Ever stuck in an environment where your internet access isn’t what you want it to be? Ever need to exfilrate data and bypass some DLP? Obviously I’m talking like a pentester (don’t use this if it beaks policies on anohers assets) so this is useful for some scenarios in testing but also in real life!

If you are new or like me forget the bazzilion command syntaxes in the world, the use of the man command will be super helpful as well as google foo! To help people on their way here are some example of basic SMB tools, these come with kali.
SMB typically operated on TCP 445
How long should you test brute force password attempts for?
Well, a recent Microsoft report showed the average RDP brute force attack over the internet lasted about 3 days. Now let’s take a look at what a single attacker machine (IP) can send to a single target server over a well-connected network (1GBE low latency):

Checking an environment configuration is one of those things where it’s easy to say and harder to do. If we take the cyber essentials standard and look at the requirements, they are quite different from say the CIS baselines. This alone makes for some fun, let’s investigate this further:
CIS baselines are based on a specific component e.g., Windows Server or Windows client and is contextually aware of roles: e.g., Domain Controller vs Member Server.
Is this registry key set?

Have you ever tried to SSH into a server and revieved the following error?
Well that’s probably becuase you are using a bit of kit with legacy software or firmware.
Then when you try to SSH and you add diffie-hellman-group1-sh1 you get the following back?

Have you ever wanted to run a quick test of egress ports from userland from a windows machine?
Well worry not, I didn’t even have to write anything, the nice people at Black Hills security have done it for us. However I did decide that there’s a few other things we might want to do, so I made a quick modification, now we have colours, randomisation and some sleeps.

Ok so i posted a snipped of PowerShell on LinkedIn for hunting the confluence logs using a pattern match for ${ (after we have URL decoded (twice). This is just an example of how to parse log files using PS1 so it’s clearly very basic but i wanted to give people an idea of what we do when we “GREP” the logs:

According to NIST, a denial of service (DoS) is:
“The prevention of authorized access to resources or the delaying of time-critical operations. (Time-critical may be milliseconds or it may be hours, depending upon the service provided).”
denial of service (DoS) – Glossary | CSRC (nist.gov)
a distributed denial of service (DDoS) is:
“A denial of service technique that uses numerous hosts to perform the attack.”

If you want to keep up with the world of cyber security the fastest place is twitter, however that’s not the only place and whilst tweetdeck and twitter itself are incredible useful, you also are going to want to check out other areas. Inspired by a friend’s tool I thought I’d just knock up a list of sites that have useful cyber security information on:

So, you have a driver to achieve cyber essentials, great stuff. Now if you are a business of reasonable size and scale this activity requires a bit of planning, context and lots of access and data. This could be via a distributed team or via a dedicated project team. In this post I’m going to look at what you may need to conduct the planning, discovery, assessment, and certification for Cyber Essentials and/or CE+.
