A new variant of Neptune RAT, targeting Windows users, is being spread through platforms like YouTube and Telegram. Cybersecurity researchers from CYFIRMA discovered the malware, which claims to be the “Most Advanced RAT” on platforms such as GitHub, Telegram, and YouTube. The malware attracts both newcomers to cybercrime and experienced hackers seeking a ready-made tool for their operations. Neptune RAT is designed to steal credentials, replace cryptocurrency wallet addresses, and even deploy ransomware to lock files.
The RAT is marketed for “educational and ethical purposes,” but its actual functions indicate malicious intent.
Written in Visual Basic .NET, Neptune RAT gives attackers complete control over an infected system. It can steal login details, monitor clipboard contents for cryptocurrency addresses, and replace them with attacker-controlled addresses. Additionally, it can encrypt files, drop ransom messages, and damage system components, including corrupting the Master Boot Record, making the system unusable.
Neptune RAT’s distribution method is unique in that it hides the executable file, making it harder to analyze. Some parts of the malware even use Arabic characters and emojis, adding complexity to reverse engineering. The malware generates PowerShell commands in its free version to download further components from file hosting services.
These components enhance its capability to perform credential theft, clipboard hijacking, ransomware deployment, and other dangerous activities while maintaining persistence on the victim’s system.
To protect against Neptune RAT, both individuals and organizations must be vigilant. It is crucial to download software only from trusted sources and ensure that systems, including security tools, are regularly updated. Additionally, using antivirus software that monitors file changes and network activity can provide an extra layer of defense. As the malware continues to evolve, experts recommend implementing strong endpoint defenses and threat detection measures to mitigate the risks of compromise.
