Questions before reading
No. Do not feed real payment data to a suspected compromised checkout. Use provider-approved sandbox methods, test instruments, or qualified payment-response procedures after containment.
No. It may be delivered by PHP, a database value, a checkout hook, a tag manager, a compromised extension, an external account, or a small loader that retrieves remote code.
No. It is defensive technical education. A suspected payment compromise may require coordination with payment providers, banks, insurers, legal counsel, compliance specialists, hosts, and affected parties.
The malicious delivery and access paths must be removed, required parties notified, credentials and keys handled appropriately, and the approved payment flow verified across scripts, requests, orders, webhooks, logs, and final state.
Focused, practical, and built from real WordPress recovery work.
