ESXiargs Summary 09-02-2023 10:03

What do we know?

Adversary: Unknown, likely Criminal Actor/s

Initial Access Vector: Unknown/Unproven

Impact: ~3K+ Hosts have had Remote Code Execute and their ESXi logon pages changed (plus had encryption routines run to encrypt virtual machines, with varying success). A Second encryption routine has been deployed to some hosts; the threat actor is expanding/changing capabilities.

Risk: Further impact, Additional Threat Actors Exploit the vulnerability

It’s 2023 and people’s passwords are still really really…

If you work in marketing you are probably walking around telling everyone that we all live in a ZERO trust era, that PASSWORDS are DEAD! Ransomware is DEAD and AI is the FUTURE and we should be doing that NOW!

Meanwhile back on CYBER PLANET EARTH, most organisation do NOT have or need AI, they use passwords and well they passwords they use are shockingly bad! Howe do I know this? I do password audits and security testing, but I also look at breach data! (and we have other people publish password audit reports etc.)

The Cyber Acid Test

I’ve been working with all kinds of different organisations over the years, and I keep running into similar scenarios. The current state of the majority of organisations security postures are simply (as a broad-brush statement) far riskier than they need to be.

Conversely there are a range of common challenges I find in almost every org:

How to not lose your job as a CISO

A mRr3b00t Adventure

Join me on an adventure of rambling and exploring the idea that you can in fact not lose the security leadership game! This blog is WIP, it’s just my brain wondering around the question of: can we win the in the face of a seemingly insurmountable force? What do we do as a security leader to protect ourselves and the organisation? How do we start?

Red Team Readiness Assessment

I am seeing lots of “debate” about the value in red teaming, so I thought I would put together my thought process of how I look at as a broad stroke when I consider a generic starting position in an organisation. When I’m defending a business, I tend to ask myself (and the team/customers etc.) these kind of questions (they are not exhaustive):

Enable Number Matching in Azure MFA

Introduction

MFA was the “silver bullet” but friction and security kind of go hand in hand, the idea of a push notification and simple “authorise” is great in theory, but in practise it is vulnerable to brute force and human error. In this post we are going to check out enabling number matching authentication in Azure.

This is just one configuration option, as you can see there are loads of options for methods and specific configurations. Bear in mind the pros and cons for each one, for example SMS based 2FA can be vulnerability to SIM swapping attacks. I’m going to focus on Number Matching in Authenticator for this post: Read more “Enable Number Matching in Azure MFA” →

Cyber Security in a business environment

“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” →

Cyber Insurance: How would I decide to buy it…

Is Cyber Insurance right for you?

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:

Understand your business and it’s supply chain with regards to financials and linkages to cyber risk
Understand your current cyber asset, threat, vulnerability and therefore risk landscape
Ensure you have a good understanding to make informed decisions

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!)

Vulnerability Management Concerns by Role Type

Have you ever thought about what kind of data/intelligence you may need with regards to vulnerability management? It tends to vary at levels of abstraction based on the audiance, but don’t think the person doing the patching may not be considernig upwards or that someone in a C level position won’t care about the zeros and ones (life doesn’t work that way!)

Anyway I was talking to a friend and came up with these so thought I’d share them with the world. Have I done a decent job? can you think of others? How do you measure and report? What are your concerns?

Let’s take a look at what I came up with (this wasn’t a very long time in the making 😉 )

Myth: you must be a “techie” to lead in the CYBERS

Ok so you might be sitting here going… but Dan you send pews and do “techy” stuff… do you not lead? Well, I mean I do all kinds of things, I write business cases, I play with spreadsheets (fun right!), I integrate systems and look at data and sometimes write really bad code! (hey, the pews aren’t going to send themselves!) but… I want to talk about some realities here.
