What is Bisquilla ransomware? And how does it execute its attack?

Bisquilla ransomware is a new file-encrypting malware that’s been discovered recently. This new ransomware threat, however, does not really encrypt files on a computer. It is only capable of modifying system settings and fooling users to believe that their files are encrypted when they’re actually not. According to security researchers, this threat was found to be spreading as a fake Google Chrome updater and informs potential victims via a black window message.

Bisquilla Ransomware

The instant its payload file is dropped in a computer, it will quickly modify the settings in the system so that it can manipulate and monitor all the activities. It also modifies the settings in the browser where it will display a black window that contains the following message:

“Please relax and enjoy a warm cup of tea while I encrypt your files.
Do not turn off your computer, this can corrupt your files.
File Encryption Completed

As you can see on its ransom note, it tells users not to turn off their computers so that the files won’t get corrupted. Do not believe any of its words as it’s only bluffing and is only trying to make you believe that your files are encrypted. The best way to deal with threats of this kind is to eliminate them as fast as you can as their creators might decide to update them.
