The hidden logic can start a platform shell and exchange command/output messages with that server. - **Trigger:** Application imports the package and calls provider(serverUrl). - **Impact:** A supplied or compromised control server can execute arbitrary OS commands with the host process's privileges. - **Evidence paths:** package.json, index.js, README.md, index.d.ts - **Review source:** ai\_review - **Reviewed:** 2026-08-06T20:26:20.294Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated WebSocket-controlled shell execution. - **Attack narrative:** The exported provider function activates an obfuscated virtual-machine payload. Its embedded strings and control flow show registration to the supplied server, WebSocket command handling, platform shell spawning (cmd.exe or /bin/bash), and output/acknowledgement relay. This creates a remote-command channel not justified by the advertised health-monitoring API. - **Rationale:** Although activation is user-invoked rather than install-time, the package conceals a remote shell behind a health-client interface. The concrete command-and-control behavior warrants blocking. - **Files touched:** index.js ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js is heavily obfuscated and begins with anti-inspection text., index.js imports child\_process.spawn and embeds cmd.exe and /bin/bash shell strings., Decoded embedded program logic handles WebSocket "command" messages and command acknowledgements., provider(serverUrl) connects to a caller-supplied server, registers host data, and can relay spawned-shell output. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., README.md documents an explicit provider(serverUrl) invocation., No hard-coded network host or package-file write primitive was found. ## Public findings ### 1.
