Reconnoitre

A reconnaissance tool made for the OSCP labs to automate information gathering and service enumeration whilst creating a directory structure to store results, findings and exploits used for each host, recommended commands to execute and directory structures for storing loot and flags.

Contributions are more than welcome!

Important

Reconnoitre although a well loved tool I’ve maintained for a few years now, in my opinion, pales in functionality to building your own enumeration approach within Interlace. I strongly recommend anybody looking to take Infosec beyond the OSCP to spend some time looking into this project.

Credit

This tool is based heavily upon the work made public in Mike Czumak’s (T_v3rn1x) OSCP review (link) along with considerable influence and code taken from Re4son’s mix-recon (link). Virtual host scanning is originally adapted from teknogeek’s work which is heavily influenced by jobertabma’s virtual host discovery script (link). Further Virtual Host scanning code has been adapted from a project by Tim Kent and I, available here (link).

Installation

To install Reconnoitre first make a local copy of the repository by performing the following where you wish it to be located:

git clone https://github.com/codingo/Reconnoitre.git

After you have done this run setup.py with the following:

python3 setup.py install

After setup has run Reconnoitre will now be in your path (as reconnoitre) and you can launch it anywhere using:

reconnoitre <args>

Usage

This tool can be used and copied for personal use freely however attribution and credit should be offered to Mike Czumak who originally started the process of automating this work.

Argument	Description
-h, --help	Display help message and exit
-t TARGET_HOSTS	Set either a target range of addresses or a single host to target. May also be a file containing hosts.
-o OUTPUT_DIRECTORY	Set the target directory where results should be written.
-w WORDLIST	Optionally specify your own wordlist to use for pre-compiled commands, or executed attacks.
–pingsweep	Write a new target.txt file in the OUTPUT_DIRECTORY by performing a ping sweep and discovering live hosts.
–dns, --dnssweep	Find DNS servers from the list of target(s).
–snmp	Find hosts responding to SNMP requests from the list of target(s).
–services	Perform a service scan over the target(s) and write recommendations for further commands to execute.
–hostnames	Attempt to discover target hostnames and write to hostnames.txt.
–virtualhosts	Attempt to discover virtual hosts using the specified wordlist. This can be expended via discovered hostnames.
–ignore-http-codes	Comma separated list of http codes to ignore with virtual host scans.
–ignore-content-length	Ignore content lengths of specificed amount. This may become useful when a server returns a static page on every virtual host guess.
–quiet	Supress banner and headers and limit feedback to grepable results.
–quick	Move to the next target after performing a quick scan and writing first-round recommendations.
–no-udp	Disable UDP service scanning, which is ON by default.

Usage Examples

Note that these are some examples to give you insight into potential use cases for this tool. Command lines can be added or removed based on what you wish to accomplish with your scan.

Scan a single host, create a file structure and discover services

reconnoitre -t 192.168.1.5 -o /root/Documents/labs/ --services

An example output would look like:

root@kali:~/# reconnoitre -t 192.168.1.5 --services -o /root/Documents/labs/

[*] Found HTTP service on 192.168.1.50:80
   [>] Use nikto & dirb / dirbuster for service enumeration, e.g
      [=] nikto -h 192.168.1.50 -p 80 > /root/Documents/labs/192.168.1.50/scans/192.168.1.50_nikto.txt

      [=] curl -i 192.168.1.50/robots.txt -s | html2text
[*] Found MS SMB service on 192.168.1.5:445

      [=] nmap -sV -Pn -vv -p445 --script="smb-* -oN '/root/Documents/labs/192.168.1.5/nmap/192.168.1.5_smb.nmap' -oX '/root/Documents/labs/192.168.1.5/scans/192.168.1.5_smb_nmap_scan_import.xml' 192.168.1.5

   [>] Use ncrackpassword cracking, e.g
      [=] ncrack -vv --user administrator -P /root/rockyou.txt rdp://192.168.1.5

Discover live hosts and hostnames within a range

reconnoitre -t 192.168.1.1-252 -o /root/Documents/testing/ --pingsweep --hostnames

Discover live hosts within a range and then do a quick probe for services

reconnoitre -t 192.168.1.1-252 -o /root/Documents/testing/ --pingsweep --services --quick

This will scan all services within a target range to create a file structure of live hosts as well as write recommendations for other commands to be executed based on the services discovered on these machines. Removing --quick will do a further probe but will greatly lengthen execution times.

Discover live hosts within a range and then do probe all ports (UDP and TCP) for services

reconnoitre -t 192.168.1.1-252 -o /root/Documents/testing/ --pingsweep --services

Requirements

This bare requirement for host and service scanning for this tool is to have both nbtscan and nmap installed. If you are not using host scanning and only wish to perform a ping sweep and service scan you can get away with only installing nmap. The outputted findings.txt will often recommend additional tools which you may not have available in your distribution if not using Kali Linux. All requirements and recommendations are native to Kali Linux which is the recommended (although not required) distribution for using this tool.

In addition to these requirements outputs will often refer to Wordlists that you may need to find. If you are undertaking OSCP these can be found in the “List of Recommended Tools” thread by g0tmilk. If not then you can find the majority of these online or already within a Kali Linux installation.

Dockerfile

First step is to install docker if you do not have it installed already. Docker Installation

Basic Usage:

cd <Reconnoitre Directory>
docker build -t reconnoitre .

docker run reconnoitre -o outputdir -t 127.0.0.1

If you want files to exist locally you can mount a directory to the Docker container

cd <Reconnoitre Directory>
docker build -t reconnoitre .
mkdir /path/to/dir

docker run -v /path/to/dir:/outputdir --services -o outputdir -t 127.0.0.1
