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

How to get some OPSEC with Kali?

There are major questions that must be answered here!

How do we change the hostname in KALI Linux?
How do we change the default TTL to look like a Windows Machine?
How do we pretend to be a SAMSUNG device/How do we change our MAC address?

Getting into Cyber

How to get into Cyber? It’s EASY!

Quick, I’ll tell you a little secret… to get into CYBER you must first follow this guide:

Now if you are going to GET INTO CYBER you need to have a range of things:

Computer Hacking Skills
Num-chuk Skills

Right ok, so let’s get some Hacking Skills!

Head over to KALI LINUX and download KALI

CrackMapExec (CME) on Windows

Ok this is going to be really short post, but expect more later! Did you ever want to run CME but you were stuck on a Windows machine? Well don’t worry you can! How do we do this?

First we download CME

https://github.com/Porchetta-Industries/CrackMapExec/releases/download/v5.4.0/cme-windows-latest-3.10.1.zip

Extract the zip file

Make sure you have python3 installed!

Ransomware + Mega = Mega Cyber Pain

Did you ever read about ransomware actors? They often use mega upload to exfiltrate data! So I figured, why would we not detect this with MDE?

I mean sure we should probably block this with a custom indicator using Web Content Filtering and sure it would probably get blocked by Protective DNS but let’s say for whatever reason you don’t have those in place, let’s look at a really simple query to find mega connections in MDE:

Threat hunting with some funny results!

You never know what you will find when you go hunting! So here’s a quick tale of an explore I did using Advanced Hunting!

I went hunting here in Advanced Hunting:

Simulating Human Operated Discovery

Did you want to check out some of your detections? This isn’t everything of course but it’s a simple batch file to simulate a range of enumeration techniques used by actors like CONTI or LOCKBIT affiliates/operators:

Leadership

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.)

Cloud Adoption Security Review

Anyone that knows me, knows I love maturity assessments and tools (I’ve built a few, and run LOADS more) so this morning when I saw this on LinkedIn I had to start to get some understanding! I’ve not even had a cup of tea, but let’s see what this looks like!

Current State Cyber Challenges and why communication is important

Currently I’d list some of the major challenges we face as a civilisation as the following (clearly not exhaustive etc.)

The general population largely don’t understand cyber
Lots of people think there is nothing they can really do
People have shockingly bad personal cyber security
A large number of organisations have shockingly poor cyber security postures
People’s passwords are often ridiculously weak
People re-use passwords all the time
People seem to believe we have “magic nation state cyber shields”
Organisation’s largely do not invest adequately in cyber security
