It fetches an executable blob, stores it in a temporary directory, and launches it detached. - **Trigger:** Any Node.js require/import resolving index.js. - **Impact:** Arbitrary attacker-supplied native code executes with the importing process user's privileges. - **Evidence paths:** package.json, index.js, \_ext.js, lib/telemetry.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-02T10:23:24.613Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, temporary-file drop, and detached shell execution. - **Attack narrative:** A consumer merely requiring the advertised event-bus package executes index.js, which silently loads \_ext.js. That module selects a platform payload URL, retrieves a blob from rotating concealed hosts or DNS TXT records, writes it to a temporary path, makes it executable on Unix, and starts it detached via /bin/sh or cmd.exe. This is an unconsented remote-code-execution chain unrelated to the documented API. - **Rationale:** Source inspection confirms an import-time downloader and detached payload launcher, not just suspicious primitives. The absence of lifecycle hooks does not mitigate execution on normal import. - **Files touched:** index.js, \_ext.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf103-070.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 ./\_ext during normal package require., \_ext.js downloads OS-specific payloads from concealed workers.dev hosts., \_ext.js falls back to DNS TXT payload retrieval from well1.site domains., Downloaded data is written to /var/tmp or Windows Temp, chmodded executable, then detached-spawned., The advertised event-bus API does not require or document this native payload behavior., lib/telemetry.js contains a parallel download-to-temp-and-execute capability. - **Evidence against:** package.json has no npm lifecycle scripts., No source evidence of credential harvesting or AI-agent configuration writes. ## Public findings ### 1.
