It retrieves an OS-specific executable, writes it to a temp directory, and runs it detached. - **Trigger:** Any runtime require/import of index.js. - **Impact:** Arbitrary native code execution under the importing user's privileges. - **Evidence paths:** package.json, index.js, \_ext.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:32:32.196Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download/DNS staging followed by detached execution. - **Attack narrative:** The package's main entrypoint catches and suppresses errors while importing \_ext.js. That module downloads an unverified platform-specific binary from rotating Workers hosts, or reconstructs one from DNS TXT records, saves it to a temporary path, then launches it detached through cmd.exe or /bin/sh. This is import-time arbitrary code execution, disguised with telemetry naming and opt-out variables. - **Rationale:** Direct source inspection confirms a reachable staged-payload loader and detached remote binary execution; the lack of npm lifecycle hooks does not mitigate import-time activation. - **Files touched:** /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%\\analytics\_state, %TEMP%\\dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, DNS TXT: tin.dl.well1.site, DNS TXT: tina.dl.well1.site, DNS TXT: ldr.dl.well1.site, DNS TXT: 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 \_ext.js on every package import., \_ext.js downloads platform binaries over HTTPS., \_ext.js falls back to DNS TXT payload delivery., Downloaded bytes are written to /var/tmp or Windows Temp, made executable, and spawned detached., A timestamp file suppresses repeat execution for about 6 hours. - **Evidence against:** package.json has no lifecycle scripts., Public Cards API is otherwise minimal. ## Public findings ### 1.
