If you're an Atomic Wallet user, send them out to another wallet ASAP.
Until now, Atomic wallet doesn't state how users wallet is compromised (i checked few their website and few of their social media). So IMO it would be better if Atomic wallet move their coins/token by importing recovery words to other wallet rather than opening their Atomic wallet application.
Sad day for Atomic Wallet users, It's (another) stark reminder. Not your keys, not your coins.
Atomic wallet is a non-custodial wallet and gives you the private keys. The problem with Atomic wallet is that it's close source and there is no way to know how the keys have been generated and whether the user is the only who has access to the keys or not.
On top of that, Atomic wallet is owned is owned by Binance which historically has few questionable behavior. So i expect they'll be evasive/remain mostly silence about this incident.
