The Secret Internet Protocol Router Network (SIPRNet) is "a system of interconnected computer networks used by the United States Department of Defense and the U.S. Department of State to transmit classified information (up to and including information classified SECRET) by packet switching over the TCP/IP protocols in a 'completely secure' environment".
It also provides services such as hypertext document access and electronic mail. As such, SIPRNet is the DoD’s classified version of the civilian Internet.
SIPRNet was allegedly one of the networks accessed by alleged whistleblower Bradley Manning, who allegedly leaked the video used in Wikileaks' Collateral murder as well as the source of the US diplomatic cables leaked by WikiLeaks in November 2010
DDOS attack on WikiLeaks
The first thing that struck Wikileaks.com was a powerful DDoS attack, targeting the company's Domain Name Service (DNS) servers. Under the control of an unknown cyber criminal, a network of thousands of enslaved computers simultaneously sent huge amounts of requests to the Web site's DNS servers. The bogus traffic from the DDoS attack reached peaks of 500Mbps and quickly flooded the DNS servers, bringing the whole Web site down.
Could this be the first attack bij an government against a website ? Or is this like the same scheme regarding The Pirate Bay ?
