What is Unrans ransomware? And how does it carry out its attack?
Unrans ransomware or unrans script is a PowerShell script ransomware that not only targets computers but could also target servers as well. This PowerShell script ransomware uses the AES encryption algorithm in encrypting files. Once it is able to infiltrate a system, it will begin searching for certain file types to encrypt like images, audio files, videos, documents, database and more. After it encrypts the files, Unrans ransomware will deliver its ransom note in a file named RansomText.txt which includes a link to a Tor website containing the following content:
“Ransomware! Your personal files have been encrypted!

As you can see, its ransom note contains detailed instructions on how to pay the ransom. The crooks behind this ransomware also offer to restore one file which must be smaller than 5MB. Even so, you must not, under any circumstance, pay the ransom as it does not really guarantee that you’ll get your files back. There are other alternative ways you can use to recover your files, one of which will be provided later on after you follow the Unrans ransomware removal instructions.
How does Unrans ransomware disseminate its malicious payload?

Usually, cyber crooks disguise the email to be something of importance to lure users into opening it and download the corrupted attachment. This corrupted attachment will be the one to launch the attack by connecting to a remote server where it downloads Unrans ransomware and install it into the infected system.
