The Neptune RAT, also known as the "Most Advanced RAT" (or remote access trojan), is a new malware strain that fraudsters are using to infect susceptible Windows PCs in a recent campaign. The attackers in this cyberattack are trying to take credentials, cryptocurrency and keep users hostage. 

A report by Cybernews reveals that Neptune RAT is a powerful and dangerous type of malware that can take control of Windows devices, monitor the user’s activities, and perform several other harmful tasks — all while staying hidden from even the best antivirus programs. According to cybersecurity company CYFIRMA, this malware is currently being shared on platforms like GitHub, Telegram, and YouTube. Like many other malware types, Neptune RAT follows a “malware-as-a-service” model, meaning hackers can pay a monthly fee to use it for their own attacks. 

CYFIRMA described Neptune RAT as a powerful remote access tool with many harmful features. One of its most worrying abilities is a "crypto clipper," which watches for cryptocurrency transactions and secretly swaps the wallet address with one owned by hackers. This means the victim's money is sent to the attackers without them knowing. Neptune RAT doesn't just target digital files—it also has a built-in password-stealing feature. This allows it to grab login details from more than 270 different applications, including popular web browsers like Chrome. With this stolen information, attackers can break into social media accounts, access financial services, and carry out more attacks.

But that's not all. This malware can do even more damage. It comes with a ransomware feature that locks your files and demands money to unlock them. It can also turn off Windows Defender and other antivirus programs, making it harder for your computer to spot or stop the infection. Neptune RAT also has a screen monitoring feature, which lets attackers watch what the user is doing on their computer in real time. This can lead to spying, blackmail, or stealing personal information. If the attackers feel they’ve gotten what they need, Neptune RAT has a built-in option to erase all data on the infected system completely, leaving no evidence behind. Right now, Neptune RAT is being shared on platforms like GitHub, Telegram, and YouTube. So, it's a good idea for users to avoid these websites for the time being or be very careful when downloading files or clicking on links from them.

It's also smart to invest in a good identity theft protection plan. These plans can help recover any money lost in an attack and often include insurance, which can be helpful if you need to replace your computer after being affected.
