Recover Kronos ransomware files
If you have been affected by Kronos 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.
Kronos 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.
While common viruses generally aim to cause general damage, Kronos 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 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
The Kronos 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 Another common strategy includes exploiting technical vulnerabilities in outdated systems, such as flaws in old programs or insecure remote access (RDP).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 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: 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: 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 Kronos ransomware?
Determining the precise cost of recovering files affected by Kronos ransomware directly depends on the scope and technical complexity of the incident.
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.
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 time needed for data recovery can significantly vary according to the specific scenario of the suffered attack. On average, the process usually takes from a few days to a few weeks. The exact duration will depend on factors such as the volume of encrypted files, the size of the affected infrastructure, the technical complexity of the ransomware, and the availability or state 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.
Nonetheless, Digital Recovery has specialized and exclusive technologies, such as the proprietary TRACER solution, achieving a high rate of success in recovering files encrypted by ransomware.

What you need to know
How to prevent a Kronos ransomware attack?
Preventing a Kronos 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 Kronos 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, Kronos 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 Kronos 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 Kronos 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 Kronos 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 Kronos ransom?
If a device is affected by Kronos 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.
