Where persistence hides.

WHY THIS MATTERS

Attackers use scheduled tasks to reinstate themselves after cleanup.

That is why sites are cleaned and compromised again days later.

WHAT TO CHECK

Every cron job in cPanel Scheduled tasks within your application

WHAT A MALICIOUS JOB LOOKS LIKE

A command downloading and running something An obscure file path Obfuscated content A schedule you did not set

WHAT TO DO

Remove anything you did not create.

If unsure, record it and ask us before removing.

FOR WORDPRESS

Scheduled events within the application can also be used.

A cron viewer plugin lists them.

Look for anything unfamiliar.

WHAT ELSE TO CHECK

Startup files Anything set to run automatically

WHY THIS STEP IS SKIPPED

Most cleanup guidance concentrates on files.

That is why cleanups fail.

WHAT TO DO AFTERWARDS

Recreate your legitimate cron jobs, if you removed them.
