What happened
DAppSocial's lockTokens() function lacked validation that tokens were actually transferred, allowing an attacker to call deposit and create_deposit_record without sending funds. The attacker deployed a helper contract, deposited 2 USDT, set lock duration to 0, and withdrew without depositing tokens, exploiting the broken balance check.
