The News Dissector blog currently has been hacked, with the home page saying “Heh !!! Unfortunately Your Site Is hacked By Minus Power Virus Coding Team.for the lack of security.”
Water World Week has an announcement, “ On Tuesday, August 16, and continuing today, our server was attacked by a virus, and the Secretariat (SIWI) has been unable to receive any email.”
So, keep those patches up to date, and do lots of backups. Having lax computer security is like leaving the back door unlocked then wondering why you got robbed. If the door is locked, they’ll probably go elsewhere instead.
