Russian-Linked Hackers Conceal Malware Inside Hidden Hyper-V VMs

A Russian-aligned threat group secretly ran Alpine Linux virtual machines inside Windows 10 systems to hide malware and evade EDR tools, in what researchers call an unusually stealthy use of native virtualisation features.

Using KolibriOS to draw something for the OSC on Tumblr: 2024-04-12 03:00

it's been ages since the last time i played with the VM workstation i had on my tablet PC, and now i'm back again with cool things to show here. :D

Back in 2022, before I was an object show fan, there was an application which enabled to run real operating systems on a smartphone or a tablet. It was an emulator which ran operating systems using the x86 or x86_64 processor technology. Of course, I'm talking about Limbo Emulator, in which it has QEMU as the whole framework. It wasn't just based on QEMU, but was basically just QEMU, ported to ARM processors, with a graphical interface. I once created a VM, created a disk and formatted it using DOS, and ran KolibriOS on it.

However, it is to be noted that the VM runs so slow because the tablet has an ARM processor, and ARM processors, including ARM-based ones can operate only in about 1-2 megahertz when emulating x86 or x86_64 chips. The only operating system which can be booted from start to finish in less than a minute is KolibriOS, and let me tell you, it's much more fun to work with.

Then, when I opened Tinypad and wrote something down, I thought to myself, "Hey, what if I made something like a souvenir for the OSC on Tumblr using this operating system? It'll be like the next leap forward to the power of computing. It'll definitely be something like a wonder of lightweight OSes!! It doesn't have to be big, but little. I'm gonna draw something for the OSC!"

I then got an idea. A bright idea. I can draw a TPOT character ship!

When I chose a ship to draw, I considered 2 things:

The ship should be a popular one.

The ship contains characters which are easy to draw.

I had many ideas for that, but the closest ones so far were Fireafy (Firey x Leafy), and Sawty (Saw x Gaty). Both of these ships are popular, but they have either one or both of the characters in each ship which are hard to draw, especially considering the processor is too slow to render curves properly. Even drawing Fubble (Fanny x Bubble) is somewhere between difficult to impossible. Draw a curve very slowly, to the point you would never see the pointer moving, and you get a nice one. Draw it faster, and surprise, it's a collection of lines connected to each other, or in other words, a polygon.

And so, I settled for Coinypin (Coiny x Pin). It took a long time to neaten up everything until I got the result in which I liked. Yeah, I know it's just a bunch of lines and circles, but who cares? I'm happy with it though.

apologies for making a spelling error on the filename, it was supposed to say "tpot coinypin" but i was too lazy to rename it, and then i did it afterwards lol

This is a story in which I did the unthinkable. Next TPOT ship to be drawn on KolibriOS is Sawty (Saw x Gaty), sooner or later, and I hope it turns out fine as the Coinypin one.

The end.

Love,

Retro computer emulation/virtualization resources

Not too long ago, it was one of my hobbies to recreate and emulate old machines and try to use them in a somewhat 'legit' way in order to experience how using them in an accurate time-period might have felt like. While it's always better to use a real machine, it's also important to note that time-accurate machines are essentially a 'ticking bomb'. Some of the electronics inside can go bad at any given time, like capacitors, and other critical components might also go bad due to humidity, moisture in the air, changes in temperature, etc. Plus, they are not always cheap and they take space that you might not have.

This is why I prefer using emulators and virtualization software in order to virtualize a time-period accurate machine that I can use. This is the software I found that I like the most, and what systems I use them for.

DOSbox-X

This is a modified version of DOSBox that includes support for multiple video devices including 3dfx emulation (Voodoo), networking, and even printer support (emulated, but AFAIK it only prints in black and white). It's perfect for MS-DOS and Windows (1-3.11) emulation. Technically you could even install Windows 95 in it.

DOSBox-X: Free, cross-platform and complete DOS, Windows 3.x and 9x emulation package

86-box

This is the way to go if you want to emulate old retro systems. No questions. The best part of it is how flexible it is. You can select the motherboard, the processor you want to emulate, the video card, you can also enable 3dfx support up to the Voodoo 2 (but it also emulates a Voodoo3 and the Banshee), sound card, literally every detail. It's like building a PC, but virtually. And it has hardware from the old 8086 IBM PCs to more modern Pentium 2 machines. It also has network and printer support.

The downside is that since it's low-level emulation, you need a 'beefy' CPU with very good single thread performance in order for more modern systems like Windows 9x and ME to run more smoothly. Another flaw is that for some reason the FP emulation for older processors doesn't work properly for some reason, so you might prefer to use DOSBox-X if you want DOS emulation. The 3dfx emulation is also 'so-so' and not very great, but it works.

It also requires valid ROMs, but you can search for a valid ROMset online (check Github) if you want to use it. For legal reasons, I can't provide links to them, but they are not hard to find.

Emulator of retro x86-based machines

VMWare Workstation Player

I choose VMWare over other virtualization solutions because of it's graphic drivers capable of running relatively new games from the mid 2000s, and because unlike VirtualBox (since version 6) it still supports old Windows versions, including XP, 9x, ME and old NT systems.

Broadcom wants you to buy a license for the Pro version so they hide the links to the free Workstation Player version. But they are still available and they even release updates once in a while (yes, it's free of charge).

In the link I'm providing, go to the 'player' folder and select the latest version (higher number, now it's 17.6.1) and your system to download VMWare Workstation Player. Then go to the 'ws' folder and select the same version and system, but then select 'packages' to download a matching copy of vmware tools.

Finding software

If you need software, there are three places you need to look for. One is archive.org, the other is WinWorld PC, and the other is Vetusware (requires an account). I can't provide links so search for them on your own. I also browse sites like oldversion.com, but I don't trust these too much, so go at your own risk (or better yet, don't). Naturally you should always buy the software you use, whenever it's possible, and use backups of your legally owned software.

Did you like this post?

I will make more posts in the future about how to set up these emulated machines and how I work with them.
