LulzSec 'Leader' Turns on Fellow Hacktivists: Feds - Yahoo! News

Just like in a hacker movie, one of the world famous hackers is working with the feds to capture other hackers (crackers) .

Six members of the suspected computer hacking groups affiliated with Anonymous were charged -- including the suspected ring leader, who directed the entire operation from a Manhattan apartment complex -- after it was revealed one of the group's most high profile members has been working with federal authorities for months.
Hector Monsegur, a 28-year-old American believed to use the name "Sabu" on the internet, was arrested by federal agents last year and has been cooperating with law enforcement ever since, officials said. He pleaded guilty last August, a plea unsealed in federal court in Lower Manhattan today.
At least at least four of the five other members of the group were arrested recently based on information provided by Monsegur -- one in Chicago and three overseas, officials said. Each were charged with conspiracy and at least two will appear in federal court in Lower Manhattan later today.
Federal officials said they expect the arrests to seriously damage LulzSec, an underground group also known as Lulz Security, which is also an offset of the hacking group Anonymous.
Law enforcement sources told ABC News that the six people charged are allegedly among the most sophisticated hackers in the world. The FBI said motives for attacks varied -- for example an attack on credit card companies was based on the refusal by the firms to process contributions to the anti-secrecy website WikiLeaks, and another attack was simply a way of mocking internet security. The investigation began with a tip last June, officials said.
The group and Anonymous have taken credit for carrying out a number of high-profile hacking actions against companies and institutions including the CIA's website, Britain's Serious Organized Crime Agency, Japan's Sony Corp and Mexican government websites.
Last month, Anonymous published a recording of a confidential call between FBI agents and London detectives in which the law-enforcement agents discuss action they are taking against hacking.
Anonymous also claimed to be behind the electronic theft of thousands of internal documents from the private intelligence analysis firm Stratfor. In charging documents released today, federal officials said that the charged co-conspirators had stolen credit card information from Stratfor employees and clients and made some $700,000 in unauthorized charges.
Earlier this week, a Twitter account connected to Sabu continued to rant against federal agents, supposedly while he was working with them.
"The federal government is run by a bunch of f*****g cowards. Don't give in to these people. Fight back. Stay strong," a tweet from Monday reads.
While Anonymous and LulzSec by nature have no official hierarchy, the user known as Sabu was one of the most vocal and prominent members in online communities. Fox News first reported Monsegur's alleged involvement with the today's arrests.
ABC News' Jason Ryan, Mark Crudele and Lee Ferran contributed to this report.

How to Upload Large Files in PHP (in 4 steps only)

I know this info is like a core-knowledge of PHP programming, but just want to share it with my dear visitors. (Thanks to Sitepoint).

Uploading a file from a web form in PHP is easy. The online manual provides a Handling File Uploads section, and there are several articles on sitepoint.com, including How To Handle File Uploads With PHP by Kevin Yank.

One of the most popular uses is image uploads. Your users can submit photographs from a form without resorting to FTP or other convoluted methods. HTML5 and Flash also permit drag and drop, so the operation is likely to become easier as browsers evolve.
This is where the problems can begin. Camera manufacturers continually brag that they have a larger set of megapixels than their competitors. It’s all rubbish, of course — unless you’re a professional photographer or need to print extremely large images, anything over 4MP is fairly pointless and lens quality is much more important. However, even low-end compacts have 12MP and mobile phones have more than 5MP. The result is that a typical snapshot can easily be 6MB in size.

By default, PHP permits a maximum file upload of 2MB. You can ask users to resize their images before uploading but let’s face it: they won’t. Fortunately, we can increase the limit when necessary.

Two PHP configuration options control the maximum upload size: upload_max_filesize and post_max_size. Both can be set to, say, “10M” for 10 megabyte file sizes.
However, you also need to consider the time it takes to complete an upload. PHP scripts normally time-out after 30 seconds, but a 10MB file would take at least 3 minutes to upload on a healthy broadband connection (remember that upload speeds are typically five times slower than download speeds). In addition, manipulating or saving an uploaded image may also cause script time-outs. We therefore need to set PHP’s max_input_time and max_execution_time to something like 300 (5 minutes specified in seconds).

End Piracy, Not Liberty by Google

Seems like the American government wants to land a big hammer on the web.

Millions of Americans oppose SOPA and PIPA because these bills would censor the Internet and slow economic growth in the U.S.

Two bills before Congress, known as the Protect IP Act (PIPA) in the Senate and the Stop Online Piracy Act (SOPA) in the House, would censor the Web and impose harmful regulations on American business. Millions of Internet users and entrepreneurs already oppose SOPA and PIPA.
The Senate will begin voting on January 24th. Please let them know how you feel. Sign this petition urging Congress to vote NO on PIPA and SOPA before it is too late.
Chart: “Congress, Can You Hear Us?”
