[Overall Ransomware Statistics]
The total number of new ransomware samples collected during the past 6 months is as follows.
In September, the number of new samples decreased compared to August. This is due to the fact that the quantity of MedusaLocker ransomware, which was temporarily identified only in August, was not detected in September. We will take a closer look at the malware comprising the number of new samples in September in the section “3. New Samples by Ransomware”.
