Bypass AV via Change Filenames/Extension

You need to change the files extension:
.eyb files as .exe
.faq files as .dll

Use the following commands:
reg add HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.eyb /f /ve /t REG_SZ /d exefile
reg add HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.eyb /f /v "Content Type" /t REG_SZ /d "application/x-msdownload"

This can also work on other security solutions and for many other blacklisted techniques.

Small project of mine that is designed to move Cobalt Strike (or any really) beacon image, and heap, from memory to GPU memory before going to sleep. And moves everything back at the same place after sleep.

• Allocate_With_Syscalls — It uses NTDLL functions directly with the ntapi Library
• Create_DLL — Creates DLL and pops up a msgbox, Rust does not fully support this so things might get weird since Rust DLL do not have a main function
• DeviceIoControl — Opens driver handle and executing DeviceIoControl
• EnableDebugPrivileges — Enable SeDebugPrivilege in the current process
• Shellcode_Local_inject — Executes shellcode directly in local process by casting pointer
• Execute_With_CMD — Executes cmd by passing a command via Rust
• ImportedFunctionCall — It imports minidump from dbghelp and executes it
• Kernel_Driver_Exploit — Kernel Driver exploit for a simple buffer overflow
• Named_Pipe_Client — Named Pipe Client
• Named_Pipe_Server — Named Pipe Server
• Process_Injection_CreateThread — Process Injection in remote process with CreateRemoteThread
• Unhooking — Unhooking calls
• asm_syscall — Obtaining PEB address via asm
• base64_system_enum — Base64 encoding/decoding strings
• http-https-requests — HTTP/S requests by ignoring cert check for GET/POST
• patch_etw — Patch ETW
• ppid_spoof — Spoof parent process for created process
• tcp_ssl_client — TCP client with SSL that ignores cert check (Requires openssl and perl to be installed for compiling)
• tcp_ssl_server — TCP Server, with port parameter(Requires openssl and perl to be installed for compiling)
• wmi_execute — Executes WMI query to obtain the AV/EDRs in the host
• Windows.h+ Bindings — This file contains structures of Windows.h plus complete customized LDR,PEB,etc.. that are undocumented officially by Microsoft, add at the top of your file include!("../bindings.rs");
• UUID_Shellcode_Execution — Plants shellcode from UUID array into heap space and uses EnumSystemLocalesA Callback in order to execute the shellcode.
