2025四川省赛-Java题目see反编译 jar 包，只有一个 index 路由提示 debug log，再看依赖，log4j2 版本为 2.14.1，这个版本是存在 CVE-2021-44228 漏洞的但是不知道哪里注入点，先运行 jar 包，不断 fuzz 发现 cookie 引发的报错记录到了日志中，所以这里构造 poc成功弹出计算机不过这个只能打一次，因为这个错误只会记录一次。snake

使用了大量携带正常数字签名（含国内数字签名）的文件进行木马传播、使用了多种反沙箱/反调试技术进行安全技术对坑、外联亚马逊的AWS S3存储桶下载并执行最新恶意载荷

毕业半年,陆陆续续也是跟着公司和团队经历了好几次线上线下攻防护网,有过被队伍大哥带飞过爽拿名次,也有全程没输出压力暴大的时刻,,当我还在外网敲敲打打信息收集,其他队伍已经拿1/0/nday 内网漫游,不同于SRC 细致的信息收集,我眼中的红队信息收集则更为宏观,在有效的时间内只能批量的寻找薄弱资产拿信息要么拿权限

如何防止模型滥用？如何避免隐私泄露和偏见传播？如何评估模型在安全性和可靠性上的表现？这些问题不仅关系到技术的可持续发展，更关乎社会的公平与安全。 为了更好的理解这些问题，对于大模型开展安全测评是至关重要的。

前言本文系统性地剖析了栈溢出漏洞及其衍生的初级ROP利用技术，从最基础的缓冲区溢出原理出发，逐步深入至返回导向编程（ROP）的各个层面。我们将通过实际案例展示如何通过精确计算偏移量覆盖返回地址实现控制流劫持，并在此基础上探索ret2text、ret2libc、ret2syscall、ret2csu以及栈迁移等核心技术。无论是32位还是64位环境，无论是动态链接还是静态编译，本文都将提供从理论分析到

题目考核点很宽泛，而且比较贴近实际，创新性也很高

为了防止忘掉，特意花时间重新写了一遍

前言现在绝大多数免杀思路为混淆shellcode，这个只要多套几层加密就可以绕过静态检测，难的是绕过动态检测，因为它会对你的行为进行分析，但是动态检测大多情况在沙箱或者虚拟机调试分析，那如果我们可以识别出这些运行环境，避免在这些沙箱上面运行，是不是就绕过了动态检测了呢？最后再执行shellcode，免杀不就完成了吗？本文系统梳理了当前主流沙箱平台的共性特征，并围绕六大关键维度展开深入实践：用户名与
