Volume XII - Issue #82

October 15, 2010

Stuxnet was a wake up call for every organization managing critical systems - but now what? On Thursday, Oct 21, at 3 PM ETD, SANS instructor John Strand will provide insight into how this worm first compromises a system and how it spreads. More importantly, he will also cover methods to help detect these attacks in your environment in the future. This webcast is one of the regular updates in the Human Sensor Network training program SANS developed first at Sandia National Labs, to train system administrators as the first line of hacker detection. If you are part of an organization that can benefit from this new program, and would like to see this sample of the continuing education program, contact Scott Weil, sweil@sans.org, for registration instructions.

DHS and NSA Announce Cyber Defense Partnership (October 13 & 14, 2010)

The US Department of Homeland Security (DHS) and the National Security Agency (NSA) announced that they will work together to help protect the country's computer systems from cyber attacks. Each agency is creating a small team to work within the other's operation center. Civil liberties watchdog groups have expressed concern about the collaboration; they say that there is the possibility that citizens' privacy rights could be violated. The plan calls for oversight by legal and privacy experts. The arrangement hopes to avoid the need to duplicate the other agency's cyber security efforts.

Facebook Launches One-Time Password Service (October 13 & 14, 2010)

Facebook has begun a one-time password service to allow users to log in to their accounts on public computers without having to use their established passwords. The system works by users registering a certain mobile phone number with Facebook. When they text "OTP" to a number provided by Facebook (32665), they will receive back a one-time password that is good for 20 minutes. The idea is to prevent users' regular passwords from being captured by keystroke logging software on public computers. Facebook has also launched a feature that allows users to log out of their accounts remotely and a service that prompts users to update their security information.

[Editor's Note (Pescatore): The beauty of the cellphone as an authentication token is that is the only token that is *not* "yet another thing to carry." Not that SMS as done today is terribly secure, but by avoiding YATTC *and* raising the bar against password stealing attack, this approach (supported by Google previously, as well) is a nice step forward. ]

Adobe Reader 10 Will Include Sandboxing (October 12 & 13, 2010)

Adobe plans to release a more secure version of Reader by the end of the year. Adobe Reader has become an increasingly popular target for exploit writers. Adobe Reader 10 will include a sandbox feature designed to prevent attacks that will harm computers. The feature will be turned on by default. Adobe director for product security and privacy Brad Arkin harbors no illusions that the new version of Reader will be immune from security issues, acknowledging that "bad guys and researchers won't give up because this is an exciting challenge."


Smart Grid Standards (October 14, 2010)

The National Institute of Standards and Technology (NIST) has released five sets of smart grid interoperability and cyber security standards for consideration and adoption by state and federal regulators.


In Europe, ATM Skimming is Up, but Losses are Down (October 14, 2010)

According to statistics gathered by the European ATM Security Team (EAST), the number of reported skimming attacks on European ATMs increased during the first half of 2010, but the total monetary losses fell. There were 5,743 reported attacks in the first six months of 2010, a three percent increase over the second half of 2009 and a 24 percent increase over the first half of 2009. Total losses during the first half of 2010 were 143.5 million Euros (US $201.6 million), down seven percent from the second half of 2009, when losses were 154.1 million Euros (US $216.5 million). The decline in losses is believed to be due in part to the growing use of chip and PIN technology.


[Editor's Note (Pescatore): The fact that skimming works so well against swipe cards points out that adding "what you have" authentication only works well when the "what you have" isn't easily duplicated. That's the benefit of chip and pin, and the benefit of SIM chips in cellphones, too. ]

Microsoft Blames Human Error for Spammers Gaining Control of Network Devices (October 13 & 14, 2010)

Microsoft says human error is to blame for spammers gaining control of two computers on the company's network. An internal investigation found that "two misconfigured network hardware devices in a testing lab were compromised." Those devices have been removed. The servers had been manipulated to route traffic to more than 1,000 fraudulent websites. The devices were running a Linux kernel. One of the compromised IP addresses was used to launch a distributed denial-of-service (DDoS) attack against KrebsOnSecurity.com in late September.


[Editor's Note (Schultz): Microsoft security has improved *so* much over the years, yet at the same time, this company too often continues to conveniently blame forces it claims are out of its control when security within goes awry, as in this news item. I find Microsoft's singling out Linux security as one of the causes of incidents discussed in this news item to be particularly amusing. ]

RIM Issues BlackBerry Enterprise Server Update (October 13, 2010)

An interim security update for Blackberry Enterprise Server (BES) 5.0 Service Pack 2 for Microsoft Exchange and IBM Lotus Domino addresses a vulnerability that could be exploited to gain access to BES infrastructures, create denial-of-service conditions or possibly execute arbitrary code. The flaw affects BES Express as well. For an attack to be successful, users would need to be manipulated into opening a maliciously crafted PDF file on a BlackBerry smartphone associated with a user account on a BES. Research in Motion (RIM) urges administrators to update their software as soon as possible, but cautions that the update must be done carefully, because if it is done incorrectly, it could cause additional problems.


US Has the Most Bot-Infected PCs (October 13 & 14, 2010)

According to Microsoft's Security Intelligence Report, the US has 2.2 million PCs infected with bot software, more than any other country in the world. Brazil ranks second with 550,000. The highest rate of infection was found in Korea, where 14.6 of every 1,000 PCs, or 1.5 percent of PCs, are infected with bot software. The types of botnet malware detected most often were Rimecud, Alureon and Hamweq. A botnet named Lethis was reportedly responsible for 56 percent of botnet spam between March and June 2010. The statistics were gathered through 600 million PCs that use Microsoft's update services and/or its Essentials and Defender security products.


Microsoft Patches Include Fix for Flaw Exploited by Stuxnet (October 12, 2010)

On Tuesday, October 12, Microsoft issued 16 security bulletins to address 40 vulnerabilities in Windows, Internet Explorer and Office. Microsoft considers patches described in two of the bulletins - MS10-071 and MS10-076 - to be the most critical to apply as soon as possible. Both address vulnerabilities that could be exploited through drive-by attacks. One of the vulnerabilities addressed in Tuesday's release (MS10-073) is exploited by Stuxnet. Two of the four zero-days in Windows that Stuxnet has been exploiting have already been fixed; the fourth will be addressed in a future update. Microsoft has also updated its Malicious Software Removal Tool to detect the ZeuS Trojan horse program.




Pennsylvania School District Settles Webcam Lawsuits for US $610,000 (October 12, 2010)

The Pennsylvania school district accused of using embedded webcams to spy on students at home has agreed to pay a US $610,000 settlement to bring an end to litigation brought by two students. Roughly 70 percent, or US $425,000, of the settlement amount will go to attorneys' fees; the remaining US $185,000 will go to the students. The tracking software at issue in the case was placed on 2,300 school-owned laptop computers that were issued to Lower Merion County high school students. The software was supposed to be used to locate missing or stolen computers, but the school allegedly allowed the feature to remain on after missing computers were located, resulting in pictures being taken of students in their homes.

[Editor's Note (Northcutt): $425K to the lawyers, $185k to the students. Does this seem wrong? In Rising Above the Gathering Storm, the author writes that US companies spend more money on litigation than they do on R&D.
