The supply chain attack targeting 3CX was the result of a prior supply chain compromise associated with a different company, demonstrating a new level of sophistication with North Korean threat actors.

The supply chain attack targeting 3CX was the result of a prior supply chain compromise associated with a different company, demonstrating a new level of sophistication with North Korean threat actors.

Google-owned Mandiant, which is tracking the attack event under the moniker **UNC4736**, said the incident marks the first time it has seen a "software supply chain attack lead to another software supply chain attack."

The Matryoshka doll-style cascading attack against 3CX first came to light on March 29, 2023, when it emerged that Windows and macOS versions of its communication software were trojanized to deliver a C/C++-based data miner named ICONIC Stealer by means of a downloader, SUDDENICON, that used icon files hosted on GitHub to extract the server containing the stealer.

"The malicious application next attempts to steal sensitive information from the victim user's web browser," the U.S. Cybersecurity and Infrastructure Security Agency (CISA) said in an analysis of the malware. "Specifically it will target the Chrome, Edge, Brave, or Firefox browsers."

Select attacks targeting cryptocurrency companies also entailed the deployment of a next-stage backdoor referred to as Gopuram that's capable of running additional commands and interacting with the victim's file system.

Mandiant's investigation into the sequence of events has now revealed the patient zero to be a malicious version of a now-discontinued software provided by a fintech company called Trading Technologies, which was downloaded by a 3CX employee to their personal computer.

It described the initial intrusion vector as "a malware-laced software package distributed via an earlier software supply chain compromise that began with a tampered installer for X\_TRADER."

This rogue installer, in turn, contained a setup binary that dropped two trojanized DLLs and an innocuous executable, the latter of which is used to side-load one of the DLLs that's camouflaged as a legitimate dependency.

The attack chain then made use of open source tools like SIGFLIP and DAVESHELL to ultimately extract and execute VEILEDSIGNAL, a multi-stage modular backdoor written in C that's capable of sending data, executing shellcode, and terminating itself.

The initial compromise of the employee's personal computer using VEILEDSIGNAL enabled the threat actor to obtain the individual's corporate credentials, two after which the first unauthorized access to its network took place via a VPN by taking advantage of the stolen credentials.

Besides identifying tactical similarities between the compromised X\_TRADER and 3CXDesktopApp apps, Mandiant found that the threat actor subsequently laterally moved within the 3CX environment and breached the Windows and macOS build environments.

"On the Windows build environment, the attacker deployed a TAXHAUL launcher and COLDCAT downloader that persisted by performing DLL side-loading through the IKEEXT service and ran with LocalSystem privileges," Mandiant said. "The macOS build server was compromised with POOLRAT backdoor using Launch Daemons as a persistence mechanism."

POOLRAT, previously classified by the threat intelligence firm as SIMPLESEA, is a C/C++ macOS implant capable of collecting basic system information and executing arbitrary commands, including carrying out file operations.

UNC4736 is suspected to be a threat group with North Korean nexus, an assessment that's been reinforced by ESET's discovery of an overlapping command-and-control (C2) domain (journalide\[.\]org) employed in the supply chain attack and that of a Lazarus Group campaign called Operation Dream Job.

Evidence gathered by Mandiant shows that the group exhibits commonalities with another intrusion set tracked as Operation AppleJeus, which has a track record of carrying out financially motivated attacks.

What's more, the breach of Trading Technologies' website is said to have taken place in early February 2022 by weaponizing a then zero-day flaw in Google Chrome (CVE-2022-0609) to activate a multi-stage infection chain responsible for serving unknown payloads to the site visitors.

"The site www.tradingtechnologies\[.\]com was compromised and hosting a hidden IFRAME to exploit visitors, just two months before the site was known to deliver a trojanized X\_TRADER software package," Mandiant explained.

Another link connecting it to AppleJeus is the threat actor's previous use of an older version of POOLRAT as part of a long-running campaign disseminating booby-trapped trading applications like CoinGoTrade to facilitate cryptocurrency theft.

The entire scale of the campaign remains unknown, and it's currently not clear if the compromised X\_TRADER software was used by other firms. The platform was purportedly decommissioned in April 2020, but it was still available to download from the site in 2022.

3CX, in an update shared on April 20, 2023, said it's taking steps to harden its systems and minimize the risk of nested software-in-software supply chain attacks by enhancing product security, incorporating tools to ensure the integrity of its software, and establishing a new department for Network Operations and Security.

"Cascading software supply chain compromises demonstrate that North Korean operators can exploit network access in creative ways to develop and distribute malware, and move between target networks while conducting operations aligned with North Korea's interests," Mandiant said.

The post Update now, there's a Chrome zero-day in the wild appeared first on Malwarebytes Labs.

Google has announced an important update for Chrome to help fend off a zero-day. The update fixes several issues, and readers are advised to ensure they're using the latest version of the browser.

**Mitigation**

If you’re using Chrome on Mac, Windows, or Linux, you need to update as soon as you possibly can. If you’re using a standard Chrome setup then updates should be applied automatically. However, this won't happen if you never close your browser, or if the update is blocked by something like a fault in an installed extension.

It’s always good to check, especially when something bad is floating around potentially helping to compromise devices. One easy way to do this is navigate to **chrome://settings/help** or clicking **Settings > About Chrome.**

Chrome will notify you of the version you're on and if there's an update available. Once you've downloaded the update, reload the browser and everything should be good to go. If everything has worked as it should, your version should in theory be running the latest version. At the time of writing the most recent update being offered is now 112.0.5615.138.

This will fix eight vulnerabilities, although the update is only currently available for both Mac and Windows. The Linux version is still being worked on.

**Vulnerability**

The exploit page for CVE-2023-2136 has few details available, as is the usual pattern followed by Google when something like this happens. Details are generally held back to give people time to patch, without offering any clues to cybercriminals about how they might exploit the vulnerability. So far, the only information we have is:

> Integer overflow in Skia in Google Chrome prior to 112.0.5615.137 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)

An integer overflow is a programming error that allows an attacker to manipulate a number the program uses in a way that might be harmful. If the number is used to set the length of a data buffer (an area of memory used to hold data), an integer overflow can lead to a buffer overflow, a vulnerability that allows an attacker to overloaded a buffer with more data than it's expecting, which creates a route for the attacker to manipulate the program.

Skia is a graphics library (a set of reusable code) used by Google Chrome. In this case the error allows an attacker to escape the shackles of Chrome's "sandbox", a security feature that should prevent malicious code from affecting the system that Chrome is running on.

Update now, there's a Chrome zero-day in the wild

Mandiant found that North Korea's UNC4736 gained initial access on 3CX's network when an employee downloaded a weaponized but legitimately-signed app from Trading Technologies.

Turns out 3CX was not the original target in a recent supply chain compromise affecting customers of the video conferencing software maker: The attack came via a prior supply chain compromise involving Trading Technologies, a provider of high-performance trading software.

That makes the breach at 3CX one of the first known instances where an adversary used one supply chain attack to enable a second supply chain attack in an effort to try and breach multiple organizations. However, rather than being the victims of a targeted attack, 3CX and its customers appear to have become opportunistic victims for the threat actor, new research shows.

Researchers at Google Cloud's Mandiant discovered the chained attacks after 3CX hired the security vendor to investigate a March 2023 incident where a threat actor — now identified as North Koreas Lazarus group — used legitimate updates of 3CX's DesktopApp to deliver malware to downstream customers.

Multiple security vendors at the time reported observing legitimately signed Windows and Mac versions of the 3CX app landing on customer systems bundled with malicious installers. When users attempted to deploy the poisoned software, the malicious installers executed a sequence of actions that ended with an information stealer on their systems. Kaspersky later observed Lazarus actors dropping a second-stage backdoor, tracked as "Gopuram" on systems belonging to a small number of affected 3CX users.

Security researchers surmised that the North Korean threat actor — whom Mandiant tracks as UNC4736 — would have needed extensive access to 3CX's build environment to pull off the attack. 3CX officials themselves merely noted the issue likely had to do with one of the bundled libraries compiled into the desktop app.

**Fortuitous Download for the Hackers**

Mandiant's investigation into how exactly UNC4736 might have compromised the 3CX environment showed the threat actor gained initial access when a 3CX employee downloaded a financial trading package called X\_TRADER from the website of the developer, Trading Technologies.

UNC4736 actors had previously breached Trading Technologies systems, according to Mandiant, and inserted a backdoor in the X\_TRADER app's installation file. When the 3CX user downloaded the app from the Trading Technologies website, the installer triggered actions that resulted in a modular, multi-stage backdoor called "VEILEDSIGNAL" landing on the individual's system.

The malware contained multiple functions, including those for sending implant data, executing shell code, and for terminating itself. VEILEDSIGNAL also included two other components: one for injecting the command-and-control module on Chrome, Firefox, or Edge, and the other for listening to incoming communications.

Marius Fodoreanu, principal consultant at Mandiant and the lead investigator in the 3CX compromise, says it's unclear how UNC4736/Lazarus actors introduced the malicious installer for X\_TRADER.

"Mandiant is not performing an incident response for Trading Technologies, so we don't have direct visibility into the Trading Technologies' environment," he says. But Mandiant has observed evidence of compromise of the Trading Technologies environment as far back as 2021, Fodoreanu says.

**Lazarus Used Backdoor to Steal Credentials, Compromise 3CX Build Systems**

Fodoreanu says that following the initial compromise of the 3CX employee's computer in 2022, the threat actor stole the employee's corporate credentials. The attackers then used the administrative-level access and persistence that VEILEDSIGNAL provided on the system to eventually compromise 3CX's Windows and macOS build environments and insert malware into finished 3CX software packages.

The breach at 3CX would not have happened in this instance if the employee hadn't downloaded the malicious X\_TRADER app. That means the company became a collateral and, therefore, an opportunistic victim of the North Korean group.

"If you were starting from scratch and trying to intentionally target a company like 3CX, you would not go to Trading Technologies as an initial attack vector," Fodoreanu concedes.

However, when the threat actor discovered they had snagged a high-value victim, it is likely they pressed forward more deliberately, he says.

"Yes, we believe it likely started off as \[an\] opportunistic attack," he says. "But once they figured out that they had access to a company that likely has a lot of customers, they decided to continue to move forward and compromise the environment and then compromise the software."

**3CX Not a Trading Technologies' Customer**

Interestingly, 3CX is neither a vendor nor a customer of Trading Technologies. So, it is not clear why an employee from the company would have wanted to download X\_TRADER, a spokeswoman from Trading Technologies said in an emailed statement to Dark Reading.

"Given that this only came to our attention last week, we have not had the ability to verify the assertions in Mandiant's report," the spokeswoman said. "What we do know with certainty is that 3CX is not a vendor or a customer of Trading Technologies. There is no business relationship between the two companies."

The statement went on to note that Trading Technologies discontinued the X\_TRADER app referenced in the Mandiant report in April 2020. Mandiant itself said its investigation showed, however, that the app was still available for download in 2022. "There was no reason for anyone to download the software given that TT stopped hosting, supporting, and servicing X\_TRADER after early 2020."

**Other Victims?**

Fodoreanu says there is potential that other organizations might have downloaded the poisoned X\_TRADER app during the two years it was available on Trading Technologies' website, after the company discontinued the product.

"We suspect there are a number of organizations that don't know they're compromised yet," he says. "We're hopeful that now that this information is out, it'll help accelerate the process for companies to determine that they're compromised and contain their incidents."

Meanwhile, in a separate development, security vendor Eset this week reported on a new Lazarus campaign it is currently tracking as Operation DreamJob, which it believes is linked to the 3CX attack for multiple reasons. Peter Kalnai, senior malware researcher at Eset, says the so-called "SimplexTea" Linux malware used in the DreamJob campaign shares the same C2 network infrastructure used in the 3CX attack.

The configuration of SimplexTea also bears the same name (apdl.cf) as SIMPLESEA the macOS malware reported in the 3CX attack, Kalnai says. There are also similarities in the manner in which messages are encrypted, he says.

3CX Supply Chain Attack Tied to Financial Trading App Breach

Overcoming the limitations of consumer MFA with a new flavor of passwordless.

Twitter recently disabled SMS-based two-factor authentication (2FA) except for Twitter Blue subscribers. While the intended results may be cost-savings and boosting the number of subscribers, the decision is likely to have unintended security consequences. Even some tech-savvy people who know and care about security find Twitter's 2FA alternatives awkward enough to delay until they are forced into it, so Twitter's new policy will likely result in fewer accounts using 2FA. Educating users about how to set up authenticator apps and security keys is one solution. But that's analogous to building a faster horse.

Fundamentally, the enterprise 2FA playbook cannot be applied to consumer scenarios in equal measure because consumers can vote with their feet. Any added step will send them galloping into the arms of the competition. Thus, the Twitter news should be a call for disruption, and for solutions that protect consumer identities without introducing friction. I believe that technology is passkeys when available uniformly across the digital landscape.

**The State of Consumer MFA**

It’s broadly accepted that any multifactor authentication (MFA) is better than no MFA (I’ll use MFA here to mean authenticating your identity with two or more factors). MFA solutions prevent bad actors from accessing resources using only a victim's primary credentials. Our CISO once observed that MFA and adaptive authentication would have prevented 95% of the breaches she has seen.

But not all MFA is created equal. Some factors are weaker than others, particularly against targeted attacks. Security questions, SMS, voice, and email-based one-time passwords are considered low-assurance factors. All these factors are vulnerable to phishing. Attackers can bypass weaker factors by "guessing" the authenticator code; intercepting the code-containing SMS; or creating "alert fatigue" by bombarding the user with messages until they complete the MFA challenge.

**MFA Bypass Attacks**

Recent research found more than 113 million MFA bypass (registration required) attempts against consumer and SaaS applications over a 90-day period, representing the highest baseline level of attacks of any year on record. Given what we know about weaker factors, you'd be forgiven for thinking Twitter's decision to disable text-based authentication is a good one. But as with most things in identity, there is more complexity that meets the eye, particularly when we look at MFA adoption issues.

**The Trouble With MFA Adoption**

The challenge of getting users to sign up for any form of MFA lies in the technology's origin story. Passwords predate modern online services by thousands of years (just think about "Open, Sesame" in "Ali Baba and the 40 Thieves"). Two-factor authentication entered the picture much later as a way for enterprises and governments to protect their internal systems with something you know (password) and something you have (device, code, or security key).

Technologies developed in an enterprise context have historically prioritized security. The administrator has the power to enforce security measures across the employee base to protect the company's interests. When organizations try to use the same playbook with consumers, they fail, because consumers can vote with their feet. And the impact can quickly become existential.

So, what about authenticator apps? For us in the industry, this might look like the obvious technical alternative to SMS-based methods. But few end users are this digitally savvy. The more likely result of forcing something like an authenticator app or security key at scale is that people just won't use it.

**Phishing-Resistant Authentication**

The transition to phishing-resistant factors offers one potential solution to consumer MFA woes. FIDO and WebAuthn rely on public key cryptography and biometrics to significantly improve both security and the user experience. When using public key cryptography, there are no codes or secrets to be stolen. Users go through a biometric check on their device to unlock access to their private key, which is way faster than entering an SMS code. There are nuances in how biometric data is validated that can make a big difference for data privacy and security.

**The Passkeys Opportunity**

Despite exciting progress toward more secure and usable factors, the best MFA mechanism for consumers really isn't MFA at all — it's passkeys. Passkeys are a FIDO authenticator with the advantage of being backed up to the cloud, so if you lose your device or buy a new one, all you must do is sign into your iCloud or Google Play account to recover your passkeys. Passkeys use public key cryptography and device biometrics, making them resistant to many known attacks, and are easy for the user.

Should passkeys have been used on Twitter? Absolutely, but they may not have been a clear option at the time. Supporting something new is always expensive from the engineering perspective. If passkeys had been an option, the experience for the user might have looked something like this:

1.  The user signs into Twitter on their mobile device with username and password;
2.  They are asked if they would like to use a passkey to authenticate next time; and
3.  The user receives a biometric prompt from then on without needing to install anything. They can even go to their Mac and open Twitter in Safari, and the passkey will be automatically synced to that device.

Offering passkey authentication currently requires some reworking, but it's easier and more cost-effective than SMS. Unfortunately, passkeys are not yet uniformly distributed. Apple added support early on, followed by Android and Chrome. Windows currently supports passkeys on a single device.

Whenever you're asking people to change, you need to take concrete steps to make the transition easier. In the case of Twitter, that would be explaining to users what they can do to change their second factor, to avoid them dropping MFA entirely. This would be an amazing passkey adoption opportunity if the industry were ready. We're already in a fantastic position to encourage people to use this flavor of passwordless. What comes next is making it easier for developers to implement the necessary changes in their apps and websites. A future with fewer passwords may not be so far away after all.

Twitter's 2FA Policy Is a Call for Passkey Disruption
