We can retrieve data encrypted by Bonsoir ransomware on the majority of the storage devices
Decrypt Bonsoir 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 Bonsoir 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.
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 Bonsoir ransom, the decryption key is not sent by the criminals, and in these cases there is no higher authority to turn to.

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 affected by Bonsoir ransomware?
The recovery of Bonsoir ransomware files is only possible because we have developed a proprietary technology that allows us to locate the encrypted files and reconstruct them, in many cases.
Successful recovery of encrypted ransomware files requires knowledge about the specific storage device that was affected. Our experts possess extensive knowledge and expertise in each of the major storage devices, including RAID systems, Storages (NAS, DAS, SAN), Databases, Servers, Virtual Machines, and more. Without this specialized knowledge, file recovery can be compromised and may not be possible.
How to choose a company to decrypt my data?
Due to the limited number of companies with the ability to decrypt Bonsoir ransomware files, accurate information on this process is hard to come by. As a result, many people believe that such recovery is impossible, and there is a lot of misinformation that decryption cannot be done.
And among all these discussions there are serious companies that have developed such solutions, such as Digital Recovery.
Due to the confidential nature of the recovery process and customer information, formal testimonials regarding these processes are limited.
Given all this, it is important that you look for companies that are serious and that have several years of experience in the data recovery market and that make an expert available for the customer to communicate with from the first contact.
How much does the process to decrypt Bonsoir ransomware cost?
The cost of the ransomware decryption process can only be determined after an initial diagnosis, as the extent of the damage caused by the Bonsoir ransomware attack needs to be assessed. This evaluation will determine if the decryption process is possible or not, and the complexity of the process required. As a result, it is not possible to provide an estimate or quote for the cost of the decryption process without first conducting an analysis.
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 from Bonsoir group 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 strongly advise victims of Bonsoir ransomware attacks not to contact the criminals directly but instead seek professional assistance from experts in this field. By contacting professionals, victims can be accompanied by an expert who can analyze the data and evaluate the possibilities of recovery. This approach can help reduce stress and increase the chances of a successful recovery while minimizing the risk of further damage or loss of data.

How to prevent a Bonsoir ransomware attack?
Preventing a Bonsoir 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 Bonsoir 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, Bonsoir 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 Bonsoir 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 Bonsoir 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 Bonsoir 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 Bonsoir 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.
