Full Disclosure: Malware analysis isn't my area of expertise, but I have been looking for chances to learn more. Let's learn together! I was recently describing to a friend how phishing attacks work, one of the most common ways being word documents with a macro to run or download malicious code. Sure enough, several weeks later the same friend received a phishing ... READ MORE

Taking One For The Team: The “Double Tailgate” Approach for Physical Pentests
When it comes to physical pentests, there are a variety of different approaches and techniques used depending on the environment and situation. While most people are familiar with the concept of tailgating in order to gain access to restricted areas, the double tailgate can be useful when the point of entry has tailgating detection mechanisms in place. The scenario where ... READ MORE
CYA: Cover Your Alfa (Part II)
Part II: Testing In the first part of this post I covered the basic steps I took to conceal an Alfa AWUS036H in an HDD enclosure. In this part I’ll cover the basic testing I did to see how that impacted its performance, as well as the results of those tests. The diversity of wireless cards, drivers, and programs can make it difficult to get honest comparisons between ... READ MORE

I've had a number of recent opportunities to conduct VoIP-focused penetration tests. Prior to my first, I noticed that the number of tutorials, blogs and training write ups are pretty scarce. So, I figured it might be helpful to have all of it in one place. In this short blog series, I'll cover the goals, methodology, and tools needed to conduct a successful VoIP penetration ... READ MORE
Evil Twin Attack Using hostapd-wpe
The Evil Twin Attack has been around for some time. In the past, when we've run across WPA/2 Enterprise Wireless networks while on assessments, we'd break out a separate router and sit in a parking lot or lunch room waiting for victims to pass. The attack was simple, but the setup was overly complicated and left us tied to a power outlet. Fortunately, all that is in the past. A ... READ MORE
Analyzing Safe Exception Handlers
SafeSEH (Safe Structured Exception Handlers) is a Windows binary protection mechanism for 32-bit executables that has been around for a while now. When the option is enabled, the linker creates a list of valid exception handler addresses in the SEHandlerTable when the binary is being built. This protection prevents the execution of corrupted exception handlers which is a common ... READ MORE

Understanding Radio Frequency Theory
I did a short series on attacking Wi-Fi for my personal blog last year, but I did not cover Enterprise Wireless. A few interesting tools have been released in the time that has passed, so I'm going to steal some of my own words as a short lead into a new post on conducting attacks against WPA/2-Enterprise wireless networks. The Spectrum Electromagnetic energy is the basis on ... READ MORE
Request to Exit Sensor Bypass

The exterior or public side, of these doors is often controlled by an Access Control System utilizing either a Prox or iClass card reader. Due to various fire codes and regulations, the secured side of these doors ... READ MORE
