Remove CRYPTBD ransomware and restore encrypted data

CRYPTBD ransomware removal and files recovery guide

CRYPTBD ransomware is a cryptovirus belongs to MedusaLocker ransomware group. The malware is designed to encrypt stored files and then demand ransom payment for the decryption.  Each encrypted file by CRYPTBD ransomware will receive .CRYPTED extension. For example, a file 1.jpg would appear as 1.jpg.CRYPTED, 2.jpg as 2.jpg.CRYPTED and so on. After finishing the encryption process, the ransomware drops HOW_TO_RECOVER_DATA.html on each compromised folder.

The ransom note (HOW_TO_RECOVER_DATA.html file) states that the victims’ systems have been infected by ransomware. The stored data have been encrypted using RSA and AES encryption algorithms. Additionally, all confidential data stored on the network have been ex-filtrated. They are asked to send unspecified ransom money, to recover the files.  Also, they are threatened to publicize these data if they ignore the ransom payment instruction.

To initiate the recovery process, they are asked to communicate them via provided email address within 72 hours. If the time elapsed, the price will be increased.  Further, the victims are alerted that the decryption tools are only stored temporarily. They are asked to test the decryption by sending up to encrypted files before paying the ransom. The message ends with a warning not to rename, modify and/or attempt to decrypt the files filed with third-party tools/ software – this will render the files permanently inaccessible.

Unfortunately, in most cases with ransomware infection- the files decryption is not possible without the involvement of the crooks behind it. It might be when the ransomware is at its initial stage or has some bugs/ flaws in them. Regardless, it is expressly advised against communicating with and/or paying criminals. Since often, despite meeting the ransom demands, the victims receive no decryption keys/ tools. Thus, the people who pay experience financial loss and their files remain useless. Removing CRYPTBD ransomware will also not decrypt the encrypted files. However, this is a crucial process to do to avoid major issues that the malware presence may cause to the system. To get the files, you can rely on backup you have.

Other than backups, Volume Shadow Copies are option available for you. These are automatically created backups from operating system. You will find the instruction below the post in the data recovery section to how to recover files using shadow copies. In some cases, ransomware deletes the shadow copies as well. If this is so with CRYPTBD ransomware, and in case you have backups available, you have to rely on third party data recovery tool. Nowadays, several tools are available with the capability to recover the damaged, deleted or corrupted files on systems.

How did CRYPTBD ransomware infiltrate my computer?

Ransomware and other malicious malware are often distributed via untrustworthy downloading channels such as unofficial and free-file hosting sites, p2p networks and other third-party downloaders/ installers. Malicious programs are typically disguised as legit and ordinary or are bundled with regular software and therefore, users often download/ install them inadvertently. Illegal activation tools and fake software updaters are prime examples of malware-spreading content. Cracking tools infect systems instead of activating licensed products. Illegitimate updating tools cause system infections by exploiting bugs/ flaws of outdated software or by installing malicious software rather than updates.

Spam email campaigns are other commonly used ransomware distribute techniques. The scam campaigns refer large scale operations during which thousands of spam emails are designed and delivered. The letters contain infectious files or links for such files as attachments. If clicked, the malicious malware download/installation process is triggered. The malicious files are usually in MS Office Documents, PDFs, Archives, JavaScript and etc.

How to prevent ransomware intrusion?

It is recommended you to use only official websites and direct links for any software download. Additionally, all programs must be activated/ updated using the tools/ functions from official software developers. To avoid infection through spam emails, it is advised to open only those emails whose senders’ addresses are known to you. Spam emails usually have suspicious and irrelevant addresses. The infection could be caused just after clicking such attachments or through the virulent files in them. So, for the better protection, you require employing a powerful antivirus tool that can detect and delete any malware who manages to slip in by bypassing various security settings.
