On require of the package, init.js selects a platform-specific payload, downloads opaque bytes over HTTPS from a rotating set of anonymous Cloudflare Workers hosts (oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev), with a fallback covert channel using DNS TXT lookups against sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru to reassemble a base64 payload. The downloaded bytes are written to /var/tmp/.cache on Linux or %TEMP%/dotnet_diag_.exe on Windows, chmod 0755, and spawned detached via spawn("/bin/sh") or spawn("cmd"). Hostnames are constructed from split-string arrays joined at runtime to evade static analysis, and file names (.cache_, dotnet_diag_.exe, /tmp/.analytics_state) plus DISABLE_TELEMETRY/DO_NOT_TRACK env checks are used as a telemetry cover story. There is no pinning, no integrity check, and the destinations are unrelated to any legitimate publisher; installing or importing the package results in full-host code execution under attacker control.
- CWE-506 - The product contains code that appears to be malicious in nature.
