AI Security Review

scanned 4h ago · by lpm-firewall-ai

LPM blocks this version under the AI-agent control-surface policy. Installation mutates a consumer project's AI-agent instruction file without consent. The added pointer can influence subsequent agent behavior through package-supplied instructions.

Static reason

High-risk behavior combination matched malicious policy.; source fingerprint signature matched known malicious package; routed for review

Trigger

npm install as a dependency

Impact

Unconsented AI-agent control-surface hijack in the consuming project.

Mechanism

postinstall writes package-controlled agent guidance into project control files

Policy narrative

On dependency installation, the postinstall script derives the consumer project root, selects an existing CLAUDE.md or AGENTS.md (or creates AGENTS.md), and appends a marker-delimited instruction directing agents to follow this package's AGENTS.md. This is an unconsented install-time mutation of a foreign, broad AI-agent control surface.

Rationale

The package contains a concrete automatic postinstall write to consumer AI-agent instruction files. The absence of exfiltration does not remove this policy-defined control-surface attack.

Evidence

package.jsonscripts/postinstall.mjsAGENTS.mddist/index.jsCLAUDE.mdnode_modules/artefact-design-system/AGENTS.md

Decision evidence

public snapshot

AI called this Malicious at 98.0% confidence as Malware with low false-positive risk.

Evidence for policy block

package.json runs postinstall automatically.
scripts/postinstall.mjs locates consumer project root.
It appends to or creates CLAUDE.md or AGENTS.md.
Injected text directs agents to package-controlled AGENTS.md.

Evidence against

No network, shell, eval, or payload loading found.
dist/index.js is a React UI component bundle.
Font files are valid WOFF2 assets.
