Official description
On require(), index.js loads shim.js which reconstructs C2 hostnames from split string arrays (Cloudflare Workers subdomains oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf101-adf.workers.dev) with a DNS-TXT fallback resolver chain (sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru), downloads a platform-specific binary via https.get to /pkg/package or /pkg/package.exe, writes it to /var/tmp/.cache<hex> on Unix or %TEMP%\dotnet_diag_<hex>.exe on Windows, chmods it 0755, and spawns it detached via /bin/sh -c or cmd with.unref(). Filesystem stamp and env-var checks are used to avoid repeat execution. Cover-story comments ("analytics", "telemetry", "CDN compatibility") accompany the obfuscated destinations. The behavior has no relation to the package's stated purpose.
What should I do about MAL-2026-12933?
