What happened
Attackers exploited ORBToken’s receive() function (which auto-granted max allowance) and ORBCore’s whitelist tax exemption. The addPoolAndSell function lacked a reentrancy guard, enabling repeated tax-free sells. Combined with burnLP destroying large amounts of ORB in the LP and a subsequent sync() to manipulate reserves, the attacker extracted about $32,610.72.
