Cryptovirus Data Recovery. First reaction

If you have become a victim of a cryptovirus that has encrypted your files and held them hostage for ransom, your first reaction may be one of frustration, anxiety, and fear. It is understandable to feel overwhelmed by the situation, especially if you rely on the affected files for work, personal projects, or sentimental value.

It is important to take a deep breath and not panic. While the situation may seem dire, there are potential options for data recovery, and it is essential to assess the extent of the damage and take appropriate actions.

The first step should be to disconnect the affected device from the internet and any other connected devices to prevent the spread of the virus. Then, it may be helpful to consult with an expert in data recovery or cybersecurity to determine the best course of action based on the specific type of cryptovirus and the encryption method used.

In some cases, it may be possible to recover encrypted files through backups or decryption tools, while in other cases, it may be necessary to negotiate with the attackers and pay the ransom. However, it is important to note that paying the ransom does not guarantee the return of the encrypted files, and it may also encourage further attacks.

Overall, the key is to remain calm, seek expert advice, and take proactive measures to prevent future attacks, such as implementing robust security measures and keeping regular backups of important files.

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?

Yes, there are several steps you can take to prevent a Cryptolocker infection:

  1. Keep your software up to date: Regularly install updates for your operating system, web browser, and other software programs. These updates often include security patches that can prevent vulnerabilities that Cryptolocker and other malware may exploit.

  2. Use anti-virus software: Install and regularly update anti-virus software to protect your computer against known malware threats, including Cryptolocker.

  3. Exercise caution when opening email attachments: Be wary of opening email attachments, especially if they are from unknown senders or contain suspicious subject lines or messages. Cryptolocker is often spread through infected email attachments.

  4. Back up your data: Make regular backups of your important data and files, and store them in a safe location, such as an external hard drive or cloud storage service. If you are hit by a Cryptolocker infection, having recent backups can help you restore your files without paying a ransom.

  5. Educate yourself: Stay informed about the latest threats and best practices for cybersecurity. This can help you recognize and avoid potential risks, and take appropriate actions if you are ever targeted by Cryptolocker or other malware.

By taking these preventative measures, you can significantly reduce your risk of a Cryptolocker infection and other malware attacks.

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

Recovering virus-encrypted files can be a challenging task, but there are a few potential options you can try:

  1. Restore from backups: If you have been regularly backing up your files, you may be able to restore your encrypted files from a recent backup. Make sure to disconnect the backup device from your computer to prevent the virus from spreading.

  2. Use file recovery software: There are several file recovery software options available that can scan your computer for deleted or lost files, including encrypted files. However, the success of this method can depend on how long ago the files were deleted or lost and how much the virus has damaged them.

  3. Contact a professional data recovery service: If you are unable to recover your encrypted files using the above methods, you can consider contacting a professional data recovery service. They can use advanced techniques to recover your files, although this can be expensive.

  4. Decrypt the files: In some cases, there may be a decryption tool available that can unlock the encrypted files. However, this is not always possible, and you should be careful about downloading decryption tools from untrusted sources, as they may contain malware.

It’s important to note that paying the ransom demanded by the virus attackers is not recommended, as it can encourage further attacks and there is no guarantee that the attackers will actually decrypt your files. It’s always best to try other methods of recovery first.

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!
