Recover Onyx ransomware files

If your data has been encrypted by Onyx ransomware, you need to act quickly.

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.

Unlike traditional viruses, Onyx ransomware is controlled by specialized criminal groups that use advanced encryption algorithms, such as AES-256 or RSA, to lock access to data, with the unique key kept exclusively by the attackers.
Another frequently used practice is the double extortion, in which attackers not only encrypt files but also extract and threaten to publicly disclose confidential data, further pressuring victims.

Ransomware attacks have shown accelerated growth, increasing approximately 5% in the past year alone, with the average ransom demanded by criminals reaching millions of dollars. Many organizations, due to lack of effective recovery methods, end up yielding to the demands and funding further attacks.

Our company has innovative and secure solutions for complete ransomware decryption.

Answers from our experts

How does the Onyx ransomware attack work?

Usually, the Onyx ransomware attack occurs through specific and well-structured stages:

  • Silent infiltration: Initially, the ransomware infiltrates through phishing campaigns, sending fraudulent emails or malicious attachments to victims. Another common approach involves exploiting existing technical vulnerabilities in outdated systems, such as software security flaws or unsecured remote connections (RDP).
  • Backup mapping and neutralization: After entering the network, the ransomware performs a meticulous internal reconnaissance, identifying strategic data and connected or online backups. Its main goal is to compromise existing backups, preventing immediate file recovery.
  • Mass encryption of files: Once data is mapped, ransomware quickly starts encryption. Critical files, databases, enterprise resource planning (ERP) systems, virtual machines, and RAID systems are typically affected, making the files completely inaccessible.
  • 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 expedite the process and obtain a precise and personalized assessment, we recommend contacting our specialists directly for an initial diagnosis. Request specialized support right away.

How long does the data recovery take?

The estimated time to recover encrypted data directly depends on the characteristics of the incident. Usually, recovery may take between a few days and a few weeks, varying according to the total volume of compromised files, the technical complexity level of the ransomware, the extent of the affected infrastructure, and the state of available backups. Right after the initial diagnosis, conducted by our specialized team within the first 24 business hours of your contact, you’ll receive a detailed and personalized forecast of the time required to finalize the recovery process.

Is there any guarantee for data recovery?

Due to the technical nature of ransomware attacks, no responsible company can promise a 100% upfront guarantee of full data recovery. Each attack has its own technical peculiarities, such as different encryption algorithms and methods used 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.

  • Organization – Having documentation of the IT park helps a lot in the prevention process, in addition to the inventory of networks and computers. Develop rules so that new employees have clear company policy on the installation and use of programs on computers.
  • Strong Passwords – Passwords should be strong, containing more than 8 digits, including special ones. And do not use a single password for multiple credentials.
  • Security Solutions – Have a good antivirus installed, keep all programs up to date, especially the operating system. Besides the antivirus solution, you need a Firewall and endpoints. They will make sure that the system stays protected.
  • Beware of suspicious emails – One of the most used means for invasion used by hacker groups are spam email campaigns, so it is vital to create a security and awareness policy for employees not to download attached files sent by unknown emails.
  • Efficient backup policies – Backups are essential for any eventual incident, but even with this essential role many companies neglect it or create a backup schedule that is not effective. We have already assisted several clients that not only the data was encrypted, but also the backups. It is not recommended to keep online backups only. The best backup structure is 3x2x1, which is 3 backups, 2 online and 1 offline, in addition to creating a consistent routine of updating the backups.
  • Beware of unofficial programs – There are numerous paid programs that are made available for free on the Internet, such as Windows, Office and many others. They may appear to be free at first, but in the future can be used as a gateway for future hacker attacks. Even if official programs demand financial resources, they are a good investment and are also secure.

There exist various tactics utilized by Onyx criminals, the primary ones being: dissemination of infected files, malicious hyperlinks, RDP-based assaults, phishing, spam email campaigns, among others.

Their ultimate objective is to infiltrate the victim’s system without their knowledge. Therefore, Onyx ransomware disguises itself within the system to evade detection by security systems.

In situations where user involvement is required, perpetrators employ phishing techniques to induce the victim into unwittingly downloading ransomware onto their system.

Suspicious activities such as excessive processing, memory usage, and disk access warrant a thorough investigation to determine whether an attack is in progress.

Onyx Ransomware typically utilizes the machine’s own resources to carry out data exfiltration and encryption, thereby imposing a heavy load on the system’s resources.

Moreover, detecting the attack through changes to file extensions can be challenging since the encryption process would have already been initiated, making it a more complex process.

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.

But in cases where the attacking group uses the double extortion tactic of copying and extracting all files and encrypting the original data, the stolen files will be posted on the group’s website or Dark Web forums and all original data will remain encrypted on the affected device, requiring the device to be formatted.
