2008 Malware Infection Prompted Cyber Security Revamping at U.S. DoD (December 8, 2011)

The Washington Post's Ellen Nakashima has written a detailed account of the worm that infected US military computers in 2008. Cyber security specialists first became aware that something was not as it should be in October 2008, when they noticed something on the classified military system acting as a beacon, trying to "phone home." The affected network contained highly sensitive information, including battle plans for commanders in Iraq and Afghanistan. Analysis determined that the malware made its way into the system through a thumb drive. The incident has been a driving force behind the government's revamped approach to cyber security. The effort to contain the malware and prevent any further damage was known as operation Buckshot Yankee. Nakashima's article includes information that has not before been disclosed, gleaned from interviews with people who have knowledge of the operation. The malware, known as Agent.btz, was discovered on the military computer system of a NATO-member government in June 2008. In October 2008, it showed up on the US's Secret Internet Protocol Router Network, or SIPRNet, which is used by the Departments of State and Defense to transfer classified information. Once the system was infected, any thumb drives that were subsequently attached to it became infected as well. The fix was laborious and time consuming - infected computers needed to be identified, taken offline, scrubbed, and reformatted. The infection also led to the ban of thumb drives on Defense Department computers in November 2008. The ban has been partially lifted because other security measures are now in place. The incident was a major driver behind the creation of Cyber Command. It served as a reminder that humans are the weakest link and raised questions about parameters and rules for cyber warfare.

Google Removes Malicious Apps from Android Market (December 12, 2011)

Google has pulled more than 20 malicious applications from the Android Market, bringing the total number of apps removed this year to over 100. The malware that was bundled with the removed apps has been dubbed "RuFraud." It sends text messages to premium rate phone numbers, incurring charges for users and accruing profits for those who reap the revenue of the numbers. The malware was written not to affect users in the US, but users in several European countries and in Asia are affected.

[Editor's Note (Pescatore): The "Droid Does" marketing campaign was trying to portray Google's wide open Market as an advantage over Apple's more restrictive App Store. However, the consumer marketplace is definitely demanding more security testing *before* apps are released and *less* need to remove malicious apps *after* they've done damage. "Droid Does Have Malware" is not a great sales pitch...
(Murray): The fundamentally open strategy of Android is dangerous. Early prevention trumps late remediation. ]

Georgia Medical Center Turns Away Patients Because of Malware Infection (December 9 & 10, 2011)

Last week, a hospital in Georgia had to ask ambulances to take patients to other area hospitals after its computer system became infected with malware that slowed down patient registration and other functions. The cyber infection was discovered on Wednesday, December 7; the hospital reverted to old-fashioned paperwork. The malware affected patient registration times, pharmacy operations, and accessibility to radiology and laboratory results. Gwinnett Medical Center, which is a trauma center, accepted severe cases such as respiratory distress, cardiac issues, and other traumas, but sent other cases to area hospitals. The center was back to accepting all patients as of Saturday evening, December 10.


[Editor's Comment (Northcutt): Hmmm, the malware is believed to be Silly FDC, spreads largely by USB removable media and several sites say it is fairly harmless:

SOPA Amendments Aim to Clarify Proposed Anti-Piracy Legislation (December 12, 2011)

US Representative Lamar Smith (R-Texas) has introduced changes to the controversial Stop Online Piracy Act (SOPA) that appear to temper the proposed legislation's reach. Originally, SOPA allowed rights holders to have payment processors cease doing business with suspect sites websites without a judge's approval. Now, before a site can be taken down, the rights holders must obtain an order from a judge to get payment processors to sever business dealings with the suspect sites. The legislation will not apply to sites that end with .com, .net, and .org; only foreign websites will be subject to SOPA's provisions. Remaining untouched are provisions that allow the DoJ to demand that Internet service providers (ISPs) block customers from visiting these sites. The bill no longer requires ISPs to alter DNS, but they may still choose to do so to comply with blocking orders.


Most US Data Theft Originating in China is the Work of a Dozen Groups (December 12, 2011)

The bulk of data theft committed against the US companies and government agencies appears to be conducted by about 12 Chinese groups, according to analysts. Most of the groups are backed by the Chinese government. The analysts, who have worked with businesses and the government regarding cyber intrusions, say that the attacks bear signatures that identify them as being part of certain hacking groups.


[Editor's Note (Murray): These anonymous sources carry about as much weight as water cooler gossip. ]

Six Arrested in Connection with Student Loan Phishing Scheme (December 9, 10 & 12, 2011)

Six people have been arrested for their alleged roles in a phishing scheme that targeted university students in the UK. The phishing emails included a link that, when clicked, took the recipients to a site where they were asked to update their personal information for their student loan accounts. Those allegedly involved with the scheme used the stolen information to access students' bank accounts and steal funds. In all, police say the cyber thieves stole more than GBP 1 million (US $1.56 million).


Telstra Customer Database Accidentally Exposed (December 9, 10 & 12, 2011)

Telstra has reset passwords for 60,000 accounts after a data breach exposed the information. The telecommunications and media company took its customer self-service site offline after learning that the information had been inadvertently exposed when Google indexed it. The compromised data include passwords, usernames, and addresses. An internal investigation has been launched to determine how the data came to be exposed and to prevent the situation from recurring, and Australia's Privacy Commissioner is also investigating the breach.




Senator Wyden Seeks Answers About Domain Seizure Operation (December 9 & 11, 2011)

US Senator Ron Wyden (D-Oregon) wants answers from the Department of Homeland Security (DHA) about a program known as In Our Sites, an operation in which domains were seized, after learning that a music review site had its name kept for a year without giving the domain's owner an opportunity to challenge the seizure. The site in question,, was seized in November 2010 for allegedly letting users download music that had not yet been released. In this case, some of the music had been sent to the site by the artists or their labels. All documents relating to the seizure were sealed expect for the initial court order filing. The site was returned late last week by the Immigration and Customs Enforcement, which is a part of DHS, with the acknowledgment that the seizure was unwarranted.

Two Flaws in Adobe Flash Player (December 9, 2011)

The US Computer Emergency Readiness Team (US-CERT) has issued an advisory warning of a pair of vulnerabilities in Adobe Flash Player. The remote code execution flaws are exploitable through malicious Flash content placed on websites or in PDF documents. The company that disclosed the flaws does not plan to contact Adobe about them, having announced several years ago that it would no longer notify vendors of flaws it finds in their products. No attacks have been detected in the wild. Internet Storm Center:

Microsoft Issues Offline Windows Defender Beta (December 9 & 12, 2011)

Microsoft has issued a beta offline version of its Windows Defender anti-malware tool. The tool will be especially useful for users whose machines are infected with malware that prevents them from accessing security sites because it can be used to boot infected PCs.


Judge Rules That Some Banks Failed to State Proper Claims for Seeking Damages from Heartland (December 7 & 9, 2011)

US District Judge Lee Rosenthal has dismissed all but one of the claims brought by banks against Heartland Payment Systems regarding the data breach that exposed payment card account information. Heartland disclosed the breach in 2009; it actually took place in 2007. The civil complaints filed against Heartland were consolidated in the Southern District of Texas and were separated into consumer complaints and financial institution complaints. Judge Rosenthal said that the majority of the banks had not provided proper claims to seek damages; his ruling allows them to amend their claims.
