Just hours ago, Solana is being attacked. As of this posting, the attack hasn't ended yet. So far, the stolen amount has already exceeded $6 million.
It is advised for users to start "unlinking browser-based Solana wallets from all internet sites, and moving funds to a new clean wallet." And this is urgent.
If you have cold wallets, it is better to transfer your coins and tokens there for the time being. It is found out that hot wallets such as Phantom, Slope, and Trust Wallet are already being drained of funds because of this current attack.
