[Tutorial] Cracking Windows 7 Password with Physical Access

Hi friends,

In some engagements, we can have a physical access to a Windows machine. So, today I'll try to simulate that situation on VMware virtual environment: cracking a Windows 7 password with Kali Linux live CD/DVD. I have to say clearly that I'll show how to crack the password, not change or reset or disable it.

I'll use the Windows 7 VMware image from Microsoft website to show you the steps below. Please download the virtual machine if you want: link.

Because the above Windows 7 is a 32 bit machine, we have to use the 32 bit Kali Linux.

1. Change the setting of the Windows 7 to use the Kali Linux 32 bit ISO file and choose "Connect at power on":


2. Power on the machine to firmware --> change the boot order --> Save change and reboot:



3. Now, we can boot the machine by Kali Linux, let's browse to the folder Windows\System32\config and open a terminal from that location:


4. From that terminal, fire up ophcrack --> Load --> Encrypted SAM --> Open:



5. Save the results to Desktop:


6. Open Firefox and use this website to crack the hash:


And we found the password is "Passw0rd!"

    Where do you get the menu for #2 Power on the machine to firmware?

[Metasploitable 2] Method #3: Bind Shell Backdoor

Hi friends, This post will be short because the vulnerability is very clear and straightforward. As you may know, on my 2nd post on Metasploitable 2 hacking , I used Nessus to confirm the vulnerability found by Nmap. The scan results from Nessus are very interesting! So let's just start by looking at the first one: Bind Shell Backdoor Detection. The detail of this vulnerability says very clear that the Metasploitable 2 machine's shell is listening on port 1524. So let's try to use netcat to connect to port 1524. That's easy, right? We also can see the connection from Kali to Metasploitable 2 on port 1524. Let's move to another way.

[Metasploitable 2] Method #1: Meet My Old Friend distccd v1

Hi friends, I would like to share with you how I hack Metasploitable 2 by utilize the distccd v1 vulnerability. These are many bugs in Metasploitable 2 that can help you to hack it. Why I choose distccd? After using NMAP to scan for open ports on Metasploitable 2, I think I might meet an old friend again. I faced up to distccd when playing with Hack The Box's Lame (you can read my write-up on box Lame here ). So, I guess I could use the same technique to hack Metasploitable 2 for the first time. Let's start! Using NMAP to scan for vulnerability on port 3632 :  nmap --script vuln -p3632 192.168.32.129 We got  CVE-2004-2687 ! Fire up Metasploit to search for the appropriate module or you can just use Google:  msf > search type:exploit name:distcc We know what module we have to use and then we can get in the box with the daemon user. How to become root? We have to find a way to escalate our privilege. Let's take a look on this article to know how ...
