A hacker-turned-government-informant was sentenced to time served for his help in thwarting more than 300 cyberattacks on the government and large corporations while in prison.
The Los Angeles Times reports Hector Xavier Monsegur was sentenced and ordered to pay a $1,200 fine Tuesday after spending just seven months in jail. The U.S. attorney in Manhattan called him "an extremely valuable and productive cooperator."
The New York Times says Monsegur spent May to December of 2012 in jail, but was released on bail. Federal guidelines suggest he could have been sentenced 21 to 26 years in prison.

Wired says Monsegur would then take that information and provide it to the FBI. In all, the publication reports Monsegur helped expose eight Anonymous hackers.
The Washington Post reports Jeremy Hammond is one of those. Hammond was sentenced to ten years for allegedly hacking government agencies and businesses as well as uploading 60,000 credit card numbers online.
Anonymous voiced its support for Hammond on Twitter Tuesday.
Prosecutors say Monsegur's help prevented the online theft of millions of dollars from the federal government, the military, Congress, NASA, a television network and a video game manufacturer, among others.
