damir-cbr-dawdntrnssbf@35.8.1
Malicious code in damir-cbr-dawdntrnssbf (npm)
Analysis
On require, this package downloads and executes a remote binary. It fetches a payload over HTTPS from oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, and oob-worker[.]cf101-adf[.]workers[.]dev at path /pkg/package (or /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe by platform). If HTTPS is blocked it falls back to a DNS-TXT chunked base64 transfer from the wel1[.]ru domain family (c[.]sdk[.]dl[.]wel1[.]ru, 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 via cmd.exe /c start /b or /bin/sh -c '... &'.
