FBI arrests 16 Anons across US; UK police pick up LulzSec member

The FBI has made a series of raids at addresses across the US and arrested 16 people accused of participating in Anonymous-branded cyberattacks. Arrests were made in Alabama, Arizona, California, Colorado, the District of Columbia, Florida, Massachusetts, Nevada, New Jersey, New Mexico, and Ohio, with further raids and equipment seizures conducted in New York.

14 of those arrested have been charged with conspiring with others to damage computer systems belonging to PayPal. PayPal was the victim of a distributed denial of service attack performed by Anonymous after the site blocked the ability to donate money to WikiLeaks, an action named "Operation Avenge Assange." The defendents range in age from 20 to 42 years old, with 11 males and two females; the 14th defendent has had his or her name withheld.
Separately, a 21-year-old man was arrested for breaking into the InfraGard Web site, tweeting about what he did, and providing instructions so that others could also break in.

Finally, another 21-year-old man was arrested for stealing confidential information from AT&T's systems while working as a customer support contractor. This is the data that was published as part of LulzSec's retirementfrom the public eye.
The statement issued by the Department of Justice says that in concert with the arrests in the US, one arrested was made in the UK, and four in the Netherlands.

Fox News is reporting that the arrest in the UK was of an unnamed 16-year-old whose online handle is tflow. tflow was prominent within Anonymous' denial of service and hacking operations, and a member of LulzSec too.

Prior to news of tflow's arrest, the handful of people behind breakaway Anonymous splinter group LulzSec—which yesterday came out of retirement to break into News International's servers—said on their IRC channel that they are unaffected by the arrests and raids. Members of the group have speculated that the DoS participants are being targeted because they're readily traced, especially if they use the LOIC tool that Anonymous has often used to perform such attacks. Typical usage of this tool does nothing to mask identities, making it relatively easy to track down its users. LulzSec members, in contrast, have used software such as Tor and anonymous VPN connections to mask their identities.

If tflow has indeed been arrested, he would be the first member of LulzSec to be apprehended; his arrest might also indicate that LulzSec wasn't as anonymous as it thought it was.
