How to Tell If Your Online Accounts Have Been Hacked

“If you think technology can solve your security problems, then you don’t understand the problems and you don’t understand the technology.” — Bruce Schneier

The internet is an amazing place, but let’s be real—it’s also full of threats. More and more hackers are targeting regular people, not just businesses or celebrities. Why? Because they want access to your bank accounts, your crypto, or even just your personal information to stalk or impersonate you.

Now, don’t panic—these attacks are still relatively rare. But knowing what to look for can help you catch a hack before it gets worse. Whether it’s your email, social media, chat apps, or banking platforms, here’s how you can tell if someone has gained unauthorized access to your accounts—and what you can do about it.

Signs That Your Account Has Been Hacked

Not sure if you’ve been hacked? Look out for these red flags:

• Unexpected Password Resets – If you receive an email or notification that your password was changed (and you didn’t do it), that’s a big warning sign.
• Strange Login Locations – Many platforms let you see where your account is logged in. If you see access from a country or city you’ve never been to, that’s a problem.
• Messages or Posts You Didn’t Send – If your social media or email account is sending messages you didn’t write, someone might be controlling it.
• Unfamiliar Transactions – If your bank or crypto wallet shows charges or withdrawals you don’t recognize, act immediately.
• Security Alerts from the Platform – Sometimes, services like Google, Facebook, or Apple will warn you if they notice suspicious activity. Take these alerts seriously.

If you notice any of these, don’t ignore them. The faster you act, the better you can minimize damage.

How to Check If Your Accounts Are Compromised (Platform by Platform)

Gmail / Google Accounts

Your Google account is probably the most important account you have—it’s linked to your email, Android phone, YouTube, and even some third-party services. Here’s how to check if it’s been hacked:

1. Go to Your Gmail Inbox. Scroll down to the bottom right and click on “Last account activity.”

3. Go to Google’s Security Checkup. Visit Google Security Checkup to review recent security events.

3. If You See a Device You Don’t Recognize, Remove It. Tap on the device and select “Remove from Account.”
