POLYMARKET'S $7M “HOME ALONE ATTACK”

Summary from the TLDR Crypto newsletter

A $7m prediction market on Polymarket was manipulated in an attack during a UMA oracle dispute. Attackers exploited unmonitored periods and timed their moves with UMA's voting deadlines to falsely claim that a mineral deal between the US and Ukraine had been agreed upon since February. The tactic resulted in an unwarranted market resolution that netted around $200k for the conspirators and triggered cascading issues across related markets.
