devplatform-eslint-config@35.8.9
Malicious code in devplatform-eslint-config (npm)
Analysis
devplatform-eslint-config@35.8.9 is a trojanized eslint-config package that downloads and executes a remote binary when required. On load it contacts rotating Cloudflare Workers C2 endpoints (oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev) over HTTPS and fetches a platform-specific payload from /pkg/package, /pkg/package-arm64, /pkg/loader_mac, or /pkg/package.exe. If those fail it falls back to a DNS-TXT-based download channel under c[.]sdk[.]dl[.]wel1[.]ru (also ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, net[.]dl[.]wel1[.]ru). The downloaded binary is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe in the temp dir on Windows), made executable, and launched as a detached background process (cmd.exe /c start /b on Windows, /bin/sh -c on Unix). The package also ships a decoy telemetry module that fingerprints hostname, CPU, and memory.
