October 2, 2007 at 22:52Large botnets are broken into smaller
Researchers at F-Secure report that cybercriminals are reducing the size of their botnets in order to make it difficult for companies specializing in information security software to monitor and hinder the operation of botnets.
Computers infected with the virus become so-called "Zombies" in a botnet - a network that is used to send spam and to carry out attacks on other machines. The army of zombie cars can be controlled remotely, and, as a rule, their creators usually try to create the largest botnet for DoS attacks to order.
However, researchers at the anti-virus company F-Secure noticed that large botnets are broken down into smaller ones, since the creation of large botnets does not increase the profit of cybercriminals. Now, of course, the old large botnets continue to work, but the virus writers who are creating the botnets at the moment do not try to make them large, since one large botnet does not give more money than a bunch of small ones.
In addition, cybercriminals simply began to fear that at one point the central management server of such a large botnet would fall and the entire network would be lost.
Another factor highlighted by F-Secure is that virus writers have become more lazy (does this also concern other encoders?) And do not try to create non-standard, “elusive” antivirus software viruses.
