In the apk, sometimes the root permission is required, such as updating system files such as system files through the apk, to avoid upgrading the firmware or directly accessing certain devices in the apk. The following method is used to obtain the root permission in apk, provided that the device has already been root.T

Linux Files cannot be modified and edited by the root user. Recently, a company's server was maliciously added some timer tasks to the crond configuration file "/var/spool/cron/root "., in this case, you only need to simply use the crontab-e command to remove the malicious task. However, after the modification, I found that no matter how hard I try to save it, di

They are all prepared for the system administrator and are some system management and configuration tools. This folder serves as/sbin in the standard Linux File System. My mobile phone has busybox in this directory. It must have been changed. It should have been added by the attacker.

files are concentrated in several directories. The code is as follows: Rm-f/var/log/httpd/access.log Will force deletion of/var/log/httpd/access.log this file -R is recursive down, no matter how many levels of directory, delete -F is simply forced to delete, without any hint of the meaning -I for interactive deletion.

care about the setUID permission. Therefore, after the setUID permission is added, the file permission should be composed of four digits. For example, if you add the setUID permission to the previous root file, it is 4755. The permission bit of the passwd file for password modification is 4755.You can use a small example to intuitively feel that the binary file corresponding to the common cat command does not have the setUID permission:You can use ca
