Ransomware
If your files have been encrypted, we accept the challenge of analyzing your case.

BitLocker Ransomware

The BitLocker ransomware has exploited known vulnerabilities in Microsoft Exchanges, these vulnerabilities became known as ProxyShell, this name was given to the combination of three vulnerabilities: CVE-2021-34473, CVE-2021-34523 and CVE-2021-31207.

BitLocker different from other groups uses a tool of Windows itself to encrypt the files, tool that gives the group its name.

This encryption tactic requires a little more from the group, because it needs to take control of the system through remote access, so it can perform the encryption. Even if the BitLocker program is disabled, the malware executes commands to enable it.

The fact that the group has to control the system remotely is worrying, because it doesn’t just use this “privilege” to activate encryption, through it the malware moves laterally in the system looking for backup systems and domain controllers.

This process is time consuming, it can last a few hours. And when the encryption process is finished all systems are locked down and a ransom note is left on the desktop containing information for the victim to contact the group.

The ransom is charged in cryptocurrencies and can vary according to the size of the company and the amount of files that have been encrypted. The value is usually around the thousands of dollars.

In cases where even the backup is encrypted it may seem that the only way out is to pay the ransom, but know that it is not. Digital Recovery specializes in ransomware encrypted data recovery, we can recover files that have been encrypted by Bitlocker ransomware on any storage device.

Ransomware Recovery FAQ

Every day, ransomware attacks get better and better. After a successful attack attempt, ransomware quickly maps the user’s most important files to begin encryption. Microsoft Office files, databases, PDFs and design are among its main targets.
Ransomware is designed to go unnoticed, so it can disable all system defences without being noticed and start the process of encrypting files. Even if ransomware goes unnoticed by the system, it can be noticed by the user, as it uses system resources to perform the encryption, which can slow down the system. Ransomware also changes file extensions. So look out for these signs: slowing down the system and adding extensions to files. To find out more, talk to our experts.
Yes, this is possible. You can restart the computer in safe mode, which will limit the action of the ransomware since the system resources will be locked. You can also disconnect the computer from the Internet, which can interrupt the hackers’ connection to your system, it should be noted that there are ransomwares that work even without being connected to the Internet. You can also run diagnostics to identify threats with your antivirus software, the vast majority of antivirus software have this function. But there are cases where the encryption was interrupted by the user, some files had already been affected and this caused an error in the encryption and the hackers could not restore the files, even with the decryption key. In these cases, only a data recovery company, such as Digital Recovery, can recover the files. To find out more, talk to our experts.
Yes, the attacks mainly take place on holidays and weekends, in the early hours of the morning. These days are chosen because there are not many active users on the system, making it impossible to discover the attack before the encryption is complete. To find out more, talk to our experts.
The vast majority of ransomware uses RSA [Rivest-Shamir-Adleman] -2048 and AES [Advanced Encryption Standard] encryption. To find out more, talk to our experts.
First of all, do not pay the ransom. No matter what the hackers say, there is no guarantee that the decryption key will actually be released after the ransom is paid. The first thing to do is to inform the authorities about the attack. Governments have specialised cybercrime departments that will investigate the attack. Next, check if your backups have been affected, if so, only a specialist data recovery company can recover your files, this is the next step. Contact Digital Recovery who will assist you in the full recovery of your files. To find out more, talk to our experts.
After contacting us and sending the affected media, we will diagnose the device to verify the extent of the damage caused by the ransomware, which will allow us to predict the duration of the process and provide the client with a budget. Once the budget is approved by the client, we begin the recovery process, for which we have proprietary software that can, with the help of our specialists, reconstruct the data. If the client opts for remote recovery, instead of sending us the media, they will send the encrypted files to a virtual environment, totally secure, so that we can access them. At the end of the process, we will perform a double check so that the customer can verify the integrity of the recovered files. Payment is only made once the files have been delivered and validated by the client. To find out more, talk to our experts.
