It retrieves an unverified platform payload, saves it to temporary storage, and executes it detached. - **Trigger:** Any runtime require/import of index.js. - **Impact:** Arbitrary remote code executes with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_shim.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-07T11:16:05.279Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic remote binary download and detached execution - **Attack narrative:** index.js silently requires \_shim.js at import time. The shim fetches a large platform-specific payload from concealed worker hosts, with DNS TXT reconstruction through .ru domains as fallback; it writes that payload into a temp path, marks it executable on Unix, and launches it via shell/cmd detached. This is an unconsented remote-code execution chain. - **Rationale:** The package has no install hook, but its normal import path automatically downloads and executes remote, unverified binaries. The claimed telemetry/profiler functionality does not justify hidden detached execution from unrelated hosts. - **Files touched:** index.js, \_shim.js, lib/telemetry.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%/analytics\_state, %TEMP%/dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf101-adf.workers.dev/pkg/package, oob-worker.cf102-baf.workers.dev/pkg/package, oob-worker.cf100-416.workers.dev/pkg/package, sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js imports \_shim on every package import., \_shim.js downloads platform-specific payloads over HTTPS or DNS TXT., \_shim.js writes payloads to /var/tmp or Windows Temp, chmods them, then spawns them detached., Remote hosts and .ru DNS fallback are obfuscated by string concatenation., lib/telemetry.js duplicates the download-to-execute profiler path. - **Evidence against:** package.json has no npm lifecycle scripts., No credential harvesting or exfiltration path was confirmed. ## Public findings ### 1.
