By default PowerShell is configured to prevent the execution of PowerShell scripts on Windows systems. This can be a hurdle for penetration testers, sysadmins, and developers, but it doesn't have to be.

I'm sure there are many techniques that I've missed (or simply don't know about), but hopefully this cheat sheet will offer a good start for those who need it. What is the PowerShell Execution Policy? The PowerShell execution policy is the setting that determines which type of PowerShell scripts (if any) can be run on the system. By de…

Hello Community,I have recently opened up a site where I post "lessons" about assembly and reverse engineering. The main purpose of the site is to help people interested in assembly and reverse engineer get started and learn the fundamentals. I have seen a lot of assembly/RE tutorials and none of them try to make it simple and easily understandable. In my website, that is what i also really focus on. I want the readers to learn but not make it to hard on them.I think reverse engineering is a great skill, as you can use to to debug your own programs or even use it to exploit programs (make hacks,keys,etc..)If you guys are interested, the site is completely free and easy to…
