大佬,这个后门给目标种上后有啥用吗?或者说我如何使用这个后门
添加定时任务很容易被发现,所以产生删除定时任务功能想法
尝试删除第172-214行代码 和CRONTAB_CODE1 CRONTAB_CODE2变量
然后自定义变量
#define MAGIC_STRING "tomcat" // hide process one
#define MAGIC_DEAMON "tomcat" // hide process two
#define CONFIG_FILE "xld.so.preload" // hide self
#define LIB_FILE "xliblinux64.so" // hide self
#define MAGIC_PORT 8080 // hide port
加载后使用ps -ef命令出现报错情况
系统:CentOS Linux 7
# ps -ef
Segmentation fault
注:所有操作在vshell命令执行控制台下执行,并且如果出现上述情况,vshell命令执行控制台再也进不去了,需要在文件管理
里删除/etc/ld.so.preload中加载的so才能正常进入
按照README卸载后门后,定时任务无法卸载
