Don't let that happen.
Use Gatekeeper, the open-source tool that verifies every withdrawal you make is one that you want to make.
How does it work?
Register your KoinKeep (or cold wallet of your choice) with Gatekeeper. Every xpub and derivation path associated with any device in your storage arrangement must be registered.
Create a receiving address and pass that to Gatekeeper's client. Gatekeeper can find the script format from the address, making this step absolutely painless for you.
Send a small amount of your Bitcoin to that receiving address and then withdraw it. It's pivotal that you make sure all devices are offline and stay offline as you send and withdraw.
Pass the second transaction to Gatekeeper. Gatekeeper will then display the vital stats you need to make sure your Bitcoin is safe, including the transaction amount, the deposit address, the change processed back, and any warnings you need to see. That's right - Gatekeeper notices when a transaction is suspicious.
If you can verify the amount withdrawn and the destination addresses, you're good to publish. If not, Gatekeeper's just saved your wallet from theft or worse.
