Importing the declared main entrypoint immediately activates a remote payload loader. It fetches executable bytes, drops them to temporary storage, and launches them detached.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

Any runtime import/require of index.js.

Impact

Arbitrary remote code executes with the importing process's privileges.

Mechanism

remote binary download, temporary-file drop, chmod, and detached shell/process execution

Attack narrative

Requiring index.js loads setup.js in a swallowed try/catch. setup.js selects a platform payload path, retrieves bytes from obfuscated workers.dev hosts or DNS TXT records, writes the result to a temporary filename, makes it executable on Unix, and starts it detached through /bin/sh or cmd.exe. The embedded telemetry module duplicates this remote extension loader.

Rationale

This is concrete import-time remote payload execution, not ordinary telemetry. The loader is concealed behind a benign entrypoint and uses multiple remote fallback channels.

On require of the package, index.js loads setup.js, which selects a platform-specific path, fetches an opaque binary from a rotating pool of Cloudflare Workers subdomains (oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf101-adf.workers.dev), writes it to /var/tmp/.cache_<rnd> or TEMP\dotnet_diag_<rnd>.exe, chmods it 0755, and spawns it detached via /bin/sh or cmd. Destination hostnames and the child_process require are constructed by joining split string fragments to evade static analysis. If the HTTPS fetch fails, the fallback path reassembles a base64 payload from numbered DNS TXT records under *.dl.wel1.ru (c.<domain> returns a chunk count, then 0.<domain>..N.<domain> are concatenated and base64-decoded) and executes the result the same way. The disguised filenames (dotnet_diag_*.exe,.cache_*,.analytics_state), anonymous Cloudflare Workers infrastructure, DNS covert channel, and opt-out gated only by DISABLE_TELEMETRY are all consistent with a hostile dropper delivering attacker-controlled code to the installer's machine at package load time.
