What is .sell File Extension ransomware? And how does it carry out its attack?
.sell File Extension ransomware is a new variant of the infamous Paradise ransomware. Just like its previous version, this new variant is being offered as ransomware-as-a-service or RaaS. According to researchers, the activity of this ransomware is still quite low so it isn’t widely spread yet.
.sell File Extension ransomware begins to carry out its attack by dropping several malicious files in the infected computer.

“Your files are encrypted!
