Recover Sunjun ransomware files
Have your files been locked by Sunjun ransomware? Act fast to safely restore your data.
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.
Sunjun 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, Sunjun 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.
It is also quite common for ransomware to employ double 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.
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.
Our company has innovative and secure solutions for complete ransomware decryption.

Answers from our experts
Sunjun 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 Another common method involves exploiting technical vulnerabilities in outdated systems, such as software breaches or insecure remote access (RDP).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 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: 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: Upon completion of file encryption, criminals typically leave a ransom note demanding payment. Generally, instructions guide victims to communicate through secure channels or the dark web, specifying cryptocurrency payments to hinder financial tracking.
How much does it cost to decrypt Sunjun ransomware?
The precise cost for recovering files encrypted by Sunjun 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.
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 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.
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?
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.

What you need to know
How to prevent a Sunjun ransomware attack?
Preventing a Sunjun 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 Sunjun 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, Sunjun 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 Sunjun 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 Sunjun 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 Sunjun 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 Sunjun 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.
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.
