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):

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.

Pro Russian Hacktivist Groups

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.

Is my house spying on me?

Do you ever get the feeing you are being watched? What about listening to it? Do you ever talk about a subject and then see it appear in adverts despite never using a computer to search for it?

Well don’t worry there’s lots of reasons as to why this can occur, and whilst you might want to think someone is spying on you, the truth is they probably aren’t looking for you, but they might be harvesting your data.

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:

DNSSEC – why not having a signed zone is…

Firstly, what is DNSSEC?

Ok read all that good. What we are talking about here is signing a DNS zone to “assure” that the client is getting DNS responses from the right ZONE data. DNSSEC does not encrypt the conversation between DNS client and DNS server. It does enable the client to be able to check if the data it gets back is valid. In short what we are doing is validating that the “data” being returned is authorized and not tampered with.

Lockbit 3.0 and Royal Mail – Chats Published

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:

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

ESXiARGS Ransomware – Global Incident

Thousands of ESXi hosts around (some of the) globe have been encrypted by cyber criminals. This post is a fast publish showing some of what has occurred, it’s impact and now includes limited remedial advice.

If you have been affected by this ransomware event there is an attempted recovery script by CISA

Leadership

Why is security so hard?

It requires being thorough.
It required documenting things.
It requires conducting training and drills.
It adds what can be viewed as additional effort/cost to the primary goals (sell widgets/services/time)
It involves weird and wonderful ways of abusing functionality that is not always apparent or expected, thus to the typical consumers/user of a service, the idea that it might be abused actually seems very unlikely (to a criminal or security pro, the idea it will be abused seems far more likely based on threat intelligence etc.)
