GDCB File Recovery

What is a .GDCB file?

A GDCB file is a file encrypted by the GandCrab virus, a trojan horse utilized by cybercriminals. It contains a user's file, such as a .PDF or .WMV file, encrypted with the Salsa20 algorithm. GDCB files became prevalent in January 2018.

What Are Common Causes of ".GDCB" Files Lost or Failure?

The ".GDCB" file extension is associated with the GandCrab ransomware, which encrypts users' files and demands a ransom for their release. Therefore, the most common causes of ".GDCB" files being lost or failing are:

  1. Ransomware infection: The primary cause of ".GDCB" file loss is the infection of a computer or network by the GandCrab ransomware. This malware encrypts files on the infected system, appending the ".GDCB" extension to their original filenames.
  2. Phishing emails and malicious downloads: Users often unknowingly download the GandCrab ransomware by clicking on malicious email attachments or downloading infected files from untrusted sources. This can lead to the encryption of their files and the loss of access to them.
  3. Exploiting software vulnerabilities: Cybercriminals can exploit vulnerabilities in software or operating systems to gain unauthorized access to a system and install the GandCrab ransomware. Once installed, it encrypts the files, resulting in file loss or failure.
  4. Lack of security measures: Failure to implement adequate security measures such as antivirus software, firewalls, and regular software updates can leave a system vulnerable to ransomware attacks. This can lead to the loss of ".GDCB" files.
  5. Weak passwords and poor authentication: Using weak passwords or not employing multi-factor authentication can make it easier for attackers to gain unauthorized access to a system and deploy ransomware. Subsequently, ".GDCB" files can be lost or become inaccessible.
  6. Lack of user awareness: Users who are unaware of the risks associated with clicking on suspicious links, downloading files from untrusted sources, or opening phishing emails are more likely to fall victim to ransomware attacks. This can result in the loss of ".GDCB" files.

To prevent ".GDCB" file loss, it is crucial to maintain up-to-date security measures, regularly backup important files, exercise caution while browsing the internet and opening email attachments, and educate users about cybersecurity best practices.

How to recover lost ".GDCB" files?

Sometimes while working with a computer, laptop or other stationary or mobile devices, you may encounter various bugs, freezes, hardware or software failures, even in spite of regular updates and junk cleaning. As a result, an important ".GDCB" file may be deleted.
