A couple of decades ago, iirc, SANS.org ( IF I’m remembering who it was who did it ) put a fresh-install of MS-Windows on a machine, & connected it to the internet.
It took SEVERAL MINUTES for it to be broken-into, & corrupted, botnetted.
The auto-attacks by botnets are continuous: hitting different ports, trying to break-in, automatically.
I’ve had linux desktops pwned from me.
the internet should be considered something like a mix of toxic & corrosive chemicals: “maybe” your hand will be fine, if you dip it in for a moment & immediately rinse it off ( for 3 hours ), but if you leave you limbs dwelling in the virulent slop, Bad Things™ are going to happen, sooner-or-later.
I used to de-infest Windows machines for my neighbours…
haven’t done it in years: they’ll not pay-for good anti-virus, they’ll not resist installing malware: therefore there is no point.
Let 'em rot.
I’ve got a life to work-on uncrippling, & too-little strength/time left.
“but I don’t need antivirus: i never get infected!!”
then how come I needed to de-infest it for you??
“but I don’t need an immune-system: pathogens are a hoax!!”
get AIDS, then, & don’t use anti-AIDS drugs, & see how “healthy” you are, 2 years in.
Same argument, different context-mapping.
Tarpit was a wonderful-looking invention, for Linux’s netfilter/iptables, years ago: don’t help botnets scan quickly & efficiently to help them find a way to break-in…
