Tracking Cyberspies Through the Web Wilderness

[groovedaddy]

For old-fashioned detectives, the problem was always acquiring information. For the cybersleuth, hunting evidence in the data tangle of the Internet, the problem is different.

“The holy grail is how can you distinguish between information which is garbage and information which is valuable?” said Rafal Rohozinski, a University of Cambridge-trained social scientist involved in computer security issues.

Beginning eight years ago he co-founded two groups, Information Warfare Monitor and Citizen Lab, which both have headquarters at the University of Toronto, with Ronald Deibert, a University of Toronto political scientist. The groups pursue that grail and strive to put investigative tools normally reserved for law enforcement agencies and computer security investigators at the service of groups that do not have such resources.

“We thought that civil society groups lacked an intelligence capacity,” Dr. Deibert said.

They have had some important successes. Last year Nart Villeneuve, 34, an international relations researcher who works for the two groups, found that a Chinese version of Skype software was being used for eavesdropping by one of China’s major wireless carriers, probably on behalf of Chinese government law enforcement agencies.
