I haven't updated my iPhone 6s in over four years, and I'm starting to worry that it might be hacked. I received a message indicating that there are attacks targeting outdated iOS software, but I'm not sure what to do about it. Can anyone advise me on the steps I should take to secure my phone and whether I'm overreacting?

The alert you saw probably isn't related to the book you downloaded from that site. Apple sends out those warnings to warn users about the risks of outdated iOS versions. I received a similar message just a few hours ago! So don't stress too much about it—just update your phone and you should be fine.
It's likely that Apple's update alert isn't confirming anything seriously harmful, but you should definitely take it as a prompt to update your phone. Clearing your browsing history could be a good first step too. It sounds like you might be overthinking it, but updating is a smart move regardless.

Thanks for clarifying! I was really worried it had something to do with that download. I'll make sure to update my iPhone soon.
