Dec 31, 2025Thanks for reporting this. That alert is serious and you should treat it as a real compromise until proven otherwise.
If you did not intentionally create this file, do not ignore it. The safest steps are:
Put the site in maintenance mode or restrict access temporarily.
Backup the current state for investigation.
Remove the suspicious file /katteb-export/katteb..php and scan for similar files and recent changes.
Rotate passwords (hosting, FTP, database, WordPress admin) and regenerate any API keys.
Update WordPress core, themes, plugins, and verify file integrity.
Heads up: we are launching a 10x better Katteb on January 1, 2026, rebuilt from the ground up, with stronger infrastructure and major features like AI SEO Assistant, AI SEO Ready articles, and White Label support.
If you want, paste your hosting stack (cPanel or other) and I will give you an exact cleanup checklist and commands you can run safely.
