Open-Source Repositories: The Front Line in Software Supply Chain Attacks
Modern software is built on open-source. Developers rely on public repositories like npm, PyPI, and Maven Central to move fast, avoid reinventing the wheel, and ship updates continuously. But this speed and openness come at a cost: your software supply chain is now a primary attack surface. Attackers have figured this out-and they're exploiting it. How Open-Source Dependencies Become Attack Vectors Open-source packages are easy to install and often trusted implicitly. That's exactly what makes them so appealing to threat actors. Here's how attackers are weaponizing open-source: 1. Typosquatting Malicious packages are uploaded with names that closely mimic legitimate libraries (e.g., expresss instead of express). If a developer makes a typo or auto-installs a dependency, they may unknowingly install malware. 2. Hijacked or Abandoned Projects Attackers take over dormant projects-sometimes by buying expired domains or credentials-and inject malicious code into new releases. Users update as usual, unaware of the compromise.…
