Recover Kronos ransomware files
In case Kronos ransomware has encrypted your data, rapid response is essential to increase your chances of recovery.
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 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, 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.
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.
The number of ransomware attacks is rapidly increasing, with approximately 5% growth recorded last year. Ransom demands frequently exceed millions of dollars, leading many affected companies to pay the required amount due to ignorance of effective alternatives, directly fueling the cycle of attacks.
We have exclusive technologies for effective decryption and recovery of ransomware-affected data.

Answers from our experts
Kronos ransomware executes its attack through a clear and defined sequence of steps:
- Silent infiltration: The attack usually begins through phishing, by sending malicious emails or infected files to victims. Additionally, technical vulnerabilities in outdated systems, such as breaches in old software or insecure remote access via RDP, are commonly exploited.
- 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: Once files are encrypted, attackers leave a ransom note with detailed payment instructions. Instructions frequently suggest contacting via anonymous platforms or the dark web, demanding cryptocurrency payments to make tracing virtually impossible.
How much does it cost to decrypt Kronos ransomware?
The precise cost for recovering files encrypted by Kronos ransomware varies depending on the severity and specific technical characteristics of the attack.
The final value largely depends on elements such as the extent of compromised data, the specific types of systems involved (servers, virtual machines, storages, or databases), and the current state of existing 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 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?
Considering the technical complexity of ransomware attacks, no responsible company can guarantee in advance the complete recovery of files. Each incident presents unique technical aspects, such as different cryptographic algorithms and specific methods employed 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.

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.
Keep software and operating systems up to date: Regularly update software and operating systems with the latest security patches to protect against known vulnerabilities.
Use strong passwords and two-factor authentication: Use strong, unique passwords for all accounts and enable two-factor authentication to add an extra layer of security.
Educate employees: Train employees on how to recognize phishing emails and other social engineering tactics used by cybercriminals.
Back up data regularly: Make sure to regularly back up important data to a secure, offsite location.
Use antivirus and antimalware software: Use reputable antivirus and antimalware software and keep it up to date.
Limit user access: Restrict user access to only what is necessary to perform their job functions and regularly review and remove unnecessary access.
Monitor network traffic: Regularly monitor network traffic to detect unusual activity or traffic patterns.
Have an incident response plan: Develop and regularly test an incident response plan to respond quickly and effectively to a ransomware attack.
By following these best practices, organizations can help reduce their risk of falling victim to a Kronos ransomware attack.
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?
Suspicious activities such as excessive processing, memory usage, and disk access warrant a thorough investigation to determine whether an attack is in progress.
Kronos 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.
What happens if I don't pay the Kronos 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.
