Caught: A Hacker Adventure

It was a dark and stormy night, and a lone figure sat hunched over their computer screen, typing away at lightning speed. This was no ordinary person – this was a hacker, one of the most skilled and dangerous in the world.

Am I a criminal or am I a cybersecurity…

Whilst the common person will largely link the words “hacker/hackers” to criminal the reality is hackers are scientists/artists/creators/ComputerOperators and the choice of being a criminal or not is down to actions and consequences. So the debate about if you identify as “hacker” does that make you a criminal, well it’s nonsense isn’t it. I could call myself a pony but it won’t make me one, much like I could call myself a criminal and I could be entirely law abiding.

CVE-2022-39952 Fortinet Global Exposure

There appears to be a new RCE out for Fortinet devices as per this post (it’s against FortiNAC as far I am aware so this is probably a much smaller exposure footprint than all fortinet devices):

https://www.fortiguard.com/psirt/FG-IR-22-300

There’s also this in FortiWeb (and well they released 40 odd fixes to various bits)

https://www.fortiguard.com/psirt/FG-IR-21-186

When we consider security edge devices and the risks these may pose to organizations and society as a whole it’s important to understand that these are no trivial matter. These are “security” appliances that are there to protect your organizations, to provide remote access as well as protect network egress etc.

Fortinet are not the only vendor to suffer from these types of vulnerability (Remote Code Execution – RCE) however there do appear to have been quite a few of these when looking historically.

failed to open stream: Permission denied in /var/www/wordpress

I was doing some WordPress foo on the site (I know right, shockingly I don’t want to hand craft a website and I’d rather be helping customers or really anything else really) and I came into this error when I was installing the wpforms plugins:

 file_put_contents(/var/www/wordpress/wp-content/uploads/wpforms/cache/addons.json): failed to open stream: Permission denied in /var/www/wordpress/wp-content/plugins/wpforms-lite/src/Helpers/CacheBase.php on line 215

How would I apply to the role of “Head…

I was pottering about (not like a wizard, more like a cold infected zombie!) and an email hit my mailbox with the “Head of Cyber Architecture” at BA. I have no intention of applying but I thought.. I wonder if this is a good exercise to show people how I would go about the exercise? Well to even begin this I need to write down some notes. So I guess here we go… how far I get into this “fantast football” style scenario who knows, but hopefully it will show some people how I might do things! First up let’s look at the raw requirement:

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
