An anonymous hacker claimed responsibility for a Danish CPR register breach affecting 8.8 million citizens, stating the attack succeeded because a former employee's password was simply '123456'. The hacker expressed shock at the inadequate security and has no plans to sell or leak the data, while the Danish government acknowledged the security failures and initiated a system review.
Apple and Google offer built-in tools to detect compromised passwords on iPhones and Android devices. Both services automatically monitor saved passwords against known data leaks and flag weak or reused credentials, allowing users to update them before they're exploited.
