Worm Conficker has spread so widely and new more dangerous variants have come out. This was told by security experts, Ben Greenbaum, Symantec's Senior Research Manager.
"The Conficker creator have strengthened the ability of it so that it can control the infected computers to connect to 50 thousand domains," said Geenbaum as quoted from CNet site.
The new worm called Conficker C is able to block the security software, block omputers' connection from the security site, and download trojans. It is also programmed to start connecting to 50 thousand domains on April 1st, to receive updates or new programs. While the previous versions contact only 250 domains.
Some large companies like Microsoft, Symantec, and others, have been trying to prevent the worm by locking the domains that have been used by the worm in distributing its updates.
Conficker is first detected in November 2008, and believed to have infected more than 15 thousand computers. A new variant, Conficker B, has been detected since a month ago. This worm has the ability to spread via network and USB by the autorun function.
Some victims were even military agencies of a country. This worm even caused an advanced fighter aircraft failed to take off.
One of the domains which has been targeted by Conficker is Southwest airline. However, spokesperson of Southwest said as of now there are no signs of damage due to the malicious program.
At the same time, security experts recommend that computer's users update their patch and anti-virus software. Microsoft offered the prize of about US $250 thousand for any information leading to the perpetrator behind Conficker
