Attackers are not through testing the limits of what they can do with new features in ransomware samples. That latest found in the wild is called PowerWare and it was discovered a week ago targeting a company in the healthcare industry, researchers at Carbon Black told.

What sets PowerWare apart from other crypto-ransomware samples is that it is fileless, which is a tactic adopted by other malware families pushed in prolific exploit kits such as Angler. Palo Alto Networks, for example, disclosed on March 11 a malware family called PowerSniff that has similar behaviors to PowerWare, including fileless infections.
