After getting hacked, I took a security course on Bilibili and used Claude to walk through each configuration step for self-check.

I recently fell victim to an attack as well. The Japanese device had its port 443 blocked, but the IP remained unaffected. That night, I immediately added redundancy: backup subscriptions, server snapshots, and anti-traffic identification measures were all deployed. Incidentally, I also took a course on blockchain personal security architecture inspired by Shen Yu's presentation.

Summary

Review the results before exploring further

I got hacked two days ago; the device in Japan had its port 443 blocked, but the IP remained safe. That night, I immediately added redundancy: a backup subscription, server snapshots, and anti-traffic detection measures. I also went back to watch Shen Yu's presentation on on-chain personal security architecture from last year. Even after watching it in 2024, many concepts still didn't stick. When I tried to practice hands-on, everything felt overwhelming, and I couldn't continue. For example, after the talk, I attempted Apple's Advanced Data Protection but got stuck at a step because of device theft protection—the phone required waiting an hour, which seemed too troublesome, so I stopped. This time, I imported the presentation's documents and video into Claude to self-check, and most configurations are now in place.
