: Use strings to look for API calls like VirtualAlloc , WriteProcessMemory , or CreateRemoteThread , which indicate process injection. 4. Reverse Engineering Steps
: It is a tool used to create shellcode from .NET assemblies, VBScript, or JScript.
Example: 7z2john donut.7z > hash.txt followed by a dictionary attack. 3. Payload Investigation (Donut Shellcode) donut.7z
: Use CyberChef to check for Base64 encoding or XOR operations frequently used in Donut loaders.
If the archive contains a binary related to the "Donut" project, you are likely dealing with a position-independent shellcode generator. : Use strings to look for API calls
: Use file donut.7z to confirm it is a valid 7-Zip archive.
: Run the extracted executable in a sandbox (like Any.Run ) to see if it attempts to call out to a Command & Control (C2) server. Example: 7z2john donut
: If the archive is encrypted, tools like John the Ripper or hashcat are used.
