Recover CrySiS ransomware files

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

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. CrySiS ransomware is an advanced form of malware specifically designed to encrypt essential files on business and personal systems, making them completely inaccessible to their owners. This ransomware has become widely known for its ability to cause significant disruptions to critical operations, particularly affecting sectors such as healthcare, manufacturing, education, and finance.

While common viruses generally aim to cause general damage, CrySiS ransomware is executed by specialized hackers who use advanced encryption techniques, such as AES-256 or RSA, to permanently block access to information, releasing it only upon possession of the specific key under the criminals’ control.
Additionally, hackers often apply the double extortion method>, encrypting files while simultaneously stealing sensitive data, and threatening to publish it online to increase pressure for ransom payment.

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.

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

Answers from our experts

How does the CrySiS ransomware attack work?

The CrySiS ransomware attack typically occurs in several well-defined stages:

  • 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 Another common strategy includes exploiting technical vulnerabilities in outdated systems, such as flaws in old programs or insecure remote access (RDP).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: 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: 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 CrySiS ransomware?

The exact value to decrypt files impacted by CrySiS ransomware is defined according to the extent and level of technical complexity of the suffered 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 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. Once we perform the initial diagnosis, which occurs within the first 24 business hours after your contact, we will provide a precise and detailed estimate of the timeframe necessary to successfully complete your data recovery.

Is there any guarantee for data recovery?

Due to the technical complexity involved in ransomware attacks, no serious company can ensure beforehand the full recovery of encrypted files. Each attack possesses specific characteristics, including distinct encryption algorithms and various strategies adopted by criminals. However, Digital Recovery uses advanced and exclusive technologies, such as the proprietary TRACER solution, which provides a very high success rate in recovering files encrypted by ransomware.

How to prevent a CrySiS ransomware attack?

Preventing a CrySiS 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 are several strategies employed by CrySiS 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 CrySiS 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 CrySiS 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 CrySiS 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 CrySiS 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.
