Wiener DOGE token exploited via flash loan attack. The deflationary token failed to exclude LP pairs from transfer fees, allowing an attacker to drain tokens from liquidity pools. The k-value was destroyed, and the attacker profited approximately 78 BNB.

The Wiener DOGE project was exploited maliciously, causing $30,000 in damages. Attackers exploited the inconsistency between WDODGE's charging mechanism and swap pools to launch the attack. The root cause of the incident is that the sender's LP pair is not excluded from the transfer fee through the tightened token contract. As a result, the attacker is able to drain the deflationary tokens in the LP pair, which in turn causes the pair price to become unbalanced.
