Step Finance Suffers $40 Million DeFi Breach on Solana Blockchain Step Finance, a decentralized finance (DeFi) platform operating on the Solana blockchain, disclosed a major security breach on January 31, resulting in the theft of approximately $40 million in digital assets. The attack stemmed from the compromise of devices belonging to the company’s executive team, granting unauthorized access to multiple treasury wallets. The exploit leveraged a "well-known attack vector," though Step Finance has not released specific details about the method or the perpetrators. Initial estimates from blockchain analytics firm CertiK suggested losses of $28.9 million (261,854 SOL), but the company’s internal investigation later confirmed the total at around $40 million. Through coordination with partners and Token22 protections, Step Finance recovered roughly $3.7 million in Remora assets and $1 million in other positions. Some platform operations were temporarily suspended to bolster security. The incident underscores ongoing security vulnerabilities in the DeFi sector, where high-value breaches remain frequent. In January alone, crypto-theft attacks accounted for over $398 million in losses industry-wide.
