This week we talked about: PolinRider jumps the fence — Paul's research on North Korea's automated repo-hijacking campaign spreading into the Go and PHP ecosystems without any extra effort from the threat actors Cybersecurity startup publishes infostealers to npm — a vendor publishing malicious packages to manufacture threat data for its own marketing, and getting their npm account pulle...

This week we talked about: GitHub’s two new account protection features: NPM added a 72-hour read-only lockout for high-impact accounts triggered by an email change or 2FA recovery code use, aimed at slowing account takeovers.

This week we talked about: DPRK Lazarus Group trends in software supply chain malware: Three active techniques he's observing from North Korea's Lazarus Group.

Mastra Package Compromise: Threat actors hijacked the entire Mastra npm organization (116 packages) after a maintainer was targeted with a ClickFix-style attack that stole his credentials. Rather than injecting malware directly into Mastra packages, attackers pre-staged a typosquatted package called 'easy-day-js' and added it as a dependency across the org. The malware differs from the s...

This week Jenn and Paul covered: OSV false positives from AWS Inspector: AWS's automated malware detection pipeline submitted 157 false positive entries to osv.dev. The entries were merged before anyone caught the errors. When the community began pointing out that some of those "false positives" were actually real malware, AWS started adding some back, making this a mess on both end...

This week Jenn and Paul cover: npm Staged Publishing: npm's new feature adds a human approval checkpoint before a package goes live. Real improvement, real caveats. We walk through what it does, where it falls short, and the questions the docs still don't answer.
