It can perform rapid dictionary attacks against more than 50 protocols, including telnet, vnc, http, https, smb, several databases, and much more Now, we need to choose a word list. As you can observe that we had successfully grabbed the MSSQL password as [email protected] Medusa Medusa is intended to be a speedy, massively parallel, modular, login brute-forcer.
Just curious. That was a MITM box receiving redirected traffic, yes? I did not actually get the SA password. The victim was logged in as the SA account. Does that make sense? Yes you could do something more complicated to identify queries and replace them based on regular expressions or something similar. This was a proof of concept I wanted to get running quickly. I have a feeling that something like Python with Scapy could be used to do what you mentioned with minimal work.
This looks very interesting. I want to try this against SQL Server not available just yet. It has a new Always Encrypted feature which can encrypt seemlessly from client to server and back.
Cool article! And then fill the additional space with spaces. There are no stupid questions! I believe this could be done, but likely you would need to use other tools. I think to do something like you mentioned you would have to do a more manual process. Something like this:. Perform the arp spoofing attack manually 2. Forward SQL traffic to your own program which can perform the more complex regex functions and replace the query with a more variable length string.
Nice POC and a good argument for everybody, to take security borders and encryption more seriously. In a nutshell database security is such a matter of importance here and every application connecting to the database : applying security at the database level in terms of permissions and stuff, config files should be encrypted etc, this post is great from any angle but it might possible to be executed depending on the user permissions playing here, my two cents, again great post.
You should still be able to inject your own queries as long as the connection is unencrypted. The difference would be in the permissions of the authenticated user. You can only inject queries that the authenticated user has permission to run. This can still be a bad thing if the database contains sensitive information. Just curious, and want to make sure.
