Cyber-adversaries of the US refined their techniques to become more effective at hacking in 2019, according to the cybersecurity firm Crowdstrike Inc.
Hackers in countries including China, North Korea, Iran and Russia have improved their techniques in the last year, finding ways to attack that yield "more bang for their buck”, said Adam Meyers, vice president of intelligence at Crowdstrike, which released an annual review of cyberthreats on Tuesday. For most of those countries, that included an increased focus on targets such as telecommunications, which have far-reaching uses, he said.
