"Midnight Blizzard," a threat group linked to Russia's foreign intelligence service, is stoking more concern than usual for both its sheer scope and its use of a new tactic for harvesting information and gaining control of victim systems.

Microsoft this week said its threat intelligence group observed Midnight Blizzard actors sending out thousands of spear-phishing emails to targeted individuals at more than 100 organizations worldwide since Oct. 22.

**Large-Scale Campaign**

Besides its wide scope, the campaign is noteworthy for Midnight Blizzard's use of a digitally signed Remote Desktop Protocol (RDP) configuration file in its spear-phishing emails. The RDP file connects to a server controlled by a threat actor; when the file is opened, it allows the attacker to harvest user credentials and detailed system information to aid further exploit activity.

"The emails were highly targeted, using social engineering lures relating to Microsoft, Amazon Web Services (AWS), and the concept of zero trust," Microsoft said on its threat intelligence group blog this week. "Microsoft has observed this campaign targeting governmental agencies, higher education, defense, and non-governmental organizations in dozens of countries, but particularly in the UK, Europe, Australia, and Japan."

Midnight Blizzard — aka Cozy Bear, APT29, and UNC2452 — has been the proverbial thorn in the side of security organizations for some years now. The group's many victims include SolarWinds, Microsoft, HPE, multiple US federal government agencies, and diplomatic entities worldwide. Its well-documented tactics, techniques, and procedures (TTPs) include using spear phishing, stolen credentials, and supply chain attacks for initial access. Midnight Blizzard actors have also targeted vulnerabilities in widely used networking and collaboration technologies such as those from Fortinet, Pulse Secure, Citrix, and Zimbra to gain an initial toehold on a target network.

**Bidirectional Connection**

The RDP file in the Microsoft, AWS, and zero-trust themed emails in Midnight Blizzard's latest campaign allows the attacker to establish a quick, bidirectional connection with a compromised device. The threat actor is using it to harvest a range of information including user credentials, files, and directories on the victim system and connected network drives; information from connected smart cards and other peripherals; Web authentication credentials; and clipboard data. The RDF file is signed with a LetsEncrypt certificate to lend it an air of legitimacy. "This access could enable the threat actor to install malware on the target's local drive(s) and mapped network share(s), particularly in AutoStart folders, or install additional tools such as remote access Trojans (RATs) to maintain access when the RDP session is closed," Microsoft cautioned.

Stephen Kowski, field CTO at SlashNext, says Midnight Blizzard's use of signed RDP files in its current campaign is significant. Signed RDP files can bypass traditional security controls since they appear to come from a legitimate source, he points out.

"This technique is particularly cunning because RDP files are commonly used in business environments, making them less likely to raise immediate suspicion, while the legitimate signature helps evade standard malware detection systems," he says. He advocates that organizations scan all email attachments in real time, with a particular focus on RDP files and other seemingly legitimate Microsoft-related content. "The use of legitimately signed files creates a significant blind spot for conventional security tools that rely heavily on signature-based detection or reputation scoring," Kowski advises.

**Mitigating the Threat**

Microsoft has released a list of indicators of compromise for the new Midnight Blizzard campaign, including email sender domains, RDP files, and RDP remote computer domains. It has recommended that security teams review their organizational email security settings and antivirus and anti-phishing measures; turn on Safe Links and Safe Attachments settings in Office 365; and enable measures for quarantining sent email if needed. Other recommendations include using firewalls to block RDP connections, implementing multifactor authentication, and strengthening endpoint security configurations.

Venky Raju, field CTO at ColorTokens, says the campaign is a reminder why organizations need to maintain a tight rein over the use of Microsoft's remote desktop. While it can be useful to share devices, folders, and clipboard content over an RDP session, it gives attackers a way into a user's device. "Signing the RDP configuration file may prevent email security systems from classifying the email as having a suspicious link or attachment. It may also reduce the warnings presented by the RDP client," he points out.

'Midnight Blizzard' Targets Networks With Signed RDP Files

A deserialization vulnerability in the component \controller\Index.php of Thinkphp v6.1.3 to v8.0.4 allows attackers to execute arbitrary code.

**Exploitability Metrics**

Attack Vector: This metric reflects the context by which vulnerability exploitation is possible. This metric value (and consequently the resulting severity) will be larger the more remote (logically, and physically) an attacker can be in order to exploit the vulnerable system. The assumption is that the number of potential attackers for a vulnerability that could be exploited from across a network is larger than the number of potential attackers that could exploit a vulnerability requiring physical access to a device, and therefore warrants a greater severity.

Attack Complexity: This metric captures measurable actions that must be taken by the attacker to actively evade or circumvent existing built-in security-enhancing conditions in order to obtain a working exploit. These are conditions whose primary purpose is to increase security and/or increase exploit engineering complexity. A vulnerability exploitable without a target-specific variable has a lower complexity than a vulnerability that would require non-trivial customization. This metric is meant to capture security mechanisms utilized by the vulnerable system.

Attack Requirements: This metric captures the prerequisite deployment and execution conditions or variables of the vulnerable system that enable the attack. These differ from security-enhancing techniques/technologies (ref Attack Complexity) as the primary purpose of these conditions is not to explicitly mitigate attacks, but rather, emerge naturally as a consequence of the deployment and execution of the vulnerable system.

Privileges Required: This metric describes the level of privileges an attacker must possess prior to successfully exploiting the vulnerability. The method by which the attacker obtains privileged credentials prior to the attack (e.g., free trial accounts), is outside the scope of this metric. Generally, self-service provisioned accounts do not constitute a privilege requirement if the attacker can grant themselves privileges as part of the attack.

User interaction: This metric captures the requirement for a human user, other than the attacker, to participate in the successful compromise of the vulnerable system. This metric determines whether the vulnerability can be exploited solely at the will of the attacker, or whether a separate user (or user-initiated process) must participate in some manner.

**Vulnerable System Impact Metrics**

Confidentiality: This metric measures the impact to the confidentiality of the information managed by the VULNERABLE SYSTEM due to a successfully exploited vulnerability. Confidentiality refers to limiting information access and disclosure to only authorized users, as well as preventing access by, or disclosure to, unauthorized ones.

Integrity: This metric measures the impact to integrity of a successfully exploited vulnerability. Integrity refers to the trustworthiness and veracity of information. Integrity of the VULNERABLE SYSTEM is impacted when an attacker makes unauthorized modification of system data. Integrity is also impacted when a system user can repudiate critical actions taken in the context of the system (e.g. due to insufficient logging).

Availability: This metric measures the impact to the availability of the VULNERABLE SYSTEM resulting from a successfully exploited vulnerability. While the Confidentiality and Integrity impact metrics apply to the loss of confidentiality or integrity of data (e.g., information, files) used by the system, this metric refers to the loss of availability of the impacted system itself, such as a networked service (e.g., web, database, email). Since availability refers to the accessibility of information resources, attacks that consume network bandwidth, processor cycles, or disk space all impact the availability of a system.

**Subsequent System Impact Metrics**

Confidentiality: This metric measures the impact to the confidentiality of the information managed by the SUBSEQUENT SYSTEM due to a successfully exploited vulnerability. Confidentiality refers to limiting information access and disclosure to only authorized users, as well as preventing access by, or disclosure to, unauthorized ones.

Integrity: This metric measures the impact to integrity of a successfully exploited vulnerability. Integrity refers to the trustworthiness and veracity of information. Integrity of the SUBSEQUENT SYSTEM is impacted when an attacker makes unauthorized modification of system data. Integrity is also impacted when a system user can repudiate critical actions taken in the context of the system (e.g. due to insufficient logging).

Availability: This metric measures the impact to the availability of the SUBSEQUENT SYSTEM resulting from a successfully exploited vulnerability. While the Confidentiality and Integrity impact metrics apply to the loss of confidentiality or integrity of data (e.g., information, files) used by the system, this metric refers to the loss of availability of the impacted system itself, such as a networked service (e.g., web, database, email). Since availability refers to the accessibility of information resources, attacks that consume network bandwidth, processor cycles, or disk space all impact the availability of a system.

GHSA-pjhx-j53p-c5f5: ThinkPHP deserialization vulnerability

A malvertising campaign is exploiting Meta’s platform to spread SYS01 infostealer, targeting men 45+ via fake ads for…

A malvertising campaign is exploiting Meta’s platform to spread SYS01 infostealer, targeting men 45+ via fake ads for popular software. The malware steals Facebook credentials, hijacks accounts espicially those administrating business pages, and spreads further attacks globally.

A new malvertising campaign is exploiting Meta’s advertising platform to spread the **SYS01 infostealer**, a cybersecurity threat known to Meta and particularly Facebook users for stealing their personal information.

What makes this attack targeted is that millions of users globally, specifically men aged 45 and above, are potential victims of this ongoing attack, which cleverly disguises itself as advertisements for popular software, games, and online services.

This campaign, first detected in September 2024, stands out due to its impersonation tactics and popular brands that it exploits. Instead of focusing on a single lure, the attackers mimic a broad range of trusted brands, including productivity tools like Office 365, creative software like Canva and Adobe Photoshop, VPN services like ExpressVPN, streaming platforms like Netflix, messaging apps like Telegram, and even popular video games like Super Mario Bros Wonder.

****How the Attack Works:****

According to Bitdefender’s **blog post** shared with Hackread.com ahead of publishing on Wednesday, the malicious ads often lead to MediaFire links offering direct downloads of seemingly legitimate software. These downloads, packaged as zip archives, contain a malicious Electron application.

Once executed, this application drops and **runs the SYS01 infostealer**, often while displaying a decoy app that mimics the advertised software. This deceptive tactic makes it difficult for victims to realize they’ve been compromised.

For your information, an Electron application is a type of desktop app built with web technologies like HTML, CSS, and JavaScript. Electron is an open-source framework developed by GitHub that allows developers to create cross-platform applications that run on Windows, macOS, and Linux, all from a single codebase.

In this attack however, behind the scenes, the Electron app uses obfuscated Javascript code and a standalone 7zip executable to extract a password-protected archive containing the core malware components. This archive includes PHP scripts responsible for **installing the infostealer** and establishing persistence on the victim’s system. The malware also incorporates anti-sandbox checks to evade detection by security researchers.

****Stealing Data and Hijacking Accounts:****

The primary goal of the SYS01 infostealer is to harvest Facebook credentials, particularly those associated with business accounts. These compromised accounts are then used to further attacks/scams.

What’s worse, the attack also leverages the advertising capabilities of hijacked accounts, allowing attackers to create **new malicious ads** that appear more legitimate and easily bypass security filters. This creates a self-sustaining cycle where stolen accounts are used to spread the malware even further. The stolen credentials are also likely sold on underground marketplaces, further enriching the criminals.

****Global Reach and Protection****

While the campaign has a global reach, impacting users in the EU, North America, Australia, and Asia, Bitdefender could not verify the full extent of its impact, especially outside the EU, which remains unclear due to limited data transparency.

Nevertheless, if you are on Facebook—especially if you run a business page—you must watch out for SYS01 Infostealer and **similar threats**. While using common sense is essential, here are some vital steps you should take:

1.  **Monitor your accounts:** Regularly check your Facebook and other social media accounts for suspicious activity. Report any unauthorized access immediately and change your passwords.
2.  **Be wary of ads:** Exercise caution when clicking on ads, especially those offering free downloads or deals that seem too good to be true. Verify the source before downloading any software.
3.  **Stick to official sources:** Download software directly from official websites or trusted app stores. Avoid third-party platforms and file-sharing services.
4.  **Use strong security software:** Install reputable security software and keep it updated. Choose a solution that offers real-time protection and advanced threat detection.
5.  **Enable two-factor authentication (2FA):** Activate 2FA on your Facebook and other important online accounts for added security.

PRESS RELEASE

TEMPE, Ariz. and PRAGUE, Oct. 29, 2024 /PRNewswire/ -- Holiday shopping is in full swing, with over 60% of Americans ready to click "add to cart" for most of their purchases this holiday season. But it's not just shoppers gearing up – scammers are, too. Nearly half (48%) of U.S. consumers report being targeted by a scam while holiday shopping online, according to the 2024 Norton Cyber Safety Insights Report: Holiday. Additionally, more than half (53%) of Americans are worried about Black Friday and Cyber Monday shopping scams. Norton, a consumer Cyber Safety brand of Gen (NASDAQ: GEN), encourages people to take time on Cyber Safety Sunday, December 1st, to prepare to safely shop online this holiday season and bolster their defenses against cybercriminals and scammers.

'Tis the Season for Shopping and Scamming

Cyber Safety Sunday is observed the Sunday after Thanksgiving and is a day for shoppers to take proactive steps to prioritize their online safety ahead of shopping Cyber Week deals, booking holiday travel, and more. Nearly half of Americans (48%) will do most of their holiday shopping between Black Friday and Cyber Monday – making it not only the busiest time of the year for shoppers – but also scammers. Thirty percent of Americans say they have been targeted by a scam while holiday shopping online. Of the two fifths (43%) who fell victim, 30% report the scam happened on Black Friday, 11% on Cyber Monday and 30% on Christmas.

"The holidays can be a hectic time, and when we are busy or looking for ways to save money, sometimes we let our guard down," said Leyla Bilge for Norton. "This Cyber Safety Sunday, we encourage everyone to take a few simple steps that will go a long way to help you stay safe online this season. Stick to sites you trust, stay educated on common scams, update passwords, set fraud alerts and always think twice before sharing your personal information. Give yourself the gift of peace of mind knowing you're prepared."

Rising Concerns Over Cyber Grinches 

Of the 90% of Americans buying gifts to spread holiday cheer, 60% will be clicking "add to cart" for most of their presents this season. While online shopping is fun and convenient, the rise in online crime has made shoppers feel less merry and more wary about their online safety. In fact, 62% are concerned about becoming victims of cybercrime this season, with 47% specifically worried about falling for a sophisticated holiday shopping scam. A look deeper into Norton's data reveals concerns rising from last year:

*   71% of US consumers are concerned about their personal details being compromised, up 8% YoY. 
    
*   59% are concerned about being scammed by a 3rd party retailer, up 9% YoY. 
    
*   59% are concerned about AI shopping scams, up 11% YoY. 
    

Decking the Halls with Discounts 

With the costs of many goods on the rise, everyone's looking to stretch their holiday budgets a little further, resulting in 87% of U.S. online shoppers spending extra time to look for discount codes. However, it is important to be aware of the information you offer to gain access to these deals, as it can lead to significant privacy risks.  When you enter personal details, such as your name, email or payment information to redeem a discount code, that data could fall into the wrong hands if the website is not secure. Some scammers also create fake promotions or clone legitimate retailer websites to trick consumers into submitting their information, which they can then use for identity theft, financial fraud or to sell on the dark web.

Norton discovered that two thirds (67%) of people have taken some action to receive a discount code. Of these deal seekers, 57% signed up for a mailing list, 39% answered a survey and 30% liked a post or posted on social media. Nearly two-thirds (65%) of people were willing to give personal information including their email (91%), phone number (52%) or home address (35%).

It's no coincidence that while shoppers are keen for discounts, malvertising and adware are the cyber threats that increase the most dramatically during the holiday season. During last year's holiday shopping season, Gen data reveals a 53% increase in malvertising attacks – malicious ads often seen by consumers when searching for something such as sales. Adware – malicious software often distributed via malvertising – increased by 227% over the same period.

To stay safe, try to find codes directly from the retailer and not third-party providers. Consider using an alternative email address that you don't typically use for daily, personal life. Products such as Norton AntiTrack can create these emails for you in a single click. Think twice: Is the discount worth potentially compromising your digital safety or identity?

Enlisting AI Holiday Helpers 

Both retailers and consumers are using AI tools to help ease the stress of holiday shopping. Nearly a quarter of people (23%) have interacted with an AI chatbot or assistant and 43% have noticed AI-enhanced search results with personal recommendations while shopping.

While 36% of Americans say that AI recommendations are helpful and could enhance their online shopping experience, most shoppers are still resistant to AI. Fifty-seven percent of people say they would abandon their carts if they could only speak with a chatbot rather than a real customer service representative. Only 26% of shoppers trust AI to handle their personal information securely, and 37% who have interacted with an AI chatbot while holiday shopping online report receiving inaccurate information.

Sleighing Suspicious Social Media Ads 

Despite general distrust in social media sites, shoppers continue to click on social ads to purchase holiday gifts. Thirty-seven percent of Americans have purchased a holiday gift from a social ad, with these buyers mainly purchasing through Facebook (60%), Instagram (48%) and TikTok (40%).

Clicking on social media ads can expose people to unnecessary risks such as phishing attacks, malware infections and privacy breaches. Fraudulent ads may lead to fake websites that steal personal information or payment details, and some may download harmful or malicious software onto your device. Despite these risks, 20% of people are still willing to click on a social media ad or email claiming to offer a gift—reminding us all that some "holiday deals" belong on the naughty list.

This Cyber Safety Sunday, take control of your Cyber Safety by using AI to spot scams. Norton Genie is an AI-powered app that provides a fast, easy and free way to check if a message, like an email offering a holiday discount, is a scam. Genie can also review social media links and other suspicious web links, such as those that direct people to track deliveries for holiday gifts, offer gift cards or steer people to fake third-party websites and confirm whether the information or offer is malicious.

PRESS RELEASE

RALEIGH, N.C., Oct. 28, 2024 /PRNewswire-PRWeb/ -- ALL THINGS OPEN 2024 -- After a year-long, global, community design process, the Open Source Definition (OSAID) v.1.0 is available for public use.

The release of version 1.0 was announced today at All Things Open 2024, an industry conference focused on common issues of interest to the worldwide Open Source community. The OSAID offers a standard by which community-led, open and public evaluations will be conducted to validate whether or not an AI system can be deemed Open Source AI. This first stable version of the OSAID is the result of multiple years of research and collaboration, an international roadshow of workshops, and a year-long co-design process led by the Open Source Initiative (OSI), globally recognized by individuals, companies and public institutions as the authority that defines Open Source.

"The co-design process that led to version 1.0 of the Open Source AI Definition was well-developed, thorough, inclusive and fair," said Carlo Piana, OSI board chair. "It adhered to the principles laid out by the board, and the OSI leadership and staff followed our directives faithfully. The board is confident that the process has resulted in a definition that meets the standards of Open Source as defined in the Open Source Definition and the Four Essential Freedoms, and we're energized about how this definition positions OSI to facilitate meaningful and practical Open Source guidance for the entire industry."

"The new definition requires Open Source models to provide enough information about their training data so that a 'skilled person can recreate a substantially equivalent system using the same or similar data,' which goes further than what many proprietary or ostensibly Open Source models do today," said Ayah Bdeir, who leads AI strategy at Mozilla. "This is the starting point to addressing the complexities of how AI training data should be treated, acknowledging the challenges of sharing full datasets while working to make open datasets a more commonplace part of the AI ecosystem. This view of AI training data in Open Source AI may not be a perfect place to be, but insisting on an ideologically pristine kind of gold standard that will not actually be met by any model builder could end up backfiring."

"We welcome OSI's stewardship of the complex process of defining Open Source AI," said Liv Marte Nordhaug, CEO of the Digital Public Goods Alliance (DPGA) secretariat. "The Digital Public Goods Alliance secretariat will build on this foundational work as we update the DPG Standard as it relates to AI as a category of DPGs."

"Transparency is at the core of EleutherAI's non-profit mission. The Open Source AI Definition is a necessary step towards promoting the benefits of Open Source principles in the field of AI," said Stella Biderman, executive director at the EleutherAI Institute. "We believe that this definition supports the needs of independent machine learning researchers and promotes greater transparency among the largest AI developers."

"Arriving at today's OSAID version 1.0 was a difficult journey, filled with new challenges for the OSI community," said OSI Executive Director, Stefano Maffulli. "Despite this delicate process, filled with differing opinions and uncharted technical frontiers—and the occasional heated exchange—the results are aligned with the expectations set out at the start of this two-year process. This is a starting point for a continued effort to engage with the communities to improve the definition over time as we develop with the broader Open Source community the knowledge to read and apply OSAID v.1.0."

PRESS RELEASE

LONDON, Oct. 28, 2024 /PRNewswire/ -- VIPRE Security Group, a global leader and award-winning cybersecurity, privacy, and data protection company, has released its Q3 2024 Email Threat Trends Report, shedding light on the evolving cybersecurity landscape. This comprehensive analysis of real-world data reveals the sophisticated strategies and techniques employed by cybercriminals, with a particular persistent focus on the highly lucrative tactic of business email compromise (BEC). VIPRE processed 1.8 billion emails globally, of which 208 million were malicious.

BEC impersonation weaponisation  

In this third quarter of 2024, cybercriminals intensified their efforts to exploit organisational vulnerabilities through employee deception. BEC scams surged, accounting for 58% of phishing attempts. Notably, 89% of these BEC attacks involved impersonation of authority figures, including CEOs, senior executives, and IT staff, underscoring the sophisticated tactics employed by malicious actors.

BEC aims for the manufacturing sector 

The manufacturing sector saw a significant rise in BEC attacks, potentially driven by financial fraud. These incidents increased from just 2% in Q1 to 10% in Q3 this year. This rise may be attributed to the industry's widespread use of mobile sign-ins at various worksites. Employees accessing systems "on the go", often under pressure to meet production deadlines, are more susceptible to phishing attempts.

Subtler tactics are a larger threat

Email threats in Q3 were dominated by scams (34%), commercial spam (30%), and phishing (20%). These email threats overshadowed ransomware and malware combined, which comprised less than 20% of all email attacks. Interestingly, despite their lower prevalence, ransomware and malware continue to receive disproportionate attention from the cybersecurity industry.

Sneakier attachments 

To counter advancing email security solutions, criminals are deploying increasingly more intricate methods to bypass defenses. Attackers are employing sneakier techniques such as disguising malicious attachments as voicemail recordings or critical security updates to lure unsuspecting users into downloading them.

Additionally, Microsoft PDFs and .DOCX files remain the most common forms of malicious attachments. In Q3 2024, 2.18 million emails were detected containing harmful attachments, marking a 30% increase from the previous quarter's 21% attachment-based attacks.

Phishing links and compromised websites

Cybercriminals continue to favour the URL redirection technique, a tactic that typically proves effective at evading security controls. This deceptive ploy utilises a "clean" URL within the body of the email, which then redirects unsuspecting users to a malicious one once inside. In Q3 2024, URL redirection accounted for 52% of such attacks, leading victims to meticulously crafted fraudulent websites designed to appear authentic, and gain trust.

Malspam pendulum swing from malicious links to attachments

When it comes to malspam, there is a pendulum swing from a preference for malicious links to attachments. During Q3, malspam efforts were centered on malicious attachments (64%), while only 36% employed a link. The attachment formats used were predominantly LNK, ZIP, and DOCX. Only a quarter ago, links were the tool of choice by a factor of nearly nine-to-one (86% links to 14%).

The 'Malware Family of the Quarter' goes to Redline

Redline is the top malspam family of Q3 2024, a spot it has maintained since the corresponding quarter in 2023. RedLine is designed to steal sensitive information from web browsers, such as credentials and payment data. Typically distributed via phishing emails or malicious websites, it sends stolen data to a command-and-control server controlled by the attacker. It can completely take over a compromised machine and uses multiple infiltration methods.

"The findings of this report yet again illustrate the sophistication of criminal tactics. BEC email and phishing attacks are becoming more targeted and convincing," Usman Choudhary, CPTO, VIPRE Security Group, says. "Additionally, malware distribution through malicious spam campaigns continues to pose a serious threat to organisations. These findings stress the critical need for robust cybersecurity measures and ongoing employee education to combat these evolving threats, especially as bad actors gear up for the upcoming holiday season – Black Friday, Thanksgiving, Christmas, and New Year."

Russian state-sponsored hackers Cozy Bear are targeting over 100 organizations globally with a new phishing campaign. This sophisticated attack uses signed RDP files disguised as legitimate documents to gain remote access and steal sensitive data. Learn how to protect yourself and your organization from this threat.

Microsoft has revealed that the Russian state-sponsored threat actor Cozy Bear (or APT29, UNC2452, and Midnight Blizzard) has launched a new phishing campaign targeting over 100 organizations worldwide, especially Ukraine, the United States and Europe.

The campaign, active since October 22, 2024, involves highly targeted emails designed to trick users into opening malicious files, ultimately granting the attackers access to sensitive information.

The attackers are mainly focusing on organizations in critical sectors such as government, defence, academia, and non-governmental organizations. This aligns with Cozy Bear’s previous pattern of targeting entities holding valuable intelligence.

****What’s new this time?****

Cozy Bear is using a never-before-seen approach involving signed Remote Desktop Protocol (RDP) configuration files. These apparently harmless files are sent as attachments in phishing emails, often disguised with lures related to Microsoft, Amazon Web Services (AWS), and the concept of Zero Trust. The emails are composed with sophistication, even impersonating Microsoft employees to enhance their credibility.

****How does it work?****

According to Microsoft’s blog post shared with Hackread.com ahead of publishing, when a user opens the malicious RDP file, a connection is established to a server controlled by Cozy Bear.

This connection grants the attackers access to a wide range of resources on the victim’s device, including files, connected peripherals, clipboard data, and even authentication features. This access can be exploited to install malware, steal sensitive data, and maintain persistent access even after the RDP session is closed.

****What’s at risk?****

The potential consequences of a successful attack are significant. Cozy Bear could gain access to confidential government information, intellectual property, and sensitive data belonging to various organizations. The compromised devices could also be used as launchpads for further attacks, potentially spreading the infection to other connected systems.

Patrick Harr, CEO of Pleasanton, Calif.-based SlashNext Email Security+, commented on the recent developments, warning organizations about the increasing sophistication of phishing attacks.

_“_This attack once again highlights that phishing continues to be the most dangerous threat to your organization which is why companies must not only continuously train their users, they must also employ AI detection and phishing sandboxes for malicious links and files directly in their email, collaboration and messaging apps,_“_ Patrick advised.

_“_These new sophisticated attacks, many of them AI-generated, evade current secure email gateways (SEGs) and even Microsoft Defender for Office. The only way organizations can defend themselves is by using AI to prevent these attacks before successful breaches._“_

Microsoft, along with CERT-UA and Amazon, has confirmed the ongoing campaign and is working to notify affected customers. Cybersecurity experts urge organizations and individuals to be alert, especially when dealing with emails containing attachments or requests for remote access.

Additionally, enabling multi-factor authentication, using phishing-resistant authentication methods, and educating users about these phishing techniques are important steps in mitigating this attack.

Ransomware / Threat Intelligence

Threat actors in North Korea have been implicated in a recent incident that deployed a known ransomware family called Play, underscoring their financial motivations.

The activity, observed between May and September 2024, has been attributed to a threat actor tracked as **Jumpy Pisces**, which is also known as Andariel, APT45, DarkSeoul, Nickel Hyatt, Onyx Sleet (formerly Plutonium), Operation Troy, Silent Chollima, and Stonefly.

"We believe with moderate confidence that Jumpy Pisces, or a faction of the group, is now collaborating with the Play ransomware group," Palo Alto Networks Unit 42 said in a new report published today.

"This incident is significant because it marks the first recorded collaboration between the Jumpy Pisces North Korean state-sponsored group and an underground ransomware network."

Andariel, active since at least 2009, is affiliated with North Korea's Reconnaissance General Bureau (RGB). It has been previously observed deploying two other ransomware strains known as SHATTEREDGLASS and Maui.

Earlier this month, Symantec, part of Broadcom, noted that three different organizations in the U.S. were targeted by the state-sponsored hacking crew in August 2024 as part of a likely financially motivated attack, even though no ransomware was deployed on their networks.

Play, on the other hand, is a ransomware operation that's believed to have impacted approximately 300 organizations as of October 2023. It is also known as Balloonfly, Fiddling Scorpius, and PlayCrypt.

While cybersecurity firm Adlumin revealed late last year that the operation may have transitioned to a ransomware-as-a-service (RaaS) model, the threat actors behind Play have since announced on their dark web data leak site that it's not the case.

In the incident investigated by Unit 42, Andariel is believed to gained initial access via a compromised user account in May 2024, followed by undertaking lateral movement and persistence activities using the Sliver command-and-control (C2) framework and a bespoke backdoor called Dtrack (aka Valefor and Preft).

"These remote tools continued to communicate with their command-and-control (C2) server until early September," Unit 42 said. "This ultimately led to the deployment of Play ransomware."

The Play ransomware deployment was preceded by an unidentified threat actor infiltrating the network using the same compromised user account, after which they were observed carrying out credential harvesting, privilege escalation, and uninstallation of endpoint detection and response (EDR) sensors, all hallmarks of pre-ransomware activities.

Also utilized as part of the attack was a trojanized binary that's capable of harvesting web browser history, auto-fill information, and credit card details for Google Chrome, Microsoft Edge, and Brave.

The use of the compromised user account by both Andariel and Play Asia, the connection between the two intrusion sets stems from the fact that communication with the Sliver C2 server (172.96.137\[.\]224) remained ongoing until the day before ransomware deployment. The C2 IP address has been offline since the day the deployment took place.

"It remains unclear whether Jumpy Pisces has officially become an affiliate for Play ransomware or if they acted as an IAB \[initial access broker\] by selling network access to Play ransomware actors," Unit 42 concluded. "If Play ransomware does not provide a RaaS ecosystem as it claims, Jumpy Pisces might only have acted as an IAB."
