The Nhtnwcuf Ransomware is a threat infection that pretends to encrypt the victim's files, but, instead, deletes them and makes them unrecoverable completely. Considering that such a high percentage of ransomware creators never follow up after the victim pays the ransom, there is not much difference in practice between a the Nhtnwcuf Ransomware infection and an attack involving a better-known ransomware family. However, the attack method of the Nhtnwcuf Ransomware goes to reinforce the advice from PC security researchers to never pay the ransom demanded by ransomware Trojans.

Nhtnwcuf Ransomware – A Weird Name for a Harmful Ransomware

Most ransomware Trojans encrypt the victims' file using a strong encryption method such as the RSA, the AES and the XOR. This makes the affected files completely inaccessible until the victim pays a ransom to receive a decryption key. In fact, victims will rarely receive the means to decrypt their files. The Nhtnwcuf Ransomware simply illustrates this fact, not bothering to even encrypt the victim's files but instead just overwriting the data in the affected files with random characters. This means that the files that have been 'encrypted' by the Nhtnwcuf Ransomware become impossible to recover since there is no encryption going on. Computer users should always avoid paying the ransom in these attacks, but this is especially true when it comes to the Nhtnwcuf Ransomware.

How the Nhtnwcuf Ransomware Attack Works

After the Nhtnwcuf Ransomware 'encrypts' the victim's files, computer users will find a text file named either '!_RECOVERY_HELP_!.txt' or 'HELP_ME_PLEASE.txt' on the infected computer's desktop. This file contains the following text:

'After purchasing a software package with the unique decryption key you'll be able to:
* Decrypt all your files
* Work with your documents
* View your photos and other media content
Continue habitual and comfortable work at your computer
>>> Follow 3 Steps in Exact Order <<< 1. In case if you don't already have, Register/Create a BitCoin Wallet. 2. Send 1.00 BTC ( One Bitcoin ) to the following BitCoin Address: ---------------------------------- [34 RANDOM CHARACTERS] ---------------------------------- 3. Send confirmation to the following E-mail address: -------------------------'

There is no truth to any of the claims in this ransom note. PC security researchers have already received numerous reports of the Nhtnwcuf Ransomware attacks, which are being used to target servers and other high-profile targets. The Nhtnwcuf Ransomware represents a severe threat to data since it destroys data rather than encrypting it. The files that have been 'encrypted' by the Nhtnwcuf Ransomware will have the extension '.mkf,' '.ije,' or '.nwy,' a characteristic used by real ransomware Trojans to identify the infected files.

Dealing with the Nhtnwcuf Ransomware

PC security researchers strongly advise computer users to avoid paying the ransom involved in any ransomware Trojan attack. This is especially true when it comes to dealing with the Nhtnwcuf Ransomware since there is no encryption involved or hope of recovery. The Nhtnwcuf Ransomware is simply taking advantage of the high number of ransomware Trojans that have been active since 2015, counting on the fact that many unprotected computer users and server administrators may be willing to pay the ransom. Malware researchers strongly advise computer users to have backups in place for all files. Having backups allows computer users to recover their files easily after removing the Nhtnwcuf Ransomware from the infected computer and deleting the affected files, which become completely useless effectively.

A reliable security program that is fully up-to-date should be able to delete the Nhtnwcuf Ransomware and intercept it before it causes too much damage. However, threats like the Nhtnwcuf Ransomware may be distributed through social engineering techniques, often using corrupted email attachments, or by injecting it into servers by taking advantage of weak passwords and security measures directly. Taking steps to ensure that adequate protections are in place and all files are backed up regularly on the cloud, or an external memory device is the best protection against the Nhtnwcuf Ransomware and similar threats.
