What was exposed, and what does it mean for me?
- Bank and money detailsaccount balances
Account numbers, balances and payment history let a scam call or email quote facts that only your bank should know.
- 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.
- 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 detailsnames
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. Tell your bank and watch the account
- Watch your statements for payments you did not make, and tell your bank about the breach.
- If someone calls quoting your account details, hang up and call the bank on the number you already have.
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. 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.
