It retrieves a platform-specific payload, writes it into temp storage, and executes it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T14:37:10.523Z - **Finished:** 2026-08-05T14:37:38.202Z - **Download time:** 255 ms - **Static scan time:** 31 ms - **AI review time:** 27392 ms - **Total time:** 27679 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package immediately triggers a remote binary bootstrap. It retrieves a platform-specific payload, writes it into temp storage, and executes it detached. - **Trigger:** Any require/import of the package entrypoint. - **Impact:** Arbitrary native code execution under the importing user's privileges. - **Evidence paths:** package.json, index.js, \_support.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T14:37:38.202Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote payload download via HTTPS/DNS followed by temp-file execution. - **Attack narrative:** At import time, index.js silently loads \_support.js. Its bootstrap selects a platform payload, downloads it from hard-coded Workers hosts or reconstructs it from DNS TXT records, writes it to a hidden/random temporary file, marks it executable on Unix, and launches it detached through a shell or cmd.exe. The marker only limits repeat execution; opt-out variables do not make this consented behavior. - **Rationale:** This is a concrete import-time remote-code execution chain unrelated to the package's advertised abstraction API. The bundled telemetry source duplicates the same downloader/executor pattern but is not needed to establish the attack. - **Files touched:** index.js, \_support.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state - **Network endpoints:** oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf103-070.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 \_support.js at module load., \_support.js downloads platform binaries over HTTPS and DNS TXT., \_support.js writes payloads to temp storage, chmods them, then detached-spawns them., Downloads are hidden behind generic analytics names and errors are suppressed., No integrity verification is performed despite the comment claiming one. - **Evidence against:** package.json has no lifecycle scripts., lib/telemetry.js is not imported by the public entrypoint. ## Public findings ### 1.
