A group going by the name of the “Tunisian Cyber Army”, claims that they, in coordination with the Al-Qaida Electronic Army (AQEA), have hacked four U.S. government sites within the last few days. ┬áThe sites allegedly hit included the U.S. State Department, the Army National Guard, the U.S. Customs and Border Protection (cbp.gov) and Office of Personnel Management (OPM.gov).

The hackers says they identified and exploited vulnerabilities on two domains owned by the US Department of State and one for the Army National Guard.  The attackers claim to have obtained sensitive information, including the IP addresses of government computers and servers. The groups says it is holding onto the information to work on hacking more IPs.

The group also says they had the assistance of “Chinese hackers”.

The group claims that this is all in prepation for #OpBlackSummer, an effort to attack US targets between May 31 and September 11.

They have contacted a few hacking media websites to present the evidence of their attacks, showing the links to the vulnerabilities that they claim to have exploited. Those sites, E Hacking News, Hack Red and Ill Secure believe the claims to be valid. Softpedia also believes that the hacks are legitimate.

The group has not as yet provided pastebin evidence of data seized or other usual proof of successful attack, however. They claim to be holding 72GB of data that they say they will drop on May 31 at the start of #OpBlackSummer. They say they want to use some of that information to make further attacks.

The group has claimed responsibility for prior hacking attacks against CBN (Christian Broadcasting Network) as well as against banks. They previously posted a pastebin of what appears to be data from a prior attack on a bank.

The government has not as yet confirmed these alleged attacks on government sites. However, if the government sites actually have the vulnerabilities cited, that would be troubling as they are things one would not think should be an issue in Dept of State or Defense websites.

The group says their next targets will be gas, petrochemical and possibly nuclear companies, and that they will be scheduling a “conference” soon to explain #OpBlackSummer.

At the end of #OpBlackSummer, they make the following threat:

We will keep you apprised of developments in this case.
