20% of users are still indifferent to Conficker

Survey of Qualys Inc. shows that despite being warned a lot, it seems that businesses are still indifferent to Conficker. 20% of the PCs in these businesses are still completely "open to the door" of this dangerous computer worm .

Conducting a scanning test on about 300,000 PCs running this security firm's Windows operating system found the percentage of PCs installed with MS08-067 fixes - security fixes that Conficker uses to attack users - has increased significantly in the past two weeks.

20% of users are still indifferent to Conficker Picture 1 Wolfgang Kandek, Qualys' chief technology officer, said that thanks to the media's extensive news on the April 1 issue, the number of people conducting system scans has skyrocketed. ' Calculating the number of users scanning the test in April has increased more than 4 times compared to just a day earlier '.

Similar to other security vendors, Qualys also released a tool to help users detect and destroy Conficker to prevent the predicted explosion in the night of 1/4 - the pre-programmed time in source code Conficker to it. can connect to the receiving server to launch a new attack.

The rate of scanned PCs has not been installed MS08-067 bug fixes started to tend to drop sharply from April 1. Within a few days this ratio has decreased from 40% to 20%. 'The overall situation is very good,' Kandek said.

' Before April 1, the number of PCs installing MS08-067 fixes was similar to other security fixes of Microsoft. But now this ratio is much better and much higher than the average . '

But still one of the 5 Qualys scanned PCs still has not installed the MS08-067 fix. ' I don't understand why this situation still occurs. These can be old PCs, unimportant PCs or even Windows versions running on ATMs. Either way, it's hard to understand why users won't fix bugs. They have been warned a lot about Conficker's danger level .

About 5% of Qualys scanned PCs are infected at the same time with 4 different Conficker variants. Most PCs infected with Conficker are now used to distribute spam.
