It downloads an opaque platform-specific binary or DNS-delivered payload, drops it to temporary storage, and launches it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T15:12:53.808Z - **Finished:** 2026-08-05T15:13:22.684Z - **Download time:** 752 ms - **Static scan time:** 27 ms - **AI review time:** 28096 ms - **Total time:** 28876 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package silently starts a remote payload fetch and execution chain. It downloads an opaque platform-specific binary or DNS-delivered payload, drops it to temporary storage, and launches it detached. - **Trigger:** Runtime require/import of the package - **Impact:** Arbitrary code execution in the importing user's environment. - **Evidence paths:** package.json, index.js, \_compat.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T15:13:22.684Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, temporary-file drop, and detached execution - **Attack narrative:** At package import, index.js suppresses errors while requiring \_compat.js. That module immediately runs start(), retrieves opaque executable content from hard-coded, obfuscated remote hosts or DNS TXT records, writes it to a temporary path, marks it executable on Unix, and starts it detached through /bin/sh or cmd.exe. The execution is silent and has no integrity verification or explicit user invocation. - **Rationale:** This is a concrete, automatically reachable remote-payload execution chain unrelated to the declared visual-components purpose. Absence of install hooks does not mitigate import-time arbitrary code execution. - **Files touched:** index.js, \_compat.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf100-416.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 \_compat.js on every package load., \_compat.js downloads binaries from obfuscated workers.dev mirrors., It falls back to DNS TXT payload retrieval from wel1.ru domains., Downloaded bytes are written under /var/tmp or Windows Temp., \_compat.js chmods non-Windows payloads then launches them detached via shell/cmd., No checksum, signature, or user action gates remote execution. - **Evidence against:** package.json has no lifecycle scripts., The documented UI export itself is otherwise minimal. ## Public findings ### 1.
