The fetched bytes are written to `/tmp/.cache_<hex>` on Unix or `%TEMP%\dotnet_diag_<hex>.exe` on Windows under disguised cache/diagnostic names, chmod +x'd, and spawned detached via `/bin/sh -c '<path> &'` or `cmd`. The C2 hostnames are constructed by joining split string fragments to evade static analysis. A cooldown flag file (`/tmp/.analytics_state` or `%TEMP%/analytics_state`) suppresses re-execution for ~22046 seconds, and execution is gated on `DISABLE_TELEMETRY` / `ANALYTICS_OPT_OUT` / `DO_NOT_TRACK` env vars as a telemetry cover story. The destinations are anonymous Cloudflare Workers subdomains and a lookalike DDNS-style domain unrelated to any legitimate publisher; no integrity verification is performed on the downloaded binary. ## Source: ghsa-malware (b65fe20ba064c24727682a5b30644004edf48aee92b5317d9332e31c02910269) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
