SharpSecDump

.Net port of the remote SAM + LSA Secrets dumping functionality of impacket's secretsdump.py. By default runs in the context of the current user. Please only use in environments you own or have permission to test against :)

Usage

SharpSecDump.exe -target=192.168.1.15 -u=admin -p=Password123 -d=test.local

Required Flags

• -target - Comma seperated list of IP's / hostnames to scan. Please don't include spaces between addresses. Can also dump hashes on the local system by setting target to 127.0.0.1.

Optional Flags

• -u - Username to use, if you want to use alternate credentials to run. Must use with -p and -d flags
• -p - Plaintext password to use, if you want to use alternate credentials to run. Must use with -u and -d flags
• -d - Domain to use, if you want to use alternate credentials to run (. for local domain). Must use with -u and -p flags
• -threads - Threads to use to concurently enumerate multiple remote hosts (Default: 10)

Notes

The project has been tested against Win 7,10, Server 2012, and Server 2016. Older versions (win 2003 / xp) may not work with this tool.

By default, if you're attempting to dump hives from your local system, you'll need to be running from a high-integrity context. However, this is not necessary when targeting remote systems.

This currently supports SAM + SECURITY registry hive dumping to retrieve cached credential data. However, it does not support NTDS.dit parsing / dcsync yet. If you're looking for dcsync functionality in a .Net project I recommend sharpkatz.

If a system is configured to disallow RPC over TCP (RPC over named pipe is required -- this is not a default setting) there is a 21s delay before Windows will fall back to RPC/NP, but will still allow the connection. This appears to be a limitation of using API calls that leverage the SCManager to remotely bind to services.

Credits

This code is a port of functionality from impacket by @agsolino and pypykatz by @skelsec. All credit goes to them for the original steps to parse and decrypt info from the registry hives.

The registry hive structures used are from gray_hat_csharp_code by @BrandonPrry.

Finally, the original idea for the script was based on a partial port I was working on of Posh_SecModule by @Carlos_Perez, a good chunk of initial SAM parsing code came from that project.
