The first step in any 7z analysis is inspecting the archive metadata and attempting extraction.
: Use file donut.7z to confirm it is a valid 7-Zip archive. donut.7z
: If the 7z contains a loader, use a debugger like x64dbg to find where the shellcode is decrypted in memory. The first step in any 7z analysis is
: It is a tool used to create shellcode from .NET assemblies, VBScript, or JScript. donut.7z
: Run the extracted executable in a sandbox (like Any.Run ) to see if it attempts to call out to a Command & Control (C2) server.
: Use CyberChef to check for Base64 encoding or XOR operations frequently used in Donut loaders.
