Online hacktivist group Anonymous has said that it has breached the database of IRC Federal, an IT contractor that works for the FBI and other federal agencies in the US.
Hackers have posted the information they stole from the website, including internal documents and e-mail information.
The website of IRC remained closed two days after the attack.
A IRC Federal spokesman said, "We reported it to the authorities, and otherwise we have no comment."
The FBI has not commented on the hack so far.
In a statement online, the hacker group asked the employees of the company to stop working for companies which had been "selling out their ‘skills’ to the US empire."

"If you place any value on freedom, then stop working for the oligarchy and start working against it. Stop aiding the corporations and a government which uses unethical means to corner vast amounts of wealth and proceed to flagrantly abuse their power," it said.
The statement added, "They [IRC] brag about their multi-million dollar partnership with the FBI, Army, Navy, NASA, and the Department of Justice, selling out their "skills" to the US empire. So we laid nuclear waste to their systems, owning their pathetic windows box, dropping their databases and private emails, and defaced their professional looking website.
"In their emails we found various contracts, development schematics, and internal documents for various government institutions including a proposal for the FBI to develop a "Special Identities Modernisation (SIM) Project" to "reduce terrorist and criminal activity by protecting all records associated with trusted individuals and revealing the identities of those individuals who may
pose serious risk to the United States and its allies.
"We also found fingerprinting contracts for the DOJ, biometrics development for the military, and strategy contracts for the "National Nuclear Security Administration Nuclear Weapons Complex.
"Additionally we found login info to various VPNs and several Department of Energy login access panels that we are dumping *live* complete with some URLs to live ASP file browser and upload backdoors – let’s see how long it takes for them to remove it (don’t worry we’ll keep putting it back up until they pull the box ;D)"
