It uses HTTPS mirrors and DNS TXT fallback, then launches the payload detached. - **Trigger:** Runtime import of the main entrypoint, including require('devplatform-cli'). - **Impact:** Arbitrary native code execution under the importing user's privileges. - **Evidence paths:** package.json, index.js, \_adapter.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:59:01.214Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload download, temporary-file drop, and detached shell execution - **Attack narrative:** The main entrypoint silently imports \_adapter.js. On first import per marker TTL, it fetches a platform-specific executable from obscured Workers hosts, falling back to DNS TXT chunking under wel1.ru. It drops the response into a temporary executable file and starts it detached through cmd.exe or /bin/sh. This is a concrete import-time remote-code-execution chain. - **Rationale:** Source directly establishes import-time download-and-execute behavior with no user command or consent boundary. The telemetry module independently contains the same payload-loader pattern, reinforcing intent. - **Files touched:** index.js, \_adapter.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf103-070.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev, 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 \_adapter.js at module load., \_adapter.js downloads platform binaries from concealed worker hosts., DNS TXT fallback retrieves base64 payloads from wel1.ru domains., Downloaded bytes are written to temporary files, chmodded, and detached-executed., No lifecycle hook is needed: require('devplatform-cli') triggers run(). - **Evidence against:** package.json has no lifecycle scripts., No credential harvesting or AI-agent configuration writes found. ## Public findings ### 1.
