The Computer Fraud and Abuse Act (CFAA) is a U.S. federal law criminalizing unauthorized access to computers and certain forms of fraud. Security teams cite CFAA in incident response when credentials are stolen or APIs are abused, relevant to payment systems holding API keys that move money.
CFAA litigation history includes disputes over “exceeding authorized access.” Practically, merchants should enforce least-privilege API keys (separate sandbox and production), monitor anomalous token/cryptogram volume, and revoke keys promptly on employee offboarding.
CFAA does not replace PCI or breach notification laws; it adds criminal and civil angles for malicious intrusion. Pair technical controls (mTLS to schemes, HMAC webhooks) with access governance.
Veliro provides audit logs and key rotation APIs to support forensic investigations if CFAA-relevant incidents occur on the merchant side. Defense in depth assumes keys will leak eventually; design blast radius accordingly.
Bug bounty and responsible disclosure policies complement CFAA deterrence by giving researchers a lawful channel; publish scope and safe harbor language alongside API key hygiene runbooks.
