Seldom do people responsible for launching crippling cyberattacks face justice, but increasingly courts around the world are making examples of the few who do get busted for such crimes. On Friday, a 34-year-old Connecticut man received a whopping 10-year prison sentence for carrying out distributed denial-of-service (DDoS) attacks against a number of hospitals in 2014.

A new phone-based phishing scam that spoofs Apple Inc. is likely to fool quite a few people. It starts with an automated call that display’s Apple’s logo, address and real phone number, warning about a data breach at the company.
