WASHINGTON -- A group of hackers who breached the Senate computer system earlier this week claimed responsibility for problems with the CIA's website Wednesday.
The group, known as Lulz Security, tweeted "Tango down - CIA.gov," and there were problems throughout the early evening accessing the agency's website.
The attack appeared to be targeting the CIA"s public website, which does not include classified data and has no impact on the CIA's operation. CIA spokeswoman Marie Harf says the agency is looking into the reports.
It is sometimes difficult to tell if a website has been hacked, or if the claim alone drove so many people to the site that it crashed.
Lulz has claimed credit for other high-profile hacks, often suggesting the group is trying to highlight cyber security weaknesses.
