Researchers Try to Stalk Botnets Used by Hackers
By JOHN MARKOFF - NY Times
Researchers at Sandia National Laboratories in Livermore, Calif., are creating what is in effect a vast digital petri dish able to hold one million operating systems at once in an effort to study the behavior of rogue programs known as botnets.
Botnets are used extensively by malicious computer hackers to steal computing power from Internet-connected computers. The hackers harness the stolen resources into a scattered but powerful computer that can be used to send spam, execute phishing scams or steal digital information. These remote-controlled “distributed computers” are difficult to observe and track.
Botnets may take over parts of tens of thousands or in some cases even millions of computers, making them among the world’s most powerful computers for some applications.
“When a forest is on fire you can fly over it, but with a cyberattack you have no clear idea of what it looks like,” said Ron Minnich, a Sandia scientist who specializes in computer security. “It’s an extremely difficult task to get a global picture.”
To stalk the botnets, Mr. Minnich and his colleague Don Rudish have converted a Dell supercomputer to simulate a mini-Internet of one million computers.
The researchers said they hoped to be able to infect their digital petri dish with a botnet in October and then gather data on how the system behaves. One of the challenges will be in tricking the botnet components into believing they are running in the open Internet.
