What was exposed
TaiLieu’s breach included 8 kinds of data. What each lets criminals do:
| Data | What it’s used for |
|---|---|
| Passwords | Criminals try leaked passwords on email, banking and shopping sites, because people reuse them. |
| Usernames | Half of a login. With a reused password, it opens other accounts. |
| Dates of birth | Used to prove who you are to banks and phone companies. |
| Names | Makes scam messages personal enough to believe. |
| Email addresses | Expect scam emails that name the company to look genuine. |
| Phone numbers | Expect scam texts and calls, and a higher risk of someone moving your number to their SIM. |
| Genders | Personal details that make scam messages more convincing. |
| Geographic locations | Roughly where you live. |
What to do
- Check whether you’re in it.Search your email address on Have I Been Pwned. It tells you which breaches it appears in, TaiLieu among them, without showing the data.
- Change your TaiLieu password.If the account still exists, sign in at TaiLieu (tailieu.vn) and change it.
- Change it anywhere you used the same one.Start with your email, then banking and shopping. Leaked passwords are tried on other sites automatically, within days.
- Use a password manager and two-step sign-in.A different password for every site means one breach can’t open the rest. Two-step sign-in stops a leaked password working on its own.
- Distrust messages that mention TaiLieu.Scammers use breach data to sound genuine. Don’t click links in emails or texts about the breach; go to the site yourself.
- Put a PIN on your phone account.Ask your mobile provider for a port-out PIN, so no one can move your number to their SIM.
