It fetches an unauthenticated payload, writes it to a temporary path, then executes it detached. - **Trigger:** Runtime import/require of devplatform-cli-spa - **Impact:** Arbitrary native code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_support.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:05:36.097Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, DNS fallback, temporary-file execution - **Attack narrative:** Requiring the package loads \_support.js, which runs immediately. It selects a platform payload path, retrieves a binary from rotating workers.dev hosts, or reconstructs one from DNS TXT records under wel1.ru. If the payload exceeds 1,000 bytes, it writes it under a disguised temporary filename, makes it executable on Unix, and launches it detached through a shell or cmd.exe. The fetched executable is neither pinned nor verified. - **Rationale:** The reachable import-time loader implements a concrete remote payload download-and-execute chain. Its telemetry labels do not change the executable behavior. - **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.cf100-416.workers.dev, oob-worker.cf999b3.workers.dev, oob-worker.cf102-baf.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 at package import time., \_support.js downloads platform binaries from Workers hosts or DNS TXT records., Downloaded bytes are written to /var/tmp or Windows Temp, chmodded, and detached-spawned., Payload sources are obfuscated with split strings and randomized mirror selection. - **Evidence against:** package.json has no lifecycle scripts., No credential or environment-value exfiltration was found in the reachable loader. ## Public findings ### 1.
