Decrypt Bonsoir ransomware files

We have developed exclusive solutions that enable the recovery of Bonsoir encrypted files.

In recent years, ransomware attacks have emerged as a prominent and highly destructive form of cyber attack. An unprecedented number of companies have been subjected to complete data encryption following cyber attacks.

Numerous Bonsoir cyber attacks are tailored and directed towards specific victim companies, with the potential for immense destruction. These attacks often involve a deliberate delay in the encryption process, as the attackers attempt to first gain access to online backups and as many network devices as possible. This can result in the encryption process lasting for months, and once the ransomware is executed, it has the capability to encrypt the majority, if not all, of the data files.

In the face of such a disastrous event, the options available for organizations are often limited, especially if their backup systems have been impacted or are not updated. The alarming number of companies that have been forced to shut down operations after their data has been encrypted is a stark reminder of the devastating impact of these attacks.

Often, even after paying the Bonsoir ransom, the criminals do not provide the decryption key, leaving the victims with no recourse or higher authority to turn to.

Digital Recovery has introduced solutions to the market that can successfully decrypt files affected by ransomware. Our recovery projects have yielded impressive results, with a proven track record of success.

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?

Few companies in the world are able to decrypt Bonsoir ransomware files, so information about this possibility is scarce, to the point that many think that such a recovery is impossible. Also, there is a lot of incorrect information stating that decryption is not possible.

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.

In light of these challenges, it is crucial to seek out reputable companies with significant experience in the data recovery industry, and that provide direct access to a dedicated expert from the initial point of contact. This ensures that customers can trust the expertise and reliability of the company, and receive the support they need to navigate the recovery process.

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 recommend that the victim should not contact the Bonsoir 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 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.

There are several strategies employed by Bonsoir 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 Bonsoir 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 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.

If a device is affected by Bonsoir 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.

Through unique technologies Digital Recovery can bring back encrypted data on any storage device, offering remote solutions anywhere in the world.
