What is Defi Ransomware
Defi Ransomware represents a significant threat in the realm of cybersecurity. This particular ransomware, part of the Makop family, operates by encrypting the victim’s files and appending a distinctive extension to their names. For instance, original filenames are modified by adding a unique ID, the attackers’ email address, and a .defi[random] extension, making the files inaccessible. On our test system, a file named photo.jpg was transformed into photo.jpg.[random-ID].[wewillrestoreyou@cyberfear.com].defi1328. Post encryption, the ransomware drops a ransom note in a text file named +README-WARNING+.txt, which typically appears on the desktop. The cybercriminals behind Defi ransomware request a ransom payment for the decryption key, promising to provide the decryption tool and warning against using third-party software, which they claim could result in permanent data loss.

:::BEWARE:::
DON'T try to change encrypted files by yourself!
If you will try to use any third party software for restoring your data or antivirus solutions - please make a backup for all encrypted files!
Any changes in encrypted files may entail damage of the private key and, as result, the loss all data.Paying the ransom does not guarantee data recovery, as many victims report not receiving decryption keys even after payment. Currently, no free decryption tools are available for Defi Ransomware, largely due to its use of robust encryption algorithms. These encryption methods are so sophisticated that without the proper decryption key, recovering your files is nearly impossible. The best course of action to combat files with the .defi[random] extension is to restore them from a previously created backup. If a backup is unavailable, you may attempt to use data recovery tools, such as Recuva, which can sometimes recover un-encrypted versions of the files. However, this method is not foolproof. It’s crucial to maintain up-to-date backups and cybersecurity measures to prevent future ransomware infections and avoid being placed in a precarious situation where data is at the mercy of cybercriminals.
How Defi Ransomware infects computers
Defi Ransomware infiltrates computers primarily through sophisticated phishing campaigns, malicious email attachments, and deceptive download links. Cybercriminals often disguise the malware as legitimate files or bundle it with seemingly benign software, tricking users into executing the malicious payload. Once activated, Defi Ransomware exploits system vulnerabilities and security gaps to gain access and initiate the encryption process. Additionally, it can spread through compromised websites, drive-by downloads, and malicious advertisements, further increasing its reach. The ransomware may also utilize trojans and backdoors to stealthily infiltrate systems, making it essential for users to maintain robust cybersecurity practices and regularly update their software to mitigate the risk of infection.

How to protect computer from viruses, like Defi Ransomware, in future
1. Get special anti-ransomware software
Use ZoneAlarm Anti-Ransomware
Famous antivirus brand ZoneAlarm by Check Point released a comprehensive tool, that will help you with active anti-ransomware protection, as an additional shield to your current protection. The tool provides Zero-Day protection against ransomware and allows you to recover files. ZoneAlarm Anti-Ransomware is compatible with all other antiviruses, firewalls, and security software except ZoneAlarm Extreme (already shipped with ZoneAlarm Anti-Ransomware) or Check Point Endpoint products. The killer features of this application are: automatic file recovery, overwrite protection that instantly and automatically recovers any encrypted files, file protection that detects and blocks even unknown encryptors.
2. Back up your files
As an additional way to save your files, we recommend online backup. Local storage, such as hard drives, SSDs, flash drives, or remote network storage can be instantly infected by the virus once plugged in or connected to. Defi Ransomware uses some techniques to exploit this. One of the best services and programs for easy automatic online backup is iDrive. It has the most profitable terms and a simple interface. You can read more about iDrive cloud backup and storage here.
3. Do not open spam e-mails and protect your mailbox
Malicious attachments to spam or phishing e-mails are the most popular method of ransomware distribution. Using spam filters and creating anti-spam rules is good practice. One of the world leaders in anti-spam protection is MailWasher Pro. It works with various desktop applications and provides a very high level of anti-spam protection.
