Delving deep into VBScript
In late April we found and wrote a description of CVE-2018-8174, a new zero-day vulnerability for Internet Explorer that uses a well-known technique from the PoC exploit CVE-2014-6332. But whereas CVE-2014-6332 was aimed at integer overflow exploitation for writing to arbitrary memory locations, my interest lay in how this technique was adapted to exploit the use-after-free vulnerability.

Right from the beginning the reaction of various security professionals was negative. And we were right, it didn’t take long before the first ransomware variants arrived based on the hidden tear source code. Read Full Article
On the trail of Stagefright 2
In early October, it was announced that a critical vulnerability had been found in the libutils library. Although exploits for newly discovered vulnerabilities take a while to appear ‘in the wild’, we believe we should be prepared to detect them even if there have been no reports, as yet, of any such exploits being found. Because of this, we decided to do the research and generate a PoC file on our own. Read Full Article

ASP.NET Holiday Patches
It’s the end of 2011 as we know it, and Microsoft feels fine finishing out the year with a handful of out-of-band holiday patches. This round is important not because the vulnerabilities directly impact massive numbers of customers and their online behavior on Windows laptops, tablets, and workstations, but because ASP.NET maintains vulnerable code allowing for easy DoS of hosting websites, authentication bypass techniques, and stealth redirections to other websites (most dangerously those sites host phish and hosting client side exploits). All of this could curdle your eggnog in the coldest of weather. Read Full Article
