WhatsApp Scam Warning Sender

Free tool. Runs in your own browser.

Your WhatsApp sent a scam link to everyone. Warn them all in 5 minutes.

Someone linked their device to your account and messaged your contacts. This free tool finds every chat it was sent to and sends each one a warning.

Get the tool by email

We email it because you're probably on your phone right now, and this runs on a computer.

We use your email to send you this one file. Nothing else.

Do this on your phone first

About 60 seconds. This locks the scammer out. Do it before anything else.

  1. Remove devices you don't recognise

    In WhatsApp, go to Settings › Linked devices and log out of every device that isn't yours.

  2. Turn on two-step verification

    Go to Settings › Account › Two-step verification, turn it on and set a PIN.

  3. Check the email address and phone number on your account

    Go to Settings › Account and check both Email address and Change number. Make sure the email address and the phone number on the account are still yours.

How the scam works

Worth understanding, so you can explain it to the people you just warned.

  1. A friend's account is taken over. From that account you get a message asking you to vote for a child in a contest.
  2. It reads like a small favour, because it came from someone you know.
  3. The voting site asks you to enter a code that WhatsApp just sent you.
  4. That code is not a voting code. It links the scammer's device to your WhatsApp account.
  5. With your account linked, they send the same message to all of your contacts and groups, and it starts again.

need a small favor, Nora, a friend's kid, is in a contest where the top prize is tuition money. Your vote would mean a lot! Thanks!

Nothing was hacked and no password was broken. It works because the message arrived from a real person your contacts trust. That is also why warning them from your own account works so well.

Questions

Is this safe? What can it see?

It runs inside your own browser, on the WhatsApp Web page you are already signed in to. There is no account, no sign up and no server of ours. Your messages and contacts never leave your computer. We never see them.

It only reads your recent chats to find the scam message, and only sends the warning text you approve, to the chats you tick.

It found nothing.

Scammers often delete the sent messages from your side, so there is nothing left to match. Open one of your chats manually and look for the message yourself.

If it is there and the tool missed it, the search text is editable. Copy the wording from the message into the search box and run it again. If you're stuck, contact us.

Will WhatsApp restrict my account?

Be aware of the risk before you run it. This is an unofficial tool that automates sending. WhatsApp does not endorse automation and we cannot promise how they will treat it.

The slow send rate, one message every 2 to 4 seconds, is there to reduce that risk. You can also send to fewer chats, or stop at any time.

Why isn't it on the Chrome Web Store?

It was released fast as an emergency tool, and store review takes time people in this situation do not have. Remove it once you're done.

How do I remove it?

Open chrome://extensions, find WhatsApp Scam Warning Sender, and click Remove. You can also delete the unzipped folder.
