On April 9, on-chain detective ZachXBT revealed that Bitcoin ATM operator Bitcoin Depot (BTM) reported a security incident in an 8-K filing submitted to the U.S. Securities and Exchange Commission (SEC), stating that approximately 50.9 BTC (around $3.6 million) was stolen on March 23. However, the investigation indicates that the actual incident may have occurred as early as March 20, meaning the company did not detect the funds were missing until about three days later. Through on-chain tracking, 19 highly credible related addresses were identified, involving a total of approximately 54.45 BTC (around $3.7 million), which exceeds the company's disclosed figures by about 3.55 BTC, potentially involving personal accounts of employees. The flow of funds shows that approximately 54 BTC ultimately transferred to the cryptocurrency exchange KuCoin. As of now, these involved addresses have not been flagged by mainstream compliance monitoring tools.
