Mimikatz is an open source Windows utility available for download from GitHub. First developed in 2007 to demonstrate a practical exploit of the Microsoft Windows Local Security Authority Subsystem Service, or LSASS, Mimikatz is capable of dumping account login information, including clear text passwords stored in system memory.
mimikatz -- French for cute cat -- is a post-exploitation tool intended to help attackers -- whether black hat hackers, red team hackers or penetration testers -- to extract login IDs, passwords and authentication tokens from hacked systems in order to elevate privileges and gain greater access to systems on a breached network.
In this tutorial, we'll look at how we can crack the password on the system admin (sa) account on the database, install a meterpreter payload through calling the stored procedure xp_cmdshell, and wreak havoc on their system.
BackTrack has a wordlist specially built for MS SQL password hacking with over 57,000 commonly used SQL passwords at /pentest/exploits/fasttrack/bin/wordlist.txt. In this case, our target is at 192.168.1.103, and we will set our THREADS to 20.
As you can see, after testing over 57,000 passwords (it takes a few minutes, so be patient), it found the password on our sa account of "NullByte". Success! Now we have full sysadmin privileges on the database that we can hopefully convert to full system sysadmin privileges.
If you logged in to your root account using a password, then password authentication is enabled for SSH. You can SSH to your new user account by opening up a new terminal session and using SSH with your new username:
You get a lot of unwanted emails, such as subscriptions or promotional offers. A hacker tries to fill up your Inbox so that you can't find important security alerts from websites or services you signed up for with your Gmail account.
Probably one of the most sought-after features of all SAM tools but is not a feature that any of them can provide consistently. There is a great reason for this: if a SAM tool can discover it, so can a hacker. From decades ago, keys were made private and not discoverable. Some products are less secure, putting their keys visible in clear text in the registry or in license files. But most are encrypted, scrambled, or otherwise not readable. Especially as more software goes subscription and employs cloud activation (a username and password vs a key), this is a losing battle for us SAM analysts. 2b1af7f3a8
