I’ve play around with Java Deployment Toolkit exploit last week and found that the exploit is damn easy to trigger, but mitigation is a bit tricky (for Firefox especially if you have multiple version of Java installed)

Anyway, the patch released and people dont have to worry much about this anymore.

I’ve wrote a short analysis on the exploit (sample taken from the wild) and soon to be published in the Lebahnet Blog (pending for review). I’ve also wrote Yara rule to detect this exploit and it can be used with Jsunpack for automated analysis 🙂 owh.. I’ll publish the rule soon 😉

Many people are talking about this exploit including this blog. By the time I read through the content, I’ve found that they had published a non-valid code (maybe due to improper de-obfuscation or error during copy and paste for the entry). I’ve left 2 comments, correcting 2 lines of code in the entry. They made the changes but delete my comments (poor me, no credit :P)

Insyaallah I’ll publish the Yara rule by tomorrow 🙂
