Japan Firms Compensate Users After Cyber Chaos

Japanese companies are implementing compensation measures for customers affected by a series of disruptive cyberattacks. GMO Internet Group announced that customers will receive 5,000 yen as an initial goodwill payment following unauthorized access to its foreign exchange trading service. This initiative aims to address losses stemming from recent cyber incidents.

The nation is bolstering its cyber defenses, with plans to establish a team that will simulate cyberattacks using AI to identify vulnerabilities in technology systems. This move comes amid concerns over flaws in the PHP programming language, which underpins a significant portion of the internet, and has led to widespread hacking attempts globally.

Recent cybersecurity incidents have highlighted vulnerabilities in Japanese firms' ability to protect customer data. TrendAI reported 723 cybersecurity incidents by October 20, 2026, surpassing previous annual totals. Park24, operator of the Times car-sharing service, also announced 3,000-yen payments to customers after a personal data breach, expecting a 5.5 billion yen loss.

Experts note that AI is automating cybercrime tasks, making attacks faster, cheaper, and harder to detect. Companies with robust defenses are better positioned to manage these escalating risks, while those with weak security practices are increasingly vulnerable, according to Moody's Ratings.
