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

BlockZ Ransomware

BlockZ ransomware has been extremely consistent in its recent attacks, with countless victims emerging with files encrypted by the group.

The group acts mainly with spam and phishing email campaigns, this campaign consists of sending numerous emails with important messages such as from banks, post offices, etc. Requesting the user to download a document to analyse the terms and in that document is contained the malware.

The ransomware does not manifest itself immediately, on the contrary, it hides in the victim’s system and disables the system defences such as antivirus, firewalls and others.

After disabling any program that could counter the encryption process, the ransomware completely maps the most important files such as PDFs, spreadsheets, documents, photos, etc.

After that it immediately starts encrypting the files, this can take some time, all affected files receive the extension .blockZ and are unable to be opened or changed.

After the end of the process a document is generated with the ransom term, called ‘How To Restore Your Files.txt’.

The group charges high amounts to release the key to decrypt the files, the amount must be paid in cryptocurrencies and may vary according to the victim and the volume of encrypted data.

It is worth remembering that criminals do not give any guarantee that the decryption key will be even released after the payment of the ransom, there are numerous cases in which the victim made the payment and continued with the encrypted files.

In view of this, it is vital to know an alternative to payment, this alternative is the recovery of encrypted data made by Digital Recovery.

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.
