Polish authorities and FortiGuard Labs have issued a warning to customers about a new wave of cyberattacks associated with TeamCity.
This is a post from HackRead.com Read the original post: Russian APT29 Hacked US Biomedical Giant in TeamCity-Linked Breach

According to cybersecurity researchers at FortiGuard Labs, the Russian intelligence-linked APT29 group exploited a critical TeamCity vulnerability, which had initially been patched in September 2023.

Polish Military Counterintelligence Service (SKW) has released an advisory revealing that Russian Foreign Intelligence Service (SVR) affiliated threat actors are utilizing JetBrains CVE in global targeting. 

Here, it is worth noting that TeamCity and JetBrains are closely linked, with TeamCity being a continuous integration (CI) server developed and maintained by JetBrains.

As **reported by Hackread**.com, the vulnerability, which scored 9.8 by CVSS, was patched in September 2023. However, authorities particularly identified the notorious advanced persistent threat group called APT29, aka the Dukes, CozyBear, and NOBELIUM/Midnight Blizzard, to be exploiting CVE-2023-42793.

The threat actor used Scheduled Tasks to execute GraphicalProton payloads, using rundll32 proxy execution as a defence evasion method. They also used legitimate third-party binaries vulnerable to search order hijacking.

“If compromised, access to a TeamCity server would provide malicious actors with access to that software developer’s source code, signing certificates, and the ability to subvert software compilation and deployment processes—access a malicious actor could further use to conduct supply chain operations” the **advisory** read.

SKW’s findings are supported by the FortiGuard Labs team of researchers. In their latest **blog post**, FortiGuard reports that APT29 has targeted a US-based biomedical manufacturing organization (_the name of which has not been shared with the media or public_) and revealed the threat actor’s TTPs. The report discusses the intrusion of this vulnerability found in TeamCity, a Windows server, by **APT29**.

Researchers noted that on 6 September 2023, Sonar’s cybersecurity experts discovered a critical TeamCity On-Premises vulnerability (tracked as **CVE-2023-42793**). This vulnerability was assigned a CVSS score of 9.8 due to its ability to be deployed without authentication. CISA added it to its ‘Known Exploited Vulnerabilities Catalog’ on October 4, 2023.

The FortiGuard Incident Response team reports that in October 2023, a US-based biomedical manufacturing organization was compromised due to this vulnerability exploited by APT29. The attack was initially exploited using a custom-built Python script, matching the GraphicalProton malware used by APT29. 

Analysis of application and system logs revealed evidence of successful exploitation, but some threat actors were unsuccessful at running **Linux system** commands on the victim Windows Server. APT29 likely employed Nuclei to identify potential victims and began executing additional discovery commands to gather system and privilege information.

The US-based tertiary education organization was targeted by APT29 with a C2 IP address discovered by the FortiGuard IR team. They discovered the organization’s infrastructure was compromised and identified an exploitation of their vulnerable TeamCity server. 

The threat actor used the TeamCity exploit to install an SSH certificate, which they used to maintain access to another victim’s environment. The actor downloaded a DLL file, ‘AclNumsInvertHost.dll,’ on the TeamCity host and used the TeamCity RCE vulnerability to create a Windows-scheduled task referencing the DLL file for persistence.

Despite a patch, the attacker persisted on the compromised host, leveraging their GraphicalProton implant. FortiGuard believes this attack was part of a **new APT29 campaign**. Significant OPSEC considerations included compromised infrastructure, search order hijacking with legitimate DLLs added, quality of masquerading, and single-use infrastructure components.

Researchers recommend containment and eradication actions, including blocking IP addresses, removing TeamCity software accounts, removing Windows accounts, removing backdoors, and removing malicious files dropped by threat actors to stay protected against threats like GraphicalProton.

Russian APT29 Hacked US Biomedical Giant in TeamCity-Linked Breach

Temporary data passed between application components by Budgie Extras Window Shuffler applet could potentially be viewed or manipulated. The data is stored in a location that is accessible to any user who has local access to the system. Attackers may pre-create and control this file to present false information to users or deny access to the application and panel.

**Impact**

Temporary data is written to a local locations accessible by all users for the host for the Budgie Extras WeatherShow applet.

The data file format is easily guessable; this potentially allows another user to present false information to the other user or could be used as an attack vector to deny access to the application through manipulation of files in this accessible file location.

Key issues:

1.  Data is monitored and can be displayed in the applet listbox. Ths can confuse a users GUI.
2.  Data can be manipulated by another user controlling whether to display or close a popup dialog. This can confuse a users GUI.
3.  By placing a FIFO the popup could be subject to denial-of-service  
    (either by blocking it indefinitely or by feeding it large amounts of  
    data, leading to an out-of-memory situation).

Without the Linux kernel's symlink protection it can be used to read from arbitrary files, or to operate in  
arbitrary directories.

4.  By placing a file in the host location, the existence check by the shuffler daemon will never trigger and thus any user rules will not run. This can confuse the users GUI.
    
5.  By placing a file is a known location this can control the display or closing of the shuffler grid-window and thereby confusing the Users GUI.
    
6.  The warning image is created programmatically.
    

A local attacker can attempt to place arbitrary PNG data in this path  
and have it displayed on the victim's desktop.

7.  Data in a file is evaluated; there is a chance for a local attacker to massively break the  
    layout logic or maybe even achieve code execution. The  
    Linux kernel's protected\_regular sysctl setting comes to the rescue  
    here, though. The open() with O_CREAT will fail. It can then  
    still present a denial-of-service vector, though.

**Patches**

The fix has been resolved in a patch release v1.7.1

**Workarounds**

This issue can be mitigated if there is only one user account on the system and limiting physical access to other users to the host system.

CVE-2023-49344: Potential leak of data captured and DoS potential attack for budgie-extras Window Shuffler application

A flaw was found in Keycloak that prevents certain schemes in redirects, but permits them if a wildcard is appended to the token. This issue could allow an attacker to submit a specially crafted request leading to cross-site scripting (XSS) or further attacks. This flaw is the result of an incomplete fix for CVE-2020-10748.

CVE-2023-6134

Everyone's New Year's Resolution should be to stop using passwords altogether.

Thursday, December 14, 2023 14:00

As you’ve probably seen by now, Talos released our 2023 Year in Review report last week. It’s an extremely comprehensive look at the top threats, attacker trends and malware families from the past year with never-before-seen Cisco Talos telemetry. 

We have podcasts, long-form videos and even Reddit AMAs to keep you covered and make it easy to digest our major takeaways from the report. Or, just kick back with a cup of coffee and read the full report — your choice! 

With this being the last Threat Source newsletter of the calendar year, I figured I’d do a Year in Review of my own. I don’t have the data or first-hand research to back any of these statements up, this is purely just _vibes_\-based or things I’ve discovered about myself and my cybersecurity habits over the past year, so while you may not be able to deploy any of these things on your firewall, I hope they serve as good advice to anyone thinking about the security landscape heading into the new year. 

*   **Do as I say, not as I do.** Before my daughter was born, I wrote in this newsletter about how I was skeptical about posting her face online and entering her personal data into various platforms while she’s so young and unable to even understand what a phone is. As soon as she was old enough to smile, I folded quickly. I’ll admit that I’ve posted her face all over Instagram, supplied her information to Gerber to enter her into the annual Gerber Baby competition (she came up short behind Maddie, apparently) and given personal information to who knows what sites while I was randomly trying to get answers to my first-time parent questions at 2 a.m. when she was getting her first tooth. None of these things are particularly smart in the long run, but as an unbiased observer, I can confidently say her cuteness on the internet only makes it a better place. 
*   **Just assume your passwords are going to get out there.** Several major password management services were hit with data breaches this year. And there were countless headlines about how brute-forcing password guesses led to others. The basic idea of a password manager is that your login information is inherently safer than just using the same password repeatedly, writing them down on a physical sheet of paper, or just hoping you remember each time you log in. At this point, I think it’s just safe to say that passwords are not your safest option. Passkeys and a passwordless approach to security are becoming increasingly popular, so where you can enroll in that, do it. Or if a traditional username and password combination is your only option, change that password as often as you can and make sure you have multi-factor authentication enabled to whatever password management service you use.  
*   **It’s time to get off Twitter.** Or X, whatever you want to call it. This platform has fully jumped the shark at this point and is rife with misinformation. The company has completely torn down any internal teams it has dedicated to fighting fake news or scams and searching for literally anything will surface misleading information, outright lies or offensive content. I miss the days when I could go to Twitter and search for a topic to get updates on a particular news item. I’m writing this on Dec. 13, and in the “Trending” sidebar on Twitter, I saw that “#cyberattack” was trending. Naturally, I wanted to see if there was an event going on I should be aware of, for obvious reasons. Instead, my results in the “Top” section included some word salad about the Bank of England targeting its own country’s critical infrastructure, a nonsensical clip from commentator Dan Bongino about woke leftists showing a cyber pandemic in a new movie, and a shocking amount of conspiracy theories about said new movie “Leave the World Behind.” It reminds me of the Michael Bluth line from “Arrested Development” when he grabs the bag out of the fridge that says, “Dead Dove DO NOT EAT.” 
*   **Don’t ever assume a threat is gone forever.** Over the past year, many major threat actors and malware operators that were once thought removed showed they could find a way back. The story of the FBI’s takedown of the Qakbot botnet was a major headline in August, and anyone who read the basic coverage would have thought, “Cool, don’t need to worry about those guys anymore!” However, subsequent research from Talos and other security firms found that remnants of Qakbot are still around, specifically services dedicated to sending spam. Trickbot, a major threat actor known for big game hunting, recently switched up its tactics and is actively targeting organizations in Ukraine, despite its developer being arrested and pleading guilty to several U.S. federal charges. And Emotet, which is known for its various stops-and-starts, is relatively quiet right now but was briefly active again earlier this year. This is not to say that these law enforcement server takedowns and arrests aren’t working — anything we can do to make the bad guys’ lives harder is a win in the end — but it’s continued proof that we can never really count any threat out.  

**The one big thing **

Cisco Talos recently discovered a new campaign conducted by the Lazarus Group we’re calling “Operation Blacksmith,” employing at least three new DLang-based malware families, two of which are remote access trojans (RATs), where one of these uses Telegram bots and channels as a medium of command and control (C2) communications. Our latest findings indicate a definitive shift in the tactics of the infamous North Korean state-sponsored actor. 

**Why do I care? **

This particular activity can be attributed to Andariel, a spinoff of the Lazarus Group. They’re actively exploiting the Log4shell vulnerability in Log4j, which is virtually everywhere. The hope is that most people have patched since the ubiquitous vulnerability was discovered in late 2021, but telemetry indicates there are many vulnerable instances still out there. Once infected, Andariel looks to install other malware loaders on the targeted machines and executes remote code that allows them to learn about the details of the system.  

**So now what? **

Talos’ blog outlines the numerous ways Cisco Secure products have protections in place to defend against Operation Blacksmith and other activities from Lazarus Group. 

**Top security headlines of the week **

**Hundreds of Windows and Linux devices from a range of manufacturers are vulnerable to a newly discovered attack called “LogoFAIL.”** The attack involves an adversary executing malicious firmware during the machines’ boot-up sequences, which means it’s difficult for traditional detection methods to block, or for users to even notice that it’s happening. The researchers who discovered this exploit wrote in their full paper that, once the attacker uses LogoFAIL to execute remote code during the Driver Execution Environment phase, it’s “game over for platform security.” Although there is no indication this type of attack has been used in the wild, it is being tracked through several CVEs. Potentially affected users should update to the latest version of UEFI by updating their firmware, including new patches from AMI, Intel, Insyde, Phoenix and Lenovo. Users can also lock down their machine’s EFI System Partition (ESP) so adversaries can’t access it, which is necessary to carry out LogoFAIL. (ArsTechnica, ZDNet) 

**The U.K. publicly charges Russia’s intelligence agency, the FSB, of a yearslong cyber espionage campaign targeting British government officials and other high-profile public citizens.** The U.K. Foreign Office said the FSB conducted "sustained unsuccessful attempts to interfere in U.K. political processes” over several years, including stealing information relating to the country’s national elections in 2019. The alleged campaigns involved trying to breach emails belonging to politicians, journalists, activists and academics, and fake social media profiles set up to impersonate the target’s contacts. One MP in British parliament said their emails had been stolen. Several individuals belonging to a group known as Star Blizzard have been sanctioned for their connections to these activities. (BBC, Politico) 

**Several major hardware and software vendors released their last patches of the calendar year this week.** Microsoft disclosed four critical vulnerabilities as part of its regular Patch Tuesday, three of which could lead to remote code execution. However, the total number of vulnerabilities included in December’s Patch Tuesday, 33, was the lowest in a single month since December 2019. Meanwhile on Monday, Apple released patches for its major pieces of hardware, disclosing security issues in iPhones, Macs and more. One of the vulnerabilities in macOS, CVE-2023-42914, is a kernel issue with the potential to allow apps to break out of their sandboxes. Additionally, the U.S. Cybersecurity and Infrastructure Security Agency released an advisory that attackers are actively exploiting a vulnerability in Adobe ColdFusion, which potentially poses a threat to government agencies. CVE-2023-26360 is an improper access control issue that could lead to arbitrary code execution. (Dark Reading, Talos, Security Boulevard)

A personal Year in Review to round out 2023

Cybersecurity researchers have identified a set of 116 malicious packages on the Python Package Index (PyPI) repository that are designed to infect Windows and Linux systems with a custom backdoor.

Malware / Supply Chain Attack

Cybersecurity researchers have identified a set of 116 malicious packages on the Python Package Index (PyPI) repository that are designed to infect Windows and Linux systems with a custom backdoor.

"In some cases, the final payload is a variant of the infamous W4SP Stealer, or a simple clipboard monitor to steal cryptocurrency, or both," ESET researchers Marc-Etienne M.Léveillé and Rene Holt said in a report published earlier this week.

The packages are estimated to have been downloaded over 10,000 times since May 2023.

The threat actors behind the activity have been observed using three techniques to bundle malicious code into Python packages, namely via a test.py script, embedding PowerShell in setup.py file, and incorporating it in obfuscated form in the \_\_init\_\_.py file.

Irrespective of the method used, the end goal of the campaign is to compromise the targeted host with malware, primarily a backdoor capable of remote command execution, data exfiltration, and taking screenshots. The backdoor module is implemented in Python for Windows and in Go for Linux.

Alternately, the attack chains also culminate in the deployment of W4SP Stealer or a clipper malware designed to keep close tabs on a victim's clipboard activity and swapping the original wallet address, if present, with an attacker-controlled address.

The development is the latest in a wave of compromised Python packages attackers have released to poison the open-source ecosystem and distribute a medley of malware for supply chain attacks.

It's also the newest addition to a steady stream of bogus PyPI packages that have acted as a stealthy channel for distributing stealer malware. In May 2023, ESET revealed another cluster of libraries that were engineered to propagate Sordeal Stealer, which borrows its features from W4SP Stealer.

Then, last month, malicious packages masquerading as seemingly innocuous obfuscation tools were found to deploy a stealer malware codenamed BlazeStealer.

"Python developers should thoroughly vet the code they download, especially checking for these techniques, before installing it on their systems," the researchers cautioned.

The disclosure also follows the discovery of npm packages that were found targeting an unnamed financial institution as part of an "advanced adversary simulation exercise." The names of the modules, which contained an encrypted blob, have been withheld to protect the identity of the organization.

"This decrypted payload contains an embedded binary that cleverly exfiltrates user credentials to a Microsoft Teams webhook that is internal to the target company in question," software supply chain security firm Phylum disclosed last week.
