Can someone teach me what the hack this address is for?

Attaching the link address (Polygon):
0x9bf475e0654ec615b473599c9d39ddd87b01e894

It is MATIC network, and I am sure my metamask is not hacked. However, while I was sleeping (double checked for sure) my WETH was involved in that transaction and now showing the balance of 0 on my wallet. I tried breaking things down, but there is a limitation so I need your help. Thanks.
