Polymarket Confirms Supply Chain Attack, $3 Million Stolen
Polymarket, a cryptocurrency-based prediction market, confirmed a supply chain attack. A breach of a third-party frontend vendor led to malicious JavaScript being injected into its website. Attackers tricked users into approving fraudulent transactions, resulting in approximately $3 million being stolen from fewer than 15 accounts. The backend systems remained unaffected.
