Infrastructure Recon Script

Hello everyone, it's been a while. :) Just wanted to share something I've been working on with you all.

I've developed a recon script for infrastructure testing which works off a CIDR or a list of IPs. It splits given IPs into groups of 64 (as nmap performs TCP scans on hosts in groups of 64,) launches nmap scans on each group as background processes and then merges the results together once every group has been scanned. The theory behind this is that port scans on over 64 hosts will complete in the time it takes to scan one group of 64 hosts.

From here, it analyses the port scan results and launches service-specific scans. It also creates lists of IPs by service, making any extra checks applicable to all hosts found with a specific service open.

You can find it here. It's still lacking a bit in documentation and usability- there's tools you need to install that I haven't noted down anywhere- but it's 80% tools found on an average Kali Linux build anyway. ^^ I do also want to improve the service scan scripts and see if there's anything I can add to them. Recently got it up and running fully so thought I'd share it.

Otherwise, I am working my way through Burp Suite Academy right now. My plan is to post a review on it here when I've covered what I want to there. Been slacking on it a little since starting work but I'm working on that.

EDIT: Still problems with the analysis section- I had a run through where everything was picked up but there's an issue stopping all hosts and services being picked up. Working on this.

UPDATE: Changed the flow of this and issue seems to have been addressed. :)

Something I thought of only after sending my last post about programming. Programming in movies and shows (mostly it comes up in tv) is pretty inaccurate in a lot of places. I can think of a few times they got it right:

Hackers. Nearly everything in that movie in terms of how hacking actually works is pretty accurate, especially since most of it is using social engineering to steal people's passwords. They don't build some complicated program to take down the internet or whatever, they write a basic script to just steal as much data as possible.

Matrix Reloaded. Trinity uses nmap (a real UNIX utility program) to scan a server and notices that SSH is running. Then she uses sshnuke to exploit a bug in the server that gives her admin access. The bug and the script to exploit it are both real (the exploit has been patched in real life a while ago).

There's nothing flashy about any of this so it's not too interesting for an audience. That's why you never see it. Same reason even experienced sword fighters like to hit each other's swords in movies: it's less accurate but it's more fun to watch.

Nmap: A Comprehensive Network Mapping and Security Scanning Tool

Nmap is a free and open-source network scanning utility that can be used to discover hosts and services on a network, as well as to identify potential security vulnerabilities. It is a powerful and versatile tool that is used by security professionals, system administrators, and penetration testers.

Nmap can perform a variety of scans, including:

Host discovery: Nmap can discover hosts on a network by sending probes to IP addresses. This can be used to identify all devices on the network, even those that are not actively responding to network traffic.

Port scanning: Nmap can scan a target host or network to determine which ports are open and which services are running on those ports. This can be used to identify potential security vulnerabilities, such as open ports that are not being used by a service.

Version detection: Nmap can detect the version of software running on a target host. This information can be used to identify vulnerabilities in the software, as well as to determine if the software is up-to-date.

OS fingerprinting: Nmap can determine the operating system running on a target host, even if the OS is running behind a firewall or NAT device. This information can be used to identify potential security vulnerabilities and make informed decisions about firewall and access control policies.

Scriptable: Nmap can be automated and extended using Nmap scripts. Nmap scripts can be used to automate various tasks, such as detecting open ports, performing vulnerability scans, and collecting information about a target host.

Penetration testing: Nmap can be used to perform penetration tests on networks. This can be done by scanning for open ports and services and then exploiting any vulnerabilities that are found.

Network troubleshooting: Nmap can be used to troubleshoot network problems. This can be done by scanning for hosts that are not responding to network traffic, or by detecting services that are not running on hosts.

Here are some tips for using Nmap safely and ethically:

Always get permission before scanning a network.

Do not scan networks that you do not have permission to scan.

Do not use Nmap to attack or exploit networks.

Use the least intrusive scan type that will achieve your goals.

Be aware of the laws and regulations that apply to network scanning in your jurisdiction.

C-Cracks/OSCP-Automation was recognised!

So I found out that 2 years ago, my OSCP automation repo was actually posted by a company named National Cyber Security Services. :D https://m.facebook.com/ncybersec/photos/oscp-automation-a-collection-of-personal-scripts-used-in-hacking-exercises-1-enu/1502887116548674/

I actually found this because I'm about to do some HTB and I was going to use that as reference material.

It may seem like such a minor thing, but it's actually amazing to see that a company saw value in it enough to post about it (even with the fact that it was extremely basic and the enum script is now an older version before I debugged due to being a complete noob with GitHub at the time.) Fangirl moment. XD

Repos below for the curious, though that GitHub account isn't active anymore (I stupidly registered it with a university email and never bothered to look into getting it back!)

I am actually thinking of re-creating something like this as I start up with HTB again (kinda got the hacking bug...)
