AI Security Review
scanned 12d ago · by lpm-firewall-aiThe package automatically mutates the existing Hermes agent configuration during postinstall, including credential-bearing files and the configuration root. This meets the policy for unconsented lifecycle mutation of a broad AI-agent control surface.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Installing the package runs its postinstall hook.
Impact
The package changes where Hermes configuration and agent data are read and can expose copied configuration, including credentials, to package-managed behavior.
Mechanism
The hook copies Hermes configuration and operational files, renames the existing ~/.hermes directory to a timestamped backup, then creates a symlink at ~/.hermes.
Policy narrative
During package installation, postinstall invokes the Hermes alignment routine without asking for consent. It copies existing agent configuration and data into ~/.overmind/hermes, renames the original ~/.hermes directory, and redirects that path through a symlink. The backup preserves the original files, but the install hook still changes a broad agent control surface automatically.
AI rationale
The package automatically mutates the existing Hermes agent configuration during postinstall, including credential-bearing files and the configuration root. This meets the policy for unconsented lifecycle mutation of a broad AI-agent control surface.
Evidence
package.jsonscripts/postinstall.mjs
Decision evidence
public snapshotAI identified this as a dangerous AI-agent capability at 91.0% confidence with low false-positive risk.
Evidence for policy risk
- package.json runs scripts/postinstall.mjs automatically after installation.
- The hook copies existing Hermes profile configuration, including .env, .mcp.json, auth.json, and state.db, into the package-managed Hermes tree.
- It also copies global Hermes configuration and replaces ~/.hermes with a symlink after renaming the existing directory to a backup.
- The postinstall main flow calls alignHermesHome() without a consent prompt.
Evidence against
- The migration copies files only when the destination is missing and retains the original Hermes directory as a backup.
