What is Paas Ransomware

Developed by Djvu, Paas is a ransomware-type virus that targets personal data. Just like other malware of this type, Paas runs data encryption to demand monetary ransom from victims. All files attacked by Paas (including pictures, databases, documents, etc.) will be restricted from access and altered visually as well. For example, a file like 1.pdf will change its look to 1.pdf.paas at the end of encryption. Developers of this ransomware variant apply the .paas extension to each of the target files stored on a system. The next thing it does after manipulating data extensions is creating a ransom note (_readme.txt) that contains decryption instructions. Once users open it up, they will be presented with text written by cybercriminals. This text provides information on how to return the encrypted data.

To do it, victims have to pay for decryption software and keys that will be able to unlock access to data. In order to buy this set of tools, victims have to contact extortionists via e-mail and get payment details. There is also an offer to send 1 file for free decryption prior to paying the ransom. Developers think that such an offer will strengthen the trust of victims towards paying the swindlers. However, despite this, there is no real guarantee that cybercriminals will not fool you eventually. In other words, they can receive your money and forget about sending the promised decryption tools. In some cases, users can avoid paying the ransom if there is a free decryption tool developed by cyber experts. Unfortunately, there is no such developed for Paas Ransomware at this moment. The only feasible way to recover your data barring the ransom is backup storage. You can delete Paas Ransomware from your computer and return the blocked files from backup devices. If you are unable to purchase paid decryption but do not possess any backup copies, you can still give it a try using third-party tools that may be able to recover some of your data. All information on that and else can be found below.

How Paas Ransomware infected your computer

Ransomware infections are commonly spread via e-mail spam, trojans, unprotected RDP configuration, backdoors, keyloggers, fake software installers, and other methods like that. As a rule, most infections happen due to e-mail spam letters. This is because scammers find it to be the easiest way to cover a large number of victims. They send messages pre-bundled with malicious attachments or links leading to download pages. Usually, e-mail services do not let others attach potentially dangerous files. However, cybercriminals change file extensions and configurations intentionally to avoid malware protection. This is why they attach ostensibly authentic file formats like MS Office documents and PDFs (sometimes .exe or .js files). Depending on which e-mail service you use, developers provide different protection layers. Less popular services are more likely to be vulnerable to malicious attachements. Whatever the case, it is important to be cautious no matter which service you use. Never open such attachments received from unknown sources as they might contain virus infections. It is important to note that cybercriminals tend to use names similar to official companies that promote their products. Keep in mind that no official company will send you suspicious files like mentioned above. Below, we will show you the ways to protect your e-mail and system from potential malware attacks.
