No NFT photography!

Looks like we have a new kind of wallet asset theft: taking a picture of the balance screen. A scammer claiming to be an investor stole an entire collection of NFTs worth about $4 million from a Webaverse founder. 
 
The fraudster explained that he needed to see the proof of NFTs before signing a partnership agreement.
 
The victim insists that he only showed the scammer the Trust Wallet balance interface. He revealed no seed phrases or private keys. The thief took some pictures of the screen and went out for a smoke. A few minutes later the funds were drained from the wallet, and the potential partner had never returned.
 
The weird story is confirmed by Etherscan. 
 
The odd thing is that the theft happened on Nov. 26, but was reported only now. Did the victim hope to wake up one fine day and realize that everything was just a dream?
