SMBMap allows users to enumerate samba share drives across an entire domain. List share drives, drive permissions, share contents, upload/download functionality, file name auto-download pattern matching, distributed file content pattern scanning, and even remote command execution. This tool was designed with pen testing in mind, and is intended to simplify searching for potentially sensitive data across large networks. It is also very helpful to identify gaps in permissions, which is a critical network issue that is largely overlooked due to the lack of tools available to simplify this task. Until now :).
Found a ton of bugs. Hopefully cleared up, but things just keep cropping up. Distributed search seems to be working pretty well after a few (major) hiccups.
