Nog4yH4n virus Removal Guide
What is Nog4yH4n ransomware?
Nog4yH4n – ransomware which is considered to be yet another Hidden Tear project's version
Nog4yH4n ransomware - a file locking cyber threat which uses the .locked appendix to encrypt valuable documents on the infected PC.
Nog4yH4n is a file-encrypting virus which has close similarities with Hidden Tear ransomware. Once installed, this cyber threat creates dubious registry entries in the Windows Registry which allows it to perform harmful activities. Moreover, Nog4yH4n virus, also known as Nog4yH4n Project ransomware, uses unique encryption algorithms to lock files and ads the .locked extension to each blocked document. After that, the ransomware displays a ransom-demanding message named “HACKED_NOG4YH4N.txt” which urges for Bitcoin and even food in exchange for the file decryption tool.
|Ransom||Bitcoin or food is urged|
|Also related to||Hidden Tear|
|Removal||Install ReimageIntego and detect the virus|
Nog4yH4n ransomware price-demanding message looks like this:
This computer has been hacked
Your personal files have been ecrypted. Send me BTC or food to get decryption passcode.
After that, you'll be able to see your beloved files again.
With love… Nog4yH4n Project')
Nog4yH4n ransomware uses unique encryption algorithms that are based on AES or RSA to lock up important files on the victim's computer. Each time this virus affects a different computer, the code differs too. This is the main reason, why even highly-experienced IT professionals find the decryption key almost impossible to discover.
Moreover, ransomware such as Nog4yH4n demands Bitcoin or another type of cryptocurrency because such currency transfers keep the entire process safe and untrackable. This is a valuable reason not to pay the demanded ransom. If you get scammed by the cybercriminals, there will be no chance of getting lost money back.
We advise performing the Nog4yH4n removal by using reliable anti-malware tools. You can try running a program such as ReimageIntego. However, note that you need to take care of the virus first before you start thinking about file decryption. Otherwise, the data recovery process will give no results as the cyber threat will still be active inside the computer system.
You need to remove Nog4yH4n virus as soon as you spot files encrypted with the .locked appendix. There is no need for hesitation as the longer you wait, the more difficult the elimination process will be. However, manual removal is not possible for this case as the virus might leave numerous dubious components behind which might be undetected by the human eye.
Nog4yH4n ransomware - a virus which enters the computer system via phishing email messages.
Phishing messages often spread ransomware
According to malware researchers, spam emails are the most common ransomware distribution source. The hazardous payload is clipped as an attachment to the dubious email and waits for its turn to launch the dangerous virus. If you are not expecting anything important at the moment and have received a strange-looking email from an unknown sender, better eliminate such message and do not open any attachments clipped to it if there are some.
Moreover, you can take some precautionary measures by protecting your personal files. What you need to do is purchase a USB drive and copy all important information to this external device. If you do so, the ransomware virus will not be able to reach files that are stored on the USB if it is unplugged from your computer.

How to prevent from getting ransomware
Access your website securely from any location
When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.
If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.
Recover files after data-affecting malware attacks
While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.
Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
