LulzSec, the hacking and prankster collective that has attacked the US Senate, Sony, and the Fox and PBS television networks, has struck again, claiming it was behind an assault that took down the website for the Central Intelligence Agency.
Attempts to access cia.gov on Wednesday afternoon were met with only limited success. LulzSec claimed responsibility for the brief and only partial outage, writing in a Twitter post: "Tango down - cia.gov - for the lulz."
The website contains no classified material, but bringing down the public portal of one of the world's most powerful government agencies would nonetheless be LulzSec's most brazen prank to date. There was no way to independently verify the group's claim of responsibility.
A CIA spokeswoman told the Associated Press that officials are investigating the reports. Such outages are often the result of DDoS, or distributed denial of service, attacks. The assaults generally require little skill to carry out.

Avoid tech support phone scams
Cybercriminals don't just send fraudulent email messages and set up fake websites. They might also call you on the telephone and claim to be from Microsoft. They might offer to help solve your computer problems or sell you a software license. Once they have access to your computer, they can do the following:
• Trick you into installing malicious software that could capture sensitive data, such as online banking user names and passwords. They might also then charge you to remove this software.
• Take control of your computer remotely and adjust settings to leave your computer vulnerable.
• Request credit card information so they can bill you for phony services.
• Direct you to fraudulent websites and ask you to enter credit card and other personal or financial information there.
Neither Microsoft nor our partners make unsolicited phone calls (also known as cold calls) to charge you for computer security or software fixes.
Telephone tech support scams: What you need to know
Cybercriminals often use publicly available phone directories so they might know your name and other personal information when they call you. They might even guess what operating system you're using.
Once they've gained your trust, they might ask for your user name and password or ask you to go to a website to install software that will let them access your computer to fix it. Once you do this, your computer and your personal information is vulnerable.
Do not trust unsolicited calls. Do not provide any personal information.
Here are some of the organizations that cybercriminals claim to be from:
