Conficker controls 4% of globally infected PCs

IBM's security department claims that for every 25 domain names used to download malicious data on the Internet, it is under the control of the dangerous computer worm Conficker .

Holly Stewart - In charge of the X-Force security response group of the IBM Internet Security System - said the team now has enough data needed to produce a relatively accurate forecast of the number of PC is under the control of Conficker.

By scouring the network of data directly to Conficer-infected PCs to find this computer worm's P2P peer-to-peer connection path plus a number of specific techniques, X-Force has It is possible to classify infected PC variants Conficker.c.

Earlier this week, X-Force also used these techniques to identify the most infected areas Conficker.c in the world. Specifically, Asia is the area with the most PC infections Conficker.c most. Next is Europe. Meanwhile, the number of PCs infected with this worm variant in the US and Canada is relatively small.

Specifically this time IBM has determined that about 4% of the total number of maliciously infected PCs spreading malicious activities worldwide is currently under the control of the variant Conficker.c.

Tom Cross - CEO of X-Force - said that the 4% figure is not a small number if you look at the total number of maliciously infected PCs worldwide. This can be considered one of the biggest Internet threats in recent years.

In addition, X-Force also detected a fairly rapid growth in the number of infected PC addresses Conficker.c. If on Monday, only about 37,000 independent IP addresses were infected with Conficker.c, this number was up to 64,000 by Wednesday - an increase of 71%.

Cross said the increase is not yet evidence that Conficker.c is spreading widely, but it is evidence that advances in technology detect this worm variant. ' The method of detecting Conficker.c is still quite time consuming '.
