Recover Unknown ransomware files

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

Ransomware attacks have become one of the most dangerous digital threats, significantly increasing in recent years and impacting companies across all sectors and sizes. Recent studies show that over 70% of these attacks result in full data encryption, causing about 56% of victims to give in to criminals’ demands. Fortunately, there are effective solutions to recover files without negotiating with hackers. Unknown ransomware represents a sophisticated threat designed to completely block access to important files, whether on corporate or personal devices, through robust encryption. Recently, this type of ransomware has gained attention due to its destructive impact, seriously affecting essential sectors such as healthcare, education, industry, and financial markets.

Unlike traditional viruses, Unknown 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.
It is also quite common for ransomware to employdouble extortion strategies, where criminals copy important files before encrypting them, using the threat of public exposure of stolen data as an additional pressure tactic on 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 Unknown ransomware attack work?

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

  • Silent infiltration: The attack starts with phishing techniques, where malicious emails or infected attachments are sent to victims. Another common method involves exploiting technical vulnerabilities in outdated systems, such as software breaches or insecure remote access (RDP).
  • Backup mapping and neutralization: After initial infiltration, the ransomware performs detailed mapping of the internal network, targeting strategic files and available or online-connected backups, aiming to neutralize these backups to prevent rapid recovery.
  • Mass encryption of files: Following initial reconnaissance, ransomware immediately encrypts the identified files. Critical data, databases, ERPs, virtual machines, and RAID arrays are frequently compromised, completely blocking user access.
  • Financial extortion: After encrypting the data, criminals leave a ransom note demanding payment. Usually, instructions for communication through secure platforms or the dark web are provided, requiring payments in cryptocurrencies to hinder tracing.

How much does it cost to decrypt Unknown ransomware?

The precise cost for recovering files encrypted by Unknown ransomware varies depending on the severity and specific technical characteristics of the attack. Typically, the cost is directly influenced by factors such as the volume of data affected, the type of system impacted (servers, storages, virtual machines, or databases), and the availability of intact backups. If you want to quickly start recovery and obtain an accurate quote, contact our specialized team to perform a detailed initial diagnosis. Talk to our specialists now.

How long does the data recovery take?

The period required to restore files can vary significantly depending on the specifics of the attack. Usually, the process takes from a few days to a few weeks, with the exact time influenced by factors like the amount of encrypted data, the complexity of the attack, the size of the affected network, and the quality of existing 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?

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. 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 Unknown ransomware attack?

Preventing a Unknown 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 Unknown 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, Unknown 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.

Unknown 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.

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.
