Cryptovirus Data Recovery. First reaction

The first reaction in the cryptovirus data recovery must be:

Do not delete the files that the hacker has deposited in your encrypted folders!
Do not format your computer!
Do not remove anything from your infected drive!

Then you must call Logirobotix!

In recent years, viruses called “ransomware” (combination of the words “ransom”, which means ransom, and “malware”, infected software) have spread that block the user’s access to their computer by encrypting data and requesting a ransom to be able to decrypt them.

If the ransom is not paid by a set date, the decryption key is destroyed and the files will be lost forever. The ransom is often requested in bitcoin, the electronic money also used in the darknet because it guarantees the total anonymity of the possession and transfer of sums of money.

The most common ransomware out there is called Crypto Virus and is also known as CryptoLocker.

Cryptolocker infection can be prevented?

Unfortunately, having an antivirus installed on your PC is not enough, unless a periodic saving of data in the cloud is foreseen, thus guaranteeing its subsequent recovery. Therefore we recommend that you pay close attention to the sites you visit and the programs or updates you download if they come from unsafe sources, as well as carefully examine the emails received, as the links or attachments could contain this virus.

  • be wary of files and updates downloaded from unsafe sources
  • do not click on links to suspicious websites or e-mails
  • keep in mind that cryptoviruses can also be installed on USB sticks and external devices
  • back up files regularly, especially the most important ones, on different hard drives or in the cloud

How to recover virus-encrypted files

In some cases the ransom is set at not particularly expensive figures and, also considering the short ransom countdown, there have been many cases of users who have decided to pay to get their data back. We tend to discourage payment, obviously there is no guarantee that once paid you will receive your files back.

If you have been affected by this type of infection, you must promptly contact a specialized structure, which has the know-how and tools suitable for managing a particularly difficult type of malware. We also offer a cryptovirus data recovery service.

But how does the recovery happen? In the event of a cryptovirus infection, the only way to decrypt the data is to find the encryption key (which is often hidden among the various encrypted files.). In some cases the cryptographic algorithms may contain writing errors, thanks to which it is possible to unlock the files and eliminate the cryptovirus. The first fundamental step is therefore to try to identify the variant of the cryptovirus with which you are dealing (if it is a note). It is often possible to do this by analyzing the extension of the encrypted files or the files containing the instructions for the ransom. Success in recovering ransomware-encrypted data depends a lot on how refined the variant of the virus is. For this reason, if you have stumbled upon cryptolocker or a variant of it, call us!
