There are several counties notorious for cyber attacks, most inasmuch for disrupting our lives and normal business, commerce, and communication hospitals, health care, and national security inasmuch as for money or ransom or blackmail, and Russia is perhaps the worst of them.
Putin has no reason to discourage the practice, and nobody cares to hack Russia because they don’t have anything really to disrupt or care about,
There are no international documented cases of hacking against Russia, but it probably does happen on a small scale. I doubt they would WANT us to know if they had any such incidents.
It’s a pretty minor of a problem in America, also, we have recently learned. Joe Biden read to us in a press conference that the Russian hacking has done no significant damages to American businesses, The stories are exaggerated. No reason to retaliate.
