The 10 Most Common Signs of a Hacked Account

If you notice any of the following signs, your account might be compromised:

1. Unusual Login Activity: Logins from unfamiliar devices or locations you don’t recognize.
2. Password No Longer Works: You’re suddenly locked out of your own account with no control over it.
3. Messages Sent Without Your Control: Friends receive strange posts or private messages you didn’t send.
4. Email or Phone Number Changed: Recovery options were modified without your knowledge.
5. New Apps or Permissions Added: Unknown apps now have access to your account.
6. Profile Changes: Bio, profile picture, or name changed without your approval.
7. Unfamiliar Posts or Comments: Content appeared on your timeline or wall that you didn’t publish.
8. Unusual Follower or Friend Requests: Receiving requests from unknown users or sending unexpected ones yourself.
9. Multiple Failed Login Attempts: You're frequently logged out or asked to re-enter credentials.
10. Suspicious Ads or Recommendations: Seeing ads or suggestions that seem targeted to topics you’ve never searched for.

Types of Suspicious Activity and How Serious They Are

Not every sign means full compromise — but all deserve attention. Here's a comparison of different threats and what they mean:

Warning Sign	Severity Level	Recommended Action
Login from Unknown Device	Medium	Check session list and log out remotely
Password Not Working	High	Start recovery process immediately
Sent Messages or Posts You Didn't Write	High	Review sent messages and remove third-party apps
Changed Email or Phone Number	Critical	Use official recovery form as soon as possible
New App Permissions Added	Medium	Review and remove unknown app permissions

What to Do If You Spot These Signs

• Log into your account and check recent login activity
• Change your password using a trusted device

Even if you're unsure, it's always better to act early than wait until the situation worsens.
