Stolen FBI data reveals employees’ roles in intelligence and surveillance

Data stolen in a major hacking group’s alleged intrusion into FBI systems is believed to contain personal information on hundreds of FBI intelligence analysts and other employees involved in clandestine intelligence-gathering and surveillance, according to two people familiar with the matter.

The analysts focus on myriad subject areas like Russia, China, Hezbollah and cartel-related intelligence, said the people, who spoke on the condition of anonymity because the exposures are sensitive. The employees’ roles only offer a small picture of their duties, but may still help outsiders identify people working in sensitive parts of the bureau.

ShinyHunters claimed responsibility for the breach Monday, threatening to release what it described as two to three terabytes of FBI employee data unless the bureau retracted a public warning about its tactics within a week.
