有一种欺诈手法专门针对您产品上的一个东西：发送验证码的表单。没有入侵，没有窃取，也不需要账号。机器人只是向您的表单请求验证码——成千上万条——发往付费高价号码，运营这些号码的人从中获利。您的表单按照设计正常运作，而账单由您买单。在本视频中，我们演示整个攻击流程，然后介绍 Bird 默认开启的两种防御机制。

Hey, and welcome back to another video. Today we're going to be talking about SMS pumping. A bit more serious topic, but one that I do want to make sure that you're aware of of its existence. And don't worry, these are rare situations, but in the event that they do happen, we want to make sure that you understand exactly what we do and what you can do to make sure that this doesn't harm your business. When you've got SMS verification set up, you allow your customers to trigger a verification SMS whenever they sign up or need to go through a registration process. Now, in the event that you've been targeted by SMS pumping, malicious parties will trigger bots on your sign up flows, triggering multiple SMS straight from your platform.
This will quickly be draining your balance, especially cuz they're usually sending to premium rate numbers in premium rate countries. They do this because they actually own some of these premium rate numbers, meaning that every message that gets delivered to these numbers gives a small payout back to the users that are actually triggering these bots.
Now, in order to prevent this, there's several things that you can do to keep yourself safe. Firstly, you can set a country layer, ensuring that you only send messages to countries that you know your customers are in. This prevents any countries outside of your reach to ever be triggered whenever you the user tries to sign up.
Additionally, we have Bird Verify. With Bird Verify, you hand the entire verification process over to Bird with additional abuse controls that come with it. One of which is automated retry delays, basically ensuring that a cool down has happened per recipient, making sure that a number can never be triggered multiple times.
Now, I hope this was a bit helpful. I don't want to scare you off, but it's important that you know what's going on. Regardless of everything, as always, happy sending.
