Check who you got IP from
Few days ago I’ve received email from my hosting provider (where I have my VPS, used only as proxy) that they were informed by some company (let them be anonymous this time) about copyright infringement taking place on my server. At thirst I was confused, then I’ve became shocked. As I have no HTTP or FTP server on my VPS installed, I’ve thought that it got compromised. So I’ve checked logs, folders, but found nothing.
