Credential Data Transfer via Network Shares
This rule detects the transfer of sensitive files containing credential data over network shares. It specifically looks for filenames or paths commonly associated with credential dumping, such as 'mimidrv', 'lsass', 'windows\minidump\', 'hiberfil', 'sqldmpr', 'sam', 'ntds.dit', and 'security'. This activity often indicates an attempt to exfiltrate credentials after they have been dumped from a system.
