Conficker worm hasn't gone away - Network World

Conficker worm hasn't gone away, Akamai says - Network World

Variants of the Conficker worm were still active and spreading during the third quarter, accounting for much of attack traffic on the Internet, according to Akamai Technologies.

"Although mainstream and industry media coverage of the Conficker worm and its variants has dropped significantly since peaking in the second quarter, it is clear from this data that the worm (and its variants) is apparently still quite active, searching out new systems to infect," Akamai said in its State of the Internet report for the third quarter of 2009, released Thursday.

During the third quarter, 78 percent of Internet attacks observed by Akamai targeted port 445, up from 68 percent during the previous quarter. Port 445, which is used by Microsoft Directory Services, is the same port that Conficker targets, aiming to exploit a buffer overflow vulnerability in Windows and infect the targeted computer.

Most attacks originated from Russia and Brazil, which replaced China and the U.S., as the top two sources of attack traffic. Russia and Brazil accounted for 13 percent and 8.6 percent of attack traffic, respectively, Akamai said. The U.S., which came in at No. 3, accounted for 6.9 percent of attack traffic and No. 4 China accounted for 6.5 percent, it said.
