In this week’s Cyber Security Brief, we discuss the latest developments in the SamSam ransomware, with two of the people reportedly behind the ransomware having been recently indicted. Dick O’Brien, Candid Wueest and Brigid O Gorman also discuss the recent huge data breach at the Marriot-owned Starwood chain of hotels, as well as a large breach at Q & A website Quora. The hacker who hijacked 50,000 printers to spam people to support infamous YouTuber PewDiePie, a gaffe by an AI jaywalking detection system in a city in China, and malicious fitness apps on the Apple App Store are also up for discussion.
