I think it depends on what one attributes the statistical fact to; it's only racism if we consider it inherent to the group. If we consider that to be a result of a particular condition that happens to be affect certain group at this point in time, and that any other group would have the same problem if subject to the same condition, I don't see how is that racism.
I think your examples are clear prejudice (and no, I wouldn't say them), but they may or may not be racism.
I suppose I just don't see what would motivate someone to slander an entire group of people based on the actions of a few. If someone is worried about cybercrime, they should say so rather than substituting "Russian" as a synonym for cybercriminal. To me that implies that cybercrime is an inherently Russian activity. Perhaps I am too quick to read racism against Russians into such an inflammatory use of the word "Russian" due to the amount of racial discrimination I have seen against Russian users while working in the game industry, where it is not uncommon to dismiss Russian gamers as probably a pirate or probably a hacker and to refuse them a level of support that would be provided to a person with a different accent or last name.
