# Malicious Macro Generator Utility

Simple utility design to generate obfuscated macro that also include a AV / Sandboxes escape mechanism.

# Requirement

```

Python 2.7

```

# Usage

```

MMG.Malicious Macro Generator v2.0 - RingZer0 Team

Author: Mr.Un1k0d3r [email protected]

Usage: MMG.py [config] [output] (optional parameters)

        [config]                                Config file that contain generator information

        [output]                                Output filename for the macro

        -l      --list                          List of all available payloads and evasion techniques

        -s      --split_strings                 Randomly split strings at parts

        -x      --strings_to_hex                Encode strings to hex

python MMG.py configs/generic-cmd.json malicious.vba

```

# Config file

Example of a project config file.

```

{

	"description": "Generic command exec payload\nEvasion technique set to domain check",

	"template": "templates/payloads/generic-cmd-evasion-template.vba",

	"varcount": 150,

	"encodingoffset": 4,

	"chunksize": 200,

	"encodedvars": 	{

				"DOMAIN":"RINGZER0"

			},

	"vars": 	[],

	"evasion": 	["encoder", "domain"],

	"payload": "cmd.exe /c whoami"

}

```

# Evasion techniques

###### Domain check

The macro is fetching the USERDOMAIN environment variable and compare the value with a predefined one. If they match the final payload is executed.

###### Disk check

The macro is looking for the total disk space. VMs and test machines use small disk most of the time. 

###### Memory check

The macro is looking for the total memory size. Vms and test machines use less resources.

###### Uptime check

The macro is looking for the system uptime. Sandboxes will return a short uptime.

###### Process check

The macro is checking if a specific process is running (example outlook.exe)

###### Obfuscation 

The python script will also generate obfuscated code to avoid heuristic detection

###### More to come
