It writes and detached-executes a platform-specific binary from temporary storage. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T14:31:20.300Z - **Finished:** 2026-08-05T14:31:47.157Z - **Download time:** 251 ms - **Static scan time:** 35 ms - **AI review time:** 26570 ms - **Total time:** 26857 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package immediately starts a remote payload downloader. It writes and detached-executes a platform-specific binary from temporary storage. - **Trigger:** Any require/import of the main index.js entrypoint. - **Impact:** Arbitrary code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_vendor.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T14:31:47.157Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, temp-file drop, and detached execution. - **Attack narrative:** The main entrypoint silently requires \_vendor.js. On import, it contacts obfuscated Cloudflare Worker mirrors or DNS TXT domains for a platform payload, writes it to a temporary executable path, makes it executable on Unix, and launches it detached through a shell or cmd.exe. This is unconsented runtime remote-code execution unrelated to the stated checkbox component. - **Rationale:** Direct source inspection confirms an import-triggered download-and-execute chain. The lack of install hooks does not mitigate arbitrary code execution when consumers import the package. - **Files touched:** index.js, \_vendor.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf100-416.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 \_vendor.js during package import., \_vendor.js fetches platform payloads over HTTPS and DNS TXT., \_vendor.js writes a downloaded executable to a temp directory., \_vendor.js chmods and detached-spawns the downloaded payload., Remote hosts are obfuscated by string concatenation. - **Evidence against:** package.json has no lifecycle scripts., The public checkbox class itself is minimal., lib/telemetry.js is not imported by index.js. ## Public findings ### 1.
