A mysterious hacking group is breaching federal computer systems and gaining access to thousands of people’s personal information, Fox News reports.
The FBI issued warnings to federal agencies that the hackers, who are associated with Anonymous, may becoming more widespread.
So far, the agencies affected were the U.S. Army, Department of Energy and the Department of Health and Human Services.
The campaign has been going on for about a year and appears to be an act of retaliation for the prosecution of other hackers, Fox reported.
