<p dir="auto">研究员 Vadim（前 NEAR 核心贡献者）指出，&quot;Grok 被黑&quot;的说法在技术上不准确——真正的问题在于 BankrBot 的架构设计：Grok 并不持有私钥，BankrBot 将 Grok 的文本输出直接当作金融授权指令执行，任何能让 Grok 输出特定格式命令的文本——无论是恶意用户注入还是摩斯电码——都能触发真实转账。攻击者还预先向目标钱包发送了一枚&quot;Bankr Club 会员 NFT&quot;以解锁转账权限，构成完整的两步攻击链。BankrBot 随即宣布已禁用 Grok 调用其命令的权限。这已是类似事件的第二次：2025 年 3 月，同类提示注入曾导致 BankrBot 基于 Grok 建议发行了包括 DRB 在内的多个代币，彼时限制措施显然未能持续。Vadim 总结称，“修复方案不是让 LLM 更聪明，而是不要建设将 LLM 文本作为转账授权的基础设施。”</p>
