North Korean hackers are displaying a “startup mentality” as they experiment with new methods to pull off cryptocurrency heists, a report by cybersecurity firm Proofpoint said Wednesday.

The Sunnyvale, Calif.-based firm said a group they identify as TA444, which overlaps with infamous hacker collective Lazarus, launched a massive wave of phishing attacks in December targeting the financial, education, government and healthcare sectors in the United States and Canada.
