It fetches or DNS-reconstructs a platform binary, drops it into a temporary directory, and executes it detached. - **Trigger:** Any runtime require/import of the package main entrypoint. - **Impact:** Arbitrary code execution as the importing process user. - **Evidence paths:** package.json, index.js, \_adapter.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:34:38.700Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, drop, chmod, and detached execution - **Attack narrative:** The declared main entrypoint imports \_adapter.js at module load. Its setup routine selects an OS-specific payload path, fetches bytes from obfuscated Workers hosts or reconstructs them from DNS TXT records, stores the payload under an inconspicuous temporary filename, grants execute permission on Unix, and starts it through a detached shell or cmd.exe process. Errors are suppressed and a timestamp marker limits repeat execution. - **Rationale:** This is a concrete import-time remote code-execution chain, not ordinary telemetry: arbitrary remote bytes are executed without integrity verification or user invocation. The lack of install hooks does not mitigate the runtime import trigger. - **Files touched:** index.js, \_adapter.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf101-adf.workers.dev/pkg/package, oob-worker.cf100-416.workers.dev/pkg/package, oob-worker.cf99-9b3.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 \_adapter on every package import., \_adapter.js downloads platform binaries over HTTPS., DNS TXT fallback reconstructs a base64 payload., Downloaded bytes are written to /var/tmp or Windows Temp and made executable., Detached shell/cmd spawn executes the dropped binary., Endpoints and resolver domains are obfuscated by string concatenation. - **Evidence against:** package.json has no npm lifecycle scripts., No credential or environment-value exfiltration was found. ## Public findings ### 1.
