What was exposed, and what does it mean for me?

  • Identity detailshome addresses

    A home address makes a scam letter or a fake delivery notice look genuine. With a date of birth from another breach, it is most of what a lender asks for when someone opens credit in your name.

  • Your email addressemail addresses

    Expect messages that look like they come from this service or another one you use, written to get you to click a link or sign in on a fake page.

  • Other detailsemployers, job titles, names and support tickets

    On their own these carry less risk, but they make a scam message sound more personal.

What should I do now?

In this order, for what this breach exposed.

1. In the US: freeze your credit at all three bureaus

  • Place a credit freeze with Equifax, Experian and TransUnion. It is free to place and to lift, and it does not affect your credit score.
  • If you would rather not freeze, a fraud alert lasts one year. You ask one bureau and it tells the other two.
  • If someone uses your details, report it at IdentityTheft.gov to get a recovery plan.

2. In Canada: check your credit file and lock it

  • Get your credit report from Equifax Canada and TransUnion Canada. Both give it free online.
  • In Ontario, both bureaus must offer a security freeze free of charge, and each bureau is a separate request.
  • If you live in Quebec or Ontario, Equifax Canada will lock your credit report at no charge, online, by phone or by mail. Ask TransUnion Canada separately.
  • If your details are used to open an account, call your bank, report it to both bureaus, report it to your local police and get a file number, then report it to the Canadian Anti-Fraud Centre (1-888-495-8501).

3. Expect phishing

  • Be wary of messages that urge you to act fast, ask for personal details, or link to an address that is slightly off.
  • If a message might be genuine, do not use its links or phone numbers. Go to the site by typing its address yourself.
