In this talk, we present CheckPlease, our new repository of implant security modules. CheckPlease is unique in that it is payload-agnostic, meaning we implement every module in PowerShell, Python, Go, Ruby, C#, Perl, and C. In our talk, we not only present on a breadth of new techniques, but we also walk step-by-step through their implementations in newer languages that are seemingly a major increase in payload deliverance.
CheckPlease will serve as the central repository for implant security and, as a byproduct, sandbox detection. In our opinion, the future of sandbox detection is in implant security; by targeting your payload, your odds of executing in a sandbox decrease dramatically. This talk will provide insight into the newest implant security techniques, their implementations, and how payloads in new languages interact with the Windows API.
