知名Python库litellm在PyPI平台被植入恶意代码，构成供应链攻击。受影响版本为1.82.8，内含恶意文件litellm_init.pth，会在Python进程启动时自动执行，无需主动调用。攻击影响范围广泛，用户安装该版本即触发后门。
谷歌AI编程工具Antigravity上线24小时内曝出严重漏洞，研究员通过修改配置可植入后门，执行恶意代码窃取数据或发动勒索攻击，影响Windows和Mac系统，仅需诱骗用户运行即可得手。
最新研究显示，ChatGPT等大语言模型易受数据中毒攻击，仅需约250份污染文件即可植入后门，改变模型回应，暴露AI安全脆弱性，引发对现有防护措施的反思。
Anthropic联合英国AI安全研究所等机构研究发现，大型语言模型易受数据中毒攻击，仅需250份投毒文件即可植入后门。测试显示，攻击效果与模型规模（6亿至130亿参数）无关，凸显AI安全漏洞的普遍性。
