I received an email saying IMPORTANT: Do not ignore this email. This message is to inform you that the account wo7oshv4team has user id 0 (root privs). This could mean that your system was compromised (OwN3D). To be safe you should verify that your system has not been compromised. I have seen many root logins from an ip. I have delete the user account and also delete the entry from etc/passwd. Changer root password too. What else do i need to do?
