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:

Last update we had was when LockBit released a transcript of a chat alleged to be between LockBit and the RoyalMail ransomware negotiator.
Thanks to Domonic far tagging me, we can see an update has occurred on the LB site:

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):

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

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.

Education
The loss of availability Ransomware causes is enough to make your day/week/s bad, the loss of data, bad month/quarter or longer.
Lockbit posted “Royal Mail need new negotiator.” Followed by “ALL AVAILABLE DATA PUBLISHED !”
What we actually found is that they published the chat history:

Threat Intel
Ok so the situation is as per usual a bit fluid, when this first dropped I was looking at this with a “azure” lense, however as time goes on it appears this likely also covers any Linux distro with the Azure/SCOM/OMS agents installed. This may change the profile of risk considerable, not only from a public facing attack surafce but highly likely from a lateral movement persspective. I’m going to keep updating this as more intel comes in. (sorry I’d be clearer if I had a clearer picture myself)
This week 4 vulnerabilities were disclosed which affect Azure virtual machines running the Open Management Infrastructure (OMI) agent (think PowerShell remoting). As above the scope seems to be slightly wider with regard to SCOM/AZURE and OMS/Sentinel etc. agents for Linux (I want to confirm all of this but for now it seems this is the position)
Essentially these vulnerabilities allow for both network-based remove code execution (RCE) and local privilege escalation (LPE).
