XZ Backdoor: Navigating The Complexities Of Supply Chain Attacks Detected By Accident
summary
Accidentally discovered malicious XZ backdoor binaries are injected into build artifacts so source looks clean while released packages in Fedora Debian and Maven contain backdoor sockets that survived for months; a VS Code typosquatting extension exfiltrated code and metadata to a CNC server and gained hundreds of installs via fake popularity; a small vendor’s double supply‑chain compromise used side‑loaded DLLs to reach CI builders and produce signed malware. Defenses tested: extension scanning, attestation/reproducible builds and disposable build servers.
