Over 70 countries including the UK, EU, China, Russia, and Brazil signed the landmark U.N. Convention against Cybercrime in Hanoi, creating the first global framework to combat digital crime costing $10.5 trillion annually. The U.S. notably did not sign, stating it continues to review the treaty. While supporters say it will help coordinate cross-border law enforcement against ransomware, trafficking, and terrorism, critics warn it could enable surveillance and authoritarian abuse of digital rights.
