The Axios supply chain attack we covered on March 31 has now been attributed to UNC1069, a North Korean threat group linked to BlueNoroff that specializes in financially motivated attacks against crypto exchanges and financial institutions. Google's Mandiant confirmed the attackers social-engineered the lead maintainer through a fake video call, deploying a RAT via the compromised npm account. Socket warns this wasn't a one-off - the same actors have compromised accounts spanning some of the most widely depended-upon packages in the npm registry.
Attackers hijacked the npm account of Axios's lead maintainer and published two poisoned versions of one of JavaScript's most popular libraries - 83 million weekly downloads. Versions 1.14.1 and 0.30.4 inject a hidden dependency called plain-crypto-js that drops a cross-platform RAT targeting macOS, Windows, and Linux. The malware phones home within seconds of npm install, then deletes itself to avoid detection. Both release branches were hit within 39 minutes of each other.
