A blog post on how to update the nmap-mac-prefixes file to improve nmap's OUI detection and provides a script to help streamline the process.
Blog post explaining how-to extract the OUI information from a MAC address and lookup the manufacture using public data from the IEEE.
A demonstration on how to use LD_PRELOAD to create a backdoor in processes by hooking the accept() function.
A post on how-to write NMAP version service probes via the nmap-service-probes file.
Overview In the last blog post in this series, we created a tool to make it easy to build our custom payloads and extract them. However, what if we...
Overview In the last blog post of the X86 Linux assembly series, we focused on how to make our Hello World payload friendly for use as a payload in...
Overview In the last two tutorials, we built a Hello World program in NASM and GAS for x86 assembly. While this can help us learn x86 assembly, it...
Overview In the last tutorial, we covered how to build a 32-bit x86 Hello World program in NASM. Today, we will cover how to do the same thing, but...
Overview A processor understands bytecode instructions specific to that architecture. We as humans use mnemonics to make building these instructions...
Overview The Intel x86 CPU architecture is one of the most prolific CPU architectures for desktops, laptops, and servers. While other architectures...
Today I want to continue the series on using LD_PRELOAD. In previous posts, we covered how to inject a shared object binary into a process, and...
NMAP is a wonderful network scanner and its ability to log scan data to files, specifically XML, helps quite a bit. This enables the scan data to be...
