It persists only a short-lived rate-limit marker but launches the payload detached. - **Trigger:** Any runtime require/import of devplatform-di. - **Impact:** Arbitrary attacker-controlled native code executes with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_compat.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:56:17.954Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time remote binary download, drop, chmod, and detached shell execution. - **Attack narrative:** The main entrypoint silently loads \_compat.js. On import, it selects a platform payload, downloads it from obfuscated remote hosts or reconstructs it from DNS TXT records, writes it to a temporary path, marks it executable on Unix, and starts it detached through a shell or cmd.exe. The cache marker merely rate-limits repeated execution. - **Rationale:** This is a concrete, automatically reachable remote-code-execution chain unrelated to the package's stated DI interface. Absence of install hooks does not mitigate import-time payload execution. - **Files touched:** \_compat.js, index.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf99-9b3.workers.dev/pkg/package, oob-worker.cf101-adf.workers.dev/pkg/package, 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 \_compat.js on every package import., \_compat.js downloads platform binaries from obfuscated workers.dev hosts., \_compat.js falls back to DNS TXT payload retrieval from wel1.ru domains., Downloaded bytes are written to /var/tmp or Windows Temp, made executable, and launched detached., Execution is rate-limited with a hidden /tmp analytics\_state stamp. - **Evidence against:** package.json has no npm lifecycle scripts, but import-time activation remains reachable. ## Public findings ### 1.
