It somehow seems this summer has been a period of floating between extremes. We’ve had our share of vision in June and a good relax moment in July. August appeared as a pay back time for most unprotected users…Threats rising altogether and smashing computer systems worldwide, in very little time, which gives a lot to talk about.



The July issue of Evil Top Ten was almost entirely dedicated to a warning related to the Microsoft DCOM RPC vulnerability, more specifically to the threat it presented as to an imminent worm outbreak, exploiting the already famous breach…And it happened. Msblast (Blaster or Lovsan) was a rather expected threat: we announced the breach to everybody who wanted to listen, we knew it, Microsoft admitted it and released the patch urgently and many of us passed through this untouched. This harsh attack against Microsoft was rather direct and customized; the virus included a string entirely dedicated to Bill Gates: billy gates why do you make this possible? Stop making money and fix your software!! In only 3 weeks, Blaster got to the 3rd position in the August Evil Top Ten and that is a major fact: a virus that should have been smothered before reaching a significant level…

Moving on to the number 2 evil entry for this month: Sobig.F, another level up in the Sobig evergreen series…Most of Windows users are quite familiar with Sobig.F potential and behavior, as these were the precise elements that made it so famous in so little time. Spreading is a blunt understatement for what Sobig.F showed possible: most multiplied virus in the shortest period in the entire history of computer issues. It actually achieves in turning a computer into a sluggish machine, reinventing somehow the principles of spamming…Amazing evolution for the Sobig saga: every new creature brought some fresh features, in an increasing threat manner. Excepting the A version, last 5 have enclosed the automatic deactivation routine. In the specific case of Sobig.F, we are to bear its ugly shape until September 10th, when it finally goes to sleep. The remaining logical question would be: what’s next? Getting used to such serial outbreaks doesn’t make things any easier, but it might somehow improve our pro-active tendencies. Somehow, I must declare my doubts in whatever relates to the previous statement: the thing got to its’ 6th live performance and it still hit users like out of the blue…

Anyway, something tells me we haven’t seen the last of Sobig yet…That can perhaps be discussed in our September issue.

Until then, BitDefender prefers to keep its users still curious and perfectly protected.
Note: BitDefender users were protected since the very beginning against the threats described above. Moreover, BitDefender experts were among the first to release antidote tools, freely available on the Internet.
