GitHub Actions re-enabled with Mini Shai-Hulud payload still active
Two third-party GitHub Actions previously compromised in a Mini Shai-Hulud campaign were re-enabled by their maintainer and remained accessible for more than a week despite still pointing to malicious code. After being compromised on May 18, the GitHub security team removed actions-cool/issues-helper and actions-cool/maintain-one-comment, preventing any downstream workflow from downloading malware. According to researchers at […]
Malicious npm packages evade install-script defenses at runtime
An ongoing npm malware campaign involving the ‘indexed-btree’ package shows how threat actors bypass supply chain defenses by hiding malicious code in a package’s normal runtime behavior rather than in installation scripts. The package, spotted by Checkmarx researchers, attempts to impersonate the legitimate ‘sorted-btree’ library and has already amassed 2 million weekly downloads. The campaign may […]
Fake LastPass Authenticator GitHub repos push new Rapuncel infostealer
An ongoing malware campaign uses SEO-optimized GitHub repositories to impersonate well-known software firms to push a previously undocumented information stealer called Rapuncel. LastPass and Delphos Labs uncovered the campaign, which they report impersonates the password manager brand and at least 39 other companies. Alongside the Rapuncel infostealer, the repositories deliver a Microsoft-signed kernel driver that […]
Microsoft confirms GitHub is down worldwide
GitHub is down for some users as a widespread outage is causing errors across the website, API, Actions, Pull Requests, and several other services. GitHub confirmed the outage at 9:40 AM EDT on August 17, 2026, when it said it was investigating reports of performance problems affecting some of its services. The problems quickly spread across several […]
Mozilla updates GPG signing key for Firefox releases after exposure
Mozilla announced today that it updated the GPG key used to sign Firefox and Thunderbird releases after it was accidentally exposed on GitHub. However, in a Monday blog post, it noted that the risk of a supply chain attack in which threat actors could distribute malicious installers signed with the exposed key is low because only a […]
GitHub, PyPI add time-based defenses against supply chain attacks
GitHub and PyPI (Python Package Index) have introduced a time-based mechanism in the Dependabot dependency management tool to protect against supply-chain attacks and to limit their impact. Specifically, Dependabot comes with a default three-day cooldown setting, while PyPI will reject new files uploaded to releases older than 14 days. The measure comes after the two […]
FakeGit campaign uses 7,600 GitHub repos to push SmartLoader malware
A large-scale operation dubbed ‘FakeGit’ is pushing SmartLoader and StealC malware through 7,600 malicious GitHub repositories that accumulated more than 14 million downloads. Over 800 repositories pretended to be AI skills or MCP servers and appeared more than 600 times in public AI registries and catalogs. This increased the likelihood of being discovered by AI […]
AsyncAPI npm packages infected with credential-stealing malware
Five malicious versions of AsyncAPI packages were published to the Node Package Manager (npm) in a supply-chain attack that delivered a remote access trojan with info-stealing capabilities. The threat actor exploited a misconfigured GitHub Actions workflow and pushed trojanized packages in the @asyncapi namespace that had a cummulative weekly download count of more than 2.25 […]
Nearly 300 GitHub repos pose as legit software to push malware
A threat actor has published hundreds of fake GitHub repositories impersonating legitimate software and security projects to distribute infostealer malware. The campaign drew traffic from search results for security products, cryptocurrency services, financial tools, developer utilities, secure email providers, macOS utilities, and gaming software. The malware collects data from more than 19 web browsers, steals […]
Clean GitHub repo tricks AI coding agents into running malware
An agentic coding tool tasked with cloning and setting up a seemingly benign GitHub repository could execute a malicious payload that remains invisible to security scanners, AI agents, and human reviewers. Researchers at Mozilla’s Zero Day Investigative Network (0DIN) AI security platform say that the compromise happens with “no exploit code, no warning, no suspicious […]
