This is why we have nice things

Rawbytes is not the modifier you're looking for

I spend a lot of time working with Sourcefire customers and open-source Snort users who write their own custom rules. Many of them are extremely astute, and some of them write rules good enough to be in the official VRT set. Others, well, not so much. One of the biggest issues I

Do you really trust that certificate?

If you've read many of my posts on this blog, you've probably realized by now that I'm lazy when it comes to dealing with malware. I hate the "whack-a-mole" game of trying to stay on top of every new thing every new piece of malware does - not only because i

Razorback Roadmap and Status Report

In which we get our first introduction to Tom Judge, the Amish Hammer. Yep, you're right, we've been kinda quiet lately.  Some of that has been because we are the VRT in addition to the developers of Razorback and we had some big things to tackle in our other roles.  But

Lizamoon attacks and generic detection

You've probably heard by now of the "Lizamoon" attacks, a rapidly spreading bit of SQL injection named for the domain that hosted the script dropped onto a variety of pages across the web. While not a particularly interesting attack from a technical perspective, it&
