AI Security Review
scanned 16d ago · by lpm-firewall-aiThe manifest's postinstall hook reaches code that automatically writes to multiple AI-agent configuration locations without a consent prompt. This meets the block criterion for unconsented install-time mutation of foreign or broad agent control surfaces.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review
Trigger
Installing the package through npm, which invokes its postinstall script.
Impact
The package changes files that guide AI-agent behavior across multiple tools.
Mechanism
The handler calls the IDE skill installer, which writes skill and command files and appends instructions to agent configuration.
Policy narrative
During npm installation, the postinstall handler runs the skill installer silently. That installer writes agent skills and commands and appends instructions to global Claude configuration, with corresponding writes for other agent tools. This is unconsented mutation of broad AI-agent control surfaces.
AI rationale
The manifest's postinstall hook reaches code that automatically writes to multiple AI-agent configuration locations without a consent prompt. This meets the block criterion for unconsented install-time mutation of foreign or broad agent control surfaces.
Evidence
package.jsonbin/inboost-proxy.js
Decision evidence
public snapshotAI identified this as a dangerous AI-agent capability at 98.0% confidence with low false-positive risk.
Evidence for policy risk
- The manifest runs the CLI with a postinstall hook.
- The postinstall handler automatically installs agent files without prompting.
- Installation writes skill files and appends instructions to global Claude configuration.
Evidence against
- The CLI presents itself as an AI proxy and installer for IDE integrations.
- The inspected excerpts establish agent configuration mutation, but do not establish credential theft or remote code execution.
