FortiGuard Labs recently detected new versions of Kraken Cryptor Ransomware. While the beta tag has been removed from its configuration, there are still numerous bugs in this ransomware, and the author is still continuously modifying its basic functions.


This ransomware variant is relatively new, only starting to spread this past August. It is obvious that this ransomware is still under construction and that the author is continuing to add new methods to improve its functionalities.
