Launch Electrum, create a new wallet, "Import Bitcoin addresses or private keys", paste in the recovered key.

If you just paste the raw key, Electrum uses a legacy format, and none of the transactions show up for that private key. Adding the "p2wpkh:" prefix to the key makes the transactions show up, but I realized that well after someone else claimed it.

I don't know if this is an Electrum thing, if this is considered general knowledge now for those who regularly use BTC, or if it's a quirk of how BTC has evolved.

that was brutal! I knew you were holding out something. Oh man this is a brutal bug as well. That's an OS popup! That's gonna take me some time.

Actually even worse it's neither an OS level or dom level item custom chrome rendering layer.

That explains why the validator error looked entirely different when I tried to reproduce it locally -- I was wondering about that.

And yeah, it's a CTF, gotta hold onto issues until the flag redemption is back up.

bet you couldn't do it again. It's back up. Patch is a bit hacky but should work plus I blocked the signup page.

Real patch is a chromium update (like a week of work) so imma avoid that until needed.

Got it :)

Pasted the private key into the email address field on the Wufoo signup page, and the validator helpfully told me my "email" was invalid, with the whole key included.
