Shady Rat Attackers Hid Code in Digital Images

More information about last week’s “Shady Rat” hacks continues to be uncovered, including reports that the attackers behind the hack used digital images to obscure their activities.Researchers at Symantec analyzing the attacks found images were hiding code that enabled communication back and forth with infected machines and a command-and-control (C&C) server, according to a report from DarkReading.

New Workaround Released For iOS SSL Flaw

A security researcher has released a new workaround for the critical vulnerability in the Apple iOS operating system related to the way that the OS handle SSL certificate validation. The workaround makes some key checks in the certificate chain that the vulnerable versions of iOS and a previous workaround fail to execute.


During the Reagan Administration, the ‘government waste’ meme was all about $600 toilet seats and $300 hammers. Those looking for a more contemporary example of how government procurement gets it wrong might point, instead, to Project 25 (P25), a decade old effort to provide first responders and federal officials with a reliable and secure emergency radio system.

A security researcher known for his work on cracking cryptographic ciphers on mobile networks has found a method that enables him to capture and decrypt data traffic on virtually any GPRS network. The attack, developed by Karsten Nohl, enables him to eavesdrop on traffic within a radius of about three miles.

LAS VEGAS–Researchers from IBM’s ISS X-Force plan to unveil a new system for running an open wireless network in a secure mode at the Black Hat conference here this week. The system mimics the way that Web sites browsers use digital certificates to establish a trusted connection with one another.

EMC Corporation announced via an earnings call Tuesday that it
spent $66 million during the second quarter on its security firm division RSA to
recover from a cyberattack that compromised their SecurID product in March,
according to a post on the Washington Post’s Post Tech blog.

Apple has released another new version of its iOS operating system for iPhones and other devices that fixes a security vulnerability in the way that the software handled SSL certificates and validated their authenticity. An attacker exploiting the bug might be able to intercept SSL traffic, Apple warned.

Apple has released the newest version of its OS X operating system, dubbed Lion, and it includes a batch of new security protections that bring it up to the level of Windows and Internet Explorer. The most significant additions, experts say, is the full implementation of ASLR and a sandbox that make it much more difficult for attackers to exploit browser bugs via a drive-by download to install malware on a victim’s machine.

A group of researchers from the University of Michigan and the University of Waterloo have developed a proxy system called Telex that provides a method for users to circumvent state-level censorship of the Web. It uses an architecture that includes a proxy at the ISP level and uses connections to benign sites to disguise traffic going to censored sites. Threatpost editor Dennis Fisher spoke with J. Alex Halderman, one of the creators of the system, about its potential, its limits and what remains to be done before it can be deployed broadly.
