Techweb looks into another part of the seedy side of the 'Net: Botnets are now engaging in turf wars.|
But the savvier botnets go the extra mile to protect their captor capital: Some actually "secure" the bot machines they have infected so no other botnets can steal them or utilize them, too. They install patches on their bots, for instance, to close the security holes and shut down open ports that are vulnerable to attack. "They are installing defenses to make sure no one else doubly infects the machine," says Paul Mockapetris, chairman and chief scientist of Nominum. "There are instances where a machine is infected, and part of that is defense against another infection."
The bottom line is the bottom line, of course: The more bots you have, the better chance you have of making money off your spam runs, identity theft efforts, etc. And bots are often used to advertise botnet services, too, touting features such as IP addresses that change every 10 minutes.
