There was a bug in the GUI when creating a new wallet and you typed something into the "Seed Hash" field and deleted it again, it would create a wallet with a seed value of all zeros. So if you have such a wallet, which has the address mmx1m00s7j9w965q53ehkhht64fpk7f8vpzjcucepejt3gq084qrtnqqdtplv0 consider it compromised, including any plots that you created with it. (I hope nobody did plot with it)
