Hack Microsoft Using Microsoft Signed Binaries

Imagine being attacked by legitimate software tools that cannot be detected by usual defender tools.
How bad could it be to be attacked by malicious threat actors only sending bytes to be read and bytes to be written in order to achieve advanced attacks?
The most dangerous threat is the one you can’t see. At a time when it is not obvious to detect memory attacks using API like VirtualAlloc, what would be worse than having to detect something like “f 0xffffe001`0c79ebe8+0x8 L4 0xe8 0xcb 0x04 0x10”?
We will be able to demonstrate that we can achieve every kind of attacks you can imagine using only PowerShell and a Microsoft Signed Debugger. We can retrieve passwords from the userland memory, execute shellcode by dynamically parsing loaded PE or attack the kernel achieving advanced persistence inside any system.
