Research Shows Half of All Androids Contain Known Vulnerabilities

About half of all Android phones contain at least one vulnerability that could be used to take control of the device, according to new research. Duo Security, which launched a free vulnerability scanning app for Android this summer, said their preliminary data from users shows a huge number of the devices are vulnerable to at least one of the known Android flaws.

Apple Fixes Huge Number of Flaws With iTunes 10.7

Apple has released a massive security update for iTunes on Windows, fixing more than 160 security vulnerabilities. The new version of iTunes is one of the larger security updates by any vendor in the last few years, and many of the fixes are for WebKit vulnerabilities.

CRIME Attack Uses Compression Ratio of TLS Requests as Side Channel to Hijack Secure Sessions

The new attack on TLS developed by researchers Juliano Rizzo and Thai Duong takes advantage of an information leak in the compression ratio of TLS requests as a side channel to enable them to decrypt the requests made by the client to the server. This, in turn, allows them to grab the user’s login cookie and then hijack the user’s session and impersonate her on high-value destinations such as banks or e-commerce sites.


Security researchers Juliano Rizzo and Thai Duong have developed a new attack called CRIME on the TLS protocol that uses the compression ratio in TLS requests as a side channel to gather information that enables them to decrypt the requests and extract users’ cookies.

The developer behind the notorious Black Hole exploit kit has released a new version of the software, adding in several new features designed to prevent security researchers from getting access to new exploits or reverse-engineering the kit’s inner workings. Conveniently, the pricing for Black Hole has stayed the same, so hackers get more value for the same amount of money.

SAS70 Needs to Die

By Andrew Storms

Let’s be clear, SAS70 should be sentenced to a quick and painful death in the bottom of a giant pit protected by 20-foot thick concrete walls where it should be buried forever, along-side other IT criminals such as Windows ME and IE6.

Saudi Aramco says that the virus attack that compromised tens of thousands of the company’s workstations last month never endangered the company’s oil production capabilities and that all of the affected systems have been brought back online and restored. The attack on Aramco has been linked by researchers to the Shamoon malware, but company officials did not comment on the nature or provenance of the malware.

UPDATE–The same team that attacked Google in the Aurora campaign in 2009 is still active and has been conducting a long-term campaign targeting defense contractors, financial services companies, energy companies, human rights organizations and government agencies using a seemingly inexhaustible supply of zero day vulnerabilities. The crew is using a variety of techniques to go after its targets, most notably compromising legitimate Web sites frequented by employees of the targeted organizations and then delivering exploits for one or more of their stockpiled zero-day bugs, researchers say.

Huawei, the massive Chinese technology company that has come under criticism for its close ties to China’s government, is defending itself, saying that it has never stolen national intelligence or intellectual property and does not support any groups that do so. The company has been a frequent target of critics who allege that it trades information and secrets with the Chinese government, allegations its officials have consistently denied.
