A new RAT is on the loose—and this one steals passwords, hijacks wallets, and won’t go down easy.

Cybersecurity experts are sounding the alarm over a new and dangerous version of Neptune RAT, a remote access tool targeting Windows devices that’s being marketed as “the most advanced RAT” across GitHub, Telegram, and YouTube. Despite being advertised for “educational purposes,” the malware’s capabilities say otherwise — and they’re raising serious concerns.

What exactly is Neptune RAT?

Built using Visual Basic .NET, Neptune RAT gives attackers full control over a compromised Windows system. It can steal login credentials, hijack cryptocurrency transactions, and even lock up files with ransomware. The free version is already circulating on shady corners of the internet, luring in both cybercrime newcomers and experienced threat actors looking for plug-and-play malware.

How it spreads and evades detection

Instead of releasing open-source code, the creator of Neptune RAT hides the executable file, making it harder to analyse. To dodge reverse-engineering, some of its code is disguised using Arabic characters and emojis. Once executed, the malware can auto-generate PowerShell commands that pull additional payloads from platforms like catbox.moe, a file hosting service.

Packed with dangerous features

Neptune RAT is more than just spyware. It’s modular, meaning attackers can pick and choose which features to deploy. Here’s what it’s capable of:

  • Credential theft from browsers and applications

  • Clipboard hijacking that swaps crypto wallet addresses

  • Ransomware features that encrypt files and demand payment

  • System sabotage, including possible damage to the Master Boot Record

  • Persistence tactics like Task Scheduler entries and registry edits

  • Virtual machine detection to avoid running in test environments

  • Live screen viewing, email and browser data theft, and more via additional DLL modules

How to protect yourself

The malware’s stealth and flexibility make it a real threat, especially to less tech-savvy users. Experts recommend the usual best practices: don’t install shady software, keep your system and antivirus up to date, and regularly back up important files. Also, make sure your antivirus tracks both system changes and suspicious network activity.

Why this malware is raising red flags

Experts have warned that Neptune RAT is especially concerning due to its ransomware abilities and real-time screen monitoring. He adds that its spread through legitimate platforms makes it easy to miss, even for seasoned defenders. As the RAT evolves, Swargam stresses the need for strong endpoint protection and active threat monitoring to stay ahead.

Stay sharp — when malware’s marketed as a “learning tool,” it’s probably not just for fun.
