The names, email addresses, birthdays and encrypted passwords of some 1.3 million Sega customers were hacked, the company revealed today. The hack targeted SegaPass, "a newsletter and online game service operated by [Sega's] European subsidiary," but luckily, since the company uses a third-party vendor to handle payment, no credit card or bank information was accessed.

Bitcoin, the virtual currency that has sparked a digital gold rush, is now being targeted by malicious nerds seeking a quick payday. A new Trojan automatically scans for Bitcoins and steals them.

In honor of its thousandth tweet—and on the heels of compromising the websites of the CIA, US Senate, Sony, and more—the crew of the good ship LulzSec has presented the world with a manifesto of sorts. [Gizmodo]

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!

Last week, Citigroup admitted it had been hit by hackers in May who used a super-simple browser trick to make off with account information on more than 200,000 of the bank's credit card customers.

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

If you lock your iPhone behind a passcode, there's a good chance you've chosen from one of just 10 extremely common combinations. It's time to switch to something that actually protects your data.

You know what should be one of the hardest things in the world to do? Break into a bank and make off with tens of thousands of bank accounts. But hackers waltzed into Citigroup's website and did just that without breaking a sweat.

Hacker collective LulzSec cracked into Senate.gov today, shortly after a loosely affiliated group, Anonymous, took down the website of the Spanish national police force. This is starting to look like the most embarrassing world war on record.

As if it didn't have enough to deal with already, the International Monetary Fund admitted to staff on Wednesday that it was the victim of a "large and sophisticated cyberattack," one that occurred over the last few months and led to a "very major breach."

In this corner, the amorphous blob of Wikileaks-loving nerds: Anonymous! And in this corner, the sometimes-relevant intergovernmental military alliance NATO! NATO wants to kill Anonymous, but Anonymous says back off.

Citigroup discovered in early May that hackers accessed data on about 200,000 of its customers, including names, emails and account numbers, according to Reuters. Luckily Citi promptly notified customers one month later.

Fully a quarter of illicit hackers may have been turned into federal informants, the publisher of a prominent cybercrime journal estimates. It turns out that pasty skinny computer nerds don't hold up well to police pressure. Go figure.

The FBI-affiliated "public-private partnership" Infragard Atlanta was hacked on Friday evening, exposing what's purported to be the non-profit company's user database and defacing the website ("LET IT FLOW YOU STUPID FBI BATTLESHIPS.") The perpetrators? Our old friends at Lulz Security.

Sony getting its ass handed to it by hackers is becoming about as newsworthy as a netbook release, but this one is particularly brutal: Lulz Security just released a file containing over a million user logins. Home addresses included. [Gizmodo]

Weinergate is the biggest mystery to hit the internet since Sarah Palin's pregnancy. Is it really him? Was it a hacker? a Jealous lover? Thousands of cyberdetectives are on the case! And they (almost) all suck.

The hacking group Lulz Security had a hit with their Tupac-themed hacking of PBS last weekend. Now they claim to have hacked Sony. And they want everyone to know!

Will the plague of "hacked" political Twitter feeds never end? As Anthony Weiner struggles to stand firm in the aftermath of his dick twitpic scandal, the Republican speaker of the Ohio House has announced that his Twitter was hacked, too. The result: A couple liberal tweets about Ohio policy stuff, which Speaker William Batchelder did not approve. Bo-ring. Go glans or go home.

Thanks to its recent attacks on the Chamber of Commerce and security firm HBGary, anarchic hacker collective Anonymous has popped up on the radar of NATO, which worries that the cheeto-fingered dorks "could potentially hack into sensitive government, military, and corporate files." (Just kidding about the cheetos, guys! Don't hack us!)

Some Chinese hackers may have been reading top U.S. officials' email for a while. Google says they've thwarted a phishing campaign that targeted the Gmail accounts of politically sensitive targets.
