AI Security Review

scanned 2h ago · by lpm-firewall-ai

The package is a heavily obfuscated bulk messaging and webmail automation tool with phishing/spam-adjacent capability. No unconsented install-time compromise or remote payload execution was confirmed.

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
npm install for lifecycle scripts; user running nolimit CLI or WebSend for messaging features
Impact
Dangerous dual-use capability for spam/phishing campaigns, but no confirmed attacker exfiltration or persistence from install alone.
Mechanism
user-invoked bulk email/SMS sending, contact extraction, and webmail DOM automation
Rationale
Static source inspection supports a warning for dangerous dual-use spam/phishing automation, but not a publish block because the inspected install hooks do not perform unconsented broad control-surface mutation, payload download, credential theft, or attacker exfiltration. The high-risk behavior is package-aligned and user-invoked, though heavily obfuscated.

Decision evidence

public snapshot
AI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
  • package.json defines preinstall/postinstall and obfuscated CLI main .ad/x0.js.
  • .ad/x0.js implements bulk SMTP/SMS sending, OAuth SMTP setup, contact extraction, SOCKS/proxy and DKIM tooling.
  • src/web-panel/ws.js injects a panel into Gmail/Outlook/Yahoo and clicks Send for target lists.
  • Templates include tracking-link placeholders and attachment generators; phonebook includes carrier SMTP gateways.
Evidence against
  • scripts/preinstall.js only prompts for EULA and writes ~/.nolimit/eula.json on acceptance.
  • scripts/postinstall.js only creates a Windows nolimit.cmd shim and does not download or execute remote payloads.
  • No confirmed credential exfiltration to attacker-controlled endpoint found in inspected install hooks or web panel.
  • Risky behaviors appear user-invoked CLI/webmail features rather than import-time or install-time compromise.
