php网站被挂木马修复方法总结,php挂木马总结

在linux中我们可以使用命令来搜查木马文件,到代码安装目录执行下面命令

代码如下 复制代码
find ./ -iname "*.php" | xargs grep -H -n "eval(base64_decode"

搜出来接近100条结果,这个结果列表很重要,木马都在里面,要一个一个文件打开验证是否是木马,如果是,马上删除掉

最后找到10个木马文件,存放在各种目录,都是php webshell,功能很齐全,用base64编码

如果你在windows中查找目录直接使用windows文件搜索就可以了,可以搜索eval或最近修改文件,然后如果是dedecms我们要查看最新dedecms漏洞呀然后修补。


下面给个php木马查找工具,直接放到你站点根目录

代码如下 复制代码
