AI Security Review

scanned 14h ago · by lpm-firewall-ai

Importing `src/index.js` decodes and evaluates obfuscated code that includes network requests and child-process capabilities. The payload also contains a dynamically constructed loader URL.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review

Trigger

Importing the package entrypoint.

Impact

The evaluated payload can communicate with remote hosts and execute local processes; its full effects are obscured by the encoded code.

Mechanism

An embedded Base64 string is decoded and passed to `eval`; the embedded code references environment values, blockchain RPC calls, child processes, and HTTP loader requests.

Attack narrative

Importing the package entrypoint immediately evaluates an embedded Base64 payload. The source exposes environment and child-process access alongside blockchain RPC requests and requests to an HTTP loader at paths on a variable-IP host. The encoded behavior cannot be fully established from the inspected excerpt, but this is active, obfuscated network and execution behavior rather than an inert carrier.

AI rationale

The package entrypoint immediately evaluates obfuscated code with remote loader, network, and child-process indicators, supporting a malicious verdict despite the absence of install hooks. The release scripts are benign and do not explain or mitigate the entrypoint behavior.

Suspicious Lifecycle Evidence

`package.json` has no install lifecycle hook; the suspicious behavior is reached when the package entrypoint is imported.
