TOP OF THE NEWS
Treasury Department Web Sites Redirect Visitors to Malicious Sites (May 3, 2010)Several US Treasury Department web sites are redirecting visitors to other sites that try to install malware on their computers. The attack uses an embedded iframe in three Treasury web sites that invokes scripts from another site. The malware affects only computers that have not previously visited Treasury web sites. Evidence suggests that the attacks are related to the infections several weeks ago of sites hosted by Network Solutions. The affected treasury sites are all hosted by Network Solutions, and the owner of record of the malicious sites used in the attack is the same as the owner of record for the sites used in the previous attacks.
[Editor's Note (Pescatore): Government websites tend to have a higher than average level of security, but it is mainly because there are very few government web sites doing any kind of complex commerce or any actual transactions at all. They are mostly information publishing sites, where vulnerabilities are relatively easy to discover - if you are looking for them.
(Paller): The agency was directly following NIST guidance. Two and a half years after PCI required application security testing, and more than a year after a DHS web site tried to infect visitors' machines, NIST added the relevant control to 800-53. However, without explanation, NIST told agencies they did not have to apply that control for low risk systems. It is low risk systems at DHS and now Treasury that are infecting visitors' computers. This error reflects a fundamental lack of understanding of cyber threat at NIST. Only NSA, DHS, and the NIC-JTF have that knowledge. That the US House Science Committee in Congress continues to demand that NIST write security regulations for areas it doesn't understand demonstrates a level of disregard for national security that is breathtaking. ]
Chinese Government Requires Disclosure of Encryption Keys Prior to Product Purchase (April 29 & 30, 2010)As of May 1, vendors of certain products who wish to continue doing business with government agencies in China are required to disclose specifics of the encryption technologies their products use. The requirements affect 13 technologies, including firewalls, routers, smartcards, database security tools, anti-spam products and intrusion detection products. Before these products can be sold to the Chinese government, they must be tested and certified by the country's Certification and Accreditation Administration (CNCA). There are concerns that the requirement would allow proprietary information to be leaked to Chinese competitors and that other countries may be wary of doing business with companies that disclose this sort of information to the Chinese government.
[Editor's Note (Pescatore): Of course, the US Federal Government and many EU governments have requirements that certain products have to be certified under the National Infrastructure Assurance Program or Common Criteria evaluation regime, and standards like FIPS 140-2 for crypto code, and vendors have to give the testing labs all kinds of sensitive information and actual code to go through the testing. Now, under the Common Criteria evaluation scheme the labs are private firms but they are certified by government agencies. The real difference is that most of the rest of the world agreed to a *Common Criteria* evaluation regime with a lot of transparency. China is going in the exact opposite direction and vendors will face a lot of risk. ]
Appeals Court Upholds Ruling Allowing Disclosure of Suspected Copyright Violators' Identities (April 29, 2010)The 2nd US Circuit Court of Appeals has upheld a ruling that allows the recording industry and other digital entertainment copyright holders to uncover the identities of users believed to be violating copyright law by sharing content through peer-to-peer (P2P) networks. The suit was brought by a student at the State University of New York (SUNY) at Albany seeking to stop a judge's order that his identity be turned over to the Recording Industry Association of America (RIAA) after the organization claimed it detected illegal filesharing activity on an IP address associated with the student.
USAF eMail Security Exercise has Unforeseen Consequences (April 29, 2010)As part of a planned security test examining how they would respond to phishing messages, airmen at Andersen Air Force Base in Guam received email messages telling them that Transformers 3 would be filming at the base. The messages said that the production was seeking airmen to serve as extras on the shoot and provided a link to a site that asked them for personal information. Many of the message recipients supplied the information to the website. Some airmen were excited enough about the prospect of being an extra in the film that they posted the information on the Internet. The news spread and caught the attention of local media, forcing the security testers to send out clarification that the messages had been part of a test.
[Editor's Comment (Northcutt): This is a hard problem. It is pretty clear that security awareness alone is not effective. So you try inoculation, actually phishing, but in a controlled way. However, this is not the only time this has gone awry. In one company, they just ignored subsequent emails from the security department. Very clever phish though, I am sure people were excited about the opportunity to work around Megan Fox/ Mikaela Banes. Turns out the bloggers were picking up the post from "Supershaggy" to ComicBookMovies.com pretty fast.

THE REST OF THE WEEK'S NEWS
Opera Updates Browser to Fix Severe Vulnerability (April 30 & May 3, 2010)Opera has released an update to address an "extremely severe" vulnerability in the Mac and Windows versions of its browser. The flaw lies in a script that handles document files and could be exploited to inject and run code on vulnerable computers. Users need only visit specially crafted web pages for the exploit to be effective. Users are urged to update to Opera version 10.53.
Summit Aims to Foster International Discussion on Cyber Threats (May 2 & 3, 2010)This week welcomes more than 400 government officials and executives from countries around the world who will meet in Dallas for the Worldwide Cybersecurity Summit. One of the goals of the meeting is to encourage officials to talk to each other about how to fight common cyber threats and develop ways to work together across geo-political borders. The event is organized by the EastWest Institute think tank.
Kernell Guilty on Two of Four Charges in Palin eMail Intrusion Case (April 30, 2010)Former University of Tennessee student David Kernell has been found guilty on two of four counts in a case regarding his having broken into Sarah Palin's Yahoo mail account. The jury deliberated for four days before finding Kernell guilty of obstruction of justice and misdemeanor computer intrusion. Kernell was acquitted of a fraud charge and the jury was deadlocked on a charge of identity theft, for which he could be retried. Using publicly available information, Kernell broke into Palin's Yahoo mail account during the former Alaska governor's vice-presidential candidacy. Kernell was convicted of the obstruction of justice felony charge because he deleted evidence from his hard drive. Kernell could face up to 20 years in prison.
Wiretaps Up 26 Percent in 2009 (April 30, 2010)Between 2008 and 2009, the number of wiretaps authorized by US state and federal judges rose 26 percent. No wiretap requests were refused. In 2009, there were 2,379 criminal wiretaps authorized, the vast majority of which were for mobile phones in drug cases. Each authorized wiretap captured communications of an average of 133 individuals; just 19 percent of the communications captured were incriminating. Each tap lasted an average of 42 days. In 2009, information gathered from the wiretaps led to 4,537 arrests and 678 convictions. Investigators came across just one instance of encrypted communications in the 2009 wiretaps, and were able to obtain plaintext versions of those messages. The statistics do not include terrorism-related wiretaps or wiretaps conducted through the National Security Agency's warrantless wiretapping program.
US Has Highest Data Breach Costs (April 30, 2010)According to a study released by the Ponemon Institute, the cost associated with data breaches is higher in the US than in any other country. Overall, breach costs were higher in countries that have notification laws. The breach cost incurred by organizations in the US is 43 percent higher than the worldwide average. The average cost of a data breach per record is US $142 worldwide; the average cost of a data breach per record in the US is US $204. Last year, Germany passed a law that requires breach notification; costs associated with breaches there are the second highest in the world at US $177 per record. The cost per record in the UK is US $98; only public sector organizations and financial institutions are required to disclose data breaches. The highest overall cost associated with breaches was lost business. The study was sponsored by PGP.
[Editor's Note (Lee): The incredibly high cost of data breach incidents have backfired and resulted in many companies choosing to remain silent even though breach laws exist. In addition, victims are less willing to involve law enforcement if they intend to keep the event closely held. Even in business schools, the question of notification has been raised as a case study for future executives.
(Schultz): Why do the conclusions of this "research institute's" research so often coincide with the wishes of the sponsors' marketing organizations? ]
Contractor Gets Five Years for Automated Clearing House Credit Union Thefts (April 29 & 30, 2010)Zeldon Thomas Morris has been sentenced to more than five years in prison for stealing US $2 million from banks while working as an IT administrator. Morris was a third-party contractor hired to help several credit unions upgrade their systems; because of his position, he was granted unrestricted local and remote access to their networks. Morris abused his position to conduct several Automated Clearing House (ACH) transactions, depositing the withdrawn funds into accounts he owned. By using phony or already used ACH "racing numbers," his activity went undetected. Morris was caught after his business partner alerted one of the credit unions of unusually large deposits being made to a joint business account. In addition to prison time, Morris was ordered to pay more than US $1.8 million in restitution and forfeit personal property.
[Editor's Note (Northcutt): Short sentence; he was facing 30 years.
Microsoft Suggests Workaround for SharePoint XSS Vulnerability (April 30, 2010)Microsoft has issued a warning about a zero-day cross-site scripting (XSS) vulnerability in SharePoint products. For the attack to work, users must be manipulated into clicking on a maliciously crafted link. The flaw can be exploited to steal information from vulnerable servers. Microsoft is suggesting that until a fix is ready, users apply an interim workaround that involves disabling the SharePoint help system. Microsoft is also recommending that users run Internet Explorer 8 (IE 8), because it contains a XSS filter. Administrators will need to change the browser's settings to turn on the filter for the Local Intranet security zone.
