DC22 Talk: Killing the Rootkit

By Shane Macaulay I’ll  be at DefCon22 a to present information about a high assurance tool/technique that helps to detect hidden processes (hidden by a DKOM type rootkit).  It works very well with little bit testing required (not very “abortable” http://takahiroharuyama.github.io/blog/2014/04/21/memory-forensics-still-aborted/). The process  also works recursively (detect host and guest processes inside a host memory dump). Plus, I will also be at our IOAsis (http://ioasislasvegas.eventbrite.com/?aff=PRIOASIS) , so come through for a discussion and a demo.

Common Coding Mistakes – Wide Character Arrays

This post contains a few of my thoughts on common coding mistakes we see during code reviews when developers deal with wide character arrays. Manipulating wide character strings is reasonably easy to get right, but there are plenty of “gotchas” still popping up. Coders should make sure they take care because a few things can slip your mind when dealing with these strings and result in mistakes. A little bit of background: The term wide character generally refers to character data types with a width larger than a…

Windows Vulnerability Paradox

For those who read just the first few lines, this is not a critical vulnerability. It is low impact but interesting, so keep reading.   This post describes the Windows vulnerability I showed during my Black Hat USA 2011 workshop “Easy and Quick Vulnerability Hunting in Windows”.   The Windows security update for Visual C++ 2005 SP1 Redistributable Package (MS11-025) is a security patch for a binary planting vulnerability. This kind of vulnerability occurs when someone opens or executes a file and this file (or the application used to…

Arm IDA and Cross Check: Reversing the 787’s Core Network

IOActive has documented detailed attack paths and component vulnerabilities to describe the first plausible, detailed public attack paths to effectively reach the avionics network on a 787, commercial airplane from either non-critical domains, such as Passenger Information and Entertainment Services, or even external networks.
