GitHub is moving to strengthen software supply chain security by updating "actions/checkout" to block pwn request attacks that exploit the risky use of the "pull_request_target workflow" trigger to run malicious code with the workflow's full privileges

GitHub has announced what it said are "breaking changes" coming to npm version 12, one of which turns off install scripts by default to combat software supply chain threats

A large-scale npm supply chain attack compromised over 90 versions of @redhat-cloud-services packages, silently infecting CI/CD environments and developer systems. The malicious code steals credentials from GitHub, cloud platforms, and local machines, then spreads like a worm by republishing trusted packages. Discover how the attack works, what data is at risk, and the steps you can take to protect your organization. The post Preinstall to persistence: Inside the Red Hat npm Miasma credential-stealing campaign appeared first on Microsoft Security Blog.

A supply chain attack targeting the Laravel Lang localization packages has exposed developers to a sophisticated credential-stealing malware campaign after attackers abused GitHub version tags to distribute malicious code through Composer packages. [...]

A new "coordinated" supply chain attack campaign has impacted eight packages on Packagist including malicious code designed to run a Linux binary retrieved from a GitHub Releases URL

In yet another software supply chain attack, threat actors have compromised the popular GitHub Actions workflow, actions-cool/issues-helper, to run malicious code that harvests sensitive credentials and exfiltrates them to an attacker-controlled server

JavaScript Repository Contends With Wormable Malicious CodeAn apparent "Dune" aficionado is responsible for the first self-propagating attack on the npm JavaScript repository in what one security company has called one of the most severe JavaScript supply-chain attacks so far. A malicious script exfiltrated data to GitHub repositories named "Shai-Hulud."

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday added a vulnerability linked to the supply chain compromise of the GitHub Action, tj-actions/changed-files, to its Known Exploited Vulnerabilities (KEV) catalog

Malicious Code Injected in reviewdog Just Hours Before tj-actions BackdooredJust days after researchers discovered an attack that subverted a widely used tool for software development platform GitHub, they discovered a second, prior attack, as part of what one expert said may be "a chain of supply chain attacks eventually leading to a specific high-value target."

Cybersecurity researchers have disclosed details of a new supply chain attack vector dubbed Rules File Backdoor that affects artificial intelligence (AI)-powered code editors like GitHub Copilot and Cursor, causing them to inject malicious code

Over 23,000 Code Repositories at Risk After Malicious Code Added to GitHub ActionAttackers subverted a widely used tool for software development environment GitHub, potentially allowing them to steal secrets from thousands of private code repositories as well as compromise other, widely used "open source libraries, binaries and artifacts" that use the tool, experts warned.

Threat actors are now taking advantage of GitHub's search functionality to trick unsuspecting users looking for popular repositories into downloading spurious counterparts that serve malware

Unidentified adversaries orchestrated a sophisticated attack campaign that has impacted several individual developers as well as the GitHub organization account associated with Top.gg, a Discord bot discovery site
