China tightens control over cybersecurity in data crackdown

The rules would ban private sector experts who find “zero day,” or previously unknown security weaknesses, and sell the information to police, spy agencies or companies. Such vulnerabilities have been a feature of major hacking attacks including one this month blamed on a Russian-linked group that infected thousands of companies in at least 17 countries.
