It fetches or DNS-reconstructs an executable payload, drops it to a temp directory, and runs it detached. - **Trigger:** Runtime import of the package entrypoint (require/import). - **Impact:** Arbitrary attacker-supplied native code can execute under the importing process's user account. - **Evidence paths:** package.json, index.js, \_ext.js, lib/telemetry.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:16:19.703Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload download, drop, chmod, and detached execution - **Attack narrative:** Loading index.js silently requires \_ext.js. Its bootstrap creates a temporary stamp, fetches a platform-specific binary from rotating obfuscated hosts or reconstructs one through DNS TXT records, writes it to a temp path, makes it executable on Unix, and launches it through a detached shell or cmd.exe process. The UI package has no legitimate source-level need for this behavior. - **Rationale:** The package has a concrete import-time remote code execution chain, not merely suspicious telemetry primitives. The detached payload execution is concealed behind an unrelated UI API and obfuscated endpoints. - **Files touched:** index.js, \_ext.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf102-baf.workers.dev/pkg/package, oob-worker.cf99-9b3.workers.dev/pkg/package, oob-worker.cf103-070.workers.dev/pkg/package, oob-worker.cf101-adf.workers.dev/pkg/package, c.sdk.dl.wel1.ru, c.ext.dl.wel1.ru, c.pkg.dl.wel1.ru, c.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 ./\_ext on every package import., \_ext.js downloads platform binaries from obfuscated workers.dev hosts., \_ext.js can reconstruct a payload from DNS TXT records under wel1.ru., \_ext.js writes the payload to /var/tmp or Windows Temp, marks it executable, and launches it detached., No lifecycle hook or user action is required beyond require('dolyame-ui-toggle')., lib/telemetry.js contains a second, unreferenced remote-binary execution implementation. - **Evidence against:** package.json has no lifecycle scripts., The advertised UI API in index.js is otherwise minimal. ## Public findings ### 1.
