# swap\_digger

swap\_digger is a bash script used to automate Linux swap analysis for
post-exploitation or forensics purpose. It automates swap extraction and
searches for Linux user credentials, Web form credentials, Web form emails,
HTTP basic authentication, WiFi SSID and keys, etc.

![Sample run](/assets/swap_digger.png?raw=true "Sample run")

## Download and run the tool

### On your machine

Use the following commands to download and run the script on your machine:

```bash
git clone https://github.com/sevagas/swap_digger.git
cd swap_digger
chmod +x swap_digger.sh
sudo ./swap_digger.sh -vx
```

![Extended run](/assets/swap_digger_extended.png?raw=true "Extended run")

### On a mounted hard drive

To use swap\_digger on a mounted hard drive, do the following:

First, download the script using the following commands:
```bash
git clone https://github.com/sevagas/swap_digger.git
cd swap_digger
chmod +x swap_digger.sh
```

Then, find the target swap file/partition with:
```bash
sudo ./swap_digger.sh -S
```

Finally, analyze the target by running:
```bash
sudo ./swap_digger.sh -vx -r path/to/mounted/target/root/fs -s path/to/target/swap/device
```

### On a third party machine

Use the following commands to download and run the script on a third party machine (useful for pentests and CTFs):

```bash
wget https://raw.githubusercontent.com/sevagas/swap_digger/master/swap_digger.sh
chmod +x swap_digger.sh
sudo ./swap_digger.sh -vx -c
```

Note: Use the `-c` option to automatically remove the directory created by swap\_digger (`/tmp/swap_dig`).

## Simple run

If you only need to recover clear text Linux user passwords, simply run:
```bash
sudo ./swap_digger.sh
```

## Available options

All options:
```
./swap_digger.sh [ OPTIONS ]
Options :
-x, --extended Run Extended tests on the target swap to retrieve other interesting data
(web passwords, emails, wifi creds, most accessed urls, etc)
-g, --guessing Try to guess potential passwords based on observations and stats
Warning: This option is not reliable, it may dig more passwords as well as hundreds false positives.
-h, --help Display this help.
-v, --verbose Verbose mode.
-l, --log Log all outputs in a log file (protected inside the generated working directory).
-c, --clean Automatically erase the generated working directory at end of script (will also remove log file)
-r PATH, --root-path=PATH Location of the target file-system root (default value is /)
Change this value for forensic analysis when target is a mounted file system.
This option has to be used along the -s option to indicate path to swap device.
-s PATH, --swap-path=PATH Location of swap device or swap dump to analyse
Use this option for forensic/remote analysis of a swap dump or a mounted external swap partition.
This option should be used with the -r option where at least //etc/shadow exists.
-S, --swap-search Search for all available swap devices (use for forensics).
```
