- Least privilege: Review low-privileged users; remove dormant accounts and require password resets where relevant.
- Scan & logs: Check for unfamiliar admin users, modified core files, and suspicious uploads (e.g.,
wp-content/uploads). - Backups: Create a fresh backup before bulk updates; verify restore works.
