Leoric

Leoric 是一个 Android 上的黑科技保活方法的 PoC,它可以对抗在任意 Android 版本上的 force-stop 杀进程。

Leoric 是 Dota 中的英雄"骷髅王",本项目名取自骷髅王的大招「重生」。

Leoric

重现方法

虽然理论上这个方法可以支持任意的 Android 版本,但本 PoC 在 Android 9.0 及 Android 10 上测试过。具体使用方式参见 demo 项目。

实现原理

应对方法

下面是一种简单的方法杀死 Leoric:

ps -A | grep `ps -A | grep me.weishu.leoric | awk '{print $1}' | head -1` | awk '{print $2}' | xargs kill -19 && am force-stop me.weishu.leoric

对于系统有两种思路可以选择:

  1. 加入在 force-stop 期间不允许启动新的进程的逻辑
  2. 修改 force-stop 的杀进程逻辑为:预先收集好所有进程再进行 kill(如有必要还可以先发送 SIGSTOP)

郑重声明

本项目仅做学习研究使用,出现任何问题概不负责。另外,本 PoC 离实际投入使用还有很长的路要走,请不要妄想直接接入代码就能得到永生。

之所以公开代码,是为了推动厂商对系统做出改进,提供应对之法;请不要滥用!!
