What happened
The DeFi pledge and liquidity strategy platform xToken was attacked, and the xBNTaBancor pool and the xSNXaBalancer pool were immediately exhausted, causing nearly $25 million in losses. The SlowMist security team analyzed that the two modules that were hacked this time were the xBNTa contract and the xSNXa contract in xToken. The two contracts were subjected to a "counterfeit currency" attack and an oracle manipulation attack.
