This sample shows how to implement the IOfficeAntiVirus interface in C#

The resulting object, once registered, will calculate the file hash (SHA256/Sha1/MD5) for each file downloaded by Chrome, Edge, and Internet Explorer.

In order to successfully register this object, we'll use REGASM to register the assembly, then run a registry script to add the IOfficeAntiVirus
component category, and we'll delete the "Discardable\PostSetup" cache of known IOfficeAntiVirus implementations so that the next call to the IOfficeAntiVirus
providers will find our new object.

.SYNOPSIS

Decompresses a Windows Defender AV signature database (.VDM file).

.DESCRIPTION

Expand-DefenderAVSignatureDB extracts a Windows Defender AV signature database (.VDM file). This function was developed by reversing mpengine.dll and with the help of Tavis Ormandy and his LoadLibrary project (https://github.com/taviso/loadlibrary). Note: Currently, "scrambled" databases are not supported although, I have yet to encounter a scrambled database. Thus far, all databases I've encountered are zlib-compressed.

function Subvert-CLRAntiMalware {
<#
.SYNOPSIS

A proof-of-concept demonstrating overwriting a global variable that stores a pointer to an antimalware scan interface context structure. This PoC was only built to work with .NET Framework Early Access build 3694.

.DESCRIPTION

clr.dll in .NET Framework Early Access build 3694 has a global variable that stores a pointer to an antimalware scan interface context structure. By reading the pointer at that offset and then overwriting the forst DWORD, the context structure will become corrupted and subsequent scanning calls will fail open.
