BLOG: Yahoo data breach 'involves eight million UK user accounts'
Yahoo says a past data breach affected about eight million user accounts in the UK, meaning personal account details may have been exposed. People with Yahoo accounts should take this seriously because stolen account information can still be used for sign-in attempts, impersonation, or scams.
Who is at risk
Anyone in the UK who has a Yahoo account, especially those who still use the same password on Yahoo or on other accounts, is most at risk.
What to watch for
Watch for unexpected sign-in alerts, password reset messages you did not request, unfamiliar activity in your email account, or messages from someone pretending to be Yahoo.
What to do
Change your Yahoo password right away, make sure it is unique, update any other accounts using the same password, and turn on extra sign-in protection if available.
