According to the latest Internet Security Report from data security provider WatchGuard, ransomware at the endpoint level has surged 627% — despite an observed decrease at the network level of detected malware last quarter. What's the explanation? Some 93% of malware is hiding behind encryption, WatchGuard said, and about 80% of the company's customers have not enabled https decryption in their firewalls, so the malware is going largely undetected until it reaches endpoints, where detections increased 22% overall.
