The shim fetches a platform-specific binary, including through DNS TXT fallback, then executes it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-02T14:25:38.461Z - **Finished:** 2026-08-02T14:26:31.734Z - **Download time:** 508 ms - **Static scan time:** 64 ms - **AI review time:** 52700 ms - **Total time:** 53273 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package immediately loads \_shim.js. The shim fetches a platform-specific binary, including through DNS TXT fallback, then executes it detached. - **Trigger:** Runtime require/import of the main index.js entrypoint. - **Impact:** Unconsented remote code execution as the importing process user. - **Evidence paths:** package.json, index.js, \_shim.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-02T14:26:31.734Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, temp-file staging, and detached execution. - **Attack narrative:** The main entrypoint silently requires \_shim.js. On import, it avoids opt-out environments, creates a marker, downloads a platform-specific payload from obfuscated endpoints or reconstructs it from DNS TXT records, writes it to temporary storage, marks Unix payloads executable, and launches it through a detached shell or cmd.exe process. - **Rationale:** This is a concrete import-time staged-payload and remote-execution chain unrelated to the declared UI toolkit. The absence of lifecycle hooks does not mitigate execution through the normal package entrypoint. - **Files touched:** index.js, \_shim.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\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 \_shim.js on every package import., \_shim.js downloads binaries from obfuscated workers.dev hosts., \_shim.js falls back to DNS TXT payload delivery., \_shim.js writes payloads to temp storage, chmods them, and detached-spawns them. - **Evidence against:** package.json contains no lifecycle scripts., No credential harvesting or AI-agent control-surface writes found. ## Public findings ### 1.
