Japan plans to create a team of ethical hackers that will use AI to attack the country’s own systems and find vulnerabilities before criminals can exploit them.

The announcement comes as banks, rail operators and government agencies take online services offline to patch two critical flaws in PHP, a programming language used across the web.

Industry Minister Ryosei Akazawa announced the plan on Friday, as Reuters reported. The Information-technology Promotion Agency (IPA), which operates under his ministry, will establish the team in November, Japanese business publication Business+IT reported. It will stage simulated cyberattacks to identify weaknesses that organisations can then fix.
