In Q2 2021, we saw the disappearance of a few different ransomware operations. It is difficult to identify whether the groups simply went into hiding, were arrested, rebranded, or are now operating with a different #ransomware group. The previous three months saw a few groups call it quits including #Avaddon, #Babuk Locker, #DarkSide, and #Astro Locker ransomware groups. In Q2 2021 alone, this included 740 different victims as being named to the various active data leak sites. This is a 47% increase when compared to the same activity identified in Q1 2021.
