it's a zero-day when it is not patched but still exploited
Is it really a "zero-day" if it's being used months later?
zero day has always meant an unpatched vuln.
A zero day just means that the vulnerability hasn't been patched.
Its not a "zero-day exploit" if there's been a patch out for it for N days, where N>0, right?
It is a 0-day because the vulnerability was disclosed publicly before the patch was made available.
these zero days are already the status quo?!
Aren't all vulnerabilities zerodays and therefore unpatched at some point?
"0 day" just means that the vulnerability was reported before it was fixed.
If it's got a fix it's not a zero-day.
