Artificial intelligence is allowing cyberattackers to identify weaknesses in computer systems at unprecedented speed and scale, Nikkei reported on November 3, 2026. Security experts have long argued that it is impossible to prevent every hack, and with the rapid evolution of AI, the report said it is time for governments and businesses to strengthen defenses on the assumption that intrusions are inevitable.
