Recover Onyx ransomware files

Have your files been locked by Onyx ransomware? Act fast to safely restore your data.

Ransomware attacks are among today’s greatest digital threats, showing constant growth and affecting organizations of various sizes and sectors. Recent surveys indicate that over 70% of these attacks lead to full file encryption, with around 56% of victims paying the ransom demanded. However, specialized solutions exist that allow data recovery without directly negotiating with hackers. Developed to cause significant damage, Onyx ransomware is advanced malware specifically targeting critical file encryption, making them inaccessible to both home users and businesses. Its recent prominence stems from its proven ability to disrupt fundamental operations in essential sectors such as healthcare, industry, education, and finance.

Contrary to common viruses, Onyx ransomware is often operated by sophisticated criminal organizations using robust algorithms like AES-256 and RSA to encrypt critical files, maintaining control of the necessary decryption key.
In addition, the practice known as double extortion is common, wherein besides encrypting files, hackers steal copies of sensitive data to threaten victims with public exposure.

Ransomware attacks have grown rapidly, with an estimated increase of around 5% in just the last year and average ransom demands reaching millions of dollars. Many affected companies end up paying the ransom due to ignorance of effective alternatives, directly contributing to the continuation of these criminal activities.

We provide specialized solutions for the secure recovery of ransomware-encrypted files.

Answers from our experts

How does the Onyx ransomware attack work?

Onyx ransomware executes its attack through a clear and defined sequence of steps:

  • Silent infiltration: The first stage of the attack involves phishing techniques, where criminals send emails with malicious links or attachments to victims. Another common strategy includes exploiting technical vulnerabilities in outdated systems, such as flaws in old programs or insecure remote access (RDP).
  • Backup mapping and neutralization: After the initial entry, the ransomware conducts an internal network reconnaissance, identifying strategic files and particularly connected or online backups. The aim is also to compromise these backups, eliminating quick recovery options.
  • Mass encryption of files: Right after identifying strategic data, ransomware rapidly encrypts the information. Typically, essential files like databases, ERP systems, virtual machines, and RAID systems are affected, making information access impossible.
  • Financial extortion: Upon completion of file encryption, criminals typically leave a ransom note demanding payment. Generally, instructions guide victims to communicate through secure channels or the dark web, specifying cryptocurrency payments to hinder financial tracking.

How much does it cost to decrypt Onyx ransomware?

The exact cost to decrypt files affected by Onyx ransomware directly depends on the extent and technical complexity of the attack. The total cost of the process is directly linked to the amount of affected information, the category of impacted systems (servers, virtual machines, storages, or databases), and the availability of usable backups. To quickly start the process and get an accurate quote, we recommend requesting an initial diagnosis with our specialized team. Talk to our experts.

How long does the data recovery take?

The timeline for data recovery varies according to the specific circumstances of each attack. Generally, the process can range from a few days to several weeks, mainly depending on the volume of affected files, the extent of the impacted infrastructure, the complexity of the ransomware involved, and the condition of available backups. After receiving your contact, we perform an initial diagnosis within 24 business hours, and then our team will inform you of a clear and personalized estimate of the timeframe required to complete your data recovery.

Is there any guarantee for data recovery?

Considering the technical complexity of ransomware attacks, no responsible company can guarantee in advance the complete recovery of files. Each incident presents unique technical aspects, such as different cryptographic algorithms and specific methods employed by criminals. Even so, Digital Recovery employs innovative and exclusive solutions, especially the proprietary TRACER technology, which ensures a very high success rate in recovering data affected by ransomware.

How to prevent a Onyx ransomware attack?

Preventing a Onyx ransomware attack requires a comprehensive cybersecurity framework, but that’s not all, let’s list some important points that you need to pay attention to.

  1. Keep software and operating systems up to date: Regularly update software and operating systems with the latest security patches to protect against known vulnerabilities.
  2. Use strong passwords and two-factor authentication: Use strong, unique passwords for all accounts and enable two-factor authentication to add an extra layer of security.
  3. Educate employees: Train employees on how to recognize phishing emails and other social engineering tactics used by cybercriminals.
  4. Back up data regularly: Make sure to regularly back up important data to a secure, offsite location.
  5. Use antivirus and antimalware software: Use reputable antivirus and antimalware software and keep it up to date.
  6. Limit user access: Restrict user access to only what is necessary to perform their job functions and regularly review and remove unnecessary access.
  7. Monitor network traffic: Regularly monitor network traffic to detect unusual activity or traffic patterns.
  8. Have an incident response plan: Develop and regularly test an incident response plan to respond quickly and effectively to a ransomware attack.

By following these best practices, organizations can help reduce their risk of falling victim to a Onyx ransomware attack.

There are several strategies employed by Onyx criminals, the main ones are: downloads of infected files, malicious links, attacks via RDP, Phishing, spam email campaigns, and more. 

All of them have the same intention, to access the victim’s system without the victim’s awareness. To do so, the Onyx ransomware camouflages itself in the system so as not to be detected by defense systems. 

In the tactics that depend on the action of a user, phishing tactics are applied so that the victim, without realizing it, downloads the ransomware into the system.

High consumption of processing, memory and disk access are suspicious behaviors that need to be investigated thoroughly in order to assess whether an attack is underway.  

The Onyx ransomware uses the machine’s own resources to perform exfiltration. In order to encrypt the machine this demands the use of its own resources.

It is also possible to detect the Onyx attack by the changes made to the file extensions, this type of detection is a bit more complex because the encryption process will have already been started.

If a device is affected by Onyx ransomware that uses encryption, the encrypted data will remain inaccessible until the ransom is paid or the device is formatted.

However, if the attacking group employs the double extortion tactic of copying and exfiltrating all files from the device prior to encryption, they may post the stolen files on the group’s website or on Dark Web forums. In this case, even if the victim pays the ransom or formats the affected device, the original data will remain encrypted while the stolen files will be exposed, causing significant data breaches and privacy concerns.
