SciAgent CLI - AI Research Assistant

AI Security Review

scanned 3mo ago · by lpm-firewall-ai

The source establishes a serious unconsented staged-payload delivery and execution chain, but does not itself prove the downloaded artifacts perform malicious actions or mutate a foreign AI-agent control surface. This warrants a warning rather than a publish block under the stated boundary.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

npm installation triggers postinstall; invoking `sciagent` triggers binary selection/download and execution.

Impact

A compromised configured artifact server, registry package, or redirected download can supply code that runs as the installing user.

Mechanism

unsigned remote binary download, fallback global install, and later native process spawn

AI rationale

Decision evidence

public snapshot

AI called this Suspicious at 93.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

`package.json` runs `scripts/postinstall.js` automatically.
`scripts/postinstall.js` downloads unsigned >10MB platform binaries during postinstall.
`scripts/postinstall.js` fetches and extracts a CodeBuddy wheel, then globally installs `@tencent-ai/codebuddy-code` as fallback.
`bin/sciagent.js` re-downloads a missing or version-mismatched binary and executes it via `spawn`.
No checksum, signature, or pinned artifact digest validates downloaded executables.

Evidence against

Inspected code contains no credential harvesting or outbound file/env exfiltration.
No `eval`, `Function`, hidden process, AI-agent configuration write, or destructive broad filesystem action was found.
Writes are limited to package-owned SciAgent directories, temporary SDK files, and a global npm dependency.
