A decryptor for the STOP Ransomware has been released by Emsisoft and Michael Gillespie that allows you to decrypt files encrypted by 148 variants of the infection for free. While the decryptor can recover files for 148 variants, it needs to be noted that anyone who was infected after August 2019 cannot be helped with this service. The number of victims is hard to determine, there have been 116,000 submissions to ransomware identification site IDRansomware related to this infection. Most victims are from Europe, Asia, South American, and Africa.
