SpookFlare gives you the opportunity to bypass the endpoint countermeasures at the client-side detection and network-side detection. SpookFlare is a loader generator for Meterpreter Reverse HTTP and HTTPS stages. SpookFlare has custom encrypter with string obfuscation and run-time code compilation features so you can bypass the countermeasures of the target systems like a boss until they “learn” the technique and behavior of SpookFlare payloads.

@tiraniddo released slides, demo videos, and some source code from his Zero Nights 2017 talk: Abusing Access Tokens for UAC Bypasses. Get it on his Github.
Summary:
“UAC, specifically Admin-Approval mode, has been known to be broken ever since it was first released in Windows Vista. Most of the research of bypassing UAC has focused on abusing bad elevated application behavior, auto elevation or shared registry and file resources. However, UAC was fundamentally broken from day one due to the way Microsoft implemented the security around elevated processes, especially their access tokens. This presentation will go into depth on why this technique works, allowing you to silently gain administrator privileges if a single elevated application is running. It will describe how Microsoft tried to fix it in Windows 10, and how you can circumvent their defences. It will also go into detail on a previously undocumented technique to abuse the assumed, more secure, Over-The-Shoulder elevation on Windows 10.”
Haider Mahmood has a nice write-up on his blog using a few different techniques to backdoor PE files, making them (hopefully) fully undetectable by anti-viruses. Some restrictions he used in the process were: not changing the functionality of the program itself , or increasing the file size, and avoiding using other common techniques like msvenom, veil, and other crypters/packers. The techniques he covers to help reduce the AV detection rate are, changing the PE’s section header, codecaves, and dual code caves. He goes over the pros and cons of each usage.
