Recover Hotarus ransomware files

Have your files been locked by Hotarus ransomware? Act fast to safely restore your data.

Ransomware attacks are among today’s greatest digital threats, showing constant growth and affecting organizations of various sizes and sectors. Recent surveys indicate that over 70% of these attacks lead to full file encryption, with around 56% of victims paying the ransom demanded. However, specialized solutions exist that allow data recovery without directly negotiating with hackers. Hotarus 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, Hotarus 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.
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.

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

How does the Hotarus ransomware attack work?

Hotarus 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 Another common method involves exploiting technical vulnerabilities in outdated systems, such as software breaches or insecure remote access (RDP).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: Right after identifying strategic data, ransomware rapidly encrypts the information. Typically, essential files like databases, ERP systems, virtual machines, and RAID systems are affected, making information access impossible.
  • 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 Hotarus ransomware?

The exact cost to decrypt files affected by Hotarus ransomware directly depends on the extent and technical complexity 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. 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 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. 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 nature of ransomware attacks, no responsible company can promise a 100% upfront guarantee of full data recovery. Each attack has its own technical peculiarities, such as different encryption algorithms and methods used 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.

How to prevent a Hotarus ransomware attack?

Preventing a Hotarus 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 Hotarus 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 Hotarus 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 Hotarus 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 Hotarus 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 Hotarus ransomware that uses encryption, the encrypted data will remain inaccessible until the ransom is paid or the device is formatted.

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.
