We retrieve data that has been encrypted by the majority of ransomware file extensions on any type of storage device
Decrypt Ryuk ransomware files
By utilising our distinctive methods, the restoration of Ryuk encrypted files has become a feasible prospect.
In recent years, Ryuk ransomware attacks have emerged as a primary and highly destructive form of cyber attack. An unparalleled rise has been observed in the number of businesses that have fallen prey to such attacks resulting in complete encryption of their data.
Many of these attacks are specific and targeted at the victim company, such attacks have huge destructive potential. Not only is the group in no hurry to start the process of encrypting the data, without first having reached online backups and as many devices on the network as possible, this process can last for months, and by the time the Ryuk ransomware is executed it can encrypt the vast majority of data or even 100% of files.
When faced with such a catastrophic situation, there is often little that can be done, particularly if backups have been compromised or are not current. It is staggering to note the quantity of companies that have been forced to cease operations after having their data encrypted.
In numerous instances, despite paying the ransom, the Ryuk criminals do not provide the decryption key, leaving the victim without any recourse.

- Consider the cost: Decryption services can be expensive, so it’s important to compare prices between different companies. However, don’t make cost your only deciding factor as the cheapest option may not always be the best.
- Look for experience: Choose a company that has experience in decrypting data similar to yours. This will increase the likelihood of a successful decryption.
- Ask about their data security measures: Make sure the company has strong data security measures in place to protect your sensitive data.
By following these tips, you can choose Digital Recovery as the company to decrypt your data and recover your important files.
How much does the process to decrypt Ryuk ransomware cost?
The cost to decrypt Ryuk ransomware can vary depending on the severity of the attack and the complexity of the decryption process. The cost may also depend on the version of Ryuk ransomware and the specific files that need to be decrypted. This can only be determined once the extent of damage caused by the ransomware has been analysed and the possibility of decryption has been evaluated.
It’s important to note that there is no guarantee that decryption will be successful, and some files may be permanently lost or corrupted. Therefore, it’s important to find a company that doesn’t ask the full amount of the project upfront. It’s best to consult with a reputable data recovery company to get an accurate estimate of the cost for your particular situation.
Is negotiating with Ryuk hackers a good option?
No, negotiating with hackers is generally not a good option. When you negotiate with Ryuk hackers, you are essentially agreeing to their demands and supporting their criminal activities. This can encourage them to continue their illegal activities and target other victims.
Moreover, there is no guarantee that the hacker will actually release your data or decrypt your files, even if you pay the ransom. In some cases, Ryuk may take the money and still refuse to provide the decryption key or release the data.
Additionally, paying the ransom can also lead to other negative consequences. It can put your personal information and sensitive data at risk, as the hacker may have gained access to your system and stolen additional information. It can also lead to legal and ethical issues, as paying the ransom is considered to be supporting criminal activities.
Therefore, it is generally recommended to not negotiate or pay the ransom to hackers. Instead, victims should report the attack to law enforcement and seek the assistance of a reputable data recovery to retrieve their data and strengthen their security measures to prevent future attacks.

What you need to know
How to prevent a Ryuk ransomware attack?
To prevent Ryuk 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.
What is the most common means of access used by Ryuk hackers to break into environments?
The most common means of access used by Ryuk hackers to break into environments is through exploiting vulnerabilities in software, hardware, or human behaviour. This can include:
- Phishing attacks: Hackers use fraudulent emails, social media messages, or phone calls to trick individuals into revealing their login credentials or other sensitive information.
- Password attacks: Hackers use various techniques, such as brute force or dictionary attacks, to guess or crack passwords.
- Malware: Hackers use malicious software, such as viruses, worms, or Trojans, to infect computers or other devices and gain access to sensitive data.
- Software vulnerabilities: Hackers use known vulnerabilities in software, such as operating systems, web servers, or applications, to gain unauthorised access to a system.
- Misconfigured or unpatched systems: Hackers exploit weaknesses in system configurations or outdated software that has not been patched or updated to gain access.
- Social engineering: Hackers use social engineering techniques, such as pretexting or baiting, to manipulate individuals into divulging sensitive information or granting access to secure systems.
To reduce the risk of a successful attack, it’s important to implement security best practises, such as strong passwords, two-factor authentication, regular software updates and patches, employee security awareness training, and the use of security tools like firewalls, intrusion detection systems, and antivirus software.
Is there any behaviour of my server that I can analyse to know if I am being attacked by Ryuk Ransomware?
Yes, there are several behaviours of your server that you can analyse to determine if you are being attacked by Ryuk ransomware:
- High resource usage: If your server’s processing, memory, and disk usage are significantly higher than usual, it could indicate that ransomware is actively encrypting files or exfiltrating data.
- Changes in file extensions: Ryuk Ransomware often renames files with a new extension, such as .encrypted or .locked. If you notice such changes, it may be a sign that your server has been attacked.
- Unusual network traffic: Ryuk Ransomware needs to communicate with its command and control (C&C) server to receive instructions and report back on its progress. Analysing network traffic for unusual connections or data transfers can help you identify potential ransomware activity.
- Suspicious login attempts: Ryuk Ransomware attackers often gain access to a server through phishing emails or brute force attacks on weak passwords. Monitoring your server’s login attempts and blocking suspicious activity can help prevent ransomware attacks.
- Unusual system modifications: Ryuk Ransomware may make modifications to your server’s operating system or file system to carry out its attack. Keep an eye out for any changes to system files, registry entries, or other critical components.
By analysing these behaviours, you can potentially detect and prevent a Ryuk ransomware attack on your server. It’s important to stay vigilant and implement security measures to protect against ransomware and other cyber threats.
What happens if I don't pay the Ryuk ransom?
If you are the victim of a Ryuk ransomware attack and you do not pay the ransom demanded by the hackers, several things could happen:
- Your data remains encrypted: If your files are encrypted by the Ryuk 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.
- The attackers may delete your files: Some Ryuk 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.
- 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 Ryuk ransomware attacks, such as implementing strong cybersecurity measures, regularly backing up your data, and educating yourself and your employees about potential attack vectors.
