dolyame-ui-draghoc@35.8.1
Malicious code in dolyame-ui-draghoc (npm)
Analysis
On require, the package runs a loader that downloads a second-stage binary over HTTPS from four Cloudflare Workers endpoints (oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev) at /pkg/package, with a DNS-TXT fallback channel that reassembles base64 chunks from c[.]sdk[.]dl[.]wel1[.]ru. The downloaded binary is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe in %TEMP% on Windows), made executable, and launched as a detached background process via cmd.exe /c start /b or /bin/sh -c "<path> &". A stamp file (/tmp/.analytics_state) throttles repeat downloads.
