    The first quarter of the year saw cybercrime hit targets that may not have been considered worthwhile in previous quarters. Multiple Bitcoin exchanges found themselves the victims of various attacks and were forced to close shop. The most high-profile victim Mt. Gox, which had been, at one time, the leading Bitcoin exchange in the world. Exchanges were not the only target. With more than 12 million Bitcoins in existence - with a value of 6-8 billion US dollars - it ...




    We've recently found a vulnerability in certain Android apps that may leave user data at risk of being captured or being used to launch attacks. The two affected apps we investigated are both highly popular: The productivity app has at least 10M installs and hundred thousands of customer reviews based on their download page The shopping-related app has at least 1M installs and several thousand customer reviews based on their download page This issue lies in a certain Android component which basically executes ...




    Vulnerabilities, particularly zero-days, are often used by threat actors as the starting point for targeted attacks. This was certainly the case for a (then) zero-day vulnerability (CVE-2014-1761) affecting Microsoft Word. In its security advisory released last March, Microsoft itself acknowledged that the vulnerability was being used in “limited, targeted attacks.” Microsoft has since patched this vulnerability as part of its April Patch Tuesday. However, the existence of a patch has not deterred threat actors from exploiting this vulnerability. We are still ...




    Last week, Adobe released an advisory disclosing a new zero-day vulnerability in Flash Player. Looking into the exploit code used in attacks targeting this vulnerability, we found several interesting ties to other vulnerabilities - not all of them for Flash Player, either. To explain this, we will discuss the highlights of how this exploit was performed. Exploit highlights At its core, the vulnerability is a buffer overflow that occurs when parsing a compiled shader in a Flash object. The overflow overwrites an adjacent memory buffer, ...

    The recent Internet Explorer and Flash zero-days were not the only zero-day threats that hit recently. Last Friday, the Apache Struts group released an advisory (S2-021) detailing two vulnerabilities (CVE-2014-0112 and CVE-2014-0113), and potential mitigation steps until an official patch is issued. Apache Struts is a framework used to build and deploy Java-based web applications. In Apache Struts2, most of the core functionality is implemented as Interceptors. These can execute code before and after an Action is invoked and each Interceptor can be ...
