Threat researchers at Netskope have identified a new Remote Access Trojan (RAT) named “Nursultan Client,” disguised as a legitimate application for Minecraft enthusiasts. This malware, developed in Python, uses the Telegram Bot API for command-and-control operations, enabling data exfiltration and persistent access to compromised systems. It was first detected as a 68.5 MB executable compiled with PyInstaller, which is often used for legitimate software but can also bundle malicious scripts. Upon execution, the RAT misleads users with a fake installation progress bar. Its core functionalities operate across Windows, Linux, and macOS platforms, targeting the gaming community through social engineering tactics. The malware contains hardcoded Telegram credentials, allowing attackers to issue commands to infected machines while obscuring their communications. The RAT can execute various commands, including stealing Discord authentication tokens and conducting system reconnaissance. It also offers surveillance capabilities, such as capturing screenshots and webcam images, and has adware functionalities that can open URLs or display pop-up messages. The operation appears to be aimed at lower-tier threat actors, lacking advanced anti-analysis techniques and sophisticated tradecraft. Organizations are advised to monitor encrypted traffic and educate users on software authenticity to mitigate risks.
