Safery allows people to either set up a new wallet or import an existing one. In both cases, the extension requests the user’s seed phrase. Once entered, this information is immediately processed and sent out in a way that is difficult to detect.

Socket explains in the blog post:
When a user creates or imports a wallet, Safery: Ethereum Wallet encodes the BIP-39 mnemonic into synthetic Sui style addresses, then sends 0.000001 SUI to those recipients using a hardcoded threat actor’s mnemonic.
