What is Ygvb Ransomware

The number of queries related to new ransomware activity is growing each day with new infections. This time around users are dealing with Ygvb Ransomware, which is a new and dangerous piece developed by the Djvu/STOP family. Its recent activity has encrypted a lot of personal data with strong algorithms. Despite Ygvb Ransomware has not being totally inspected just yet, there are some things that are clear already. For example, the virus reconfigures various types of data (images, documents, databases, etc.) changing original extensions to .ygvb. This means that all types of data will save its initial name, but change the main extension to something like this "1.pdf.ygvb". Once the encryption process gets to a close, you will no longer be able to access your data. In order to regain it, extortionists have scripted the creation of identical notes dropped into encrypted folders or onto a desktop. The name of the note is usually _readme.txt, which contains detailed instructions on how to recover your data.

As developers claim, the only feasible way to decrypt your data is to purchase special software along with the unique key stored on their servers. To disperse any doubts of users, they also offer to test free decryption before buying the whole software. You can choose any blocked file (not valuable) and send it to cybercriminals for free decryption. More likely they will successfully prove their ability of data decryption, however, this does not exclude the risk of being fooled afterward. There have been many scenarios when users did not receive any decryption tools even after paying the ransom. This is why the risk is always present and it is up to you whether to pay the ransom or not. The total price of decryption software equals 980$, however, it can be halved down to 490$ if you contact cyber criminals within 72 hours via e-mail (support@sysmail.ch or supportsys@airmail.cc). Unfortunately, these swindlers are true saying that they are the only figures being able to decrypt your data. At the moment of writing this article, cyber experts have not found a way to decipher the data encrypted by Ygvb Ransomware. As a rule, all Djvu infections are well-developed and contain minimal bugs that could expose their ciphers. In this case, recovering access to blocked data is very unlikely, but still worth trying if you are not ready to pay the ransom. To do this, you should delete Ygvb Ransomware from your computer and use the recovery tools presented below.

How Ygvb Ransomware infected your computer

If you are wondering how ransomware could pounce your system, we have it explained in this section. Usually, file-encrypting programs tend to be distributed via unprotected RDP configuration, e-mail spam letters, keyloggers, trojans, backdoors, fake software cracking tools, malicious ads, dubious downloads, and many more. The most popular penetration out of this list appears to be done via e-mail messages. Extortionists disguise a wide range of e-letters as legitimate campaigns promoting online products. Bundled with malicious attachments, swindlers make everything possible to force users into downloading or interacting with them. The hidden malware is often included in MS Office documents, PDFs, executables, and JavaScript files. Thus, whenever you see an ostensibly legitimate message asking to open a file or follow suspicious links, more likely it is meant to deliver ransomware or other types of malware. Overall, in order to prevent ransomware from reaching your data, you should be more careful whilst using the web. Never open or download content spread by unknown and dubious resources. In addition to that, it is highly recommended to use anti-malware software that warns and blocks users from facing potentially dangerous content. We offer a couple of high-end software that will be useful in combating such threats in the future. Both removal instructions and protectionary tools can be found below.
