🎯 Meterpreter vs Modern EDR

This blog post explains how making minor adjustments to the Meterpreter shellcode dropper can effectively evade modern EDRs. Three modifications are employed on the Meterpreter reference dropper. These modifications involve encrypting the Meterpreter shellcode using the XOR algorithm, incorporating valid metadata via a manifest file, and relocating the Meterpreter shellcode from the .text section to the .data section.

⚙️ MultiDump

This is a post-exploitation tool written in C for dumping and extracting LSASS memory discreetly. MultiDump supports LSASS dump via ProcDump.exe or Comsvc.dll, it offers two modes: a local mode that encrypts and stores the dump file locally, and a remote mode that sends the dump to a handler for decryption and analysis

🖥 Stealthy Shellcode Injection: Exploiting Windows Fork API for Memory Manipulation

Abusing Windows fork API and OneDrive.exe process to inject the malicious shellcode without allocating new RWX memory region. This technique is finding RWX region in already running processes in this case OneDrive.exe and Write shellcode into that region and execute it without calling VirtualProtect, VirtualAllocEx, VirtualAlloc.

🚀 Steps:

— Find the OneDrive.exe in running processes;
— Get the handle of OneDrive.exe;
— Query remote process memory information;
— look for RWX memory regions;
— Write shellcode into found region of OneDrive.exe;
— Fork OneDrive.exe into a new process;
— Set the forked process's start address to the cloned shellcode;
— Terminate the cloned process after execution.

🌀Voidgate

A technique that can be used to bypass AV/EDR memory scanners. This can be used to hide well-known and detected shellcodes by performing on-the-fly decryption of individual encrypted assembly instructions, thus rendering memory scanners useless for that specific memory page.
