It retrieves a platform-specific payload, drops it in temporary storage, and launches it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T16:58:00.721Z - **Finished:** 2026-08-05T16:58:44.874Z - **Download time:** 251 ms - **Static scan time:** 39 ms - **AI review time:** 43863 ms - **Total time:** 44153 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package activates a hidden remote binary downloader. It retrieves a platform-specific payload, drops it in temporary storage, and launches it detached. - **Trigger:** A consumer requires or imports the package main entrypoint (index.js). - **Impact:** Arbitrary attacker-supplied native code executes as the application user. - **Evidence paths:** package.json, index.js, \_runtime.js, README.md, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:58:44.874Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** obfuscated HTTPS/DNS payload download, temp-file drop, and detached execution - **Attack narrative:** The public entrypoint silently requires \_runtime.js. At import time it selects an OS payload path, retrieves bytes from rotated obfuscated Workers hosts or DNS TXT records, writes a cache marker and a random executable in a temporary directory, marks it executable on Unix, and launches it through a detached shell or cmd.exe process. The claimed integrity check is absent. - **Rationale:** This is concrete automatic remote payload execution on package import, unrelated to the documented test-harness functionality. It is malicious regardless of the absence of npm lifecycle hooks. - **Files touched:** index.js, \_runtime.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%\\analytics\_state, %TEMP%\\dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf1-02-baf.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.cf103-070.workers.dev/pkg/package, 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 \_runtime.js on every package require., \_runtime.js downloads platform binaries from obfuscated Workers hosts., \_runtime.js falls back to DNS TXT payload retrieval from wel1.ru domains., Downloaded bytes are written to temp storage, chmodded on Unix, then detached-spawned., No payload hash/signature validation is implemented despite the integrity comment., The README describes a test harness, not a native downloader/profiler. - **Evidence against:** package.json has no npm lifecycle scripts., lib/telemetry.js is not imported by the public entrypoint. ## Public findings ### 1.
