It retrieves a platform binary, writes it to a temporary location, and runs it detached. - **Trigger:** Any runtime require/import of the package entrypoint. - **Impact:** Arbitrary remote code executes with the importing process's permissions. - **Evidence paths:** package.json, index.js, \_adapter.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-02T14:26:19.391Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time remote binary download, drop, chmod, and detached execution - **Attack narrative:** The package entrypoint silently requires \_adapter.js. On import, that module contacts rotated workers.dev hosts or reconstructs a binary from DNS TXT records, writes it into a temp directory, makes it executable on Unix, and starts it detached via a shell or cmd.exe. A short-lived marker suppresses repeat runs. - **Rationale:** This is a concrete import-time remote-code-execution chain unrelated to the declared config SDK functionality. The lack of npm lifecycle hooks does not mitigate runtime import execution. - **Files touched:** index.js, \_adapter.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%/analytics\_state, %TEMP%/dotnet\_diag\_\.exe - **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, oob-worker.cf100-416.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 imports \_adapter.js at module load., \_adapter.js downloads platform binaries over HTTPS., Downloaded bytes can also arrive via DNS TXT records., \_adapter.js writes an executable temp file and chmods it., \_adapter.js launches it detached through cmd.exe or /bin/sh., Hosts and DNS domains are obfuscated by string concatenation. - **Evidence against:** package.json has no lifecycle scripts., index.js otherwise exposes a simple config loader. ## Public findings ### 1.
