Taking a cue from scientists searching for signs of extraterrestrial life and mathematicians trying to identify very large prime numbers, the agency best known for protecting presidents and other high officials is tying together its employees' desktop computers in a network designed to crack passwords that alleged criminals have used to scramble evidence of their crimes -- everything from lists of stolen credit card numbers and Social Security numbers to records of bank transfers and e-mail communications with victims and accomplices.
To date, the Secret Service has linked 4,000 of its employees' computers into the "Distributed Networking Attack" program. The effort started nearly three years ago to battle a surge in the number of cases in which savvy computer criminals have used commercial or free encryption software to safeguard stolen financial information, according to DNA program manager Al Lewis.
"We're seeing more and more cases coming in where we have to break encryption," Lewis said. "What we're finding is that criminals who use encryption usually are higher profile and higher value targets for us because it means from an evidentiary standpoint they have more to hide."
Each computer in the DNA network contributes a sliver of its processing power to the effort, allowing the entire system to continuously hammer away at numerous encryption keys at a rate of more than a million password combinations per second.
