Japanese Firms Pay Compensation Following Cyberattack Disruptions
GMO Internet and Park24 are offering payouts to customers after recent cyberattacks exposed vulnerabilities and impacted services across Japan.

Company Compensations Begin
Japanese businesses are providing financial redress to customers affected by recent cyberattacks that have disrupted internet services. GMO Internet, a major internet services provider, announced it would compensate users for losses incurred from unauthorised access to its foreign exchange trading platform.
Chief Executive Masatoshi Kumagai stated in a blog post on Sunday that all affected customers would receive 5,000 yen ($32) as an initial gesture of goodwill. This action follows widespread concerns about the stability of Japan's digital economy amidst a surge in cyber incidents.
Market Impact and Software Vulnerabilities
The cyberattack significantly impacted GMO Internet's market performance. Shares of the company, which had a market capitalisation of $2.6 billion at Friday's close, fell by 11% in Tokyo trading this morning. This decline contrasted with the benchmark index, which remained flat.
The incident highlights critical vulnerabilities in the PHP programming language, a foundational element for many internet services, which has led to numerous hacking attempts against government and corporate websites in Japan and Europe in the past week.
Further Breaches and Government Response
GMO Internet also reported receiving a ransom demand from the attackers, threatening to disclose company and customer data if payment was not made. The company confirmed it would not comply with this demand, choosing instead to collaborate with police and other authorities on its response.
Separately, Park24, which operates the Times car-sharing service, announced on Friday that it would issue 3,000 yen payments to customers affected by a personal data breach. Japan's government, responding to these threats, said on Friday it would establish a team to simulate cyberattacks using artificial intelligence (AI) to identify system weaknesses.
Rising Costs for Asian Businesses
The rising frequency and sophistication of cyberattacks, aided by AI automation in vulnerability scanning and phishing, present growing operational and financial risks for businesses across Asia. Companies face increased costs from implementing advanced cyber defence measures, managing service disruptions, and compensating affected customers.
The Japanese government's proactive step to use AI for vulnerability detection shows a recognition of this evolving threat. This trend suggests that firms in the region must allocate greater resources to cybersecurity and incident response, directly impacting their balance sheets and operational resilience.
