🔧 Technical Details

Command-output exfiltration (“print-exfiltration”) for shells without file transfer: If you have remote command execution and can read stdout (e.g., via a web shell) but cannot upload/download files, you can still exfiltrate by (1) archiving target files (e.g., with WinRAR), (2) converting the archive/file to Base64 text using certutil -encode, then (3) returning the Base64 over the interactive channel using type. The attacker reconstructs the original file offline by decoding Base64. This abuses the fact that many monitoring stacks treat command output as lower-risk than explicit file transfer.

DLL side-loading with a legitimate interpreter to execute in-memory payloads: Place a legitimate executable (here, python.exe/
