Japan hit by record cyberattack wave

TOKYO (TR) – Publicized cyberattacks and corporate data breaches across Japan surged to an all-time monthly high of 233 incidents last month.

Researchers are warning of a dangerous escalation driven by autonomous “AI agents,” reports TV Asahi (Nov. 9).

According to findings by cybersecurity firm Trend Micro, the figure represents a staggering 2.4-fold increase compared to the previous record set in September two years ago. The wave of digital breaches has also shattered the country’s annual record.

Security researchers identified attacks utilizing autonomous AI agents — programs capable of executing decisions and conducting intrusions without human intervention — as a key driver behind the sudden spike in compromised data.

The fallout has been catastrophic: approximately 185 million pieces of personal information were leaked over the course of last month alone, nearly doubling the volume compromised during the previous month.

The unprecedented surge highlights a grim reality for domestic organizations, exposing that conventional cybersecurity protocols and data management practices are no longer capable of defending against modern, automated cyber assaults.
