Qstx Ransomware is the Latest Djvu Clone

Qstx ransomware is the name of yet another ransomware clone, based on Djvu ransomware code, that was spotted in the wild by researchers.

The Qstx ransomware encrypts files on the targeted system, making them unusable. Encrypted files receive the ".qstx" extension appended past their original one. This will turn a file named "archive.zip" into "archive.zip.qstx" upon encryption.

The ransomware encrypts almost every document, archive, executable, media and database file type.

Once encryption completes, the Qstx ransomware drops its ransom demands inside a plain text file named "_readme.txt". The ransom note follows the usual template shared between all recent Djvu clones. The full note goes as follows:
