Recovery of files affected by Ransomware
We can recover data encrypted by most ransomware extensions on any storage device
Decrypt ransomware files
Ransomware attacks have become one of the leading and most damaging means of cyber attacks in recent years. There has been an unprecedented increase in the number of companies that have had their data completely encrypted after an attack.
Many of these attacks are specific and targeted to the victim company, such attacks have enormous destructive potential. Not only is the group in no hurry to start the process of encrypting the data, without first reaching online backups and as many devices on the network as possible, this process can last for months, and when the ransomware is executed it can encrypt the vast majority of the data or even 100% of the files.
Every day new groups emerge with increasingly complex and dangerous tactics, in addition to these new groups, old and already consolidated groups continue their waves of massive attacks led by the LockBit ransomware, which today is already in version 3.0.
In addition to LockBit ransomware, there are major groups active, including: WannaCry, HiveLeaks (Hive), Royal, ALPHV BlackCat, Play, Bian Lian, Black Basta, Karakurt, and many others. These are just the most active groups in recent months, but as the relevance of these groups grows, new groups are inspired and emerge.
In the face of something so disastrous, there is little that can be done, especially if backups have been affected or are not up to date. The number of companies that shut down after having their data encrypted has reached staggering numbers.
In many cases, even after payment of the ransom, the decryption key is not sent by the criminals, and in these cases there is no higher authority to turn to. In view of this, decryption of the files can only be done by specialised companies such as Digital Recovery, recovery of encrypted files requires advanced technology that can be applied to the encryption done by the ransomware.
Digital Recovery comes to the market with solutions capable of decrypting files affected by ransomware. We have solid numbers in our recovery projects.
Why Digital Recovery?
With more than 23 years of experience, we have accumulated satisfied customers around the world. We can run most of our solutions remotely, and we have multilingual support.
With the increase of ransomware attacks around the world, we specialize in ransomware decryption. We have developed a unique solution that can be applied to the vast majority of storage devices, Virtual Machines, RAID Systems, Storages (NAS, DAS, SAN), Databases or Servers that have been partially or completely encrypted following a ransomware attack, regardless of which group was responsible for the attack.
Working in highly complex environments, we have decrypted the world’s leading ransomware extensions. We have been successful against the major encryption algorithms used by ransomware groups.
Our specialists are highly qualified and have the latest technologies in the data recovery market, the main one is called TRACER, a proprietary technology with which we have obtained expressive results in the decryption of ransomware files.
We offer an advanced diagnosis that will allow us to understand the dimension of the attack, this first diagnosis can be done in the first 24 working hours from the time we receive the samples. After this process, we provide a commercial agreement and, once accepted, we kick off the process of decrypting the files.
We so provide a confidentiality agreement (NDA) written by our legal department. But if you feel more comfortable in providing an NDA written by your own company, we are open to analyze and accept it, if necessary.

Soon after a new wave of LockBit 2.0 ransomware attacks, many companies saw their business come to a standstill because of data locked up by encryption. Here is a case of decryption for one of them.
We received a contact from a company that said it had suffered an attack and was unable to continue its activities. When they arrived at their offices just after the weekend, they realized that a large part of their data was inaccessible.
One of the largest River Logistics companies in Latin America contacted us to decrypt files after an attack by Quantum Ransomware. There has been a wave of attacks by the Quantum group targeting several different companies.

Answers from our experts
How do I recover files encrypted by ransomware?
Which ransomware extensions can be decrypted?
We have developed unique technologies for the decryption of ransomware files, our solutions have produced great results against the main ransomware in action. We can apply our decryption in:
- LockBit 2.0
- LockBit 3.0
- LockBit Black
- ALPHV BlackCat
- HiveLeaks (Hive)
- RedAlert (N13V)
- Bian Lian
- RA Team
These are just some of the extensions our experts can work on with our decryption solutions.
How much does the process to decrypt ransomware cost?
It is not possible to state the price of the process before the initial diagnosis, only after it is possible to measure the size of the damage caused by ransomware and analyze whether decryption will be possible or not.
After the initial diagnosis, a commercial proposal is made available and, once accepted, the recovery process is started. In most of the cases the payment is only made after the validation of the recovered files, done by the customer himself in a remote session.
Is negotiating with hackers a good option?
Criminals count on the victim contacting them in the first few hours after the attack, so they use threats expressed in the ransom terms, in this first contact the victim will be under strong stress and may give in more quickly to the criminals’ whims.
We recommend that the victim should not contact the criminals, but contact professionals in this field, so that, accompanied by an expert, they can analyze the data and verify the possibilities of recovery.

What you need to know
Preventing a 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 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 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.
Is there any behavior of my server, that I can analyze, to know if I am being attacked by 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 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 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.
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.
