Anonymous is at it again—and this time it's personal. The Daily Dot reports that on Wednesday night, the group leaked FBI search warrants related to the government's investigation of hacker group Lulzsec—and revealed that there were more agency moles in the gang than previously thought.

Remember LulzSec? The Anonymous-offshoot gang of hackers who alternately terrorized and delighted the internet in the summer of 2011 have been pretty much all rounded up. And today four Brits who were core members of the group were sentenced in the UK for their crimes.

Another couple of people suspected of being members of the hacking collectives Anonymous and LulzSec were picked up today. One was reportedly homeless, which brings up some interesting logistical questions.

If you're a hacker, you can't trust anyone. Even the fellow gamers in an Xbox forum. That's how an 18-year-old leader of the notorious hacking group Lulz Security got tripped up, according to one of his comrades.

The hacktivists of Anonymous are often dismissed as unskilled noobs. But now the Department of Homeland Security has called out Anonymous as "script kiddies" with rudimentary hacking skills. Oh no they didn't.

The 18-year-old arrested on Scotland's remote Shetland Islands for allegedly wreaking online havoc as the wisecracking spokesman for the hacking group Lulz Security was bailed out today. Jake Davis aka "Topiary" (we think!) emerged with his eyes well-shielded from the international spotlight.

Scotland Yard says they arrested the 19-year-old leader of the hacking group Lulz Security, a hacker with the nickname "Topiary," in Scotland's Shetland Islands. But the internet, goaded on by idiot vigilantes, seems to think they have the wrong guy.

British police announced today that they arrested a 19-year-old hacker in Scotland's isolated Shetland Islands who used the nickname "Topiary" online. Here's what we know about this core member of the hacking group Lulz Security, from interviews and leaked chat transcripts.

Scotland Yard says it's arrested the leader/unofficial spokesman of the notorious hacking group LulzSec, a hacker who went by the handle Topiary. The noose is about as tight as it can get around LulzSec now.

The evil, teaparty-funding Koch Brothers do not appreciate their websites being bombarded by hackers. The FBI is targeting people possibly connected to a February Anonymous attack on Koch Industries websites, including a brutal assault on their powerful bathroom tissue manufacturing arm.

The FBI investigation into the hacking collective Anonymous is still plodding along. Ten FBI agents raided three New York guys and took away their computer stuff.

The hacking group LulzSec appears to be back, with a very timely hack of Rupert Murdoch's British tabloid The Sun—the sister publication of the dead News of the World. And they warn, ominously, that they've got emails, too.

One of the favorite pastimes of hackers is attempting to expose other hackers. These attempts at "doxing," as it's called, almost always identify the wrong people. The latest victim is a Portuguese guy who's been fingered as a ringleader of the hacking groups Anonymous and Lulz Security.

This summer it seems every day brings dire news of a new data breach perpetrated by shadowy hackers. For those prone to panic, it might be enough to end in a hospital visit. But there's no need to freak out about every single attack reported by a hacker-obsessed media.

The hacking group Anonymous claims it's stolen and leaked personal emails and other documents—including "seductive girlfriend pictures"—belonging to Arizona Department of Public Safety officers. Hacker Summer continues.

The 19-year-old suspect in the Lulz Security hacking spree has been been charged with "cybercrimes," including a DDoS attack on the British Serious Organized Crime Agency, according to Sky News—no charges related to hacks in the U.S. were filed.

UK police have arrested a 19-year-old Essex man in connection with recent hacking attacks. Alas, it doesn't seem likely, as some media reports suggest, that this guy is a "mastermind" of the Lulz Security hacking group.

The swashbuckling hacking group Lulz Security says it's teaming up with fellow hacking group Anonymous to wage war on government agencies and anyone who gets in their way. Everyone: Change all your passwords to ninety-character strings of random letters and symbols!

According to a CIA spokeswoman, the Lulz Security hack attack that took down the CIA's public website for several hours yesterday was no big deal. But... what about cyberwar!

The CIA's website is down, and the hacking group Lulz Security is claiming credit on Twitter.
