3、技术原理
1. 安全开发技术整合
第13章技术整合架构:
┌─────────────────────────────────────────────────────────┐
│ 综合安全工具 │
├─────────────────────────────────────────────────────────┤
│ 持久化模块 信息收集模块 功能执行模块 │
│ ├─────────┤ ├────────────┤ ├────────────┤ │
│ │ 自启动 │ │ 键盘记录 │ │ 屏幕截屏 │ │
│ │ 自删除 │ │ 屏幕截屏 │ │ 令牌提权 │ │
│ │ 资源释放 │ │ 系统信息 │ │ 文件操作 │ │
│ └─────────┘ └────────────┘ └────────────┘ │
├─────────────────────────────────────────────────────────┤
│ 核心控制模块 │
│ 配置管理 日志记录 通信模块 错误处理 │
└─────────────────────────────────────────────────────────┘
技术协同关系:
自启动 → 资源释放 → 功能模块初始化 → 持久化保障
2. 实际应用场景
应用场景示例:
1. 远程管理工具
- 键盘记录收集用户输入
- 屏幕截屏监控操作
- 令牌提权获取系统权限
- 自启动确保持续运行
2. 安全审计工具
- 收集系统配置信息
- 监控敏感操作行为
- 生成安全报告
3. 渗透测试辅助
- 隐蔽信息收集
- 权限提升验证
- 痕迹清理
