The internet is a dangerous place for data. On Friday (Nov. 30), hotel chain Marriott disclosed that hackers stole personal information from 500 million guests.

Sadly, the Marriott hack only managed to tie for the second largest data heist ever uncovered. As this list of history’s biggest hacks illustrates, no matter what you’re doing online—booking a hotel, looking for love, shopping, or checking your credit score—every time you put your information on the internet, you risk it going up for sale on the dark web.
