This was an intermediate-level Linux machine that involved brute-forcing WordPress credentials to gain initial access through a malicious plugin upload and escalating privileges through a Jenkins instance with weak credentials.
Read moreThis was an intermediate Linux machine that involved exploiting a SQL injection vulnerability to gain initial access, a misconfigured Python script to escalate to the “pepper” user and the Systemctl binary with SUID privileges set to escalate to root.
Read moreThe Offensive Security Wireless Professional is an ethical hacking certification offered by Offensive Security that teaches wireless penetration testing techniques, specifically for WEP, WPA, and WPA2.
It comes with the Offensive Security Wireless Attacks video and PDF course, which aims to prepare students for the exam. In this article, I take the time to talk about my experience with this certification, the pros and cons of the course, thoughts after taking and passing the exam, etc.
Read moreThis was an intermediate Linux machine that involved exploiting the ticket reply via email functionality of osTicket to access a MatterMost web application to find SSH credentials and using Hashcat rules to crack root hashes stored in the MySQL database to escalate privileges.
Read moreThis was an easy Windows machine that involved exploiting the Microsoft Eternal Blue exploit to gain immediate system-level access or alternatively an open SMB share to gain initial access and token impersonation to escalate privileges to system.
Read moreThis was an intermediate Linux machine and the last in the Overpass TryHackMe series, it involved discovering a backup archive stored on the webserver, which contained encrypted user credentials that are then used to connect to the FTP server and uploading a PHP reverse shell to gain initial access. Root access was then obtained by exploiting an open NFS share with the no_root_squash option enabled.
Read moreThis was an easy Linux machine and the second in the Overpass TryHackMe series. It involved analyzing a capture file containing requests issued by an attacker to compromise the web server, escalate privileges to root and establish persistence, in order to understand the exact steps followed to do so, and then using that information to hack back into the host.
Read moreThis was an intermediate Linux machine that involved exploiting a remote code execution vulnerability in the CuteNews web application to gain initial access, exposed user password hashes to gain a user shell, and a vulnerability in the USBCreator D-Bus interface to escalate privileges to root.
Read moreThis was an intermediate Linux machine that involved exploiting a remote code execution in GitLab to gain initial access, an exposed root password and a misconfigured docker container to escalate privileges to root.
