Recover Sunjun ransomware files

If you have been affected by Sunjun ransomware, it is essential to act immediately to recover your files.

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 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 threats, Sunjun ransomware is managed by highly organized criminal groups that employ powerful encryption (AES-256 or RSA) to render data inaccessible except through a unique key held by the attackers.

In addition, the practice known as double extortion is common, wherein besides encrypting files, hackers steal copies of sensitive data to threaten victims with public exposure.

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 offer unique solutions for ransomware decryption.

Answers from our experts

How does the Sunjun ransomware attack work?

Attacks caused by Sunjun ransomware typically follow clear and detailed stages:

  • 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 Another common method involves exploiting technical vulnerabilities in outdated systems, such as software breaches or insecure remote access (RDP).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: 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 Sunjun ransomware?

Determining the precise cost of recovering files affected by Sunjun ransomware directly depends on the scope and technical complexity of the incident.

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.

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.

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?

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.

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

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.

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.

Suspicious activities such as excessive processing, memory usage, and disk access warrant a thorough investigation to determine whether an attack is in progress.

Sunjun 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.
