Aside: Kaspersky is a Russian company.
Dude, it is well known that US is the single most powerful cyber warfare practitioner. They even had a few very successful operations in Iran and may be in China and Russia (you can guarantee that those countries won't disclose the incidents). TBH, one should be happy that US possess such power. US might be biased, but the country is at least rational.
I don't follow that logic:
> >1: The US is the single most powerful cyber warfare practitioner
> >2: Successful operations in Iran, China and Russia
> >3: But those countries won't disclose such incidents
So how you can be so sure about point 1?
