Abhijit TripathiGUEST
So you see, that is where, very rightly mentioned by Chirayu, the entire methodology of entering into the virtual environment, creating a new virtual server, that was done.
Abhijit TripathiGUEST
And in many cases, we found that because the environment was ESXi, so that is the reason, that is one of the reasons why the Linux version of Akira was created to target virtual environments which are hosted on ESXi.
Abhijit TripathiGUEST
Using the vSphere client, they were able to log in, and they were able to encrypt the entire thing.
Abhijit TripathiGUEST
And that is the reason for having the Linux version of Akira.
Travis WentworthHOST
Nowadays, you want to learn how to pin up an IO board, pick up a Raspberry Pi for $100 and go watch a YouTube tutorial for free.
Travis WentworthHOST
You want to learn how to run Docker containers, Kubernetes, virtualization, run Proxmox, run the free versions of VMware and ESXi.
Travis WentworthHOST
You have virtualization.
Travis WentworthHOST
You're learning cloud.
James AzarHOST
This is the flaw that gives attackers the ability to execute code on vCenter servers, the central management layer for the VMware virtualization environments.
James AzarHOST
In practical terms, if you compromise vCenter, you can reach every ESXi host and every virtual machine it does manage.
James AzarHOST
That is why ransomware gangs and groups prize it.
James AzarHOST
One entry point, total environment access, maximum leverage for extortion.
James AzarHOST
And ransomware operators have already demonstrated the ability to encrypt ESXi data stores wholesale, taking entire data centers offline in just minutes.
James AzarHOST
CISA has already added the vulnerability to its KEF catalog, and it's ordering its federal agencies to remediate.
James AzarHOST
Patch vCenter server immediately to the version specified in VMware's latest advisory.
James AzarHOST
If patching does require a maintenance window, restrict vCenter management access to a dedicated management VLAN with no internet exposure.
Darin ZookHOST
What can go wrong? Nothing.
Nick KuhnHOST
Nothing can go wrong with an in-place upgrade of ESXi.
Nick KuhnHOST
It just works.
Nick KuhnHOST
I just
Keith LeeHOST
repave, repave, repave, repave.
Keith LeeHOST
Yeah.
Nick KuhnHOST
I got too much workload to repave my ESXi environment at this point.
Nick KuhnHOST
You definitely do.
Eric SironHOST
So...
Eric SironHOST
ESX is going to eventually, whatever, you know, Broadcom did to them, whatever happens, then they did it themselves.
Eric SironHOST
I don't feel, I don't feel that.
Eric SironHOST
So,
Andy SyrewiczeHOST
Yeah, Broadcom and VMware continue to frustrate me.
Andy SyrewiczeHOST
I...
Andy SyrewiczeHOST
You know, I remember ESX, I think the first version of ESX I ever used was version 3.
Andy SyrewiczeHOST
And I was certified on 4, certified on 5, and then after that I went whole hog Hyper-V.
Brian JohnsonHOST
Was it April or May or something of this year? Microsoft kind of pushed through an encryption upgrade for accounts that would be Kerberostable so that they take more horsepower away.
Brian JohnsonHOST
you know therefore time therefore you have a lower rate of success at cracking those hashes so i my my success rate in cracking curb roastable hashes has dropped significantly but anyway that was in good shape no as rep roastable users couldn't get into any sql boxes took a look at scanning all their land side stuff, looked for MFPs with default passwords, out of date ESXi and VMware boxes, all that stuff looking really, really good.
Brian JohnsonHOST
And their file shares yielded just a couple things that were more like, Well, people had a passwords.doc and it was right sitting there on their desktop.
Brian JohnsonHOST
And that was interesting, but it didn't have anything to do with their corporate accounts.
Rob HirschfeldHOST
And I see that in labs, and I see that where people are doing exploration, and they're like, okay, I want to... run a model but the models today as we've talked about many times get are so big that it's not really a you know we're getting to a whole machine useful models real useful models get whole machine uh gpu assignments um and then so you there's you wouldn't virtualize that you also wouldn't be conformant to the VMware spec on this, meaning you're not buying gear that's a VMware machine for this.
Rob HirschfeldHOST
They have a pretty narrow spec, and running ESX on a machine is tricky, and you can't mix architectures on VMware machines.
Rob HirschfeldHOST
So, you know, you're talking about buying clusters of machines like that, and...
Rob HirschfeldHOST
Maybe we're getting more CPU heavy machines now that AI is doing more inference, but I'm not sure how the pricing model lines up from a CPU core assignment piece.
Bob PlankersHOST
Well, the nice thing about our Kubernetes as well, the VKS stuff is it runs independently.
Bob PlankersHOST
It used to be, you had to, you could only upgrade it when you upgraded vCenter and ESX and vSphere and all that stuff, but now it's decoupled.
Bob PlankersHOST
So, you know, the upstream Kubernetes projects come out like 1.37 is the latest version, latest release version for them right now.
Bob PlankersHOST
They're working on 1.38, you know, when 1.38 ships, uh, We will have it ready pretty quick there.
Jake WilliamsHOST
And they first published on them in 2025.
Jake WilliamsHOST
But that was around... around hypervisor espionage, they were targeting vCenter and ESXi.
Jake WilliamsHOST
And they said even then, end network appliances, right? But now, right, they've got a publication out where they're talking about compromise of network devices, and very specifically, right, targeting iOS XR.
Jake WilliamsHOST
So Cisco's iOS XR.
VedranHOST
But wasn't being used even close to its full potential is the artist tab as well, just like yours.
VedranHOST
I decided to kind of like do some changes in the data center design and introduce one first significant change is that I'm now connecting all of the ESXi hosts via optical connection to the switch.
VedranHOST
So that's the first thing.
VedranHOST
From all of the racks, I have a central switch.
