It retrieves an opaque platform payload, writes 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 permissions. - **Evidence paths:** package.json, index.js, \_init.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:46:22.447Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, temp-file drop, and detached shell execution - **Attack narrative:** Loading the advertised token-manager entrypoint silently imports \_init.js. That module fetches a platform-specific opaque payload from hard-coded Workers hosts, with DNS TXT reconstruction as fallback; it drops the bytes into a temporary executable file and launches it detached via cmd.exe or /bin/sh. The payload is neither authenticated nor package-aligned. - **Rationale:** This is a concrete import-time remote-code-execution chain unrelated to the stated identity-client function. Absence of an install hook does not mitigate execution when consumers import the main entrypoint. - **Files touched:** index.js, \_init.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe, lib/telemetry.js - **Network endpoints:** oob-worker.cf103-070.workers.dev/pkg/package, oob-worker.cf101-adf.workers.dev/pkg/package, oob-worker.cf102-baf.workers.dev/pkg/package, tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, win.dl.well1.site ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js:26 imports \_init on every package import., \_init.js downloads opaque binaries from worker hosts or DNS TXT records., \_init.js writes the payload to /var/tmp or Windows temp, chmods it, and launches it detached., \_init.js:119-130 executes the downloaded path through child\_process and a shell., lib/telemetry.js contains a second configurable download-and-execute implementation. - **Evidence against:** package.json has no npm lifecycle scripts., No credential or environment-value exfiltration was found; environment variables only control paths and opt-out. ## Public findings ### 1.
