Nord is a DJVU family of ransomware-type infections1. This infection encrypts your private files (video, photos, documents). The encrypted files can be tracked by specific “.nord” extension. So, you can’t open them at all.
In this article I will try to help you remove Nord ransomware without any payment. Also I will assist you in decoding your encrypted files.
What is “Nord”?
Nord can be correctly identify as a ransomware infection.
Ransomware is a kind of virus that encrypted your documents and then forces you to pay for them. DJVU (aka STOP) ransomware family was first revealed and analyzed by virus analyst Michael Gillespie2.Nord is basically similar to other representatives of the same family: Boop, Vari, Oonn. Nord encrypted all common file types. Hence, you cannot open the own documents or photos. Nord adds its particular “.nord” extension into all files. For instance, the file “video.avi”, will be amended into “video.avi.nord”. As soon as the encryption is successfully accomplished, Nord generates a specific file “_readme.txt” and drop it into all folders that contain the modified files.
Here is a summary for the Nord ransomware:

This text asking payment is for get files back via decryption key:
The scary alert demanding from users to pay the ransom to decrypt the compromised data contains these frustrating warnings
The cryptography algorithm used by Nord is AES-256. So, if your documents got encrypted with a specific decryption key, which is totally and there are no other copies. The sad reality is that it is impossible to recover the information without the unique key available.
In case if Nord worked in online mode, it is impossible for you to gain access to the AES-256 key. It is stored on a remote server owned by the frauds who distibute the Nord infection.
For receiving decryption key the payment should be $980. To obtain the payment details, the victims are encouraged by the message to contact the frauds by email (helpmanager@mail.ch), or via Telegram.
Do not pay for Nord!
Please, try to use the available backups, or Decrypter tool
_readme.txt file also indicates that the computer owners must get in touch with the Nord representatives during 72 hours starting from the moment of files where encrypted. On the condition of getting in touch within 72 hours, users will be granted a 50% rebate. Thus the ransom amount will be minimized down to $490). Yet, stay away from paying the ransom!
I definitely recommend that you do not contact these frauds and do not pay. The one of the most real working solution to recover the lost data – just using the available backups, or use Decrypter tool.
The peculiarity of all such viruses apply a similar set of actions for generating the unique decryption key to recover the ciphered data.
Thus, unless the ransomware is still under the stage of development or possesses with some hard-to-track flaws, manually recovering the ciphered data is a thing you can’t perform. The only solution to prevent the loss of your valuable data is to regularly make backups of your crucial files.
Note that even if you do maintain such backups regularly, they ought to be put into a specific location without loitering, not being connected to your main workstation.
For instance, the backup may be kept on the USB flash drive or some alternative external hard drive storage. Optionally, you may refer to the help of online (cloud) information storage.
Needless to mention, when you maintain your backup data on your common device, it may be similarly ciphered as well as other data.
For this reason, locating the backup on your main device is surely not a good idea.
How I was infected?
Nord has a various methods to built into your system. But it doesn’t really matter what concrete method was used in your case.
Nord ransomware attack following a successful phishing attempt.
- hidden installation along with other apps, especially the utilities that work as freeware or shareware;
- dubious link in spam emails leading to the Nord installer
- online free hosting resources;
- using illegal peer-to-peer (P2P) resources for downloading pirated software.
There were cases when the Nord virus was disguised as some legitimate tool, for example, in the messages demanding to initiate some unwanted software or browser updates. This is typically the way how some online frauds aim to force you into installing the Nord ransomware manually, by actually making you directly participate in this process.
Surely, the bogus update alert will not indicate that you are going to actually inject the Nord ransomware. This installation will be concealed under some alert mentioning that allegedly you should update Adobe Flash Player or some other dubious program whatsoever.
Of course, the cracked apps represent the damage too. Using P2P is both illegal and may result in the injection of serious malware, including the Nord ransomware.
To sum up, what can you do to avoid the injection of the Nord ransomware into your device? Even though there is no 100% guarantee to prevent your PC from getting damaged, there are certain tips I want to give you to prevent the Nord penetration. You must be cautious while installing free software today.

How to decrypt .nord files?

Try removing .nord extension on a few BIG files and opening them. Either the Nord ransomware read and did not encrypt the file, or it bugged and did not add the filemarker. If your files are very large (2GB+), the latter is most likely. Please, let me know in comments if that will work for you.
The newest extensions released around the end of August 2019 after the criminals made changes. This includes Nile, Kook, Erif, etc.
