New Commission To Look For Overhaul of US Cyber Security Policy (October 30, 2007)

The US House Homeland Security Committee launched a new cybersecurity commission that will provide recommendations on how to improve the state security of public- and private-sector computers and networks, to the next president. In a rare show of bi-partisanship, both the Ranking Minority Member and the Chairman (McCaul or Texas and Langevin of Rhode Island) of the SubCommittee on Emerging Threats and Cyber Security agreed to personally chair the new commission. The members of the Commission are a who's who of cyber security expertise. Joining the Congressmen in managing the effort are Bobby Inman who served as Director of NSA and Deputy Director of the CIA and Scott Charney who served as chief of the US Department of Justice's Computer Crime and Intellectual Property Section and now leads Microsoft's efforts to improve the security of its products and to help law enforcement catch criminals. The Commission will be managed by the Center for Strategic and International Studies.

Payment Card Data System Needs Security Overhaul (October 29, 2007)

Gartner analyst Avivah Litan says that to focus solely on retailers' card data security is to take a narrow view of the situation; instead, efforts should be directed toward revamping the payment system's security as a whole. According to Litan, "the banks and the credit card companies could solve this
[data security issue ]
more easily" than the retailers could. Presently, merchants have to retain cardholder data to protect themselves against charge backs and to manage recurring charges and refunds. Banks already have stronger data security measures in place so perhaps they could store the data. Another option would be to require personal identification numbers (PINs) for each transaction; fraud from signature debit transactions is considerably higher than fraud from PIN debit transactions.
-http://computerworld.com/blogs/node/6446
[Editor's Note (Ullrich): The focus on retailers seems to be wrong. While they have a part in the systems security, they didn't design it. At the very least, the payment card industry should at least assist retailers. PINs seem like a sensible improvement.
(Honan): While experience in the UK reinforces Ms. Litan's argument for the introduction of PIN authorised transactions in reducing certain types of fraud, it also demonstrates that criminals will adapt to changing situations. Since the introduction of Chip and Pin in the UK, card-not-present fraud is increasingly at an annual rate of 16% - see

NIST Issues Information Systems Risk Management Draft Document (October 26, 2007)

The National Institute of Standards and Technology (NIST) has issued SP-800-39, "Managing Risk from Information Systems: An Organizational Perspective." The draft report is intended to help US government agencies "apply the NIST Risk Management Framework to government IT systems" and is considered to be "the flagship document in the series of FISMA-related security standards and guidelines developed by NIST." NIST is accepting comments on the draft document until December 14, 2007.

[Editor's Comment (Northcutt): I am glad I am no longer a government worker. This is very high level, with no way to implement anything it does or does not say and tons of external references when it would have been much more effective to have incorporated the relevant sections of those documents inline so that someone can actually use the document. If your life is going to be impacted by this, it might help to download this and send NIST in your comments. ]

LEGAL MATTERS

Bot-Net Operator Draws One-Year Prison Sentence (October 26 & 29, 2007)

Jason Michael Downey was sentenced to 12 months in prison for launching bot-net attacks that caused thousands of dollars in damages. Downey amassed a bot-net of approximately 6,000 computers that he used to launch distributed denial-of-service (DDoS) attacks on a variety of computer systems. He will also serve three years of suspended release, pay US $21,110 in restitution and perform 150 hours of community service.

[Editor's Note (Ullrich): At least when the operators are in the US, these arrests and convictions are becoming more routine. Prosecuting foreign actors is still hard and time consuming, if possible at all. ]

POLICY & LEGISLATION

House Committee Approves Global Online Freedom Act (October 23, 24 & 25, 2007)

The US House Foreign Affairs Committee has approved the Global Online Freedom Act of 2007, which would impose criminal penalties on US Internet companies that provide customers' personal information "to governments that use the information to suppress political dissent." Companies found to be in violation could also face civil penalties of up to US $2 million. In addition, the bill would prohibit ISPs from blocking US government financed content. In two weeks, a House Foreign Affairs Committee panel will question Yahoo! about its role in the case of Chinese journalist Shi Tao, who was jailed after Yahoo! allegedly provided China's government with information that helped identify and locate him.

SPYWARE, SPAM & PHISHING

Grocery Store Chain Nearly Loses Millions to Phishers (October 29, 2007)

The Minnesota-based Supervalu grocery chain nearly lost millions to a pair of phishing attacks. Earlier this year, emails purporting to be from employees at two separate Supervalu suppliers requested that Supervalu send payments to new bank accounts. Over the course of the following week, Supervalu made transfers of more than US $10.3 million into the two accounts; several days later, the company realized it had been duped and contacted the FBI. Most of the money has been recovered.
-http://www.computerworld.com/action/article.do?command=viewArticleBasic&arti
cleId=306300&source=rss_topic17

[Editor's Note (Cole): The problem with phishing attacks is that they look like legitimate email. While user awareness is critical for employees to understand the threat, it must be coupled with technical measures. Many of these attacks use spoofed email addresses, so, an email gateway can be configured to block some of the phishing emails. Email sandboxing and content filtering can also help with this problem. ]

WORMS, ACTIVE EXPLOITS, VULNERABILITIES & PATCHES

Six More Flaws in RealPlayer (October 29, 2007)

RealNetworks has acknowledged an additional half-dozen vulnerabilities in its RealPlayer media player. Just last week, RealNetworks issued RealPlayer updates to address a flaw that was being actively exploited to spread malware. The patched versions are not vulnerable to the newly disclosed bugs, but these new bugs provide even more incentive for users to update their versions. The six flaws involve issues with the way RealPlayer parses certain file formats. The flaws could be exploited to execute arbitrary code. Four of the six flaws affect Mac OS X and Linux systems as well as Windows systems.

issueid=123

-http://searchsecurity.techtarget.com.au/news/article.asp?DocID=1279260
[Editor's Note (Skoudis): I get a little uneasy when a vendor's prior patch retroactively fixes new flaws not yet disclosed. That is, when a new flaw comes to light (or, say six new flaws), the vendor says, "Oh yea... the version we released last week deals with those too!". So, when RealNetworks released their fix last week, their users didn't have an accurate accounting of the risk we faced by not patching or delaying the patch. The vendor may have figured that if they disclosed the other vulnerabilities, it would have given the bad guys a heads up about how to exploit new flaws. There is no good answer here, but I still feel uneasy.
(Cole): With zero day attacks on the rise, patching is not enough. Organizations need to uninstall programs and parts of programs that are not needed. With RealPlayer, for example, some of the components that are exploited are not used by the average person running the software. ]

Trojan Dupes Users Into Deciphering CAPTCHA Images (October 29, 2007)

A Trojan horse program exploits the CAPTCHA protection Yahoo! requires to create accounts. Users are encouraged to play a game wherein a model performs a striptease; each "move" requires the user to decode a different CAPTCHA image. It is unclear how the malware that allows the pop-ups gets onto users' computers, but it is likely to have come as an email attachment.
-http://www.heise-security.co.uk/news/98124
[Editor's Note (Skoudis): I've been waiting for this to happen. Harnessing the human power behind all of those bot-infected machines was inevitable, and leverages the bot-net in a very useful way for attackers. I wonder what other things the bad guys have up their sleeves to social engineer massive numbers of users into doing.
(Shpantzer): Offloading the CAPTCHA decoding process makes sense since the artificial intelligence programs that decode some CAPTCHAs are not as accurate or fast as humans. In 2002, NewsBites noted that the hackers sending decoding work to humans is good and proper evidence that CAPTCHAS are doing their job, since this roadblock for spammers "reduces automation significantly and introduces more expensive and labor intensive processes (humans completing captchas) into the loop." ]

Trojan Exploits Adobe PDF Flaws, Installs Gozi Trojan (October 26 & 29, 2007)

A new variant of the Gozi Trojan exploits unpatched versions of Adobe Acrobat and Adobe Reader to infect machines. The Trojan arrives via maliciously crafted PDF files; the infected files download Gozi onto compromised computers. Gozi is designed to capture data entered when users visit secure websites. Users are urged to update to the most recent versions of Adobe Acrobat and Adobe Reader to protect their computers. PDF files are ubiquitous enough that people cannot be expected to stop using them. At least two groups are known to be launching the attacks.
-http://www.theregister.co.uk/2007/10/26/new_gozi_strain/print.html
-http://www.gcn.com/online/vol1_no1/45304-1.html?topic=security&CMP=OTC-RSS
-http://www.eweek.com/article2/0,1895,2209010,00.asp
[Editor's Note (Ullrich): This exploit was very predictable after a recent vulnerability disclosure. PDF readers are yet another one of those pesky web components which are often overlooked in patching but which are also exposed to untrusted content. ]

STATISTICS, STUDIES & SURVEYS

Higher Education Data Security (October 29, 2007)

CDW Government, Inc.'s third annual Higher Education IT Security Report Card found that although IT directors and managers in higher education say that data security is a high priority, there has been little improvement in actual data protection on college and university campuses. Fifty-eight percent of the campuses responding to the survey experienced at least one security breach in the last year. Furthermore, theft of staff and student data has increased 10 percent since last year's study, an increase of 43 percent.
-http://www.informationweek.com/shared/printableArticle.jhtml?articleID=202602868
[Editor's Note (Honan): Sadly the findings in this report also reflect the reality in many non-educational organisations. While information security is high on the IT manager's priority list, it appears this same urgency is often not reflected in the minds of senior business people. Being able to translate data security risks into business risks is a key skill information security professionals need to develop in order to ensure they receive the resources they require.
(Paller): Brian Honan's comment is exactly right. Security programs fail when the security manager cannot gain management support. That is why the SANS Master of Science degree candidates all spend a significant amount of time learning to present security topics in forms and language that will generate the management action they desire. You cannot ask security people to "translate security risks into business risks" if you don't teach them how to do it. ]

MISCELLANEOUS

Unflattering Details Emerge in TJX Case (October 28 & 29, 2007)

More details are surfacing about the TJX data security breach through documents filed in federal court. TJX was found to be non-compliant with the Payment Card Industry Data Security Standard, (PCI DSS), failing to meet nine of 12 requirements; a data thief managed to transfer more than 80 GB of TJX data without TJX noticing, and in May 2006, attackers placed a sniffer program on the TJX network that went undetected for seven months. In addition, Visa International has fined TJX's card processor, Fifth Third Bank, nearly US $900,000 for "egregious" security violations.

Graphics Processing Unit Cuts Password Cracking Time (October 24, 2007)

Russian software company Elcomsoft has filed a US patent for a password cracking technique that uses easily obtainable computer graphics hardware. The technique employs a graphics processing unit (GPU) from nVidia that has "massively parallel processing" capabilities.
