This doesn't appear to be true (in the sense that yes it is feasible to crack 4-word BIP pass phrases, but all wallets that I'm aware of use at least 6 words, which is estimated to take 11 years for a hypothetical ASIC cracker)

Perhaps you are meaning this attack where someone was able to brute-force 4 words from a 12 words phrase. It matches your $350 cost, but of course is dramatically different to "cracking BIP39": https://medium.com/@johncantrell97/how-i-checked-over-1-trillion-mnemonics-in-30-hours-to-win-a-bitcoin-635fe051a752 https://medium.com/@johncantrell97/how-i-checked-over-1-tril...

- nl 4y agoThat's an extremely different proposition. Pretty sure the NSA isn't into stealing bitcoins.
- pffft8888 4y agoThat's 66 bits of entropy. With a quantum computer having 66 logical (error corrected) qubits, the pass phrase can be cracked in under a day. That's not too far off, maybe a few years before one is commercially available.
