Coinbase has revised its remote work policy following attempts by North Korean IT personnel to exploit it for accessing sensitive systems. CEO Brian Armstrong announced that all employees must now travel to the United States for in-person onboarding training. Employees working with sensitive systems are required to be US citizens and undergo fingerprint verification. The company is collaborating with law enforcement to counter these threats and enhance internal security measures. Coinbase has also expanded its US customer support team and established a new facility in North Carolina to bolster cybersecurity. Employees found leaking sensitive information face serious legal repercussions.
