NxRansomware virus is back with malicious intentions

The illustration of NxRansomware ransom note

NxRansomware was first developed as an open-source ransomware project by G.B. Moralez. It was freely accessible on GitHub in 2016 for research purposes[1]. The developer explicitly prohibited people from exploiting this file-encrypting virus for malevolent purposes. However, researchers have spotted a malicious version of this malware spreading as a GoogleUpdate1.exe file on the cyberspace in December, 2017. 

The NxRansomware uses an AES and RSA encryption ciphers which are widely used by ransomware developers. Files strengthen by these algorithms are nearly impossible to break without a specific decryption key, and criminals demand to pay $300 in Bitcoins for it.

Questions about NxRansomware virus

The ransom note of NxRansomware is delivered in I'll Make You Cry 😀 😀 window and states the following:

What has happened To your Computer?

Your computer has been encrypted
It's better to pay ransom
Or we are going to make you feel sorry
Then nobody will help you out

According to the researcher, the virus is extremely dangerous and cause tremendous damage. NxRansomware is written in .Net Framework + C&C System, and is called as the next generation of ransomware. One of the objectives of this ransomware is to prove that it is possible to write a file-encrypting virus using the .Net Framework.

Apart from that, NxRansomware malware was initially created in order to understand ransomware operation principles. The researcher aimed to build a modern Command and Control (C&C) system and a safe communication channel between the virus and C&C server without using SSL certificates[2].

Fortunately, the researcher of this next generation crypto-malware has shared the open-source code with the developers of security software so they could prepare for the possible threats caused by the evolving ransomware projects. Thus, NxRansomware removal is not that complicated with the help of the antivirus tool.

NxRansomware virus attacks the most popular file types such as MS Office and OpenOffice documents, PDF and text files, various image, audio, video and other multimedia files, databases, archives, and more. It seems that G. B. Moralez managed to develop a hazardous cyber infection and now criminals take advantage of the scientific invention to obtain illegal profits.

However, you can remove NxRansomware with Reimage or another professional security software. It is still necessary to make sure that it is powerful enough to deal with ransomware attacks. Note that you should never pay the ransom since there are alternative ways how you can recover encrypted files.

Ransomware spreads as a fake Google Update file

Like most of the ransomware-type viruses, this one is distributed as an obfuscate Google Update file. Note that there numerous other deceptive software upgrades which hold the executables of the malware inside as well. Hackers might either sent them via spam emails or put in peer-to-peer file sharing networks. 

Ransomware can be placed as an attachment in email letter which urges to open it. Be aware that usually, criminals imitate famous companies and brands to trick gullible people into believing the legitimacy of the message. Likewise, once the attachment is opened, it drops the .exe file and infects the computer with ransomware.

Also, peer-to-peer networks are full of fake software updates which are malicious. Since crooks are able to create ransomware payloads which mimic the appearance of legitimate programs, most people get deluded and manually infiltrate file-encrypting viruses on the systems.

Likewise, you should pay close attention to the files you attempt to open or download. Never get software from unauthorized developers in highly suspicious pages. Additionally, in case of a dubious email from the well-known company — contact the firm yourself and validate the email.
