A galaxy-sized entity, maybe? The only known way to find a private key from a public key is brute force. That's way beyond the abilities of a state, unless they've made a massive breakthrough in quantum computing.

- nullc 13y agoObpedantry: In theory rho allows you to recover private keys with work-factor 2^128 (times some small constant depending on how much storage you wish to use), which is significantly less than the 2^256 you might expect from "brute force". Still completely infeasible.
- teraflop 13y agoBut first you have to obtain the public key by finding a preimage of the SHA-256-hashed address. And SHA-256 (with the full number of rounds) currently has no known preimage attacks that are even marginally better than brute force.
