Deepsea Obfuscator V4 Unpack ((link)) Info

DeepSea Obfuscator v4 can typically be unpacked and deobfuscated using the open-source tool de4dot, which supports string decryption and removing proxy calls . For advanced, virtualized versions, a memory dumper may be required before applying de4dot to restore the .NET assembly . For a video demonstration of this process, visit YouTube .

  1. Locate the ResourceManager in the dumped assembly.
  2. Set a breakpoint on Assembly.GetManifestResourceStream.
  3. Dump the stream after decryption into a separate file.
  4. Re-insert the decrypted resources using mono-cecil or ILRepack.

Phase 2: Dumping the Unpacked Image

  1. Load the sample into x64dbg (if native) or directly into dnSpy if it loads.
  2. Set a breakpoint on kernel32!VirtualAlloc and kernel32!WriteProcessMemory.
  3. Run the binary. It will allocate a buffer and write the decrypted PE image.
  4. Once the buffer is written, dump the memory region using scyllaHide or manually.
