Wouldn't hackers rather attack people with the new Windows 11 than older operating systems? This is what I think.
Malicious actors will go after whatever is easiest or gives them the best payout. Windows 11 only just recently started overtaking Windows 10 as the dominant user workstation. It will continue to swing most likely as 10 goes EoL but if there are a bunch of Windows 10 workstations floating around out there with open, known security flaws that aren't being patched with updates, you can rest assured that they'll be more than willing to exploit that if they have the opportunity.
Attacks aren't even always obvious anymore. Sometimes all the want to do is sneak a little software onto the system so they can get in easier later, monitor, or as often is the case, give commands as the workstation as part of a botnet for use in a larger attack elsewhere. There have been stats out in the past that workstations out of support or which did not have the latest security updates often did form a large portion of PCs in various botnets.
Again though, it's up to the user to weight his risk from exposure. You're never 100% safe even if you are fully up to date. It is usually best practice to have active support though.
FYI, I won't claim to know it all or be an absolute authority on PC security, but I have been working in the IT/support field for 25+ years now. I'm not a huge fan of Windows 11 over 10, but there are sound reasons to move up rather than being unsupported.
