The firm experienced two serious security incidents within months of each other in 2023: an insider sabotage case in which two disgruntled engineers tampered with trading code causing $1.4 million in losses, and an external hack in November 2023 where compromised API keys led to the theft of approximately $25–26 million. The November hack cascaded onto WOO X, an exchange Kronos incubated and served as primary liquidity provider, causing a temporary trading halt and liquidations for 227 users.","timeline":[{"date":"2018-06-01","event":"Kronos Research founded in Taipei, Taiwan by Mark Pimentel and Jack Tan.","source":""},{"date":"2019-01-01","event":"Kronos Research incubates WOO Network (later WOO X) and becomes its primary backstop liquidity provider.","source":""},{"date":"2023-08-27","event":"Two disgruntled former engineers convicted in Taipei court for tampering with Kronos Research trading algorithms over unpaid bonuses, causing $1.4 million in losses.","source":""},{"date":"2023-11-18","event":"Unauthorized party accesses Kronos Research exchange API keys and begins draining approximately $25–26 million across multiple exchanges.
