How can credentials be extracted when download file size is restricted?

If downloading a large dump file is not feasible, you can repackage mimikatz to run entirely on the target system. SafetyKatz is a popular tool that obtains the lsass.exe dump, extracts credentials from it, and deletes the dump file—all on the target. The modified version supports .NET 3.5 and can be compiled with csc.exe. This approach avoids transferring large files over the network. For more details, refer to the original article.
