Japan Urges Stronger Cybersecurity After Wave of Data Breaches
Japan has been dealing with many computer attacks against companies and public organisations.
These attacks may have exposed information belonging to millions of people.
Japan’s financial regulator wants banks to use identity documents with electronic chips instead of relying mainly on driving licences.
Officials say the problem is serious and affects more than just individual businesses.
Older computer systems and weak security practices may make some organisations easier to attack.
Experts also say artificial intelligence could help criminals prepare attacks more quickly.
But they have not found clear evidence that AI caused the recent attacks in Japan.
Better identification checks may help, but organisations also need to protect and update their computer systems.
Japan’s Financial Services Agency urged banks to move away from driving licences as the primary identity document for opening accounts.
The agency recommended chip-enabled documents, including passports and MyNumber cards, to strengthen identity verification.
More than 20 major companies disclosed cyber incidents in recent weeks, potentially exposing tens of millions of customer records.
JR East said about 1.67 million customer email addresses might have been compromised; incidents have also affected public institutions and businesses.
Experts warn AI could make attacks easier to prepare, but there is no clear evidence it caused the recent Japanese breaches.
