“You will respect my authority” … is a sure fast way to be ignored in the business world!
Much like gatekeeping, excessive focus on policies, lack of engagement with the audience and generally mandating security policies and procedures that are not practical will likely not end with a robust, resilient security posture. Read more “Cyber Security in a business environment”

Wow a big question, right? I can’t answer this for you, obviously I’d recommend that you consider cyber insurance, however I’d also recommend that you:
I’m not going to write lots this evening on the subject, but I was reviewing a report and thought in line with some research that I started recently (but was side-tracked) and then have seen the report so purchased that instead! (Sometimes it’s easier to not do everything yourself right!)

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!

Honestly, it feels weird writing this, however I feel there’s a real issue with penetration testing and some myths that (for understandable and obvious reasons) exist in some people’s minds. So I’ve taken to trying to explain to people what an external penetration test actually entails in the real world of business. So here goes!

Defending a single server is often far more complex than people apreciate, defending a single organisation is significantly harder than a single server, defending a country… a much more complex challenge than I think people actually realise.
According to the NCSC:
The aim of ACD is to “Protect the majority of people in the UK from the majority of the harm caused by the majority of the cyber attacks the majority of the time.” We do this through a wide range of mechanisms, which at their core have the ability to provide protection at scale.
ACD is intended to tackle the high-volume commodity attacks that affect people’s everyday lives, rather than the highly sophisticated and targeted attacks, which NCSC deal with in other ways.

The UK NCSC offer and run a range of Active Cyber Defence capabilities which include the following:

Working out what exploits to care about is a tough job, kill chains, availability of exploits, complexity, data flows, controls etc. all play a part in understanding a vulnerability and how it affects your organisational risk. To support this effort I’ve started to compile a list of public exploits against CISA Known Exploited Vulnerabilities (KEV). This may be useful for defensive and offensive security pros.

When you gain access to a target node you will want to explore, the exact method you use to do this will depend upon operational security considerations, time constraints and style. You will be looking for a range of elements to support progressing an objective.
It should be noted that the objective may NOT require elevation. You may be trying to obtain data and access might already be possible using the context you have assumed.
You also may need to move from a www-data user to a named user account or get to root level of access. If so there’s a range of questions we should be asking ourselves:

Spotted on twitter (thanks Danny!):
CISA updates the known exploited vulnerabilities list (KEV) yesterday with another 38 updates!
That means an update is required for OFFESNIVE KEV!

TLDR: If you have been hunting for privescs before you will know it’s normally not a fast task, you will have a shed ton of data to look at. Sure WINPEAS is good but it’s not a silver bullet.
Here is a really small script which focuses on system administration files/scripts, scheduled tasks and scheduled task history to help you hunt for weaknesses:

Have you ever tried to SSH into a server and recieved the following error?
no matching key exchange method found. Their offer: diffie-hellman-group1-sha1Well 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?
