After our recent blog post about an encrypted Flash exploit, we went back to analyze some more of these exploit files. We took some of the newer exploit recordings available on a malware aggregation site, and tried to decrypt them using the same...

One of our favorite things to do is to reproduce exploits in our research labs. We do this for two main reasons: first, because we are naturally curious, and second, to constantly ensure that our solution prevents these exploits natively (spoiler:...
