Cyber attacks on dozens of American companies appear to have originated in an area of Shanghai that houses a Chinese military unit. That's according to a report out Tuesday from a U.S. cybersecurity company which says the group behind the attacks is the most prolific it's ever followed.

A US company has accused a Chinese military intelligence unit in Shanghai of conducting a huge cyber espionage campaign against western companies, in the most specific allegations that the People’s Liberation Army sponsors hacking.

Mandiant, a Washington-based cyber security group, said APT1 – a group of hackers it observed attacking at least 141 companies in the US and 15 other countries over the past seven years – was in fact a PLA group called Unit 61398.
