Hacking
Working in Cyber security can expose you to all kinds of information. I’m an offensive and defensive security architect and occasional (haha that’s daily right!) pew pew slinger (pentester) and I am also a threat intelligence practioner (CTI) (we need The Many Hats Club back!). Which is why sometimes when things appear on the internet I think I decide to take a look.

In this scenario it is assumed you do not have credentials, but you do have either adjacent or routable access to an Active Directory Domain Controller and can access common ports/services such as: LDAP, LDAPS, SMB, NETBIOS, KERBEROS, DNS

Regarding: CVE-2023-23397
This is a fast publish, use at own risk.
See guidance from Microsoft: CVE-2023-23397 – Security Update Guide – Microsoft – Microsoft Outlook Elevation of Privilege Vulnerability
If you need to mitigate the latest Outlook vulnerability which abuses an SMB/WebDav call using the Calendar invite feature you can consider the following:

This post started as a reply to a great topic on LinkedIn, but I hit the character limit so now it’s a blog post!
Years ago I simulated attacks (authorized obviously for the people that have wild imaginations) on a customer which included a physical attack where I walked into a healthcare organization, armed with a suit a smile (and a USB key) I needed to gain access and attempt to move laterally and escalate privileges.

This morning before I got on with some more dull affairs of business, I saw the following:
2023-2030 Australian Cyber Security Strategy Discussion Paper
How we (humanity) and people (including governments etc.) respond to the changing digital landscape and cyber threats that affect society and humanity as a whole is really important. It’s great to see the Australian government using an advisory board and panel structure as they look to review/renew their national cyber security strategy. I’m posting this to raise awareness as I think these things are ever so important that people in the community, industry, academia etc. give their inputs, help and support to the people charged with the incredibly complex task of developing and implementing cyber strategies at country scale! A task not so simple, hence they are calling for inputs as part of a general consultation request from people and organizations.

There are so many lists of “tools” of “free resources” for “cyber” etc. Well I don’t want to make a list of stuff for social media, this isn’t the TOP x tools, this is simply some resources that I use on a regular basis that should give people a fairly good idea of where to start looking. Cyber sleuthing is a mixture of:

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.

Vulnerabilities
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.

Cyberwarfare in Ukraine was hyped as a MASSIVE thing, yet largely it’s been more bark and bite, but perhaps people need to understand that you can’t just “CYBER” a remote network, and even if you could, let’s say you get RCE on 30 networks in a country, so what? There needs to be value, purpose and something that will support other objectives, this isn’t a CTF.
