The Chinese hacking group suspected of stealing sensitive information about millions of current and former U.S. government employees has a different mission and organizational structure than the military hackers who have been accused of other U.S. data breaches, according to people familiar with the matter.

While the Chinese People's Liberation Army typically goes after defense and trade secrets, this hacking group has repeatedly accessed data that could be useful to Chinese counter-intelligence and internal stability, said two people close to the U.S. investigation.

Washington has not publicly accused Beijing of orchestrating the data breach at the U.S. Office of Personnel Management (OPM), and China has dismissed as "irresponsible and unscientific" any suggestion that it was behind the attack.

Sources told Reuters that the hackers employed a rare tool to take remote control of computers, dubbed Sakula, that was also used in the data breach at U.S. health insurer Anthem Inc disclosed this year.

The Anthem attack, in turn, has been tied to a group that security researchers said is affiliated with China's Ministry of State Security, which is focused on government stability, counter-intelligence and dissidents. The ministry could not immediately be reached for comment.

In addition, U.S. investigators believe the hackers registered the deceptively named website to try to capture employee names and passwords, in the same way that Anthem, formerly known as Wellpoint, was subverted with spurious websites such as, which used the number "1" instead of the letter "l".

Both the Anthem and OPM breaches used malicious software electronically signed as safe with a certificate stolen from DTOPTOOLZ Co, a Korean software company, the people close to the inquiry said. DTOPTOOLZ said it had no involvement in the data breaches.

The FBI did not respond to requests for comment. People familiar with its investigation said Sakula had only been seen in use by a small number of Chinese hacking teams.

"Chinese law prohibits hacking attacks and other such behaviors which damage Internet security," China's Foreign Ministry said in a statement. "The Chinese government takes resolute strong measures against any kind of hacking attack. We oppose baseless insinuations against China."
