The Circuit: U.K. arrests hacker, Senate Judiciary turns to cyber security, LightSquared has GPS fix

LEADING THE DAY: In London, the Metropolitan Police confirmed they have arrested a 19 year-old British man in connection with denial-of-service attacks against “a number of international businesses and intelligence agencies by what is believed to be the same hacking group.”

The release says the Metropolitan Police worked with the FBI and the local Essex police on the arrest. It is not clear whether the man arrested is connected to either the LulzSec or Anonymous hacking groups. The FBI did not immediately respond to a request for comment.

The news comes as a document posted on the site PasteBin suggests that LulzSec might have obtained the records of the entire U.K. census, The Next Web reported.

The group has not yet officially confirmed the hack on its Twitter feed — which has acted as its most official channel of communication — but a release on the open site is in the style of the hacker group.

Senate Judiciary to address cybersecurity: The Senate Judiciary Committee will take up the issue of cybersecurity today in its crime and terrorism subcommittee hearing. Deputy attorney general James Baker of the Justice Department, deputy undersecretary Greg Schaffer of Homeland Security and NIST senior policy adviser Ari Schwartz will speak before the panel. Rep. Jim Langevin (D-R.I.), who recently introduced cyber security legislation in the House, will also testify, The Hill reported.

LightSquared cuts back: LightSquared announced Monday that it has a solution to the interference issues it faces with the Global Positioning System. In a release the company said that it will begin developing a lower block of spectrum to deploy its ground and satellite broadband network. The company will also reduce the power of its base stations by 50 percent, returning LightSquared to the power it was authorized to use in 2005.

Dropbox security lapse draws ire: Dropbox, the Web-based file storage site, is facing criticism from users after reporting that it suffered a security lapse on Monday that allowed for a small percentage of user accounts to be accessed with incorrect passwords. The lapse lasted for four hours.

Security researcher Chris Soghoian first drew attention to the lapse Monday, based on an e-mail exchange with a tipster.

Groupon answers critics: Groupon responded to backlash over its initial public offering with a snarky blog post kept in check by the enforced “quiet period” that follows a company filing to go public.

The company addressed criticism from the media and industry analysts that its IPO is overblown by listing “hazing rituals” a company can expect after filing its S-1 paperwork.

These include, “Wait until the company is sleeping to smear scream-activated bees on its face. Lesson Learned: Don’t believe your company’s own ‘buzz.’”
