If you make your machine look like a malware execution sandbox, a lot of malware will terminate to avoid being analyzed. This is just part of the cat and mouse game.

Yea sophisticated malware checks how many CPU cores PC has, how much hard drive space, some even check hardware temperature or if any debuggers are present. Windows malware got pretty sophisticated in the last 30 years.

Yes, and don't forget to install the VirtualBox guest extensions in your host machine to make it looks even more like a VM!

Is there any downside to unironically doing this? Seems like it'd actually work.

Expect Oracles lawyers to send you a bill.

Just add those two keys into your registry: https://github.com/Unit221B/Russian For persistance install the russian keyboard driver, and switch back to your original.

That's a funny way to combat Russian made malware but I think Russian malware checks which keyboard language you are currently using and not which ones are in total present on your OS.

Nope, it checks which keyboards are installed in these reg entries, not which are currently used. That's the well-known windows trick every ms admin should know

It’s not much harder to just harden your system to not be vulnerable in the first place, and that protects your from a lot more.

Please tell me what tools you use to receive future zero-day vulnerability patches.

Qubes OS should protect you even from unknown vulnerabilities as long as you use its compartmentalization approach. Works for me (or so I hope).

Is there a way to check which one is currently in use? There must be. So Russians are slacking on this one? Also they could check in which language are files and folders named or they could check timezone or something. Years ago I loved to read malware RE articles and I remember they also checked for Belarussian, Ukrainian and most of the ex-USSR countries' languages. Isn't the most efficient way to check external IP address of the device, ofc if it has one.

any good read on how good they are nowadays ? (my background is cracking games 35 years ago :-))

geolocations of IPs change all the time, malware would need to speak to some server somewhere to get a current list. the russian keyboard method doesnt have the same risk of discovery

I'm not a reverse engineer or a white hacker but I like reading about it. Most of the malware is made for Windows OS because of the Windows' enormous market share.

Majority of information about Windows malware I get from big computer security companies' research blogs like:

https://www.trendmicro.com/en_us/research.html

https://www.proofpoint.com/us/blog

https://research.checkpoint.com/

https://blog.talosintelligence.com/

https://www.welivesecurity.com/en/

Microsoft also got good security research blog: https://www.microsoft.com/en-us/security/blog/

Majority of the research combes down to researching malware's capabilities regarding malware persistence, anti-VM techniques and anti-debugging techniques.

Here is for example good compilation of malware's anti-debugging and anti-VM techniques:

Prompting a good LLM to convincingly act like a native isn't hard, neither is jailbreaking it if necessary. The hard thing in this case is verifying that it really does that.

Nah, it's not reproducible. It can certainly give you some common phrases, but to create an entire personality with its own set of speech patterns is a different thing. For example, Claude can suggest following friendly conversation starters to sound like a native (a quote below): Popular combinations for texts: "Прив! Чё как?" - "Hi! How's it going?" "Дарова, живой?" - "Hey, you alive?" "Салют! Как сам?" - "Hey! How…

lmao if you start conversation like this, other person will think you’re 12 years old
