What was exposed, and what does it mean for me?
- 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 detailsIP addresses (where you connected from) 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. 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.
2. 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.
