Xenon is a Windows agent designed for the Mythic framework, inspired by tools like Cobalt Strike.
It is currently in an early stage of development and is not considered operationally secure (OPSEC safe), meaning it may contain memory leaks and other issues that could lead to crashes.
Despite these limitations, Xenon offers several features that make it useful for testing and educational purposes.
Key Features Of Xenon
- Modular Command Inclusion: Xenon allows users to include commands in a modular fashion, making it easier to extend its functionality.
- Malleable C2 Profiles with HTTPX: Xenon supports malleable command and control (C2) profiles using the HTTPX framework. This allows operators to configure how the agent communicates with its server, including features like domain rotation, callback jitter, and message transforms.
- Compatibility with Cobalt Strike BOFs: Xenon can execute Beacon Object Files (BOFs) from Cobalt Strike, providing additional situational awareness capabilities.
Xenon includes a range of basic commands for file management and process interaction:
- pwd: Displays the current working directory.
- ls: Lists directory contents.
- cd: Changes the working directory.
- cp: Copies files.
- rm: Removes files or directories.
- mkdir: Creates new directories.
- getuid: Retrieves the current user ID.
- make_token and steal_token: Create and impersonate tokens for identity manipulation.
- ps: Lists running processes.
- shell: Executes shell commands.
- sleep: Adjusts the sleep timer and jitter for evasion.
Xenon also includes several situational awareness commands, such as:
- sa_adcs_enum: Enumerates Certificate Authorities and templates in Active Directory.
- sa_arp: Lists the ARP table.
- sa_driversigs: Checks service image paths for AV/EDR vendor signatures.
- sa_get_password_policy: Retrieves password policies for a server or domain.
- sa_ipconfig: Displays IPv4 addresses, hostnames, and DNS servers.
The roadmap for Xenon includes addressing memory issues, implementing new commands for assembly execution and lateral movement, and integrating PowerShell support.
Despite its early stage, Xenon offers a promising platform for learning and experimentation with Windows internals and C programming.
