JPMorgan Chase's own investigators have found clues that a global network of computers available for hire by sophisticated criminals was used to reroute data stolen from the bank to a major Russian city, according to people familiar with the probe.
Bloomberg News reports that like street magicians using sleight of hand, the hackers tapped computers from Latin America to Asia to send commands and obscure their identity while ferrying malicious traffic past one of the most heavily guarded networks on Wall Street.
Bank investigators working nearly around the clock have identified what they believe to be the assault’s staging ground, called a 'bulletproof' hosting platform because of its resilience to other attackers and to law enforcement, according to one of the people, who requested anonymity because of the continuing investigation. The constellation of computers was used in previous hacking attacks and is now being tapped by professional cybercriminals operating out of Eastern Europe to target banks.
The bank’s investigators are only part of a larger group in the U.S. that includes the Federal Bureau of Investigation and the National Security Agency trying to trace the origin of the computer assault.
