Information Security is a strange field. There are probably few professions with such a wide range of social skills and preferences as the information security profession. Personally, I think this is what’s fun. It’s pretty cool that an MC can take a shot of vodka before introducing a speaker at a conference. Unfortunately, the perceived […]
Meterpreter’s getsystem command is taken for granted. Type getsystem and magically Meterpreter elevates you from a local administrator to the SYSTEM user. What’s really happening though? The getsystem command has three techniques. The first two rely on named pipe impersonation. The last one relies on token duplication. Let’s go through them: Technique 1 creates a […]

Read on for a sense of what I mean by this. Pivot Listeners This Cobalt Strike update introduces pivot listeners. A pivot listener is a handler for a reverse payload […]
If you’ve ever had to change a module in the Metasploit Framework, you know the go to place is the modules/ directory off of the Metasploit Framework’s root folder. Recently, I had to modify the Metasploit Framework’s reverse_http stager. It currently sends a blank User-Agent. This is a problem because a blank User-Agent will not […]
