You usually don’t get a warning when your information is stolen. No loud noise. No big red screen. Sometimes you learn about it months later because a company sends you an email saying your account was part of a problem.
Start With the Breach Itself
If a company you use says there was a problem take it seriously. Look at the companys website or call the support team directly instead of trusting a message that came into your email. People who try to trick you love breach news because people’re already worried.
Look for an explanation of what happened. The important question is what information was shared. Your email address is one thing. A stolen password is more serious especially if you used it somewhere else.
Check Your Email Address
One helpful step is checking whether your email address shows up in a known list of breaches like Have I Been Pawned. Type the address into the website yourself. Don’t click a link that says it will check for you.
Don’t get scared if your address shows up. A breach record doesn’t mean someone is in your accounts now. It means your information was found in data connected to a known problem.
Watch for the Little Signs
• A login from a place you don’t recognize one that keeps happening needs more attention.
• A password suddenly not working. If you didn’t change it that’s a sign to be careful.
• Messages from your account can be harmless. A request to reset your password that you didn’t ask for is worth checking before doing anything else.
• Your bank or card activity looks strange. Don’t wait around hoping it will make sense.
What to Do If You Were Affected
If a breach shared your password change it away on the service that was affected. If you used that password else change those accounts too.. Make each new password different.
Enable two-factor authentication where it’s available. It creates another step if someone has your password, which’s exactly what you want after a problem.
So How Sure Can You Be?
You can’t always be certain. Some problems aren’t found away and stolen information can sit around without causing any obvious issues.
You can get pretty close, to knowing if you are involved by looking at breach announcements watching for strange account activity and treating passwords used in multiple places as a problem that needs fixing now.
