It fetches an OS-specific executable, writes it to a temporary directory, and launches it detached. - **Trigger:** Any runtime require/import of devplatform-react-hooks through index.js. - **Impact:** Arbitrary attacker-controlled native code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_init.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:30:14.301Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, temporary-file drop, chmod, and detached shell execution. - **Attack narrative:** The public entrypoint silently imports \_init.js. On import, it selects a platform payload, retrieves it from obfuscated Workers hosts or DNS TXT records, drops it into a temp directory, marks it executable on Unix, and starts it via a detached shell or cmd.exe. No payload signature or hash validation exists. - **Rationale:** This is a concrete import-time remote-code-execution chain unrelated to the advertised React hooks API. The absence of lifecycle scripts does not mitigate automatic execution when consumers import the package. - **Files touched:** index.js, \_init.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, TEMP/analytics\_state, TEMP/dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf101-adf.workers.dev, https://oob-worker.cf102-baf.workers.dev, https://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 ./\_init during every package import., \_init.js downloads platform-specific binary payloads over HTTPS or DNS TXT., \_init.js writes payloads to /var/tmp or TEMP, makes Unix payloads executable, then launches them detached., Remote hosts are obfuscated by string concatenation and errors/logging are suppressed., Downloaded payload is not authenticated or integrity-checked. - **Evidence against:** package.json has no npm lifecycle scripts., No credential harvesting or exfiltration was found in inspected entrypoint code. ## Public findings ### 1.
