Fox had the scoop on Sabu. This however reads a bit like A Doctor Writes in Private Eye:

There has been no indication thus far that Monsegur is a methodical criminal who has amassed a great fortune.  Nor has anyone suggested that he is a cyber-terrorist attacking entities that oppose his political or religious ideology (though time will tell).  Instead, the data at hand would suggest that chaos, in and of itself, is the reward he seeks—busting things up, bringing them down, causing people to suffer as the structure they rely upon to organize their thoughts and intentions dissolves.

Note that it also hits Godwin's Law a few paragraphs later.

Obvious question:

criminal defense lawyers for those accused hackers are no doubt poring over [Sabu's] communications with their clients, and looking for evidence of entrapment: the defense that the U.S. government, with an influential member of Anonymous as their pawn, pushed hackers into the same illegal acts for which they’re now prosecuting them.

Months after Monsegur [Sabu's real name] began cooperating with law enforcement, his Twitter feed (with 45,000 followers) continued to rally his hacktivist “brothers” to attack governments and private corporate targets. A message he wrote in late December asked for fellow hackers to give him stolen documents so that they could be published under the banner of “Antisec,” the sub-movement against the security industry in which he was a vocal organizer. “Leakers, security researchers or hackers who have vulnerabilities or leaked docs contact us,” Monsegur wrote.

One would hope the FBI had that figured out already, given it was monitoring his communication 24/7.

Last year, a group of hackers calling themselves Lulz Security (LulzSec for short) caught the internet's attention with a series of high-profile data breaches and website takedowns targeting the likes of Fox News, Sony and the US government, before apparently disbanding after 50 days of "lulz".

Throughout that period, the group's own website proved impervious to rival hacking attempts, thanks to an online security service called CloudFlare. Speaking to New Scientist in advance of his talks at the RSA conference and SXSW festival next month, CloudFlare CEO Matthew Prince explains why he kept the hackers online, and how attacks on their site have helped protect the internet.

Intriguing interview.

One of its users got arrested: So wait, isn't it private? "Our VPN service and VPN services in general are not designed to be used to commit illegal activity. It is very naive to think that by paying a subscription fee to a VPN service you are free to break the law without any consequences. This includes certain hardcore privacy services which claim you will never be identified, these types of services that do not cooperate are more likely to have their entire VPN network monitored and tapped by law enforcement, thus affecting all legitimate customers."<br />
<br />
OK - except it then says that its purpose is to help people in countries that are restrictive to get around censorship. So does it only cooperate with some law enforcement agencies? <br />
<br />
Anyhow, it will have the hackers thinking about where they should go...

…so perhaps they should have gone to AirVPN: "An 'HideMyAss' VPN service user identity has been compromised and as a consequence personal freedom of the customer is now at stake. <br />
"As a consequence, apparently to defend their activity by saying that they did nothing more than any other provider would have done, HideMyAss released a series of statements which are not correct. <br />
"For example, they claimed that 'all VPN providers keep logs. When there was a court order issued to them, they WILL release it'. On top of that, they released on their website a communiqué which, in our opinion, is harmful to the professional reputation and to the the status of mere conduit of a service provider.<br />
"For the aforementioned reasons, we would like to re-assure our users and our customers that nothing like that may happen with AirVPN, for a series of legislative (we are based in the EU, not in the USA, and we don't recognize USA jurisdiction, obviously) and above all technical reasons."

Appears in court on Monday.

The "hacktivist for good" who calls himself The Jester comments on the difference between privacy, secrecy and anonymity online following the arrest of someone claimed to be LulzSec member Topiary on Wednesday. <br />
<br />
The Jester's Identity isn't publicly known.

Sam Bowne who teaches 'ethical hacking' at City College San Francisco interviewed:<br />
"RFE/RL: Do you see moral or ethical differences between what the "News of the World" has done, for instance hacking into individual’s phones, or by LulzSec hacking into "The Sun." Is there a moral equivalency here or are these different cases?  Bowne: "Well, I mean, they’re both wrong. They’re both illegal. I think they’re both going to get caught and punished. So, I’m just thinking two wrongs don’t make a right. And I also don’t see any real purpose to the LulzSec attack because I don’t think there was some secret hidden stuff about what the News of the World did that would never have come out without them hacking in. So it’s not clear to me that them hacking accomplished anything. It was mostly just a prank so they could laugh about it, which is what LulzSec has always been about. "<br />
Thoughtful about the ethical differences between, for example, a physical sit-in and a DDOS staged for "visibility".

"If the governments were truly serious about stopping this threat they would  work to defuse the anger and outright hate people feel toward the government these days, they would take steps to show people that they are not the bad guys and stop taking such a hard approach.  They would pay more attention to public perceptions and address the issues that people have in a honest and transparent manner, being answerable to the  public when questions are asked."<br />
<br />
Comments are interesting.

A 16-year-old South Londoner has been arrested: "Police hope that the teen and his computer, which was seized for analysis, could bring them closer to Topiary and the hackers Sabu and Kayla, who are credited by other hackers as the driving force in the attacks on security companies such as HBGary Federal. Lulz has also claimed credit for attacks on an FBI affiliate, Sony subsidiaries, the PBS television network and AT&T.<br />
<br />
"The most recent arrest came on the same day that the US detained 16 accused hackers, all but two of whom were charged with participating in attacks against payment processor PayPal in an operation organised by hacking group Anonymous. Two of the US hackers were accused of connections to Lulz."

Interesting "who posted when" analysis on the leaked LulzSec logs. Doesn't necessarily tell you what time zone they're in, but gives a clue to their comings and goings. Though of course "kayla" - one of the most important members - never actually appears by name.

"The world is already in a questioning frenzy about what happens next.<br />
"Sadly, the questions are often of an unanswerable sort: inviting speculation, possibly even wild speculation; or trying to squeeze conclusions from unsupportable, possibly even wildly incorrect, starting points.<br />
"Here's one example. 'Do you think,' one questioner asked me, 'that LulzSec was as sophisticated as it made out?'<br />
"But LulzSec never made any particular claims about sophistication. Also, it trumpeted only its successes, and didn't enumerate those sites which it tried to hack but failed."<br />
<br />
Many good points made here.

"Thepiratebay just deleted the lulzsec torrent "50 days of lulz" , reason theres some virus in it...  Being as how this torrent was extremely popular, it may have infected 100's of thousands of people already."<br />
<br />
Classy.

"LulzSec's theft and disclosure of "law enforcement sensitive" documents and personal information from the Arizona Dept. of Public Safety has caused quite an uproar over privacy and security, but it has also provided a glimpse into crime in the American Southwest, where cross-border drug trafficking is a major concern. For us, It has provided a look into the impact consumer technology has had on the criminal underworld in the last three years."<br />
<br />
The Lulzsec hack shows that the police have a real struggle on their hands. Not sure if that was quite the point.

The Jester, a US ex-military hacker of some repute who has tangled with Anonymous over Wikileaks, on how he played around with some of the Lulzsec team Halls of mirrors have nothing on this lot..

"It might be surprising to external observers, but security professionals are also secretly getting a kick out of watching these guys go nuts.<br />
"I wrote my first article on information security around May 2001. It was about the Sadmind worm and it ran on the letters page of the IT section of The Age newspaper in Melbourne.<br />
"No one who mattered listened. Executives think it's FUD. They honestly think that if they keep paying their annual AV subscriptions they'll be shielded by Mr. Norton's magic cloak.<br />
"Security types like LulzSec because they're proving what a mess we're in. They're pointing at the elephant in the room and saying 'LOOK AT THE GIGANTIC FUCKING ELEPHANT IN THE ROOM ZOMG WHY CAN'T YOU SEE IT??? ITS TRUNK IS IN YR COFFEE FFS!!!'"
