It retrieves a remote binary, saves it in a temporary directory, and executes it detached. - **Trigger:** Requiring/importing checkout-accounts-holder, including normal application startup. - **Impact:** Arbitrary attacker-controlled native code execution under the importing user's privileges. - **Evidence paths:** package.json, index.js, \_platform.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:32:12.817Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated remote binary download, temporary-file drop, and detached shell execution. - **Attack narrative:** A normal require of index.js silently loads \_platform.js. Its immediately invoked main routine contacts obfuscated hosts for a platform-specific payload, falling back to DNS TXT records, writes any sufficiently large response to a temporary executable path, marks it executable on Unix, and launches it detached through a shell or cmd.exe. - **Rationale:** This is a concrete import-time remote-payload execution chain unrelated to the documented holder interface. No install hook is required for compromise. - **Files touched:** index.js, \_platform.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, Windows Temp/dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf100-416.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf99-9b3.workers.dev, sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js imports \_platform.js at package import time., \_platform.js downloads platform binaries over HTTPS and DNS TXT fallback., \_platform.js writes payloads to /var/tmp or Windows Temp, chmods them, then spawns them detached., Remote hosts are obfuscated through string concatenation. - **Evidence against:** package.json has no lifecycle scripts., lib/telemetry.js is not imported by the public entrypoint. ## Public findings ### 1.
