During the last few weeks I seem to be getting less and less SPAM in my e-mail, and this you would think is good. But when it infact get replaced by viruses it is not, especially not since the viruses are much larger per e-mail than regular SPAM e-mails. It all started like an ordinary virus with the latter "Bagle.A" on January the 18th... fast forwarding to the current day we have "Bagle.S", yes that is 20 versions of the same Virus in 2 months! I keep track of these viruses via F-Secure's Weblog, where F-Secure antivirus staff post details on the latest viruses as they find them. These viruses install backdoors that are used for sending SPAM from the affected computers, this backdoor allows the virus writers full control over infected PC's, they can update their viruses and install software on those computers... There have also been a new virus just released that works similarly to the old Slammer worm, this one is called Witty but only infects computers with the Black ICE software. ISS Advisories. It would seem that this indeed is starting out as the year of the Superworm.
