This roundup covers Polymarket's roughly hour-long suspension of international trading on Thursday after a third-party software vendor was compromised. Polymarket promised to reimburse affected users after reports that funds had been emptied from some wallets. A person familiar with the matter identified the vendor as DebugBear, a performance-monitoring and debugging platform. DebugBear acknowledged an ongoing security incident and urged customers to remove an embedded monitoring tool from their websites.
