What happened?

Around April 2016, an outside party obtained a large amount of data from KnownCircle, a marketing automation firm for agents and service providers that has since shut down. The data concerned the insurance and real estate industries and seems to have been used for marketing, with logs of sent emails and gift card tracking. A few staff passwords were included, stored as bcrypt hashes.

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

  • Your passwordpasswords

    The password for this account was in the data, either as written or in a stored form that can often be reversed when the password is short or common. Anyone with the list can try it on your email, bank and shopping accounts.

  • 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 phone numberphone numbers

    Expect texts and calls that use your real details to sound genuine. A phone number is also what a fraudster needs to try to move your service to their own SIM card.

  • Messages you wroteemail messages

    Private messages can hold personal details, and their exposure can be used to pressure or embarrass you.

  • 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 detailsgenders and names

    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. Change the password, and every reuse of it

  • Change your KnownCircle password if the account still exists. Then change the same password on every other account where you used it, starting with your email.
  • Use a different password for each account. A password manager makes that practical: it creates long passwords and remembers them for you.
  • Turn on a second sign-in step, such as a code from an app or a security key, for your email, bank and social accounts. Your email comes first, because every password reset goes to it.

2. 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.

3. 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).

4. Protect your phone number

  • Ask your mobile carrier to put a PIN or passcode on your account, and ask whether it offers a lock on SIM changes and number transfers.
  • Treat texts about deliveries, accounts or payments with care. Do not tap the link: contact the company on a number you already have.

5. Assume your messages can be read

  • Think about what you wrote on KnownCircle and who it names. Warn anyone whose details you shared.
  • If someone threatens to publish what you wrote unless you pay, do not pay. Keep the messages and report it to your local police.

6. 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.
