In this week’s Cyber Security Brief, Dick O’Brien is joined by Symantec threat researchers Jon DiMaggio and Candid Wueest to discuss the big cyber security stories of the last week. We talk about Symantec’s latest research on a previously-unknown attack group called Gallmaker, which is using “living off the land” and publicly-available hack tools to target organizations in the government and defense sectors. We also discuss the hack of the SpankChain cryptocurrency project, the breach at Garmin-owned boating app Navionics, and how Fitbit data has been used in a murder investigation.
