North Korean state-sponsored hackers have been linked to two recent cyberattack campaigns: one involving a spear-phishing attack on JumpCloud and the other targeting tech employees on GitHub through a social engineering campaign. "Fewer than 5 JumpCloud customers were impacted and fewer than 10 devices total were impacted, out of more than 200,000 organizations who rely on the JumpCloud platform for a variety of identity, access, security, and management functions,".

GitHub is warning of a social engineering campaign targeting the accounts of developers in the blockchain, cryptocurrency, online gambling, and cybersecurity sectors to infect their devices with malware. In a new security alert, GitHub warns that the Lazarus Group is compromising legitimate accounts or creating fake personas that pretend to be developers and recruiters on GitHub and social media.

The source code for the BlackLotus UEFI bootkit has leaked online, allowing greater insight into a malware that has caused great concern among the enterprise, governments, and the cybersecurity community. BlackLotus is a Windows-targeting UEFI bootkit that bypasses Secure Boot on fully patched Windows 11 installs, evades security software, persists on an infected system, and executes payloads with the highest level of privileges in the operating system.

"In this instance, the PoC is a wolf in sheep's clothing, harboring malicious intent under the guise of a harmless learning tool," Uptycs researchers Nischay Hegde and Siddartha Malladi said. The repository masquerades as a PoC for CVE-2023-35829, a recently disclosed high-severity flaw in the Linux kernel.

GitHub announced today the introduction of passwordless authentication support in public beta, allowing users to upgrade from security keys to passkeys. To activate passkeys on your account, click your profile photo in the top-right corner of any GitHub page.

Millions of GitHub repositories may be vulnerable to dependency repository hijacking, also known as "RepoJacking," which could help attackers deploy supply chain attacks impacting a large number of users. The warning comes from AquaSec's security team, 'Nautilus,' who analyzed a sample of 1.25 million GitHub repositories and found that about 2.95% of them to be vulnerable to RepoJacking.

Millions of software repositories on GitHub are likely vulnerable to an attack called RepoJacking, a new study has revealed. Aqua said a threat actor could leverage websites like GHTorrent to extract GitHub metadata associated with any public commits and pull requests to compile a list of unique repositories.

At least half of dozen GitHub accounts from fake researchers associated with a fraudulent cybersecurity company have been observed pushing malicious repositories on the code hosting service. VulnCheck, which discovered the activity, said, "The individuals creating these repositories have put significant effort into making them look legitimate by creating a network of accounts and Twitter profiles, pretending to be part of a non-existent company called High Sierra Cyber Security."

Hackers are impersonating cybersecurity researchers on Twitter and GitHub to publish fake proof-of-concept exploits for zero-day vulnerabilities that infect Windows and Linux with malware. These malicious exploits are promoted by alleged researchers at a fake cybersecurity company named 'High Sierra Cyber Security,' who promote the GitHub repositories on Twitter, likely to target cybersecurity researchers and firms involved in vulnerability research.

Open-source GitHub cybersecurity projects, developed and maintained by dedicated contributors, provide valuable tools, frameworks, and resources to enhance security practices. Faraday is used through the terminal and allows users to take advantage of community tools in a multiuser environment.
