Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

BEST KALI TOOL TO MAKE UNDETECTABLE BACKDOOR 2022?
syswhispers2 -- tool for helping unhook userland hooks by reimplementing syscalls. Basically just generates a header file; you still have to write the loader yourself.
- Syswhispers2 - AV/EDR evasion via direct system calls.

Are the logs from all .evtx and .etl files included with Get-EventLog and Get-WinEvent?
Yes, and based on this table sysmon actually causes additional events to be generated (although I think it is hooking high level APIs, so I think a technique like SysWhispers might cause some of these events to be invisible through Sysmon) so that could be useful even if we're not focused on the GUI. Writing my own ETW consumer / providers is a little advanced for me right now, so that's cool.

Can't do exploitation research on a novel unhooking approach without a database of the DLLs for every Windows version. Ideas?

Obfuscating powershell beacons
If you wanna stay with unmanaged code look into https://github.com/jthuraisamy/SysWhispers2 I'm a noob with native languages so can't say how effective it is. It also has a downside including ASM references to the binary that are unusual and might be detected, not sure on this tho.

https://github.com/JustasMasiulis/inline_syscall (AFAIK the only library that produces inline-able syscall stubs)
What are some alternatives?
DInvoke - Dynamically invoke arbitrary unmanaged code from managed code without PInvoke.
lazy_importer - library for importing functions from dlls in a hidden, reverse engineer unfriendly way
etl-parser - Event Trace Log file parser in pure Python
Black-Angel-Rootkit - Black Angel is a Windows 11/10 x64 kernel mode rootkit. Rootkit can be loaded with enabled DSE while maintaining its full functionality.
HellsGate - Original C Implementation of the Hell's Gate VX Technique
ZwProcessHollowing - ZwProcessHollowing is a x64 process hollowing project which uses direct systemcalls, dll unhooking and RC4 payload decryption
Shhhloader - Syscall Shellcode Loader (Work in Progress)
Corth - It's like Porth, but in C++. Yep, we're going full circle.
ThreatCheck - Identifies the bytes that Microsoft Defender / AMSI Consumer flags on.
introvert
donut - Generates x86, x64, or AMD64+x86 position-independent shellcode that loads .NET Assemblies, PE files, and other Windows payloads from memory and runs them with parameters
