Recovery of files affected by Nefilim Ransomware

To prevent Nefilim ransomware attacks, it is important to have a comprehensive cybersecurity framework in place. However, there are some additional key points that you should keep in mind:

• Organisation: Keep documentation of your IT systems and maintain an inventory of all networks and computers. Establish clear rules for new employees on the installation and use of software programmes on company computers.
• Strong Passwords: Use strong passwords with at least 8 characters, including special characters, and avoid using the same password for multiple accounts.
• Security Solutions: Install a reliable antivirus software and ensure that all software programmes, especially the operating system, are kept up to date. In addition to antivirus software, also consider installing a firewall and endpoint protection to provide comprehensive security.
• Beware of Suspicious Emails: Email is a common method used by hackers to infiltrate systems. Train employees to recognise and avoid downloading attachments from unknown senders.
• Efficient Backup Policies: Backups are crucial in the event of a ransomware attack, but many companies fail to create an effective backup plan. The recommended backup structure is 3x2x1, which means having 3 backups, 2 online and 1 offline, and regularly updating them.
• Beware of Unofficial Programmes: Avoid downloading unofficial, free versions of software programmes like Windows or Office, as they may be infected with malware. Invest in official software programmes, as they are a good long-term investment and are also more secure.

Hackers use a variety of methods to infiltrate a victim’s system, including downloading infected files, malicious links, RDP attacks, phishing, and spam emails. Their goal is to gain access to the system undetected, and to achieve this, the Nefilim ransomware is often disguised to evade detection by security systems.

When it comes to tactics that rely on user action, hackers employ phishing techniques to trick unsuspecting victims into downloading Nefilim ransomware onto their systems without realising it.

Suspicious behaviour such as high usage of processing, memory, and disk access should be thoroughly investigated to determine if a ransomware attack is in progress. Nefilim Ransomware typically exploits a machine’s own resources to carry out the encryption process and exfiltration of data. Detecting the attack can also be done by observing changes in file extensions, although this method is more complicated as the encryption process may have already started.

If you are the victim of a Nefilim ransomware attack and you do not pay the ransom demanded by the hackers, several things could happen:

1. Your data remains encrypted: If your files are encrypted by the Nefilim ransomware, they will remain inaccessible until the encryption is removed. Without the decryption key provided by the attackers, you may be unable to access your data.
2. The attackers may delete your files: Some Nefilim ransomware attackers may threaten to delete your files if you do not pay the ransom within a certain timeframe. If you refuse to pay and the attackers follow through on their threat, you may lose all of your data.
3. The attackers may leak your data: In some cases, the attackers may use a double-extortion tactic, in which they not only encrypt your files but also steal them and threaten to release them publicly if you do not pay the ransom. If you refuse to pay and the attackers follow through on their threat, your data may be released to the public or sold on the dark web.

Paying the ransom is not recommended, as it incentivizes attackers to continue their criminal activities and there is no guarantee that they will provide you with the decryption key or honor their promises. Instead, it’s important to take steps to prevent Nefilim ransomware attacks, such as implementing strong cybersecurity measures, regularly backing up your data, and educating yourself and your employees about potential attack vectors.
