Interlace - Easily Turn Single Threaded Command Line Applications Into Fast, Multi Threaded Ones With CIDR And Glob Support


Easily turn single threaded command line applications into fast, multi threaded application with CIDR and glob support.

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 variable that can be used in commands as _port_. This can be a single port, a comma delimited 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
80 Single port
1-80 Dash notation, perform a command for each port from 1-80
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 done using CIDR notation, dash notation, or a comma delimited 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
_host_ Works the same as _target_, can be used interchangably.
_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_ > ./_target_-nikto.txt" -v
==============================================
Interlace v1.0 by Michael Skelton (@codingo_)
==============================================
[14:33:23] [THREAD] [nikto --host hackerone.com > ./hackerone.com-nikto.txt] Added to Queue
[14:33:23] [THREAD] [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_:_port_ > ./_target_-_port_-nikto.txt" -p 80,443 -v

Run a List of Commands against Target Hosts
Often with penetration tests there's a list of commands you want to run on nearly every job. Assuming that list includes testssl.sh, nikto, and sslscan, you could save a command list with the following in a file called commands.txt:
nikto --host _target_:_port_ > _output_/_target_-nikto.txt
sslscan _target_:_port_ > _output_/_target_-sslscan.txt
testssl.sh _target_:_port_ > _output_/_target_-testssl.txt
If you were then given a target, example.com you could run each of these commands against this target using the following:
interlace -t example.com -o ~/Engagements/example/ -cL ./commands.txt -p 80,443
This would then run nikto, sslscan, and testssl.sh for both port 80 and 443 against example.com and save files into your engagements folder.

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.

Glob notation with an application that doesn't support it
Interlace automatically expands glob ranges when starting threads. This allows you to pass glob ranges to a variety of applications:
To run a virtual host scan against every target within 192.168.12.* using a direct command you could use:
interlace -t 192.168.12.* -c "vhostscan _target_ -oN _output_/_target_-vhosts.txt" -o ~/scans/ -threads 50
Yet again, VHostScan does not having any inbuilt glob range format support.

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.
