Cado Security Labs have identified a Python Remote Access Tool (RAT) named Triton RAT. The open source RAT is available on GitHub and allows users to remotely access and control a system using Telegram. 

Technical Analysis

In the version of the Triton RAT we discovered, the Python script begins by retrieving the Telegram Bot token and chat ID from pastebin. 

Telegram token and chat ID encoded in Base64

Features of Triton RAT:

• Keylogging
• Remote commands
• Steal saved passwords
• Steal Roblox security cookies
• Change wallpaper
• Screen recording
• Webcam access
• Gather Wifi Information
• Download/upload file
• Execute shell commands
• Steal clipboard data
• Anti-Analysis
• Gather system information
• Data exfiltrated to Telegram Bot

The TritonRAT code contains many functions including the function “sendmessage” which iterates over password stores in AppData, Google, Chrome, User Data, Local, and Local State, decrypts them and saves the passwords in a text file. Additionally, the RAT searches for Roblox security cookies (.ROBLOSECURITY) in Opera, Chrome, Edge, Chromium, Firefox and Brave, if found the cookies are stored in a text file and exfiltrated. A Roblox security cookie is a browser cookie that stores the users’ session and can be used to gain access to the Roblox account bypassing 2FA.

Secondary payload retrieved from DropBox 

The Python script also contains code to create a VBScript and a BAT script which are executed with Powershell. The VBScript “updateagent.vbs” disables Windows Defender, creates backups and scheduled tasks for persistence and monitors specified processes. The BAT script “check.bat” retrieves a binary named “ProtonDrive.exe” from DropBox, stores it in a hidden folder and executes it with admin privileges. ProtonDrive is a pyinstaller compiled version of TritonRAT. Presumably the binary is retrieved to set up persistence. Once retrieved, ProtonDrive is stored in a created folder structure “C:\Users\user\AppData\Local\Programs\Proton\Drive”. Three scheduled tasks are created to start on logon of any user.

For anti analysis, Triton RAT contains a function that checks for “blacklisted” processes which include popular tools such as xdbg, ollydbg, FakeNet, and antivirus products. Additionally, the same Git user offers a file resizer as defense evasion as some AV will not check a file over a certain amount of MB. 

All the exfiltrated data is sent to Telegram via a Telegram bot, where the user can send commands to the affected machine. At the time of analysis, the Telegram channel/bot had 4549 messages, although it is unknown if these are indicative of the amount of infections.
