AI Security Review
scanned 4mo ago · by lpm-firewall-aiThe decisive behavior is not ordinary CLI networking; it is unconsented postinstall mutation of foreign/broad AI-agent control surfaces. Under the provided policy this should be blocked even though the repo and API names appear package-aligned. Product guard normalized a concrete AI-agent control hijack publish_block to the blockable dangerous-capability shape.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
npm install -g @ubnt/cawcut
Impact
Installs external agent skills into Cursor, Claude Code, Codex, and shared skills locations, potentially changing future agent behavior.
Mechanism
postinstall invokes npx skills add for AI-agent skills
Policy narrative
On global installation, the package postinstall checks global install state, then spawns npx --yes skills add Ubiquiti-UID/flow-cawcut-skill globally for cursor, claude-code, and codex. This installs agent skills into broad AI-agent control surfaces without an explicit user command.

Decision evidence
public snapshotAI identified this as a dangerous AI-agent capability at 94.0% confidence with low false-positive risk.
Evidence for policy risk
- package.json runs postinstall: node dist/postinstall.js.
- dist/postinstall.js runs on global install and calls installCawcutSkills without user command consent.
- dist/lib/skills-install.js spawns npx --yes skills add Ubiquiti-UID/flow-cawcut-skill -g -y --skill *.
- dist/lib/skills-agents.js targets cursor, claude-code, and codex agent skill directories.
- dist/lib/bootstrap-skills.js can also auto-install missing skills during normal CLI invocation.
Evidence against
- postinstall skips local installs, CI=true, or CAWCUT_SKIP_SETUP=1.
- OAuth/API endpoints in config/products.json are package-aligned cawcut.com services.
- Credential storage is local .cawcut credentials.json with 0600 mode; no source evidence of credential exfiltration.
- Uninstall path removes named CawCut skills and local credentials.
