## :hear_no_evil: kernel mode rootkits
- https://github.com/f0rb1dd3n/Reptile
- https://github.com/f0rb1dd3n/Reptile :point_right: [details](details/reptile.md)
Reptile is a LKM rootkit written for evil purposes that runs on Linux kernel 2.6.x/3.x/4.x
| Feature | Description | Implementation Details |
| --- | --- | --- |
| Environment | 2.6.x/3.x/4.x (x86) | `sys_call_table` search method is x86-only |
| Persistency | /etc/modules or /etc/rc.modules | Boot-time module loading using OS-specific startup files. |
| Management interface | `kill(2)` | `sys_call_table[__NR_kill]` |
| Altering system (library) behaviour | Hooking of system calls | `sys_call_table` patching using `CR0/WP` |
| Hiding (tampering) of file contents | Filtering while reading | `sys_call_table[__NR_read]` |
| Hiding of files and directories | Filtering of directory entries | `sys_call_table[__NR_getdents]` `sys_call_table[__NR_getdents64]` |
| Hiding of processes and process trees | Filtering of `/proc` | Filtering PID-like numeric entries while listing `/proc`. Hidden tasks are marked using `task->flags \| 0x10000000`. Not able to hide all threads and children of hidden (parent) process. |
| Detection evasion | Hides own components | Hide files, unlinks module from `module_list`, alters contents of startup files while reading. |
