Interlace

A threading management application that allows controlled execution of multiple commands, over multiple targets.

Contributions

Contributions to this project are very welcome. If you're a newcomer to open source and would like some help in doing so, feel free to reach out to me on twitter (@codingo_) and I'll assist wherever I can.

Setup

Install using:

$ python3 setup.py install

Dependencies will then be installed and Interlace will be added to your path as interlace.

Usage

Argument	Description
-t	Specify a target or domain name either in comma format, CIDR notation, or as an individual host.
-tL	Specify a list of targets or domain names
-threads	Specify the maximum number of threads to run at any one time (DEFAULT:5)
-timeout	Specify a timeout value in seconds for any one thread (DEFAULT:600)
-c	Specify a single command to execute over each target or domain
-cL	Specify a list of commands to execute over each target or domain
-o	Specify an output folder variable that can be used in commands as _output_
-p	Specify a list of port variablse that can be used in commands as _port_. This can be a single port, a comma delimeted list, or use dash notation
-rp	Specify a real port variable that can be used in commands as _realport_
--no-cidr	If set then CIDR notation in a target file will not be automatically be expanded into individual hosts.
--no-color	If set then any foreground or background colours will be stripped out
--silent	If set then only important information will be displayed and banners and other information will be redacted.
-v	If set then verbose output will be displayed in the terminal

Further information regarding ports (-p)

| Example | Notation Type | |-------------------------| | 1-80 | Dash notation, perform a command for each port from 1-80 | | 80 | Single port | | 80,443 | Perform a command for both port 80, and port 443 |

Further information regarding targets (-t or -tL)

Both -t and -tL will be processed the same. You can pass targets the same as you would when using nmap. This can be using CIDR notation, dash notatin, or a comma dilimited list of targets. A single target list file can also use different notation types per line.

Variable Replacements

The following varaibles will be replaced in commands at runtime:

Variable	Replacement
_target_	Replaced with the expanded target list that the current thread is running against
_output_	Replaced with the output folder variable from interlace
_port_	Replaced with the expanded port variable from interlace
_realport_	Replaced with the real port variable from interlace

Usage Examples

Run Nikto Over Multiple Sites

Let's assume that you had a file targets.txt that had the following contents:

bugcrowd.com
hackerone.com

You could use interlace to run over any number of targets within this file using: bash

➜  /tmp interlace -tL ./targets.txt -threads 5 -c "nikto --host _target_:_port_ > ./_target_-nikto.txt" -v

Interlace v1.0	by Michael Skelton (@codingo_)
==============================================
[14:33:23] [INTERLACE] [nikto --host hackerone.com > ./hackerone.com-nikto.txt] Added to Queue 
[14:33:23] [INTERLACE] [nikto --host bugcrowd.com > ./bugcrowd.com-nikto.txt] Added to Queue 

This would run nikto over each host and save to a file for each target. Note that in the above example since we're using the > operator so results won't be fed back to the terminal, however this is desired functionality as otherwise we wouldn't be able to attribute which target Nikto results were returning for.

For applications where you desire feedback simply pass commands as you normally would (or use tee).

Run Nikto Over Multiple Sites and Ports

Using the above example, let's assume you want independant scans to be run for both ports 80 and 443 for the same targets. You would then use the following:

➜  /tmp interlace -tL ./targets.txt -threads 5 -c "nikto --host _target_ > ./_target_-nikto.txt" -p 80,443 -v

CIDR notation with an application that doesn't support it

Interlace automatically expands CIDR notation when starting threads (unless the --no-cidr flag is passed). This allows you to pass CIDR notation to a variety of applications:

To run a virtual host scan against every target within 192.168.12.0/24 using a direct command you could use:

interlace -t 192.168.12.0/24 -c "vhostscan $target -oN $output/$target-vhosts.txt" -o ~/scans/ -threads 50

This is despite VHostScan not having any inbuilt CIDR notation support. Since Interlace expands the notation before building a queue of threads, VHostScan for all intents is only receiving a list of direct IP addresses to scan.

Threading Support for an application that doesn't support it

Run a virtual host scan against each host in a file (target-lst.txt), whilst also limiting scans at any one time to 50 maximum threads.

This could be done using a direct command:

interlace -tL ./target-list.txt -c "vhostscan -t _target_ -oN _output_/_target_-vhosts.txt" -o ~/scans/ -threads 50

Or, alternatively, to run the same command as above, but using a command file, this would be done using:

interlace -cL ./vhosts-commands.txt -tL ./target-list.txt -threads 50 -o ~/scans

This presumes that the contents of the command file is:

vhostscan -t $target -oN _output_/_target_-vhosts.txt

This would output a file for each target in the specified output folder. You could also run multiple commands simply by adding them into the command file.
