The above link redirects to GitHub. In the SANS-SEC505 folder there is a zip file containing folders named after each day of the SEC505 course. In the SANS-Slides folder in GitHub you'll find the evening presentations by Jason Fossen too, such as the "Windows Exploratory Surgery with Process Hacker" talk. There are hundreds of PowerShell and VBscript scripts in the zip file.
On Twitter and LinkedIn, follow @JasonFossen to receive alerts for new SEC505 PowerShell scripts and blog postings related to Windows security.
