Japan Steps Up Cyber Warnings as Data Leaks Affect Millions
Japan has intensified its cyber security warnings following recent attacks that exposed data from millions of customers. Cyberattacks have targeted prominent Japanese entities including Times Car, JR East (a rail operator), and a SoftBank cloud unit. A ruling party official described the situation as a "state of emergency in cyber space", according to the Financial Times (FT).
Recent Attacks and Data Leaks
- Times Car: An attack on the car-sharing service resulted in the leak of data from approximately 6.6 million member accounts, including driving licence images.
- JR East: The rail operator lost 1.67 million customer email addresses.
- SoftBank Cloud Unit (IDC Frontier): A ransomware attack disrupted services for 495 companies and local governments, affecting the logistics system of Nissui Logistics at 17 sites and taking Ibaraki Prefecture's websites offline.
Government Response
Japan's government has urged ministries, local authorities, and companies to bolster their cyber defenses. The National Cybersecurity Office issued instructions on Friday, highlighting the need for:
- Updating security software
- Utilizing strong passwords
- Strengthening security across supply chains
- Awareness of attacks impersonating cyber defense efforts
- Addressing complexities introduced by AI
These measures come into effect following the implementation of Japan's active cyber defence law on October 1st.
Growing Cyber Threat
More than 20 major Japanese companies have disclosed cyberattacks in recent weeks, underscoring a rising trend in sophisticated and widespread digital assaults. Experts note that while AI may play a role, there is currently no definitive evidence linking it to these specific attacks.
Global Impact
South Korea has also faced similar breaches, with CrowdStrike attributing them to AI tools and a suspect based in China. In Canada, AI agents have made failed hacking attempts on the national archive, while Gambit reported that AI agents stole approximately 600,000 credit card records in Canada last month.
