If you are using metamask, consider moving your funds to a more secure location until more information is known. There have been multiple reports of metamask wallets being drained. All information currently known suggests the victims were phished, but all known victims use metamask.

If you use Brave Browser it has built-in crypto wallet with support for a hardware wallet and supports Metamask protocols (can be used in replacement of Metamask).

If you are not using a hardware wallet, I highly recommend you get a Trezor or a Ledger from a reputable source.
