.Ntuseg file extension ransomware virus. Ntuseg decryption tool.

A ransomware called Ntuseg file virus is another development of scammers.

Upon encryption, all affected documents, photos and music will then be appended with the .ntuseg extension (e.g., ‘photo.jpg is renamed to ‘photo.jpg.ntuseg’). Ransomware leaves a ransom demanding message called ‘_readme.txt’ with instructions for extortion and ransom payment, threatening destruction of files if payment is not made. The ransomnote directs victims to make payment online in Bitcoins.

How to decrypt .ntuseg files

As mentioned earlier, the ransom payment is the only way to unlock .ntuseg files, unfortunately. After the victim transfers the specified amount of money (usually $980 in Bitcoins) to the cyber frauds, they provide a private key to decrypt the affected data.

Never pay the ransom! However, the victim who will pay the money to attackers cannot be completely sure of obtaining a private key, because he is dealing with unscrupulous and dishonest people who are ready to commit any immoral actions, including hiding after receiving the ransom payment from the user, and not providing a decryption utility (key) to recover access to blocked photos, documents and music.

The Ntuseg file virus is not the only one of its kind, for some of them, there are already methods to decrypt locked files that were created by security researchers. This gives hope that the Ntuseg decryption tool can be designed for this ransomware as well. However, since each case of coding is original, victim should seek help and provide an identifier that will give the opportunity to get the private key and decryption utility.

Ntuseg decryption tool

With some variants of Ntuseg file virus, it is possible to decrypt encrypted files using free tools listed below.

Michael Gillespie (@) released the Ntuseg decryption tool named STOPDecrypter. It can decrypt .Ntuseg files if they were locked by one of the known OFFLINE KEY’s retrieved by Michael Gillespie. Please check the twitter post for more info.

STOPDecrypter is a program that can be used for Ntuseg files decryption. One of the biggest advantages of using STOPDecrypter is that is free and easy to use.
