Microsoft is using engineers in China to help maintain the Defense Department’s computer systems—with minimal supervision by U.S. personnel—leaving some of the nation’s most sensitive data vulnerable to hacking from its leading cyber adversary, a ProPublica investigation has found.

The arrangement, which was critical to Microsoft winning the federal government’s cloud computing business a decade ago, relies on U.S. citizens with security clearances to oversee the work and serve as a barrier against espionage and sabotage...

The TL;DR is that this time, we ended up discovering ~150 Amazon S3 buckets that had previously been used across commercial and open source software products, governments, and infrastructure deployment/update pipelines—and then abandoned...

On December 4, a malicious version 8.3.41 of the popular AI library ultralytics ­—which has almost 60 million downloads—was published to the Python Package Index (PyPI) package repository. The package contained downloader code that was downloading the XMRig coinminer. The compromise of the project’s build environment was achieved by exploiting a known and previously reported GitHub Actions script injection.

Lots more details at that link. Also ...

Though the deadly operations were stunning, none of the elements used to carry them out were particularly new. The tactics employed by Israel, which has neither confirmed nor denied any role, to hijack an international supply chain and embed plastic explosives in Hezbollah devices have been used for years. What’s new is that Israel put them together in such a devastating and extravagantly public fashion, bringing into stark relief what the future of great power competition will look like—in peacetime, wartime and the ever expanding ...

Cybersecurity researchers from JFrog recently discovered a GitHub Personal Access Token in a public Docker container hosted on Docker Hub, which granted elevated access to the GitHub repositories of the Python language, Python Package Index (PyPI), and the Python Software Foundation (PSF).

JFrog discussed what could have happened:

The implications of someone finding this leaked token could be extremely severe. The holder of such a token would have had administrator access to all of Python’s, PyPI’s and Python Software Foundation’s repositories, supposedly making it possible to carry out an extremely large scale supply chain attack...

On Thursday, researchers from security firm Binarly revealed that Secure Boot is completely compromised on more than 200 device models sold by Acer, Dell, Gigabyte, Intel, and Supermicro. The cause: a cryptographic key underpinning Secure Boot on those models that was compromised in 2022. In a public GitHub repository committed in December of that year, someone working for multiple US-based device manufacturers published what’s known as a platform key, the cryptographic key that forms the root-of-trust anchor between the hardware device and the firmware that runs on it. The repository was located at https://github.com/raywu-aaeon/Ryzen2000_4000.git, and it’s not clear when it was taken down...

A software maker serving more than 10,000 courtrooms throughout the world hosted an application update containing a hidden backdoor that maintained persistent communication with a malicious website, researchers reported Thursday, in the latest episode of a supply-chain attack.

The software, known as the JAVS Viewer 8, is a component of the JAVS Suite 8, an application package courtrooms use to record, play back, and manage audio and video from proceedings. Its maker, Louisville, Kentucky-based Justice AV Solutions, says its products are used in more than 10,000 courtrooms throughout the US and 11 other countries. The company has been in business for 35 years...

This raises the possibility that the leaked key could push out updates that would infect a computer’s most nether regions without triggering a warning. To make matters worse, Matrosov said, MSI doesn’t have an automated patching process the way Dell, HP, and many larger hardware makers do. Consequently, MSI doesn’t provide the same kind of key revocation capabilities.

Delivering a signed payload isn’t as easy as all that. “Gaining the kind of control required to compromise a software build system is generally a non-trivial event that requires a great deal of skill and possibly some luck.” But it just got a whole lot easier...

Researchers at Russian cybersecurity firm Kaspersky today revealed that they identified a small number of cryptocurrency-focused firms as at least some of the victims of the 3CX software supply-chain attack that’s unfolded over the past week. Kaspersky declined to name any of those victim companies, but it notes that they’re based in “western Asia.”

Security firms CrowdStrike and SentinelOne last week pinned the operation on North Korean hackers, who compromised 3CX installer software that’s used by 600,000 organizations worldwide, according to the vendor. Despite the potentially massive breadth of that attack, which SentinelOne dubbed “Smooth Operator,” Kaspersky has now found that the hackers combed through the victims infected with its corrupted software to ultimately target fewer than 10 machines­—at least as far as Kaspersky could observe so far—­and that they seemed to be focusing on cryptocurrency firms with “surgical precision.”...

Mandiant uncovered a socially engineered supply chain operation focused on Ukrainian government entities that leveraged trojanized ISO files masquerading as legitimate Windows 10 Operating System installers. The trojanized ISOs were hosted on Ukrainian- and Russian-language torrent file sharing sites. Upon installation of the compromised software, the malware gathers information on the compromised system and exfiltrates it. At a subset of victims, additional tools are deployed to enable further intelligence gathering. In some instances, we discovered additional payloads that were likely deployed following initial reconnaissance including the STOWAWAY, BEACON, and SPAREPART backdoors...

According to company documents publicly filed in Russia and reviewed by Reuters, Pushwoosh is headquartered in the Siberian town of Novosibirsk, where it is registered as a software company that also carries out data processing. It employs around 40 people and reported revenue of 143,270,000 rubles ($2.4 mln) last year. Pushwoosh is registered with the Russian government to pay taxes in Russia...

Prevention is often seen as the responsibility of the software developer, as they are required to securely develop and deliver code, verify third party components, and harden the build environment. But the supplier also holds a critical responsibility in ensuring the security and integrity of our software. After all, the software vendor is responsible for liaising between the customer and software developer. It is through this relationship that additional security features can be applied via contractual agreements, software releases and updates, notifications and mitigations of vulnerabilities...

Nobelium has been attempting to replicate the approach it has used in past attacks by targeting organizations integral to the global IT supply chain. This time, it is attacking a different part of the supply chain: resellers and other technology service providers that customize, deploy and manage cloud services and other technologies on behalf of their customers. We believe Nobelium ultimately hopes to piggyback on any direct access that resellers may have to their customers’ IT systems and more easily impersonate an organization’s trusted technology partner to gain access to their downstream customers. We began observing this latest campaign in May 2021 and have been notifying impacted partners and customers while also developing new technical assistance and guidance for the reseller community. Since May, we have notified more than 140 resellers and technology service providers that have been targeted by Nobelium. We continue to investigate, but to date we believe as many as 14 of these resellers and service providers have been compromised. Fortunately, we have discovered this campaign during its early stages, and we are sharing these developments to help cloud service resellers, technology providers, and their customers take timely steps to help ensure Nobelium is not more successful...

This weekend’s attack was carried out with almost surgical precision. According to Cybereason, the REvil affiliates first gained access to targeted environments and then used the zero-day in the Kaseya Agent Monitor to gain administrative control over the target’s network. After writing a base-64-encoded payload to a file named agent.crt the dropper executed it.

[…]

The ransomware dropper Agent.exe is signed with a Windows-trusted certificate that uses the registrant name “PB03 TRANSPORT LTD.” By digitally signing their malware, attackers are able to suppress many security warnings that would otherwise appear when it’s being installed. Cybereason said that the certificate appears to have been used exclusively by REvil malware that was deployed during this attack...

Today, developers at small or large companies use package managers to download and import libraries that are then assembled together using build tools to create a final app.

This app can be offered to the company’s customers or can be used internally at the company as an employee tool.

But some of these apps can also contain proprietary or highly-sensitive code, depending on their nature. For these apps, companies will often use private libraries that they store inside a private (internal) package repository, hosted inside the company’s own network...

China’s exploitation of products made by Supermicro, as the U.S. company is known, has been under federal scrutiny for much of the past decade, according to 14 former law enforcement and intelligence officials familiar with the matter. That included an FBI counterintelligence investigation that began around 2012, when agents started monitoring the communications of a small group of Supermicro workers, using warrants obtained under the ...
