Ok, problem seems to be solved.
This is the new AI powered whack a mole that we'll be doing with exploits
Security update and coordinated upgrade:
The core team has identified a vulnerability in public Gateway Addresses that affects asset issuance, including fUSD.
Transaction privacy is unaffected, and no spend keys or wallets are compromised.
We will coordinate a network upgrade asap. It requires majority consensus to activate, so we ask node operators, pools, and exchanges to be ready to update. No action is needed from ordinary users beyond upgrading when the release is published.
A full technical write-up will follow after the upgrade is in place.
