Hello. Where can I find a list of virus outbreaks that occurred in the last 30 days, 90 days and last year? Thanks ;)
Actually, I think that such an information is not always freely available. Someone may speculate after gathering and aggregating this kind of statistics.
However, it should be possible to maintain own research about subject. And, maybe, some public or social (official) security or legal companies outline outbreaks yearly, monthly, weekly. So, it can be cyber security companies (like F-Secure) with their white papers. Or independent cyber security companies / researchers with their investigation on field. Or something more local like recommendations or public warning information about cyber threats from respective authorities.
Did you try to use any web search engine (for example, Google Search) with such search query? Perhaps, some resources can be with on-going research about statistical information about outbreaks.
Anyhow, under F-Secure Community were some topics with this request. And, usually, no feedback later about found workaround or place or performed steps.
