Enlarge JumpCloud, a cloud-based IT management service that lists Cars.com, GoFundMe, and Foursquare among its 5,000 paying customers, experienced a security breach carried out by hackers working for a nation-state, the company said last week. The attack began on June 22 as a spear-phishing campaign, the company revealed last Wednesday. As part of that incident, JumpCloud said, the “sophisticated nation-state sponsored threat actor” gained access to an unspecified part of the JumpCloud internal network.
