Angler
Angler was one of the leading exploit kits used by cybercriminals to distribute malware ranging from ransomware and banking Trojans to ad fraud. Like most other exploit kits, it focused on web-based vulnerabilities in the browsers and their plugins. Angler was one of the few exploit kits during its time that offered fileless infections, where malware never touches the disk and only resides in memory to avoid detection. Angler has been inactive since June 2016.
