North Korean hackers said to have stolen nearly $400 million in cryptocurrency last year

Hackers launched at least seven different attacks last year, primarily targeting investment firms and centralized exchanges with a variety of tactics, including phishing, malware and social engineering, according to the report from Chainalysis, a firm that tracks cryptocurrency. The cybercriminals worked to gain access to organizations’ “hot” wallets — digital wallets that are connected to the internet — and then move funds into DPRK-controlled accounts.
