A bunch of people are currently camped out in a park near Wall Street to protest, well, it's not exactly clear what they're protesting. Corporations and stuff? Also, Anonymous is involved. Here's a guide to what's going on.

Online attack mob Anonymous famously built software enabling basically anyone to launch a denial of service attack and help crash a website. Now the group has point-and-shoot software for hijacking Twitter threads, too. Is nothing sacred?

Hackers launched a denial of service (DDOS) attack on TPM on Friday, knocking the site off-line. TPM had posted mugshots of 14 individuals the FBI said are connected to the 'hactivist' group Anonymous earlier in the day.

In July, the FBI arrested 16 alleged members of the hacktivist collective Anonymous, which has claimed credit for attacks on PayPal, Visa and Mastercard. Talking Points Memo obtained most of their mugshots. They were unfortunately unable to wear their trademark Guy Fawkes mask while being booked.

Surprise: A 16-year-old female hacking prodigy might actually be a couple of dudes. Two 20-something British men were arrested today under suspicion of being the mysterious LulzSec and Anonymous mastermind "Kayla."

The newest hacker gang isn't after credit card numbers or classified NATO documents. Their game is blockbuster scripts, verified Twitter accounts and nude cell phone snapshots. Harden your passwords, glitterati: Hollywood Leaks will use any means necessary to bust open the entertainment industry.

Hopefully no one plans to leave downtown San Francisco this evening, because the whole area is set to be consumed in an angry four-way rage fest over the BART subway system, a fest that now includes a counterprotest in support of a BART official whose nude photo was leaked by protesters.

Anonymous has declared war on San Francisco's commuter subway system, BART. They've staged protests and hacked website, but a leak of nude pics of a BART spokesman has taken things to another, more personal level.

One week ago, for the duration of rush hour, officials shut down all four downtown San Francisco BART stations — the heart of the commuter subway system — in response to a small protest by Anonymous. Today, the hacktivists are back. Whether the chaos returns is up to BART.

Anonymous has hacked an exec at Vanguard Defense Industries, a Texas-based defense contractor, and reportedly stolen a gigabyte of data. This follows earlier hacks on federal contractors HBGary, and more recent attacks on San Francisco's BART system.

Anonymous isn't done with San Francisco's BART yet. After a leak of BART passenger data and a real-life protest in retaliation for BART cutting cell service in their stations to squelch protest, Anonymous has leaked what it claims are the email addresses, passwords, and addresses of 102 BART officers.

San Francisco subway system BART thought that cutting off cell phone signals last week would help it avoid trouble with protesters. Instead, it re-inflamed demonstrations and brought in the feds to boot.

It's been a busy weekend for the hacking collective known as Anonymous. Their Operation Fullerton may not have panned out, but Project BARTway was a rousing success. (If you measure success in Thousands of Civilians' Personal Information Being Compromised in the Name of Free Speech.) As they had warned, Anonymous has infiltrated Bay Area Rapid Transit System on Sunday, unfurling their pirate flag logo on the homepage of myBART.com — a promotional website — and, more disconcertingly, releasing the personal information of thousands of myBART.com users.

It's not just the London police and Middle East dictators who try to curb unrest by clamping down on communications networks. According to reports, police in San Francisco are jamming cell phones to head off protesters.

The internet is quaking with the news that the hacktivist collective Anonymous plans to "destroy" Facebook on November 5th. We spoke to the Anonymous member who was there at the start of "Operation Facebook," and he told us the whole thing is a misunderstanding that's spiraled crazily out of control.

Three New York high schoolers have had their computers carted away by the feds for allegedly participating in an Anonymous attack against Koch Industries, the toilet paper company owned by Republican power-siblings Charles and David Koch. The Anonymous crackdown continues.

Hackers have reportedly broken into Norway shooter Anders Behring Breivik's email account and turned the contents over to police in an effort to help their investigation. See, hackers aren't all amoral cybermonsters.

As the Syrian military continues the Ramadan massacre of its own people, the hacktivists of Anonymous took control of the Ministry of Defense's website today, posting images of dead protesters with the following message:

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 Twitter account widely believed to belong to right-wing Norwegian terrorist Anders Behring Breivik was hacked on Sunday by a person or group claiming affiliation with Anonymous Norway.
