What this means for you

Based on the types of data in this breach, in order of importance.

  • Check bank and card activity

    Bank or payment details were among the data. Look for debits you do not recognise, ask your bank whether to replace a card or account, and ignore calls or texts that claim to be your bank and ask for codes.

  • Watch for smishing and SIM-swap attempts

    A leaked phone number lets criminals send convincing text messages and try to take over the number. Do not tap links in unexpected SMS, set a PIN with your mobile carrier and prefer an authenticator app to SMS codes.

  • Expect phishing letters and delivery scams

    A physical address makes impersonation more believable and enables fake letters and parcel notices. Treat unexpected post or delivery messages asking for money or details with suspicion, and check anything official on the sender’s own website.

  • Expect more targeted phishing

    Your email address ties you to this service, which is enough for a believable message such as a fake account warning. Check the sender and the web address before you sign in, and go to the site directly instead of using links in email.

  • Limit what attackers can personalise

    Names, employers, job titles and social profiles make impersonation and spear-phishing easier. Check what your public profiles reveal, and be careful with unexpected requests that use your real name or workplace.
