And now, British police have made some arrests.

Thursday’s capture of two young men believed to have been involved in the theft and online publication of some 60,000 confidential emails from HBGary Federal is part of an ongoing investigation into computer break-ins and distributed denial of service attacks by hacker collectives Anonymous and LulzSec.

The HBGary data breach exposed dirty deeds and the CEO of the company subsidiary that chased government contracts in disgrace.

That CEO, Aaron Barr, stirred up Anonymous by bragging how his company had infiltrated the group by using, among other things, . Feeling slighted, Anonymous hacked into his personal accounts and his company's servers, from which they "liberated" thousands of emails.

Some of those emails exposed some embarrassing activity in which the company was involved. For example, an effort to launch a "dirty tricks" campaign to discredit opponents of the U.S. Chamber of Commerce was revealed. That prompted one member of Congress to call for an investigation into the matter.
