A gang of 3 hackers were caught and have now been charged with conspiring to hack government computers.
A Wired story discusses the different hacks that occured:
1. gang is accused of using SQL-injection hacks and other methods to gain access to various systems including ones belonging to the U.S. National Geospatial Intelligence Agency
the most interesting point is how they went about doing it:
first a member scanned Internet websites for security vulnerabilities on protected computers, and especially to government, military and critical infrastructure sites.
Second they exploited the vulnerability by using SQL injection, and obtained the database schema.
Third, a member then saved the data
Fourth, upload the data to cloud storage websites – placing the data for public to see.
Fifth, they then claimed credit for the hack
Some websites were shutdown in order to fix the problems.
This is the court document on the Wired site.
