The APT is pairing a known Microsoft flaw with a malicious document to load malware that nabs credentials from Chrome, Firefox and Edge browsers.

The APT is pairing a known Microsoft flaw with a malicious document to load malware that nabs credentials from Chrome, Firefox and Edge browsers.

Advanced persistent threat group Fancy Bear is behind a phishing campaign that uses the specter of nuclear war to exploit a known one-click Microsoft flaw. The goal is to deliver malware that can steal credentials from the Chrome, Firefox and Edge browsers.

The attacks by the Russia-linked APT are tied the Russian and Ukraine war, according to researchers at Malwarebytes Threat Intelligence. They report that Fancy Bear is pushing malicious documents weaponized with the exploit for Follina (CVE-2022-30190), a known Microsoft one-click flaw, according to a blog post published this week.

“This is the first time we’ve observed APT28 using Follina in its operations,” researchers wrote in the post. Fancy Bear is also known as APT28, Strontium and Sofacy.

On June 20, Malwarebytes researchers first observed the weaponized document, which downloads and executes a .Net stealer first reported by Google. Google’s Threat Analysis Group (TAG) said Fancy Bear already has used this stealer to target users in the Ukraine.

The Computer Emergency Response Team of Ukraine (CERT-UA) also independently discovered the malicious document used by Fancy Bear in the recent phishing campaign, according to Malwarebytes.

****Bear on the Loose****

CERT-UA previously identified Fancy Bear as one of the numerous APTs pummeling Ukraine with cyber-attacks in parallel with the invasion by Russian troops that began in late February. The group is believed to be operating on the behest of Russian intelligence to gather info that would be useful to the agency.

In the past Fancy Bear has been linked in attacks targeting elections in the United States and Europe, as well as hacks against sporting and anti-doping agencies related to the 2020 Olympic Games.

Researchers first flagged Follina in April, but only in May was it officially identified as a zero-day, one-click exploit. Follina is associated with the Microsoft Support Diagnostic Tool (MSDT) and uses the ms-msdt protocol to load malicious code from Word or other Office documents when they’re opened.

The bug is dangerous for a number of reasons–not the least of which is its wide attack surface, as it basically affects anyone using Microsoft Office on all currently supported versions of Windows. If successfully exploited, attackers can gain user rights to effectively take over a system and install programs, view, change or delete data, or create new accounts.

Microsoft recently patched Follina in its June Patch Tuesday release but it remains under active exploit by threat actors, including known APTs.

**Threat of Nuclear Attack**

Fancy Bear’s Follina campaign targets users with emails carrying a malicious RTF file called “Nuclear Terrorism A Very Real Threat” in an attempt to prey on victims’ fears that the invasion of Ukraine will escalate into a nuclear conflict, researchers said in the post. The content of the document is an article from the international affairs group Atlantic Council that explores the possibility that Putin will use nuclear weapons in the war in Ukraine.

The malicious file uses a remote template embedded in the Document.xml.rels file to retrieve a remote HTML file from the URL http://kitten-268\[.\]frge\[.\]io/article\[.\]html. The HTML file then uses a JavaScript call to window.location.href to load and execute an encoded PowerShell script using the ms-msdt MSProtocol URI scheme, researchers said.

The PowerShell loads the final payload–a variant of the .Net stealer previously identified by Google in other Fancy Bear campaigns in the Ukraine. While the oldest variant of the stealer used a fake error message pop-up to distract users from what it was doing, the variant used in the nuclear-themed campaign does not, researchers said.

In other functionality, the recently seen variant is “almost identical” to the earlier one, “with just a few minor refactors and some additional sleep commands,” they added.

As with the previous variant, the stealer’s main pupose is to steal data—including website credentials such as username, password and URL–from several popular browsers, including Google Chrome, Microsoft Edge and Firefox. The malware then uses the IMAP email protocol to exfiltrate data to its command-and-control server in the same way the earlier variant did but this time to a different domain, researchers said.

“The old variant of this stealer connected to mail\[.\]sartoc.com (144.208.77.68) to exfiltrate data,” they wrote. “The new variant uses the same method but a different domain, www.specialityllc\[.\]com. Interestingly both are located in Dubai.”

The owners of the websites most likely have nothing to do with APT28, with the group simply taking advantage of abandoned or vulnerable sites, researchers added.

Fancy Bear Uses Nuke Threat Lure to Exploit 1-Click Bug

Users call for security update back-port to support earlier versions

Emma Woollacott 23 June 2022 at 12:03 UTC

Users call for security update back-port to support earlier versions

Data monitoring and search vendor Splunk patched a code execution vulnerability in its Splunk Enterprise deployment server and is – belatedly, according to some – promising to back-port it to earlier versions.

The deployment servers are used to distribute configurations and content updates to Enterprise instances such as forwarders, indexers, and search heads.

However, a critical-severity vulnerability, CVE-2022-32158, meant that versions prior to 9.0 allow clients to leverage the server to deploy forwarder bundles to other clients.

An attacker who had compromised or had access to a single universal forwarder within an environment could then execute arbitrary code on all the other Universal Forwarder (UF) endpoints within that organization.

Nick Heudecker, senior director, market strategy, and competitive intelligence at Cribl, told The Daily Swig: "It’s not uncommon for Splunk users to have thousands or tens of thousands of UFs deployed across their infrastructure, making this a high priority vulnerability."

Splunk said there's no evidence that the vulnerability has been exploited in the wild, and that the Splunk Cloud Platform (SCP) isn't affected as it doesn't offer nor use deployment servers.

"Splunk released fixed versions for impacted products that mitigate the issues, and we strongly encourage customers to upgrade as soon as possible," it said in a statement.

Catch up on the latest vulnerability-related security news and analysis

The vulnerability affects all Splunk Enterprise deployment servers prior to version 9.0 – and there's currently no patch or workaround other than to update to this version, released only on 14 June. With patching, users would need to restrict access to the deployment server, firing it up only to push configuration updates.

Under pressure from the community, Splunk has now said that it plans to back-port the fix to earlier versions, though there's no indication as to when.

"While the vulnerability is a problem, how Splunk chose to handle it is what has upset Splunk’s users and community," according to Heudecker. "Vulnerabilities happen. How a company reacts to them can create or destroy goodwill."

Splunk patches critical vulnerability while users push for legacy updates

The credential-phishing attack leverages social engineering and brand impersonation techniques to lead users to a spoofed MetaMask verification page.

Researchers have uncovered an email-based credential-phishing attack targeting users of MetaMask, a cryptocurrency wallet used to interact with the Ethereum blockchain.

The campaign is directed at Microsoft 365 (formerly Microsoft Office 365) users and has targeted multiple organizations across the financial industry. It starts with a socially engineered email that looks like a MetaMask verification email, according to the Armorblox research team, containing a link.

Upon clicking the link, users are taken to a spoofed MetaMask verification page, where they are asked to verify their wallet, claiming that non-compliance would result in limited access to their wallets.

The fake landing page uses MetaMask logos and branding to closely resemble the real log-in page, and it deploys a language of urgency to encourage compliance with the Know Your Customer (KYC) verification request.

"In order to get the victim to comply with the request and exfiltrate sensitive data, attackers included language within both the body of the email and the fake landing page that denoted a sense of urgency, making it known that time was of the essence," the Armorblox post notes.

The research team also pointed out that the attack leverages the curiosity effect, a cognitive bias that can be used to exploit the user's inherent urge to resolve doubt.

"Each further engagement through the attack flow further aimed to increase this trust through legitimate logo inclusions, branding, and key attributes that are only affiliated with the spoofed brand," the post continues.

**Attack Skates Past Microsoft Security**

Even though the email came from an invalid domain, the attackers were still able to slip through Microsoft's security controls, using a "gamut of techniques" to bypass secure email gateway (SEG) filters.

Armorblox CSO Brian Johnson notes while the company's research team does not have access to Microsoft threat detection details, they have seen a large amount of modern attacks spawn zero-day malicious links that are ephemeral in nature.

"With the advent of cloud services, it is easy to spin up and spin down malicious links in minutes," he explains. "These attacks can only be detected when you combine natural language understanding with artificial intelligence to go beyond static checks on known malicious links."

To protect against these types of attacks, Johnson says the basic steps include ensuring multifactor authentication (MFA) across all the organization's accounts — specifically, the ones that provide access to financial accounts.

The Armorblox post also recommends keeping an eye out for social-engineering cues, for example any logical inconsistencies within the email, and to augment native email security with additional controls.

**Cryptocurrency Attacks Evolving, Targeting Startups**

Johnson adds that crypto-wallet phishing has become more targeted and mainstream.

"As the use of cryptocurrency gains traction in both personal and business environments, it opens up another vector for malicious actors," Johnson warns.

Hackers' approaches to compromising cryptocurrency and digital asset exchanges continue to evolve, as a series of attacks against small and midsize businesses has led to major cryptocurrency losses for the victims.

Among these malicious actors is BlueNoroff, an advanced persistent threat (APT) group that's part of the larger Lazarus Group associated with North Korea, which carried out the SnatchCrypto campaign in January.

Meanwhile, cryptocurrency mixing — a technique that uses pools of cryptocurrency to complicate the tracking of electronic transactions — is set to grow, as ransomware and other cybercriminal enterprises increasingly lean into cryptocurrency, a November 2021 report from Intel 471 warned.

MetaMask Crypto-Wallet Theft Skates Past Microsoft 365 Security

Researchers have spotted the threat group, also known as Fancy Bear and Sofacy, using the Windows MSDT vulnerability to distribute information stealers to users in Ukraine.

Russia’s notorious advanced persistent threat group APT28 is the latest in a growing number of attackers trying to exploit the “Follina” vulnerability in the Microsoft Support Diagnostic Tool (MSDT) in Windows.

Researchers from Malwarebytes this week observed the threat actor — aka Fancy Bear and Sofacy — sending out a malicious document with an exploit for the now-patched flaw (CVE-2022-30190) via phishing emails to users in Ukraine. The document was titled “Nuclear Terrorism A Very Real Threat.rtf" and appeared designed to prey on fears about the war in Ukraine spiraling into a nuclear holocaust. 

Malwarebytes identified the contents of the document as a May 10 article from the Atlantic Council on the potential for Russian President Vladimir Putin to use nuclear weapons in Ukraine.

Users who opened the document ended up having a new version of a previously known .Net credential stealer loaded on their systems via the Follina exploit, which made headlines as a zero-day earlier this month. The malware is designed to steal usernames, passwords, and URLs from Chrome and Microsoft Edge browsers. It can also grab all stored cookies in Chrome, Malwarebytes researchers say.

Ukraine’s Computer Emergency Response Team (CERT-UA) separately warned of the same threat. In an advisory, it said it had spotted APT28 using the same malicious document that Malwarebytes reported to try and distribute the CredoMap credential-stealing malware to users in Ukraine. 

Available telemetry suggests that the adversary has been using the document since at least June 10, CERT-UA says.

“The target, and the involvement of APT28, (a division of Russian military intelligence), suggests that campaign is a part of the conflict in Ukraine, or at the very least linked to the foreign policy and military objectives of the Russian state,” states Malwarebytes in a report Tuesday on the new activity.

**The Follina Feeding Frenzy**

The Follina bug in MSDT exists in all current versions of Windows and can be exploited via malicious Microsoft Office documents. To trigger it, all an attacker needs to do is call MSDT from an Office app, such as Word, using the URL protocol. Attackers can exploit the flaw to gain remote control of vulnerable systems and take a variety of malicious actions on them, including executing malicious code, installing programs, modifying data, and creating new accounts. 

Microsoft disclosed the flaw in late May amid widespread zero-day exploit activity. The company finally issued a fix for the vulnerability in its Patch Tuesday set of monthly security updates for June.

Malwarebytes describes the Ukrainian campaign as the first time it had observed APT28 exploiting Follina. But numerous other groups, including other state-backed actors, have been actively exploiting the vulnerability in recent weeks.

Many of the attacks have targeted Ukrainian entities. Earlier this month, for instance, CERT-UA warned about a threat actor — likely Russia’s Sandworm APT group — using a Follina exploit in a “massive cyberattack” targeting media organizations in Ukraine. 

And just this week, CERT-UA warned about a threat group it is tracking as UAC-0098, which is targeting critical infrastructure facilities in Ukraine with a tax-themed document carrying a Follina exploit. According to the CERT-UA, the attackers in this campaign are exploiting Follina to drop the Cobalt Strike Beacon post-compromise attack tool on compromised systems.

Other reports of Follina-related activity have emerged as well, suggesting the flaw is of high interest to attackers and needs to be addressed quickly. Earlier this month, Proofpoint reported that it had blocked a likely stated-backed phishing campaign involving a Follina exploit that targeted a handful of its customers. The phishing email masqueraded as a document about a salary increase, which if opened would have resulted in a PowerShell script being downloaded to the system.

Symantec, too, has reported observing a variety of threat actors exploiting Follina to distribute different malicious payloads, including the AsyncRAT remote access Trojan and another unnamed malware for stealing cookies and save login data from browsers such as Chrome, Edge and Firefox.

Zscaler Adds New AI/ML Capabilities for the Zscaler Zero Trust Exchange

Using WebAuthn, physical keys, and biometrics, organizations can adopt more advanced passwordless MFA and true passwordless systems. (Part 2 of 2)

_The first article of this two-part series examined ways to improve multifactor authentication (MFA) and boost adoption. This story takes a look at how organizations can adopt more advanced passwordless MFA and true passwordless systems._

Getting to passwordless won't be easy, but the concept is finally gaining momentum. Although several vendors have offered passwordless MFA and true passwordless technology for a few years — mostly relegated to enterprise use — a more comprehensive framework is now taking shape. Apple, Google, and Microsoft have jointly agreed to adopt passwordless in earnest.

For example, Apple will be introducing Passkeys, which completely replace passwords used to log into websites, in a few months. The framework, based on the FIDO Alliance standard, uses biometrics such as Face ID to generate a unique, encrypted digital key that resides only on the device and within an encrypted keychain used for other Apple devices, including the iPhone, iPad, Mac, and Apple TV. This makes it impervious to phishing and other forms of data extraction.

In 2020, Microsoft turned to biometrics for authentication in Windows 10 and Windows 365 — and the company is also expanding passwordless to websites. In addition, all three companies are adding the ability to transfer this identity data across authenticated devices and systems. In the past, changing phones or other devices typically meant reinstalling credentials — a time-consuming and irritating task.

In addition to building biometrics and other security mechanisms into their operating systems, the Big Three are introducing software development kits (SDKs) that companies can use to build passwordless websites. As a result, it will soon be possible for consumers to begin ditching passwords for compliant sites and services. Like Apple's Passkey, a mobile phone or other registered device authenticates the person and then sends the request to the server without sending the biometric data.

"Where the big vendors lead, everyone else follows," says Don Tait, a senior analyst for Omdia.

At the heart of this transformation is the FIDO Alliance. "It is a classic example of the impact of consumerization on technology," adds Rik Turner, a senior analyst at Omdia. "As people begin to use tools in their private lives, they begin to seep into the workplace."

**A Matter of Identity**

Security experts say that the first step in building a better authentication framework is to stop using outdated methods like secret words and one-time codes to verify users. Even push apps are vulnerable to exploits. For example, crooks who gain access to a company's network or an MFA system can generate fake authentication requests that someone might authorize in a moment of distraction or inattentiveness.

Even highly secure YubiKeys and other U2F tokens aren't exempt from vulnerabilities and workarounds. For example, if a user forgets the key or can't use it for some reason, the typical workaround is to revert to a text code or less secure form of MFA as the backup. At that point, even an ultra-secure digital token can't provide protection.

A deeper and broader use of biometrics and user verification methods, including presence-based authentication and behavioral or activity-based models, is key. This includes the use of the FIDO protocol WebAuthn, which delivers an API that supports strong, public-key cryptography registration and authentication. It can be combined with a continuous authentication method that reverifies the identity of the session through a persistent token.

Several companies, including Beyond Identity, Veriff, 1Kosmos, and Jumio, have adopted this type of approach. They rely on FIDO standards that tie into biometrics, along with a highly secure identity proofing method. Typically, they ask users to provide a document such as a driver's license or a passport, which is securely stored in an app on the device. A selfie or face scan ensures that everything matches and authenticates the user.

For example, Veriff, which works in 190 countries, in 35 languages, and with 8,000 IDs, runs an online blockchain-based identity verification within a few seconds. It uses an AI-supported decision engine that incorporates real-time feedback through a document check, biometric scan, face comparison, background video, and device and network analytics. Financial institutions, healthcare providers, and others that use the technology can also reduce fake accounts and fraud.

"This creates a barrier that is much more difficult for an intelligent and determined bad actor to bypass," says Kalev Rundu, senior product manager at Veriff. "People today are much more willing to use biometrics for authentication, but they are only ready to do it if they receive real value in return and they can maintain control over how and where their data is used."

**Forward Thinking**

The move to passwordless MFA and true passwordless remains a slow march. For now, advanced authentication is more viable within the enterprise, where it's a closed and controlled environment. Michael Engle, co-founder and CSO at passwordless MFA solutions vendor 1kosmos, estimates that 80% of passwords can be eliminated almost immediately with the right strategy and tools.

For now, Omdia analysts Tait and Turner recommend migrating to passwordless MFA without delay. Not only does the framework deliver a better and safer customer experience, but it can also drive revenue growth, they argue. In addition, it's wise to phase in true passwordless systems and build on them through the FIDO Alliance, as well through Apple Passkeys and the equivalent passwordless systems at Google and Microsoft.

Along the way, it's also essential to educate customers and employees about passwordless authentication and ensure that people understand that their biometric data is being used as their gateway to apps and the Internet. The combination of better UX, incentives, and more streamlined processes can, over the long term, boost security, improve trust, and trim security costs.

Says Jasson Casey, CTO for Beyond Identity: "In the end, the objective isn't to eliminate passwords, though that's a noble cause. It's to create better security and a safer computing environment for everyone."

Evolving Beyond the Password: Vanquishing the Password

Authorities in the United States, Germany, the Netherlands and the U.K. last week said they dismantled the "RSOCKS" botnet, a collection of millions of hacked devices that were sold as "proxies" to cybercriminals looking for ways to route their malicious traffic through someone else's computer. While the coordinated action did not name the Russian hackers allegedly behind RSOCKS, KrebsOnSecurity has identified its owner as a Russian man living abroad who also runs the world's top Russian spamming forum.

Authorities in the United States, Germany, the Netherlands and the U.K. last week said they dismantled the “**RSOCKS**” botnet, a collection of millions of hacked devices that were sold as “proxies” to cybercriminals looking for ways to route their malicious traffic through someone else’s computer. While the coordinated action did not name the Russian hackers allegedly behind RSOCKS, KrebsOnSecurity has identified its owner as a 35-year-old Russian man living abroad who also runs the world’s top spam forum.

The RUSdot mailer, the email spamming tool made and sold by the administrator of RSOCKS.

According to a statement by the **U.S. Department of Justice**, RSOCKS offered clients access to IP addresses assigned to devices that had been hacked:

“A cybercriminal who wanted to utilize the RSOCKS platform could use a web browser to navigate to a web-based ‘storefront’ (i.e., a public web site that allows users to purchase access to the botnet), which allowed the customer to pay to rent access to a pool of proxies for a specified daily, weekly, or monthly time period. The cost for access to a pool of RSOCKS proxies ranged from $30 per day for access to 2,000 proxies to $200 per day for access to 90,000 proxies.”

The DOJ’s statement doesn’t mention that RSOCKS has been in operation since 2014, when access to the web store for the botnet was first advertised on multiple Russian-language cybercrime forums.

The user “RSOCKS” on the Russian crime forum **Verified** changed his name to RSOCKS from a previous handle: “**Stanx**,” whose very first sales thread on Verified in 2016 quickly ran afoul of the forum’s rules and prompted a public chastisement by the forum’s administrator.

Verified was hacked twice in the past few years, and each time the private messages of all users on the forum were leaked. Those messages show that after being warned of his forum infraction, Stanx sent a private message to the Verified administrator detailing his cybercriminal bona fides.

“I am the owner of the RUSdot forum (former Spamdot),” Stanx wrote in Sept. 2016. “In spam topics, people know me as a reliable person.”

A Google-translated version of the Rusdot spam forum.

RUSdot is the successor forum to **Spamdot**, a far more secretive and restricted forum where most of the world’s top spammers, virus writers and cybercriminals collaborated for years before the community’s implosion in 2010. Even today, the RUSdot Mailer is advertised for sale at the top of the RUSdot community forum.

Stanx said he was a longtime member of several major forums, including the Russian hacker forum **Antichat** (since 2005), and the Russian crime forum **Exploit** (since April 2013). In an early post to Antichat in January 2005, Stanx disclosed that he is from **Omsk**, a large city in the Siberian region of Russia.

According to the cyber intelligence firm Intel 471, the user Stanx indeed registered on Exploit in 2013, using the email address **stanx@rusdot.com**, and the ICQ number **399611**. A search in Google for that ICQ number turns up a cached version of a Vkontakte profile for a **Denis “Neo” Kloster**, from Omsk, Russia.

Cybersecurity firm Constella Intelligence shows that in 2017, someone using the email address **istanx@gmail.com** registered at the Russian freelancer job site **fl.ru** with the profile name of “**Denis Kloster**” and the Omsk phone number of **79136334444**. Another record indexed by Constella suggests Denis’s real surname may in fact be “**Emilyantsev**” \[Емельянцев\].

That phone number is tied to the WHOIS registration records for multiple domain names over the years, including **proxy\[.\]info**, **allproxy\[.\]info**, **kloster.pro** and **deniskloster.com**.

A copy of the passport for Denis Kloster, as posted to his Vkontakte page in 2019. It shows that in Oct. 2019, he obtained a visa from the American Embassy in Bangkok, Thailand.

The “about me” section of DenisKloster.com says the 35-year-old was born in Omsk, that he got his first computer at age 12, and graduated from high school at 16. Kloster says he’s worked in many large companies in Omsk as a system administrator, web developer and photographer.

According to Kloster’s blog, his first real job was running an “online advertising” firm he founded called **Internet Advertising Omsk** (“**riOmsk**“), and that he even lived in New York City for a while.

“Something new was required and I decided to leave Omsk and try to live in the States,” Kloster wrote in 2013. “I opened an American visa for myself, it was not difficult to get. And so I moved to live in New York, the largest city in the world, in a country where all wishes come true. But even this was not enough for me, and since then I began to travel the world.”

The current version of the About Me page on Kloster’s site says he closed his advertising business in 2013 to travel the world and focus on his new company: One that provides security and anonymity services to customers around the world. Kloster’s vanity website and LinkedIn page both list him as CEO of a company called “**SL MobPartners**.”

In 2016, Deniskloster.com featured a post celebrating three years in operation. The anniversary post said Kloster’s anonymity business had grown to nearly two dozen employees, most of whom were included in a group photo posted to that article (and some of whom Kloster thanked by their first names and last initials).

The employees who kept things running for RSOCKS, circa 2016.

“Thanks to you, we are now developing in the field of information security and anonymity!,” the post enthuses. “We make products that are used by thousands of people around the world, and this is very cool! And this is just the beginning!!! We don’t just work together and we’re not just friends, we’re Family.”

Mr. Kloster did not respond to repeated requests for comment.

It’s not clear if the coordinated takedown targeting the RSOCKS botnet will be permanent, as the botnet’s owners could simply rebuild — and possibly rebrand — their crime machine. Based on the RSOCKS owner’s posts, that is exactly what they intend to do.

“RSocks ceases to exist,” wrote the Rsocks account on the BlackHatWorld forum on June 17. “But don’t worry. All the active plans and fund balances will be transferred to another service. Stay tuned. We will inform you about its name and all the details later.”

Rsocks told the BlackHatWorld community they would be back soon under a new name.

Malware-based proxy services like RSOCKS have struggled to remain competitive in a cybercrime market with increasingly sophisticated proxy services that offer many additional features. The demise of RSOCKS follows closely on the heels of **VIP72\[.\]com**, a competing proxy botnet service that operated for a decade before its owners pulled the plug on the service last year.

The Computer Emergency Response Team of Ukraine (CERT-UA) has cautioned of a new set of spear-phishing attacks exploiting the "Follina" flaw in the Windows operating system to deploy password-stealing malware.
Attributing the intrusions to a Russian nation-state group tracked as APT28 (aka Fancy Bear or Sofacy), the agency said the attacks commence with a lure document titled "Nuclear Terrorism

The Computer Emergency Response Team of Ukraine (CERT-UA) has cautioned of a new set of spear-phishing attacks exploiting the "Follina" flaw in the Windows operating system to deploy password-stealing malware.

Attributing the intrusions to a Russian nation-state group tracked as APT28 (aka Fancy Bear or Sofacy), the agency said the attacks commence with a lure document titled "Nuclear Terrorism A Very Real Threat.rtf" that, when opened, exploits the recently disclosed vulnerability to download and execute a malware called CredoMap.

Follina (CVE-2022-30190, CVSS score: 7.8), which concerns a case of remote code execution affecting the Windows Support Diagnostic Tool (MSDT), was addressed by Microsoft on June 14, 2022, as part of its Patch Tuesday updates.

According to an independent report published by Malwarebytes, CredoMap is a variant of the .NET-based credential stealer that Google Threat Analysis Group divulged last month as having been deployed against users in Ukraine.

The malware's main purpose is to siphon data, including passwords and saved cookies, from several popular browsers such as Google Chrome, Microsoft Edge, and Mozilla Firefox.

"Although ransacking browsers might look like petty theft, passwords are the key to accessing sensitive information and intelligence," Malwarebytes said. "The target, and the involvement of APT28, a division of Russian military intelligence), suggests that campaign is a part of the conflict in Ukraine, or at the very least linked to the foreign policy and military objectives of the Russian state."

It's not just APT28. CERT-UA has further warned of similar attacks mounted by Sandworm and an actor dubbed UAC-0098 that leverage a Follina-based infection chain to deploy CrescentImp and Cobalt Strike Beacons on to targeted hosts.

The development comes as Ukraine continues to be a target for cyberattacks amidst the country's ongoing war with Russia, with Armageddon hackers also spotted distributing the GammaLoad.PS1\_v2 malware in May 2022.

Russian Hackers Exploiting Microsoft Follina Vulnerability Against Ukraine

Data Processing and Infrastructure Processing Units – DPU and IPU – are changing the way enterprises deploy and manage compute resources across their networks.

SAN FRANCISCO, June 21, 2022 /PRNewswire/ -- The Linux Foundation, the nonprofit organization enabling mass innovation through open source, today announced the new Open Programmable Infrastructure (OPI) Project. OPI will foster a community-driven, standards-based open ecosystem for next-generation architectures and frameworks based on DPU and IPU technologies. OPI is designed to facilitate the simplification of network, storage and security APIs within applications to enable more portable and performant applications in the cloud and datacenter across DevOps, SecOps and NetOps.

Founding members of OPI include Dell Technologies, F5, Intel, Keysight Technologies, Marvell, NVIDIA and Red Hat with a growing number of contributors representing a broad range of leading companies in their fields ranging from silicon and device manufactures, ISVs, test and measurement partners, OEMs to end users.

"When new technologies emerge, there is so much opportunity for both technical and business innovation but barriers often include a lack of open standards and a thriving community to support them," said Mike Dolan, senior vice president of Projects at the Linux Foundation. "DPUs and IPUs are great examples of some of the most promising technologies emerging today for cloud and datacenter, and OPI is poised to accelerate adoption and opportunity by supporting an ecosystem for DPU and IPU technologies."

DPUs and IPUs are increasingly being used to support high-speed network capabilities and packet processing for applications like 5G, AI/ML, Web3, crypto and more because of their flexibility in managing resources across networking, compute, security and storage domains. Instead of the servers being the infrastructure unit for cloud, edge or the data center, operators can now create pools of disaggregated networking, compute and storage resources supported by DPUs, IPUs, GPUs, and CPUs to meet their customers' application workloads and scaling requirements.

OPI will help establish and nurture an open and creative software ecosystem for DPU and IPU-based infrastructures. As more DPUs and IPUs are offered by various vendors, the OPI Project seeks to help define the architecture and frameworks for the DPU and IPU software stacks that can be applied to any vendor's hardware offerings. The OPI Project also aims to foster a rich open source application ecosystem, leveraging existing open source projects, such as DPDK, SPDK, OvS, P4, etc., as appropriate. The project intends to:

*   Define DPU and IPU,
*   Delineate vendor-agnostic frameworks and architectures for DPU- and IPU-based software stacks applicable to any hardware solutions,
*   Enable the creation of a rich open source application ecosystem,
*   Integrate with existing open source projects aligned to the same vision such as the Linux kernel, and,
*   Create new APIs for interaction with, and between, the elements of the DPU and IPU ecosystem, including hardware, hosted applications, host node, and the remote provisioning and orchestration of software

With several working groups already active, the initial technology contributions will come in the form of the Infrastructure Programmer Development Kit (IPDK) that is now an official sub-project of OPI governed by the Linux Foundation. IPDK is an open source framework of drivers and APIs for infrastructure offload and management that runs on a CPU, IPU, DPU or switch. In addition, NVIDIA DOCA, an open source software development framework for NVIDIA's BlueField DPU, will be contributed to OPI to help developers create applications that can be offloaded, accelerated, and isolated across DPUs, IPUs, and other hardware platforms.

**_Geng Lin, EVP and Chief Technology Officer, F5  
_**"The emerging DPU market is a golden opportunity to reimagine how infrastructure services can be deployed and managed. With collective collaboration across many vendors representing both the silicon devices and the entire DPU software stack, an ecosystem is emerging that will provide a low friction customer experience and achieve portability of services across a DPU enabled infrastructure layer of next generation data centers, private clouds, and edge deployments."

**_Patricia Kummrow, CVP and GM, Ethernet Products Group, Intel  
_**Intel is committed to open software to advance collaborative and competitive ecosystems and is pleased to be a founding member of the Open Programmable Infrastructure project, as well as fully supportive of the Infrastructure Processor Development Kit (IPDK) as part of OPI. We look forward to advancing these tools, with the Linux Foundation, fulfilling the need for a programmable infrastructure across cloud, data center, communication and enterprise industries making it easier for developers to accelerate innovation and advance technological developments.

**_Ram Periakaruppan, VP and General Manager, Network Test and Security Solutions Group, Keysight Technologies  
_**"Programmable infrastructure built with DPUs/IPUs enables significant innovation for networking, security, storage and other areas in disaggregated cloud environments. As a founding member of the Open Programmable Infrastructure Project, we are committed to providing our test and validation expertise as we collaboratively develop and foster a standards-based open ecosystem that furthers infrastructure development, enabling cloud providers to maximize their investment."

**Cary Ussery, Vice President, Software and Support, Processors, Marvell  
**Data center operators across multiple industry segments are increasingly incorporating DPUs as an integral part of their infrastructure processing to offload complex workloads from general purpose to more robust compute platforms. Marvell strongly believes that software standardization in the ecosystem will significantly contribute to the success of workload acceleration solutions. As a founding member of the OPI Project, Marvell aims to address the need for standardization of software frameworks used in provisioning, lifecycle management, orchestration, virtualization and deployment of workloads.

**_Kevin Deierling, vice president of Networking at NVIDIA  
_**"The fundamental architecture of data centers is evolving to meet the demands of private and hyperscale clouds and AI, which require extreme performance enabled by DPUs such as the NVIDIA BlueField and open frameworks such as NVIDIA DOCA. These will support OPI to provide BlueField users with extreme acceleration, enabled by common, multi-vendor management and applications. NVIDIA is a founding member of the Linux Foundation's Open Programmable Infrastructure Project to continue pushing the boundaries of networking performance and accelerated data center infrastructure while championing open standards and ecosystems."

**_Erin Boyd, director of emerging technologies, Red Hat  
_**"As a founding member of the Open Programmable Infrastructure project, Red Hat is committed to helping promote, grow and collaborate on the emergent advantage that new hardware stacks can bring to the cloud-native community, and we believe that the formalization of OPI into the Linux Foundation is an important step toward achieving this in an open and transparent fashion. Establishing an open standards-based ecosystem will enable us to create fully programmable infrastructure, opening up new possibilities for better performance, consumption, and the ability to more easily manage unique hardware at scale."
