This shows how attackers are moving from the opportunistic and quantity-focused model to more targeted modern ransomware methods and big-game hunting.<\/p>\n<p>Both premodern and modern ransomware are among the top 10 most detected for the first half of this year. The premodern ransomware WannaCry (aka WCry) still tops the list, although detections for it significantly dipped.
