Capabilities in Linux are special attributes that can be allocated to processes, binaries, services and users and they can allow them specific privileges that are normally reserved for root-level actions, such as being able to intercept network traffic or mount/unmount file systems. If misconfigured, these could allow an attacker to elevate their privileges to root.
Read moreThis was an intermediate Linux box that involved exploiting a PHP deserialization vulnerability to gain initial access, and a vulnerable Bash script to overwrite the root user’s authorized SSH keys and escalate privileges.
Read moreThis was an easy Windows box that involved exploiting an open FTP server to upload an ASPX shell and gain remote access to the host, and the MS10-015 KiTrap0D vulnerability to escalate privileges to SYSTEM.
Read moreAs the name suggests, this was a really simple challenge that involved accessing an open SMB share to identify usernames, performing a SSH brute-force attack to obtain access, and cracking the passphrase for a world-readable SSH key to escalate privileges.

Read moreThis was an easy Linux machine that involved exploiting a vulnerability in MSFVenom to gain remote code execution, a misconfigured Bash script to escalate to the “pwn” user, and a Sudo rule to escalate privileges to root.
Read moreNetwork File System is a protocol that allows users to access files over a computer network much like local storage is accessed, like many other protocols, it builds on the Open Network Computing Remote Procedure Call (ONC RPC) system. If misconfigured, it could allow regular users to escalate privileges to root.
