[Monthly review] July 2018

I would like to start the monthly review to keep track my journey into Cybersecurity and Pentesting. I think the most important things I have done last month (July 2018) were start practicing on Hack The Box and join the local Pwn School meetup.

I have some things which I like and dislike about Hack The Box. At the beginning, I chose Hack The Box over Vulnhub was Hack The Box lists all of its labs/machines along with their difficulty level. That help me a lot as a beginner in Pentesting and I decided to hack all of its Easy labs first. I already finished Legacy and Blue, and stuck at Lame because I can't escalate my privilege from daemon user to root user. Now, I'm reading about Linux Escalation to overcome this obstacle. I also read the write-up and realized they used another vulnerability to hack this box. But, I want to learn and challenge myself so now I'm stopping at Lame. However, Hack The Box's lab not always available. So, I'm thinking about switching to Vulnhub.

Dallas Fort Worth has an amazing cybersecurity/hacking community. I met with some experts and gurus like wirefall, Phil, c0mmand3r, whiskey, Jay... And I expect to meet more. So let keep going to local meetup as much as I can.

Yeah, my last month was like that. I think I had a good start and keep trying and learning everyday.

[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 ...

[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 --> ...
