Bankr, an AI-driven cryptocurrency trading assistant, has suffered a security breach, resulting in the compromise of 14 wallets and losses totaling $150,000. The attack prompted Bankr to temporarily halt operations while investigating the breach to prevent further damage. The company has pledged to reimburse affected users and advised them to cease using the compromised wallets immediately. The breach involved a social engineering exploit targeting the interaction between automated agents, specifically Grok and Bankrbot, allowing unauthorized transaction signing. This incident follows a similar exploit earlier this year, where a token launch was manipulated to siphon funds. The breach underscores the vulnerabilities in AI-powered trading systems and highlights the growing security challenges in the Web3 space, as 2026 continues to witness significant exploits.
