Not sure if this exists yet, but as the "aspiring Chief Security Officer" at Nostr, I’m starting to track known and major attacks on and from the Nostr decentralized network. Inspired by @npub17u5d...t4tp's Known Bitcoin Attack list. Feel free to PR and contribute as I know there are many I'm missing.
