Recover Onyx2 ransomware files
If you have been affected by Onyx2 ransomware, it is essential to act immediately to recover your files.
Ransomware has become a critical threat to companies of all sizes and industries due to the significant increase in attacks in recent years. Studies indicate that in over 70% of cases, data is completely encrypted, leading about 56% of victims to pay criminals the ransom. Fortunately, there are effective technical alternatives to recover data without making any payment to attackers.
Onyx2 ransomware is an advanced category of malware that aims to encrypt vital data, preventing legitimate access to information stored in corporate and personal systems. In recent years, this threat has gained significant prominence, severely impacting strategic sectors including healthcare, education, manufacturing, and financial services.
Contrary to common viruses, Onyx2 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.
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.

Answers from our experts
The Onyx2 ransomware attack typically occurs in several well-defined 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 Another common approach involves exploiting existing technical vulnerabilities in outdated systems, such as software security flaws or unsecured remote connections (RDP).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 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: Once the mapping of important files is complete, ransomware promptly initiates its encryption. Vital files including databases, ERP systems, virtual machines, and RAID systems are generally impacted, resulting in complete data inaccessibility.
- Financial extortion: Immediately after data encryption, hackers leave a note demanding ransom payment. Typically, the instructions include communication through secure platforms or dark web sites, requesting cryptocurrency payments to prevent tracing.
How much does it cost to decrypt Onyx2 ransomware?
Determining the precise cost of recovering files affected by Onyx2 ransomware directly depends on the scope and technical complexity of the incident.
Generally, factors such as the amount of data affected, the type of compromised system (servers, virtual machines, storages, or databases), and the availability of functional backups directly influence the final cost.
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.
After our initial diagnosis, performed within the first 24 business hours after your contact, our team will provide a clear and personalized estimate of the time required to successfully complete the process.
Is there any guarantee for data recovery?
Because of the unique technical characteristics of each ransomware attack, it is impossible to guarantee 100% success in data recovery in advance. Each case has its own particularities, such as different encryption algorithms and diverse techniques used by attackers.
Nevertheless, Digital Recovery relies on proprietary and advanced technologies, including the exclusive TRACER solution, capable of providing high success rates in recovering ransomware-encrypted files.

What you need to know
How to prevent a Onyx2 ransomware attack?
Preventing a Onyx2 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.
What is the most common means of access used by hackers to break into the environments?
There exist various tactics utilized by Onyx2 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, Onyx2 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.
Is there any behavior of my server, that I can analyze, to know if I am being attacked by Onyx2 Ransomware?
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 Onyx2 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 Onyx2 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.
What happens if I don't pay the Onyx2 ransom?
The data will remain encrypted, it will be necessary for the affected machine to be formatted. By doing this all stored data will be lost.
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.
