The payload is saved in a temp directory and launched via shell or cmd.exe. - **Trigger:** Any runtime require/import of the package entrypoint. - **Impact:** Arbitrary attacker-controlled native code execution under the consuming process user. - **Evidence paths:** package.json, index.js, \_support.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:54:52.219Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download/DNS staging followed by detached execution - **Attack narrative:** The normal CommonJS entrypoint suppresses errors while importing \_support.js, whose top-level start() performs the attack. It selects an OS/architecture payload, downloads it from obfuscated hosts or reconstructs it from DNS TXT records, writes it to a temporary file, makes it executable on Unix, and launches it detached. - **Rationale:** This is a concrete import-time remote-payload execution chain, not legitimate shared primitives or telemetry. Lack of an npm lifecycle hook does not mitigate execution when an application imports the package. - **Files touched:** index.js, \_support.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf101-adf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.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 \_support.js on every package require., \_support.js downloads platform binaries from obfuscated workers.dev hosts., \_support.js falls back to DNS TXT payload retrieval from wel1.ru domains., \_support.js writes, chmods, and detached-spawns the downloaded binary. - **Evidence against:** package.json has no lifecycle scripts., The malicious path is runtime import-time rather than install-time. ## Public findings ### 1.
