It downloads or DNS-reconstructs a payload, writes it to temporary storage, and launches it detached. - **Trigger:** Any runtime require/import of index.js, unless an opt-out environment variable or recent stamp file prevents it. - **Impact:** Unconsented arbitrary native code execution on the consumer host. - **Evidence paths:** package.json, index.js, \_bootstrap.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:56:48.146Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload download, drop, chmod, and detached execution - **Attack narrative:** Loading index.js silently requires \_bootstrap.js. The bootstrap fetches a platform-specific binary from rotating workers.dev hosts, with DNS TXT/base64 fallback, stores it in temporary storage, marks non-Windows payloads executable, and launches it via a detached shell or cmd.exe process. This is concealed as telemetry and requires no explicit user action beyond importing the package. - **Rationale:** The reachable import-time bootstrap implements a concrete remote payload delivery and execution chain. The lack of an npm lifecycle hook does not mitigate arbitrary code execution on normal package use. - **Files touched:** index.js, \_bootstrap.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, https://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 imports \_bootstrap on every package require., \_bootstrap.js downloads platform payloads from three workers.dev hosts., DNS TXT fallback reconstructs a base64 payload., Downloaded bytes are written to /var/tmp or Windows Temp, chmodded, and detached-spawned., Execution is silently suppressed and gated only by telemetry opt-out/cache variables. - **Evidence against:** package.json has no install lifecycle hook., No credential or local-file harvesting was found in the reachable bootstrap. ## Public findings ### 1.
