It saves the payload in a temporary directory and executes it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-03T08:38:47.679Z - **Finished:** 2026-08-03T08:39:18.118Z - **Download time:** 505 ms - **Static scan time:** 43 ms - **AI review time:** 29890 ms - **Total time:** 30439 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package triggers a background remote binary downloader. It saves the payload in a temporary directory and executes it detached. - **Trigger:** Any runtime require/import of index.js - **Impact:** Arbitrary native code execution as the importing process user. - **Evidence paths:** package.json, index.js, \_adapter.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:39:18.118Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download with DNS fallback and detached execution - **Attack narrative:** The main entry silently imports \_adapter.js, which immediately runs. It rotates hard-coded workers.dev hosts to download a platform-specific binary, with DNS TXT/base64 retrieval as fallback. A payload over 1000 bytes is saved under a disguised temporary filename, made executable on Unix, and launched through a detached shell or cmd.exe process. - **Rationale:** This is concrete, automatically triggered remote native payload execution unrelated to the declared visual-components package. The telemetry-themed library duplicates the same downloader/launcher pattern and does not make it benign. - **Files touched:** index.js, \_adapter.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%/analytics\_state, %TEMP%/dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf100-416.workers.dev, 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 \_adapter.js at package import., \_adapter.js fetches platform binaries from workers.dev hosts., \_adapter.js reconstructs binary payloads from DNS TXT records., \_adapter.js writes, chmods, and detached-spawns downloaded binaries., No lifecycle hook is needed: requiring the main entry triggers run(). - **Evidence against:** package.json contains no npm lifecycle scripts., No credential harvesting or AI-agent control-surface writes found. ## Public findings ### 1.
