LLM Agent 走进生产环境后，安全工程师面对的最棘手问题不是"模型会不会被骗"，而是三类结构性失范——偷懒、越权、失忆。我们团队在自研数仓 Agent 平台的过程中，设计落地了一套框架层护栏架构，用确定性代码把危险路径在框架层物理封死。本文从我们自己的研发实践出发，论证为什么 prompt 构不成安全边界，并逐层拆解这套护栏方案：读写两侧 offload、HITL 门禁、上下文联动闭环。 我

面对日益成熟的恶意Skill检测引擎，攻击者如何利用“信息差”实现绕过？本文将我沉淀的绕过技术归纳为“三类九板斧”，从原理剖析到实战落地，完整记录了从零开始绕过Cisco、NVIDIA及国内Top安全厂商检测引擎的全过程。

基于太阿构建一个真实项目可用的静态分析工具

本文分析了 Windows 11 ExecutionContext.sys 驱动中存在的任意内核代码执行漏洞，攻击者可通过 NDIS KLoader 代理路径绕过 ACL 限制，利用任务队列机制中缺乏有效校验的回调指针实现 RIP 劫持。文章详细阐述了从用户态可达入口发现到构造 ROP 链完成本地提权。

AI 大模型语义缓存技术在WAF实时检测领域实践经验分享

本文记录了一次基于Linux的后门的分析过程。分析从投递器脚本入手，由投递器带出s、p、p2、mulu-agent-c 四个文件，文章分别对投递器和四个恶意文件进行详细分析。

本文记录 Hack The Box Monteverde 靶机的完整渗透过程。目标是一台 Windows Active Directory 域控，初始突破口来自 LDAP 匿名枚举与一次“密码即用户名”的弱口令猜测。通过 SABatchJobs 账户访问 SMB 共享，在 users$ 中发现 azure.xml 明文凭据，成功登录 mhope 用户并拿下 User Shell。随后发现目标部署了

本文记录 Hack The Box Timelapse 靶机的完整渗透过程。目标是一台 Windows Active Directory 域控，初始信息来自 SMB 匿名可访问的 Shares 共享。通过下载并破解 winrm_backup.zip 与其中的 legacyy_dev_auth.pfx 证书文件，成功获取客户端证书与私钥，并利用 WinRM over HTTPS 的证书认证拿到初始

本文记录 Hack The Box Zero 靶机的完整渗透过程。目标仅开放 SSH 与 HTTP 服务，初始突破口来自一个支持 SFTP 上传的静态主页系统。通过注册获取 SFTP 凭据后，利用可覆盖的 .htaccess 配置 Apache ErrorDocument 404，实现任意文件读取，并从 Web 源码中泄露数据库凭据，成功拿到普通用户 Shell。随后通过 pspy 捕获 root

暴雪宣布了 FPS 版《星际争霸》，游戏仍然处于早期开发阶段，目标发售时间是在 2030 年。暴雪称，新作是一款开放世界、剧情驱动的科幻射击游戏，故事背景设定在《星际争霸 II》事件发生后数十年，是《星际争霸》宇宙中的一款全新作品。RTS 版《星际争霸》于 1998 年发布，2015 年发布了《星际争霸II》三部曲中的第三部《虚空之遗》，时隔 11 年之后宣布的正统续作不再属于 RTS。FPS 版《星际争霸》游戏设定在 Koprulu 星区（Koprulu Sector），时间位于《虚空之遗》剧情结束后的 70 年。
