Swiss Scientists Develop Algorithm to Sniff out the Source of Malware
Swiss scientists have developed an algorithm that can be used to locate spammers as well as the source of a computer virus or malware.
The algorithm finds the source by only checking a small percentage of the connections in a network, said Pedro Pinto, postdoctoral researcher at the Audiovisual Communications Laboratory of the Swiss Federal Institute of Technology (EPFL) on Monday.
If you would like to find the source of a virus, malware or spam-attack it is impossible to track the status of all nodes on the Internet, Pinto said in a telephone interview. "That would mean you would need about 1 billion sensors. And you don't want to monitor the entire Internet," he added.
Instead he and his colleagues devised an algorithm that shows that it is possible to estimate the location of the source from measurements collected by sparsely placed observers or sensors.
