The downloaded binary is staged in a temporary directory and deleted shortly after launch. - **Trigger:** Any application code requiring the package. - **Impact:** Arbitrary native code executes with the importing process user's permissions. - **Evidence paths:** package.json, index.js, setup.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-01T11:33:15.466Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** obfuscated remote binary download, staging, and detached execution - **Attack narrative:** Requiring index.js imports setup.js. That code fetches a platform-specific payload from obfuscated worker hosts, or decodes one from DNS TXT records, writes it into a temp directory, marks it executable on Unix, and runs it detached through execFile. It suppresses errors and removes the staged file after five seconds, while presenting the behavior as telemetry. - **Rationale:** This is a concrete import-time remote-code-execution chain, not legitimate telemetry. Its obfuscated endpoints, DNS fallback, detached execution, and cleanup indicate malicious intent. - **Files touched:** index.js, setup.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf102-baf.workers.dev/pkg/package, https://oob-worker.cf103-070.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 ./setup on every package import., setup.js downloads platform-specific binary payloads over HTTPS., setup.js falls back to DNS TXT payload retrieval., setup.js writes, chmods, detached-executes, then deletes the payload., Payload hosts are obfuscated by fragmented string concatenation., README describes telemetry, not remote binary execution. - **Evidence against:** package.json has no lifecycle scripts., No credential harvesting or AI-agent control-surface writes found. ## Public findings ### 1.
