DHS chief: Cybersecurity efforts are 'classified'
September 5, 2007
Security researchers said the memorandum, which was obtained by The New York Times from an executive at a private company, included a list of Web and Internet addresses that were linked to locations in China. However, they noted that such links did not prove that the Chinese government or Chinese citizens were involved in the attacks. In the past, intruders have compromised computers in China and then used them to disguise their true location.
Officials at the lab, Oak Ridge National Laboratory in Tennessee, said the attacks did not compromise classified information, though they acknowledged that they were still working to understand the full extent of the intrusion.
The Department of Homeland Security distributed the confidential warning to computer security officials on Wednesday after what it described as a set of "sophisticated attempts" to compromise computers used by the private sector and the government.
Government computer security officials said the warning, which was issued by the United States Computer Emergency Response Team, known as US-CERT, was related to an October attack that was also disclosed last week by officials at the Oak Ridge laboratory.
According to a letter to employees written by the laboratory's director, Thom Mason, an unknown group of attackers sent targeted e-mail messages to roughly 1,100 employees as part of the ruse.
"At this point, we have determined that the thieves made approximately 1,100 attempts to steal data with a very sophisticated strategy that involved sending staff a total of seven 'phishing' e-mails, all of which at first glance appeared legitimate," he wrote in an e-mail message sent to employees on Monday. "At present we believe that about 11 staff opened the attachments, which enabled the hackers to infiltrate the system and remove data."
In a statement posted on the laboratory's Web site, the agency stated: "The original e-mail and first potential corruption occurred on October 29, 2007. We have reason to believe that data was stolen from a database used for visitors to the Laboratory."
The laboratory said the attackers were able to gain access to a database containing personal information about visitors to the laboratory going back to 1990.
The US-CERT advisory, which was not made public, stated: "The level of sophistication and the scope of these cyber security incidents indicate that they are coordinated and targeted at private sector systems."
The US-CERT memo referred to the use of e-mail messages that fool employees into clicking on documents that then permit attackers to plant programs in their computers. These programs are then able to copy and forward specific data--like passwords--to remote locations.
Despite improvements in computer security, phishing attacks are still a big problem. In the case of the Oak Ridge intrusion, the e-mail messages were made to seem authentic. One described a scientific conference and another referred to a Federal Trade Commission complaint.
Computer security researchers cautioned that despite the US-CERT description of the attacks as sophisticated, such threats are frequently undertaken by amateur computer hackers.
Classified federal computer networks are not supposed to be connected physically to the open Internet. Even so, sensitive data like employee e-mail databases can easily be compromised once access is gained to computers inside federal agencies.

No cyber crook worth his salt will allow themselves to be tracked back to home base that easily, not when it is so simple to hop from machine to machine to cover your tracks.
Nope, I can't see it.

"We take exception to the continual smears from the West about our space capability and about our alleged culpability in cyber-attacks."
Continuing on, with an obvious slur on the American Revolution, he added, "Very soon, we will demonstrate space superiority by orbiting a large number of cattle. This will be the "herd shot 'round the world!
Finally, he concluded, "Then we will suck all the data out of the DHS servers to show how professional cyber-attacks are done."
