Fake security tools on GitHub push backdoors and infostealers
Cybersecurity professionals are being targeted with infected security projects on GitHub that deploy a backdoor and information stealer malware. The campaign started about two years ago and initially targeted crypto wallet users, but recently the threat actor switched focus and published malicious repositories for automating scans, security testing, and log analysis. Researchers at cybersecurity company […]
Hugging Face malware campaign returns to hijack GPUs for crypto mining
A cryptomining and backdoor campaign that abuses Hugging Face model repositories came back within days of being taken down. Its most popular malicious model was downloaded more than 28,000 times. Separately, researchers flagged a fake Solana starter kit on GitHub, live since late 2025, that is positioned to trick AI coding agents into installing a […]
OVHcloud CLI releases backdoored on GitHub to steal developer secrets
French cloud and hosting provider OVHcloud is warning users that attackers compromised its open-source command-line interface (CLI) tool to distribute information-stealing malware. The attacker hijacked a developer’s GitHub account to gain access to the OVHcloud CLI repository and modify versions 0.11.0 through 0.15.0 of the tool. OVHcloud offers the CLI tool as an alternative for […]
FakeGit malware campaign returns with 17,610 malicious GitHub repos
More than 17,000 fake repositories on GitHub are distributing the SmartLoader malware after the FakeGit campaign reactivated earlier this month to push the StealC infostealer. The operator uses mostly throwaway accounts, but researchers identified at least 700 accounts that appear to belong to legitimate developers. The malicious repositories use convincing README instructions with a download […]
Over 543,000 valid credentials exposed in public GitHub repositories
More than 543,000 credentials exposed in public GitHub repositories were still valid in July despite the platform’s security measures to prevent accidental leaks of sensitive data. Data pulled from scanning 224 million repositories and more than 58 billion files show that the median time a unique credential remained publicly accessible was 784 days. The research […]
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 […]

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.
