Signs of a hacked account and what to do
Hopefully you never have to worry about someone else accessing your account without your permission, but you can never be too safe. Here's how to recognize when someone else has signed in to your account, and the steps to regain control.
Signs your account has been hacked
- Your account information has changed without your knowledge.
- There are logins from locations you don't recognize on your recent activity page.
- You aren't receiving expected emails.
- Your Yahoo Mail account is sending spam.
What to do now
Receiving spam is one thing. Getting reports of spam coming from your account is another. If your account's been hacked to send spam, you can fix it! The fastest way to stop your account from sending spam is to secure your account by creating a new, strong password or enabling Account Key.
Forged messages are emails that appear to be sent from your email address, but they're actually sent from an entirely different email account. If your Yahoo Mail is secure, but people are still getting spam that looks like it comes from your address, it's probably a forged, or "spoofed," email.
- View the full header of the email in question.
- From the last Received line of the full header, take note of the originating IP address.
- This corresponds with the sender's Internet Service Provider (ISP).
- Conduct an IP lookup through a site like WhoIs.net to determine which ISP provides the sender with Internet access.
- Contact the sender's ISP to request that appropriate action be taken.
- Delete email contacts that you don't recognize.
- Delete linked Mail accounts that you don't recognize or control.
- Change your password on any linked accounts that you control.
- Make sure your vacation response is turned off.
- See if someone else has been accessing your account.
