Qotr Ransomware
Qotr, a variant belonging to the Djvu ransomware family, encrypts data and adds the ".qotr" extension to filenames. Qotr creates a "_readme.txt" file to provide contact and payment information. As an illustration of its file renaming method, Qotr changes "1.jpg" to "1.jpg.qotr", "2.png" to "2.png.
