Remove Nile Ransomware (.nile Decryption)

Nile ransomware is a hazardous computer threat that is targeting majority of user’s files including documents, spreadsheets, videos, images, archives, databases, drawings, presentations, and similar data. It was detected that Nile ransomware have the same pattern as the entire malware from STOP/DJVU group. Earlier variants as Kuus, Erif, Kook, and this latest threat are using a sophisticated encryption technique to lock user’s files and deny them access. To make the data accessible once more, victim must pay the amount as indicated in the ransom note.

Nile ransomware reach the target user through several methods but the most winning of all is the use of spam email campaign. On this scenario, attackers are sending Nile ransomware as attachment to message that is purporting to be from legitimate organization. The virus is cleverly in disguise of a document file and for that; recipient would never be suspicious when opening it. The context of the message usually revolves about relevant inquiries, which points to the attach file for full details.

If recipient opens the attachment, Nile ransomware initiates the attack and begin to download malicious codes on various locations especially on Windows system folder. It also creates a registry entry to run the malicious code on each Windows start-up. Next, Nile ransomware will scout the local drive for important data and encrypt them with complex algorithm. While encrypting, the virus also appends an identifier to infected files by adding a .nile file extension. On that note, a simple abc.doc will transform into abc.doc.nile after the encryption process. Lastly, Nile ransomware generates a ransom note on the same exact location as encrypted files containing brief description and ways to recover all .nile encrypted files. Attacker demands $980 in exchange for the Nile decryption tool and private key that are both needed to recover encrypted files.

Unfortunately, designated payment channel is suspicious and there is no way for victims to request for a refund just in case the deal did not materialize. Makers of Nile ransomware can flee away without a trace after receiving the ransom payment. So, there is no guarantee that victims are going to receive the Nile decryption tool after transmitting the money.
