The simulated cyberattacks using AI aim to bolster defenses against widespread internet disruptions caused by programming language flaws. The initiative highlights the increasing use of AI in both offensive and defensive cybersecurity strategies.
Japan announced on Friday it will establish a team to simulate cyberattacks using artificial intelligence to identify weaknesses in technology systems. This initiative follows widespread disruptions to global internet services caused by critical vulnerabilities discovered in the PHP programming language.
Millions of hacking attempts were recorded this week, forcing numerous organizations, including government agencies and major companies, to temporarily suspend or shut down their systems. Japanese mobile carrier SoftBank, for example, suspended its emergency alert system for mobile users due to a PHP vulnerability.
