What is NURRI Ransomware
NURRI Ransomware is part of the Phobos ransomware family. Like other representatives of Phobos ransomware, this virus encrypts files aside from locking a system and demands payment from affected users in exchange for a decryption key to unlock the encrypted files. The ransomware appends the .NURRI extension to filenames and provides two ransom notes (info.hta and info.txt). The ransom note states that all files have been encrypted due to a security problem with the user’s PC. The virus encrypts files using a strong encryption algorithm and a key (‘offline key’ or ‘online key’). It tries to encrypt as many files as possible, for this it only encrypts the first 154kb of the contents of each file and thus significantly speeds up the encryption process. NURRI has the ability to encrypt files on all drives connected to the computer: internal hard drives, flash USB disks, network storage, and so on. Below are the samples of ransom notes presented to the victim:

However, there are some file types that can be repaired. Victims may have to recover their data by recreating the data from scratch, restoring from backups, or paying the ransom. It is important to note that paying the ransom does not guarantee that the files will be decrypted, and it may encourage cybercriminals to continue their illegal activities.
How Nurri Ransomware infected your computer
NURRI ransomware is often spread through phishing emails that contain malicious attachments or through drive-by downloading. Drive-by downloading occurs when a user unknowingly visits an infected website and then malware is downloaded and installed without the user’s knowledge. Additionally, newer methods of ransomware infection have been observed. For example, vulnerable Web servers have been exploited as an entry point to gain access to an organization’s network.
