逆向分析 360 for linux 版本

360已经开始抢占linux市场， 于是推出了360 for linux版本。 楼主分析的是pc版本，android版本底层功能应该类似。安装360后， 你会发现即使是root也kill不掉start360进程，360使用的所有文件也删不掉。 原因是它加载了两个内核保护模块360safe.ko和immu.ko， 360safe.ko用来保护其进程不被杀掉， immu.ko保护其文件不被删除掉。

进程不被杀掉的主要原因是修改了其保护进程的signal处理函数， 对SIG_SEGV进行了忽略。
immu.ko同理， 把其保护文件的inode->flags设置为一个不存在的模式，vfs不认识，所以对其进行忽略。

用以下脚本可手工删除360进程和文件：

root@wzt-pc:/home/wzt# cat kill360.sh
#!/bin/bash

function kill_360mod()
{
echo -n "start remove 360 kernel mods..."
rmmod immu && rmmod rk360 && echo -e "\tsuccessful."
}

function kill_360procs()
{
declare -a pids
local pid

pids=`ps aux|grep start360|awk '{print $2}'`
for pid in ${pids[*]}
do
echo -n "start killing start360 proc..."
kill -9 $pid >/dev/null 2>&1
echo -e "\tsuccessful."
done
}

function remove_360file()
{
rm -fr /etc/360safe
rm -f /usr/bin/start360
rm -fr /opt/360safeforlinux
rm -f /usr/share/applications/start360.desktop
}

kill_360mod
kill_360procs
remove_360file

请问楼主Linux Platform用什么工具逆的哇？
retme

@zjgood ...用IDA不是一样的么
zjgood
2015-02-06 16:06:14 +08:00
@retme 呃，IDA有linux版？静态调试器可以跨平台直接调试哇？

360的linux版看来没弄反逆向
retme
2015-02-06 16:29:20 +08:00
@zjgood IDA有linux版本，但是你在windows上一样可以使用IDA对linux模块进行静态反汇编阿
retme
2015-02-06 16:29:56 +08:00
@andyhenry 360 windows的版本，绝大部分模块也没有
andyhenry
2015-02-06 16:33:18 +08:00
@retme 我说知乎上怎么有这么多360的“内部分析”。。。看来360得好好找马化腾取取经了
retme
2015-02-06 17:00:32 +08:00
@andyhenry 额 其实是腾讯游戏当然反调试需求强，安全软件则更追求稳定性

其实被逆向了也没啥，有人逆向说明他们的技术还值得去逆向咯～
zjgood
2015-02-06 17:42:54 +08:00
@retme 很low的用ollydbg的动态调试思维在思考你们怎么逆向的。。。忘了还有IDA静态调试这货
