Step-by-step for an infected WordPress site: top to find the rogue process, lsof to locate the file, chmod 000 + chattr +i to neutralize it, then dig through cron and core.

Moving the blog off GhostCMS and from harry.coffee to harry.id.

Have you heard about localization?

Deny all except some IPs Go to your domain on Cloudflare.
