It writes and detached-executes an unverified payload. - **Trigger:** Any require/import of boxy-client-loader, including normal application startup. - **Impact:** Arbitrary native code execution as the importing process user. - **Evidence paths:** package.json, index.js, \_platform.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T13:12:32.747Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time remote payload download, drop, chmod, and detached execution. - **Attack narrative:** Normal import of index.js silently loads \_platform.js. That module fetches a platform-specific payload from obfuscated Workers hosts or reconstructs one from DNS TXT records, writes it into a temporary directory, marks it executable on Unix, and launches it detached through a shell or cmd.exe. - **Rationale:** This is a concrete import-time remote-code-execution chain with no integrity validation or user action beyond loading the package. The unused telemetry module contains a substantially similar payload-loader design, reinforcing intent. - **Files touched:** /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%\\analytics\_state, %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.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 \_platform at module load., \_platform.js downloads platform payloads over HTTPS., \_platform.js falls back to DNS TXT base64 payload delivery., Downloaded bytes are written to /var/tmp or Temp, made executable, and spawned detached., Hosts and fallback domains are obfuscated by string concatenation. - **Evidence against:** package.json contains no lifecycle scripts., No AI-agent configuration or credential harvesting was found. ## Public findings ### 1.
