sling the lingo, the thinking goes, you don't belong. But if you're reading this, you _do_ belong in cybersecurity, which has to become more welcoming if we ever hope to close the talent gap. So here's a quick guide to some of the acronyms you may come across when talking about cloud security.

**CDR – Cloud detection and response.** These tools continuously aggregate, normalize, and analyze data provided by SaaS (software-as-a-service) and cloud services about accounts, privileges, configurations, and activity to power insights, situational knowledge, and threat alerts. It provides single-pane visibility into cloud environments while maintaining user context.

**CIEM – Cloud infrastructure entitlement management.** Such tools address the issue of excessive permissions and entitlements to cloud resources. They detect over-permissioned accounts and roles and unused permissions and accounts. Note that this is distinct from SIEM (security information and event management), which analyzes alerts in real time, and CIAM (customer identity and access management), which aims to give users secure access to resources.

**CNAPP – Cloud-native application protection platform.** CNAPP addresses the inevitable increased number of moving parts and interlocking systems in cloud-native applications. Using a modular approach, existing CI/CD (continuous integration and continuous delivery) pipelines and runtime platforms can be extended and updated as better methods are discovered. Leveraging a CNAPP gives you in-depth, multilayered, agent-based, and agentless coverage across all aspects of your environment — everything from proactive validation of workloads to auditing policies on the public cloud platform you're running on. Providing more than just convergence of CIEM, CWPP, and CSPM (read on for more about the latter two), CNAPP allows CISOs (chief information security officers) to see the value that cloud security suites deliver, as opposed to a series of disjoint point solutions needing painstaking integration.

**CSPM – Cloud security posture management.** This refers to a set of controls that detect when your deployed accounts and resources deviate from best practices. CSPM tools embed a variety of standards that allow you to continuously evaluate all cloud accounts and workloads and quickly identify areas of drift and misconfiguration.

**CWPP – Cloud workload protection platform.** These protect workloads and focus on securing the entire application life cycle, providing cloud-based security solutions that protect instances on AWS, Google Cloud Platform, Microsoft Azure, and other cloud vendors' platforms. CWPP focuses on specific application use cases, such as runtime detection, system hardening, vulnerability management, network security, compliance, and incident response.

**SSPM – SaaS security posture management.** Such tools monitor security risks in SaaS applications. SSPM looks for and surfaces misconfigurations, compliance risks, unnecessary or defunct user accounts, excessive user permissions, and other cloud security issues so that security personnel can resolve them.

What Do All of Those Cloud Cybersecurity Acronyms Mean?

Dark Reading's digest of the other don't-miss stories of the week, including a new ransomware targeting QNAP gear, and a destructive attack against the College of the Desert that lingers on.

Cybercrime never sleeps — but editors do. To cap off this short Fourth of July week, Dark Reading's editors are collecting all of the interesting threat intelligence and cyber-incident stories that we just didn't get to earlier but would be remiss to not cover.  

We're talking a critical Cisco vulnerability, a Microsoft alert on upgrades to the Hive ransomware, QNAP issues, and a pair of cyberattacks.

In this week's "in case you missed it" (ICYMI) digest, read on for more about the following:

*   **Critical Cisco Security Vulnerability Allows Root Access to OS**
*   **Hive Ransomware Gets a Rust-y Upgrade**
*   **QNAP Warns on "Checkmate" Ransomware Attacks**
*   **"SHI-eesh": IT Giant Knocked Offline in Coordinated Cyberattack**
*   **California College Remains Offline After Ransomware Hit**

**Critical Cisco Security Vulnerability Allows Root Access to OS**

Cisco has rolled out patches for 10 security bugs, including a critical flaw that could allow cyberattackers to manipulate application source code, or configuration and critical system files.

The critical issue (CVE-2022-20812, CVSS severity score of 9.0) is a path-traversal vulnerability affecting the Cisco Expressway Series software and Cisco TelePresence VCS software, if they are in the default

"A vulnerability in the cluster database API of Cisco Expressway Series and Cisco TelePresence VCS could allow an authenticated, remote attacker with Administrator read-write privileges on the application to conduct absolute path traversal attacks on an affected device and overwrite files on the underlying operating system as a root user," according to the advisory, the latest since Cisco's last bug disclosure in May.

The vulnerability arises thanks to insufficient input validation of user-supplied command arguments, the networking giant noted.

"An attacker could exploit this vulnerability by authenticating to the system as an administrative read-write user and submitting crafted input to the affected command."

**Hive Ransomware Gets a Rust-y Upgrade**

The ransomware-as-a-service (RaaS) offering known as Hive has overhauled its infrastructure, using the programming language Rust.

That's the buzz from Microsoft, whose security researchers noted that Hive is an exemplar of adapting to the rapid change found in the underground economy.

"With its latest variant carrying several major upgrades, Hive also proves it’s one of the fastest-evolving ransomware families, exemplifying the continuously changing ransomware ecosystem," researchers said in a post this week. "The most notable changes include a full code migration to another programming language \[from GoLang to Rust\] and the use of a more complex encryption method."

Rust, a language also used by the BlackCat ransomware, allows advances in coding control, memory usage, resistance to reverse engineering, and access to a range cryptographic libraries, the researchers said.

As for the encryption, "the new Hive variant uses string encryption that can make it more evasive," according to the advisory. “The constants that are used to decrypt the same string sometimes differ across samples, making them an unreliable basis for detection.”

**QNAP Warns on "Checkmate" Ransomware Attacks**

QNAP, the network-attached storage (NAS) vendor, is flagging activity against its devices that results in the execution of the Checkmate ransomware.

The cyberattackers are specifically targeting SMB file-sharing services exposed to the Internet, using a dictionary attack to break accounts with weak passwords.

"Once the attacker successfully logs in to a device, they encrypt data in shared folders and leave a ransom note with the file name '!CHECKMATE\_DECRYPTION\_README' in each folder," according to QNAP's advisory this week. It added, "We are thoroughly investigating the case and will provide further information as soon as possible."

Customers of the Taiwan-based appliance maker have been suffering ongoing, relentless ransomware activity — which Dark Reading broke down earlier this week (along with potential defenses) in an extensive roundtable of experts.

To protect their businesses and avoid a ransomware checkmate, users should avoid exposing the SMB service to the internet and should employ strong passwords in any event.

**"SHI-eesh": IT Giant Knocked Offline in Coordinated Cyberattack**

IT-supplier bigwig SHI International said this week that it was the target of "a coordinated and professional malware attack."

The New Jersey-based vendor, which has 5,000 employees and 15,000 customers around the world, said that it moved quickly to stop the infection and minimize the impact on SHI’s systems and operations. That meant that some systems, such as SHI’s public websites and email, were knocked offline "while the attack was investigated and the integrity of those systems was assessed."

The SHI staff regained access to email, but as of Thursday the main website was still not operational. The company said in a website notice that IT teams continue to work to bring other systems back online.

It's unclear what the cyberattackers' goal was, but some researchers noted that a supply chain compromise attempt is a real possibility.

“Apart from being a large enterprise, SHI is a major software and hardware provider to several Fortune 500 companies, and while there is no evidence regarding third-party suppliers getting breached or customer data getting exfiltrated, this is certainly too close for comfort for many of their customers," Rajiv Pimplaskar, CEO at Dispersive Holdings, said via email.

**California College Remains Offline After Ransomware Hit**

As the latest example of what happens when IT isn't prepared for a hit, the 12,500-student College of the Desert, a community college in Palm Desert, Calif., remains offline after suffering which researchers suspect was a ransomware attack.

The cyberattack brought down the school's online services and campus phone lines on July 4. As of late Thursday, the school's website still returned a notice that it "is currently experiencing a system-wide outage of most services," including the ability for students to request transcripts, add or drop classes, or register for classes.

"Educational institutions have continued to be a prime target for ransomware groups over the last couple of years," says Josh Rickard, senior security solutions architect at Swimlane, noting that this is the second time College of the Desert has been hit with a malware attack; the first incident took place in August 2020. "To prevent similar attacks in the future and ensure that operations continue to run smoothly, education institutions such as College of the Desert need to devote more resources to information security teams, tools, processes, and products."

Rickard suspects the incident was ransomware due to the severe operational disruption, but it should be noted that College of the Desert has not confirmed that, admitting only to a "computer network disruption."

ICYMI: Critical Cisco RCE Bug, Microsoft Breaks Down Hive, SHI Cyberattack

New program offers free tech skills training and paid apprenticeships to make education and career pathways more accessible.

TULSA, OK -- Today Tulsa Community College (TCC) and Tulsa Innovation Labs (TIL), in partnership with edX, the global online learning platform from 2U, Inc. (Nasdaq: TWOU), and Skillstorm, launch the Cyber Skills Center. The new program, based in Tulsa, will develop a diverse talent pipeline for the in-demand and rapidly expanding career fields of cybersecurity and data analytics **at no-cost to Tulsa-area residents**.

Developed with edX’s Access Partnership initiative, Cyber Skills Center model is designed to streamline the skill development and career transition process for underserved communities. The program offers a 24-week online accelerated training boot camp curriculum offered by the Tulsa Community College, in partnership with edX, along with a paid apprenticeship upon graduation, and a suite of wrap-around services to make education and career transitions more accessible. These services, which are offered through the support of the George Kaiser Family Foundation, include childcare, transportation stipends, coaching and job readiness support.

The initial program is estimated to support more than 200 Tulsans over the next three years.

“Tulsa Community College has extensive experience and history of evolving with constant workforce changes and developing individuals with the needed skills for in-demand careers,” said Dr. Leigh Goodson, TCC president & CEO. “Boot camp graduates will not only be able to pursue new career opportunities after program completion, but can also apply credits earned from the boot camp to education opportunities to support additional reskilling and upskilling.”

The Cyber Skills Center will also lead to additional opportunities through college credit towards a 2-year associate degree through TCC, or bachelor’s degree at the University of Tulsa School of Cyber Studies or Oklahoma State University Spears School of Business.

Demand for careers in these fields are at an all-time high, for example, cybersecurity is expected to see a demand of nearly 3.5 million jobs by 2025.

With an average entry-level salary in this field in excess of $63,000 per year, according to the Bureau of Labor Statistics, and hundreds of available jobs in the greater Tulsa metropolitan area, there is an extraordinary opportunity to leverage the demand for cybersecurity talent to create a new pathway to the middle class.

“Our Access Partnerships help provide the infrastructure to bring colleges and universities, local workforce agencies and nonprofits, funding partners, and employers to the table to solve regional skills gaps and empower more working adults to succeed in the digital economy,” said Anant Agarwal, edX Founder and Chief Open Education Officer at 2U. “We are honored to welcome TCC as our first community college partner and look forward to working together with them and TIL to help reskill and upskill Tulsa area learners as the city continues to grow its tech community.”

**Upon completion of the 24-week program, graduates will be eligible to continue learning enterprise-level skills in cybersecurity and data analytics through SkillStorm’s 10-week immersive training program, which also provides potential opportunities to be connected with SkillStorm’s diverse group of commercial and federal clients.**

“Through our work with Fortune 500 companies across the country, we’ve seen rapidly accelerating demand for workers with cybersecurity and data analytics skills in an increasingly competitive labor market,” said Joe Mitchell, Chief Operating Officer at SkillStorm. “We look forward to the opportunity to help upskill individuals in the Tulsa community — and expand access to career pathways both in the region and with major employers nationwide.”

This effort builds on TIL’s strategy to create one of the more inclusive tech ecosystems in the country. By building the foundation for tech sectors where Tulsa has a competitive advantage: energy tech, advanced aerial mobility, virtual health, and cyber and analytics, and building accessible pipelines to each, Tulsa aims to serve as a new model for how tech growth can truly serve residents from diverse backgrounds and prepare the economy for the future.

"TIL is committed to making big investments where opportunities for traditionally underserved Tulsans overlap with industries in which Tulsa has a right to win,” said Nicholas Lalla, Managing Director of Tulsa Innovation Labs. “This initiative is a home run on both counts, and will be a game-changer in how the city leverages its unique competitive advantages to give Tulsans from every background a chance to access a high-paying career in cyber and data analytics."

To ensure the program meets the educational needs of diverse student populations in Tulsa, the Cyber Skills Center is working with nearly 30 nonprofits and community partners to provide feedback on program design and recruit students for the program. One such organization is Black Tech Street, a group advancing the digital transformation of historic Black Wall Street.

“No one should be intimidated by words like cyber and analytics,” said Tyrance Billingsley, the executive director of Black Tech Street. “People who excel in this field will be those who are creative, great at problem solving, and who have an eye for recognizing patterns. Cyber Security may sound scary and "elite" but it's not, and we want to demystify this world by making that clear. That's why this partnership was a no brainer. The Cyber Skills Center will be an incredible and accessible tool for helping Black Tulsans break into the tech world and will be crucial for our mission to rebirth Black Wall Street through technology”

The Cyber Skills Center will launch the first class in Fall 2022. To get started, apply at tulsacc.edu/cybercenter.

Cyber Skills Center Launches in Tulsa to Develop Diverse, Local Tech Talent Pipeline

The latest criminal use of a legitimate red-teaming tool helps attackers stay under the radar and better access living-off-the-land binaries.

In a fresh campaign that takes a page from the advanced persistent threat known as APT29, hackers are shifting away from the Cobalt Strike post-exploitation toolkit, instead embracing Brute Ratel C4 (BRc4).

BRc4 is the latest upstart in the red-team tooling world; like Cobalt Strike, it's an adversarial attack simulation tool designed for penetration testers. It’s a command-and-control (C2) framework that's not easily detected by endpoint detection and response (EDR) technology or other anti-malware tools.

A report from Palo Alto Networks' Unit 42 research team found evidence of attackers subverting Brute Ratel's free licensing protections and utilizing the tool to run criminal attack campaigns.

The infrastructure they uncovered is extensive, researchers noted.

"In terms of C2, we found that the sample called home to an Amazon Web Services (AWS) IP address located in the United States over port 443," they explained. "Further, the X.509 certificate on the listening port was configured to impersonate Microsoft with an organization name of 'Microsoft' and organization unit of 'Security.'"

Pivoting on the certificate and other artifacts, "we identified a total of 41 malicious IP addresses, nine BRc4 samples, and an additional three organizations across North and South America who have been impacted by this tool so far," they added.

**Living-Off-the-Land Techniques**

Unit 42 said the sample utilizing BRc4 uses known APT29 techniques, including well-known cloud storage and online collaboration applications. In this case, the sample studied was packaged up as a self-contained ISO that included a Windows shortcut LNK file, a malicious payload library, and a legitimate copy of Microsoft OneDrive Updater.

"Attempts to execute the benign application from the ISO-mounted folder resulted in the loading of the malicious payload as a dependency through a technique known as DLL search order hijacking," the report explained.

This technique of using legitimate tools and native utilities is known as "living off the land," and threat actors are increasingly using living-off-the-land binaries (LOLBins) to drop malicious payloads.

Last week for instance, researchers with Cyble reported an uptick in LNK file-based builders growing in popularity on Dark Web marketplaces, as various malware families lean on them for payload delivery.

"We have observed a steadily increasing number of high-profile threat actors shifting back to .LNK files to deliver their payloads," the Cyble researchers wrote. "Typically, threat actors use LOLBins in such infection mechanisms because it makes detecting malicious activity significantly harder."

**Where Red Team Tools Fit In**

Tools like Cobalt Strike and BRc4 aren't purely living-off-the-land approaches, "since you still have to introduce a piece of malware onto the system as opposed to using the operating systems built in tooling," explains Tim McGuffin, director of adversarial engineering at LARES Consulting.

However, these tools are nevertheless popular with attackers for their ability to evade detection mechanisms, fundamentally for the same reason as a living-off-the-land attack works — because they're otherwise viewed as legitimate software.

"Brute Ratel is an otherwise legitimate tool that might be present in victim networks," explains John Bambenek, principal threat hunter at Netenrich. "Since its use is likely whitelisted, it allows for attackers to operate more discretely than they would otherwise be able to do."

This is an unfortunate cycle that the security world has seen occur for a long time, as attackers are drawn to red-team tools like flies to honey.

According to Ivan Righi, senior cyber threat intelligence analyst for Digital Shadows, it's no surprise that BRc4 makes for an attractive tool. Not only does it have offensive security capabilities similar to Cobalt Strike that can be abused for malicious purpose, but it is also less known than Cobalt Strike.

"Many security solutions may not yet detect Brute Ratel as malicious, as opposed to Cobalt Strike, which is generally more well-known for being used for malicious purposes," Righi says.

According to McGuffin, security practitioners should be concerned about all toolkits like these, whether open source, commercial, or custom. But he believes that they shouldn't get caught up in the whack-a-mole game of detecting the framework or the tooling itself. Instead, they should focus on hardening their systems.

"An emphasis on endpoint hardening can be placed on prevention against any C2 tooling. An example is Microsoft's Attack Surface Reduction 'Application Allow-listing' guidance," he says. "The setting prevents unknown binaries from being introduced, and network egress hardening to prevent C2 callbacks to Command-and-Control servers."

Fortress Information Security Sponsors Open Web Application Security Project To Work on Industry-Wide Software Bill of Materials Standards

In a significant spike of activity, the state-sponsored group is going after intelligence on Russian government agencies.

Representing a significant increase in activity, a campaign linked to China started targeting Russia-linked organizations in June with malware designed to collect intelligence on government activities, according to analyses by security firms and Ukraine's Computer Emergency Response Team (CERT).   

The attacks use purported government advisories sent as Rich Text Files (RTFs) in an attempt to convince victims to open the documents, thus allowing a remote code execution (RCE) exploit in Microsoft Office to be run. That's according to endpoint security firm SentinelOne, which stated in an analysis published on Thursday that the contents of the documents appear as security warnings written in Russian. They claim to warn agencies and infrastructure providers of potential attacks and advise them of compliance requirements under Russian law.

**Escalating Cyberattacks Against Russia**

While China has targeted Russia in the past, and vice versa, the pace of attacks — especially by the purported threat actor, Tonto Team — has grown following the Russian invasion of Ukraine, says Tom Hegel, a senior threat researcher at SentinelOne.

"Tonto Team, like other Chinese actors, has a long history of targeting Russia," he says. "What we're seeing here is a potential Chinese government increase in intelligence collection requirements from inside Russia. Perhaps an increased prioritization or expansion of resources assigned to such tasking."

The reported increase in Chinese cyber operations comes as Russia has strengthened diplomatic relations with China in the face of sanctions from Western nations. While the two major nations are not formal allies, they have expanded trade and defense ties over the past decade as a way to foil the expansion of Western alliances.

In addition, they have different approaches to pursuing their foreign policy goals. Russia has tacitly allowed cybercriminal gangs to operate in its territory and has also widely used cyber operations to steal intelligence and attack infrastructure, as well as an adjunct to military operations. For example, Russia has used disinformation campaigns, infrastructure attacks, and espionage operations in its conflict with Ukraine.

China, which has profited significantly from economic relations with Western nations, has mainly pursued non-military approaches to international relations and used cyber operations for acquiring intellectual property and conducting espionage. Treating Russia as any other adversary just shows consistency, says SentinelOne's Hegel.

This is "simply China looking out for itself in uncertain times," he says. "Like any well-resourced nation, they seek to support their own agenda through cyber, and the state of affairs in Russia may be adjusting just what they prioritize."

**Technical Breadcrumbs Point to China**

The recent campaigns have used two pieces of malware linked to Chinese advanced persistent threats (APTs): a toolkit used to build malicious documents known as Royal Road and a custom remote access Trojan (RAT) known as Bisonal used by Chinese actors. The Tonto Team — also known as Karma Panda and Bronze Huntley — traditionally has focused on other Asian nations, such as South Korea and Japan, as well as the United States and Taiwan. Recently, the group has increased its operations to Russia, Pakistan, and other nations.

While false flag operations, where one adversary attempts to disguise their operations as another attacker, have happened, a variety of evidence links the attacks to China.

At least seven threat groups — all linked to China — use Royal Road to create malicious documents as part of the initial attack aimed at gaining access to targeted systems. In April, for example, cyberthreat intelligence firm DomainTools analyzed an document created with the Royal Road malware building toolkit that had the hallmarks of a Chinese espionage campaign and targeted a Russian underwater research and weapons development organization.

"Combined with the sensitive targeting and the attempts at hardening the ultimate payload, it appears the adversary went to some effort to evade analysis of their activity as well," the analysis stated. "Although this campaign appears specifically targeted to an entity in the Russian Federation, the underlying behaviors of this campaign — from malicious document usage through binary execution guardrails and controls — provide helpful insight into adversary tradecraft from which all defenders can learn valuable lessons."

In addition, Bisonal is used exclusively by Chinese groups, according to the advisories.

Companies should take note that nation-state attacks can often affect private businesses. The SentinelOne advisory has indicators of compromise (IoCs) for the latest campaigns, and DomainTools highlights various countermeasures for detecting and blunting cyber-espionage attacks.

Organizations should use the intelligence to check their own defenses against similar attacks, says SentinelOne's Hegel.

"Targets of espionage or disruption in today's world are not isolated to government networks but can overflow or directly hit private business simply because of their stance on a political issue or where they operate," he says. "As we observed when Ukraine was invaded, things can shift overnight — so CISOs should remain aware of this activity as we continue to live with such geopolitical tension."

Improper implementations of authentication APIs at a global crypto wallet service provider could have resulted in the loss of account control — and millions of dollars — from personal and business accounts.

A cryptocurrency wallet service provider serving more than 2 million users worldwide and managing about $3 billion worth of Bitcoin was found to contain API vulnerabilities tied to how external authentication logins were implemented. 

The bugs are fixed, but the discovery illustrates the high stakes involved in implementing APIs securely, researchers say — and the difficulties in doing so.  

According to a report shared with Dark Reading from Salt Labs, the research division of Salt Security, a series of vulnerabilities (CVEs were not assigned) could have allowed actors take over a large portion of a user's account in the system.  

This vulnerability would have given a malicious actor full access, along with the ability to perform multiple financial actions on behalf of that user, including the transfer of funds to any location of their choice.

"Once we successfully logged in to a user's accounts, we can potentially use any functionality available to the user, including funds transfer, viewing transactions history, seeing the user's personal data, which might include name, address, bank account number, and other valuable data," Salt researchers note in the report.

The first bug involved the common feature found in mobile apps that allow users to log in using an external service, like Apple ID, Google, Facebook, or Twitter. In this case, the researchers examined the "log in with Google" option — and found that the authentication token mechanism could be manipulated to accept a rogue Google ID as being that of the legitimate user.

The second bug allowed researchers to get around two-factor authentication. A PIN-reset mechanism was found to lack rate-limiting, allowing them to mount an automated attack to uncover the code sent to a user's mobile number or email.

"This endpoint does not contain any sort of rate limiting, user blocking, or temporary account disabling functionality. Basically, we can now run the entire 999,999 PIN options and get the correct PIN within less than 1 minute," according to the researchers.

Each security issue on its own provided limited abilities to the attacker, according to the report. "However, an attacker could chain these issues together to propagate a highly impactful attack, such as transferring the entire account balance to his wallet or private bank account."

Yaniv Balmas, vice president of research at Salt, explains there are two factors that made these vulnerabilities impactful and dangerous.

"First, it is very easily exploitable, and second, a successful exploitation could lead to millions of dollars — or more — being stolen from personal and business accounts," he says.

**Poor API Implementations: An Important Object Lesson**

As noted, the wallet-provider quickly fixed the API implementations in question, but there are important takeaways from the analysis, Balmas explains. After all, as the entire cryptocurrency market is relatively young, most of the services in this domain are heavily dependent on APIs as part of their core technologies.

"I have yet to see any cryptocurrency service that does not publish some sort of API to ease automated interactions with its functionalities," he says. “This reliance on APIs in turn surfaces another problem."

He explains API are designed to be dynamic and rapidly evolving interfaces for core business functionalities, which is obviously very positive from the user perspective.

"However, this same behavior opens the door for many security issues and vulnerabilities that may go unnoticed," he says. "Hence, we see with great frequency in our research efforts a relatively poor state of API security, sometimes with serious business implications."

**API Security Issues a Major Concern as Usage Grows**

As agile development grows in popularity, organizations are turning to APIs, resulting in broader attack surfaces more vulnerable to exploitation by threat actors. A recent analysis by application security firm Imperva and risk-strategy firm Marsh McLennan of breaches involving APIs revealed US companies face a combined $12 billion to $23 billion in losses in 2022.

Meanwhile, a March report from Salt Labs found API attacks increased a whopping 681% in the last year, with API attack traffic growing at more than twice the rate of nonmalicious traffic. Again, much of that could be due to implementation and configuration error: In May, for instance, Shadowserver Foundation researchers discovered that 380,000 Kubernetes API servers were open to the public Internet, representing 84% of all global Kubernetes API instances observable online.

**API Attack Surface Must Be Tracked, Monitored**

Balmas notes another issue with APIs and their nature is that once an API ecosystem gets big, it becomes very hard to have a complete handle on it. With multiple applications and internal services each publishing their own unique sets of APIs, it is very hard for the maintainers sometimes to even know which APIs are published at any given point in time.

"This is why API visibility and consolidation measures are sometimes the very first — and important — step to securing a company's APIs," he says.

Balmas recommends that cryptocurrency platforms, and any other heavy API users, should start paying more attention to the API attack surface that they expose.

"This new attack surface should be carefully tracked and monitored," he adds. "The services behind it should be more carefully reviewed on a periodic basis to make sure no new security issues have been introduced, and behavioral monitoring should be applied on the ongoing traffic to spot anomalies that might be happening in an effort to find and exploit vulnerabilities."

When examining the modern threat landscape, empowering your security operations and overcoming the limitations inherent with other malware prevention solutions is imperative.

The implementation of defense-in-depth architectures and operating system hardening technologies have altered the threat landscape. Historically, zero-click, singular vulnerabilities were commonly discovered and exploited. The modern-day defensive posture requires attackers to successfully chain together multiple exploit techniques to gain control of a target system. The increased utilization of dynamic analysis systems has driven attackers to evade detection by requiring input or action from the user. Sometimes, the victim must perform several manual steps before the underlying payload is activated. Otherwise, it remains dormant and undetectable through behavioral analysis.

It is well known that client-side attacks are the predominant access vector for most initial access. Web browser and email-based malware campaigns target users through phishing, social engineering, and exploitation. Productivity and business tools from vendors like Adobe and Microsoft are widespread and provide attackers with many options. Combining the lack of security awareness training and well-developed social engineering tactics frequently results in users permitting the execution of malicious embedded logic like weaponized macros or other scripts. Analysis of these common malware carriers is time-consuming and tedious, and it requires expert skills. To adequately prevent, detect, and respond to these threats, an organization must throw everything at the problem and augment this previously human-intensive process.

Deep File Inspection (DFI) is one approach to ease the burden associated with continuous security monitoring. DFI is a static-analysis engine that inspects beyond Layer 7 of the OSI model, essentially automating the work of your typical SOC analyst or security researcher. Regardless of the complexity of evasive techniques a threat actor utilizes, DFI dissects malicious carriers to expose embedded logic, semantic context, and metadata. Coercive graphical lures are extracted and processed through a machine vision layer, adding to the semantic context of the original file. Commonly used obfuscation methods and encoding mechanisms are automatically discovered and deciphered.

A public concern that SOC analysts, IR teams, and security researchers encounter is the limited availability of context for detection analytics. In the case of intrusion prevention systems, resources are limited to microseconds of time and kilobytes of analyzable data. Intrusion detection systems can typically dig deeper, taking additional milliseconds to expose further data.

Regarding the time-analysis trade-off, the next step up is behavioral monitoring or sandboxed execution. This class of solutions detonates samples in a virtualized environment and annotates the system's behavior for threat detection; this process is both compute- and time-intensive, taking minutes to analyze each file. There is a middle ground where a few additional seconds can provide previously unseen detection opportunities.  

**Use Case: Qbot Malware Delivered via Follina and Malspam**

An example of an evasive threat is the recent TA570 campaigns that delivered Qbot malware with thread-hijacked emails. This wave of malspam utilized two different methods to provide the payload. The first method used a shortcut LNK to run a DLL with the hidden attribute. The second method is a Word document using the Follina (CVE-2022-30190) exploit.

The attached HTML file contains an antiquated JS function to convert the embedded base64 string into a zip archive and prompt the victim to download. When extracted, the zip file contains a disk image that will be mounted showing either a shortcut or the shortcut and word document. The shortcut will execute the Qbot DLL within the directory with the hidden attribute set. At the same time, the Word file will attempt to exploit the MSDT vulnerability and download the payload from a remote server.

It is challenging for many solutions to carve the zip archive from the encoded HTML, extract the IMG file, and identify the weaponized contents. In this example, multiple threat signatures are seen from ambiguities within the SMTP headers, down to the hidden DLL or Follina document.

Another interesting approach for detection is the concept of retrospective analysis or RetroHunting. While DFI creates a new dimension of data, RetroHunting provides a new dimension of time for analyzing historical events. The appearance of Follina and other zero-day vulnerabilities illustrates the usefulness of this capability by facilitating the detection of previously unseen alerts with emerging threat intelligence and detection logic.

In addition to a library of predeveloped signatures, analysts can develop user-defined YARA rules to combine strings, bytes patterns, and regular expressions via flexible conditional logic.

When confronted with novel attack techniques being encountered in the wild, security leaders must provide an opportunity to empower your detection operations and overcome the limitations inherent with other malware prevention solutions. A free resource to test the efficacy of a mail provider's security controls is the Email Security Assessment.
