Microsoft Warns On New Browser Vulnerability

Microsoft on Wednesday issued a security advisory to users of its Internet Explorer Web browser about a newly disclosed vulnerability that could be exploited and used to run malicious code on vulnerable Windows systems.


A french IT security firm is warning of a previously unknown (“zero day”) vulnerability that affects most versions of Microsoft’s Internet Explorer Web browser. The hole, if exploited, could allow remote attackers to circumvent defensive features in fully patched WIndows 7 and Windows Vista and run malicious code on vulnerable systems.

UPDATE: The Massachusetts Attorney General has been notified that financial data on 1,800 residents were exposed in a database breach linked to CitySights NY, a sightseeing firm. The case could set the stage for enforcement of the State’s nine month-old data privacy law.

HED: New Intel Chips Support SMS Kill SwitchDEK: Anti Theft 3 Chips Can be disabled via 3G NetworksNew computer processors from Intel Corp, due out in 2011, can be disabled using an SMS “poison pill” message sent over any 3G cellular network, according to Intel documentation.The new anti-theft feature, which Intel has dubbed “Anti Theft 3.0” will only be available for devices using Intel’s latest Sandy Bridge microprocessors. The new feature will enable organizations to remotely disable lost or stolen laptops even if those devices are not connected to the Internet. Instead Any device within range of a 3G cell tower could be disabled using what Intel describes as an “encrypted SMS” text message. The new feature comes as organizations are looking for ways to guard against data breaches that stem from lost or stolen mobile devices, one of the biggest sources of such breaches. Intel is planning to unveil the new chips at teh Consumer Electronics Show (CES) in Las Vegas in January. The addition of a 3G “kill switch” for Intel is just the latest evolution in its hardware-based anti theft technology and has been in the works for months. Intel already offers customers the ability to disable lost or stolen devices via LAN, wirless LAN and VPN connection. However, those methods require a lost or stolen device to be connected directly to the Internet first. The 3G poison pill feature would allow technicians to trigger one or more security features so long as the stolen or lost device checked in with a 3G tower. Options include disabling access to encrypted data by deliting an encryption key stored in the chipset, disabling the laptop by blocking the boot process or both, Intel said. The term “poison pill” may be misleading, however, as Intel’s Anti Theft features also allow users to re-enable the device after the anti-theft features have been enabled. Intel has made security a key investment area, as the company prepares for a post-PC world in which “pro-sumer” mobile devices running its processors increasingly operate outside of corporate firewall, carry a mixture of personal and corporate data and leverage both WiFi and 3G connections for Internet connectivity, voice, video and more. In August, Intel purchased anti malware firm McAfee for $7.68b in a surprise move. Intel said that it was interested in baking security deeper into its hardware and avoid the traditional performance slow downs that security software produces. The Sandy Bridge chip is the successor to the Nehalem architecture and is already being distributed to Intel OEMs. The anti theft features are just one improvement on the latest generation processors, along with improved performance, a boost in the capabilities of integrated graphics features.  New computer processors from Intel Corp, due out in 2011, can be disabled using an SMS “poison pill” message sent over any 3G cellular network, according to published reports.

As government agencies and the military bar access to the WIkileaks documents, a poll of Web filtering providers finds most label the leak site more “newsy” than “naughty.” 

HED: Wikileaks: Controversial, But is it NSFW?
DEK: As companies look to bar access to the WIkileaks documents (or not) Web filtering providers must decide how to categorize the leaked documents. 
The controversy surrounding leaked diplomatic cables prompting organizations to weigh whether or not to block access to the leaked documents. But a poll of prominent Web filtering firms by Threatpost suggests that most consider WIkileaks sites to be sources of “news and politics,” not suspicious and malicious Web sites that demand blocking or extra security. 
Employee access to the leaked documents became a headline issue this week after it was reported that the U.S. Air Force is blocking its computers ability to access not just the Wikileaks Web site and mirror sites, but also the Web sites of news organizations, including that of the New York Times and 25 other news websites, that published the classified documents. (http://www.nytimes.com/2010/12/15/us/15wiki.html). In an unrelated story, the operators of a prominent WikiLeaks mirror Web site found its domain classified as “suspicious” by anti spam group Spamhaus. (http://www.theregister.co.uk/2010/12/16/wikileaks_mirror_malware_warning_row/) As corporations and governments weigh their “position” on Wikileaks, Web content filtering firms find themselves on the front lines: providing the tools to block access to those sites and, in some cases, helping define exactly what WikiLeaks “is” and “is not.” Our poll shows that, while there’s no consensus on how to characterize Wikileaks and its mirror sites, most content monitoring firms are treating the leaks site as a source of news and information, but leaving it up to customers to decide for themselves. 
Writing for Blue Coat Systems, malware researcher Chris Larsen said that his company is “neutral” when it comes to classifying the Wikileaks content, saying that its customers make decisions about what content to allow or block their users from seeing. Wikileaks documents are no different from other classes of content – including porn: some customers will want to block it and others won’t. Blue Coat Webfilter categorizes Wikileaks and its mirror sites in two categories: Political/Activist Groups and News/Media. The former are described as “sites sponsored by or that provide information on political parties, special interest groups, or any organization that promotes change or reform in public policy, public opinion, social practice, or economic activities.” The latter, News/Media sites, are defined as “sites that primarily report information or comments on current events or contemporary issues of the day. This category also includes news radio stations and news magazines but does not include sites that can be rated in other categories,” according to Blue Coat. 
Blue Coat customers can create policies that target specific sites within those categories to avoid overblocking content, according to Jennifer Arculeo, a spokesperson at BlueCoat. 
Wikileaks and its mirrors are “News and Media” sites for security firm Fortinet, too, said Ken Lin, a member of Fortinet’s FortiGuard security team. 
Over at McAfee, Wikileaks and its mirrors are classified as “Politics/Opinions” sites – one of over 90 different categories that McAfee lets customers choose from. Customers can also add their own sites to the filter in accordance with their policies, the company said in an e-mail statement. 
A Cisco Systems spokesman said that organization didn’t categorize Wikileaks and its mirrors one way or the other, though that would change if they started pushing malicious code or other threats. The same was true of Kaspersky Lab, though the sites do run afoul of Kaspersky’s parental controls for frequent mentions of war and violence, said Andrey Nikishin, General Manager of Kaspersky’s Cloud & Content Technologies.
Calls to censor Wikileaks within the U.S. have escalated since the release of “Cablegate,” a collection of more than 200,000 pages of sensitive diplomatic cables. This week, U.S. Senator Joe Lieberman called publicly for investigations of news organizations that published the cables (http://thinkprogress.org/2010/12/07/lieberman-understand-doj-treason/), including The New York TImes, while other politicians suggested Wikileaks founder Julian Assange should be tried under an 80 year old “Espionage Act” in the U.S. A newly elected U.S. Representative from Florida, Allen West (R-Fort Lauderdale) was quoted saying that media organizations that published leaked documents should be censored (http://floridaindependent.com/17394/allen-west-calls-for-censoring-news-outlets-working-with-wikileaks), though West later said he meant to say “censured,” not “censored.” 

Authorities in Romania have disrupted a large hacking ring accused of stealing Voice over IP (VoIP) data from hacked servers and using it to place bogus calls to premium rate numbers. Agence France Presse reported on Tuesday that 42 people were arrested in the sting, breaking up a network that was headed by two Romanians and that had caused more than $13.5m in losses to firms in the U.S., Britain, South Africa, Italy and Romania.
