CUOMO: Fears that a massive global cyberattack will spread today as workers head back to their computers. The so-called "Ransomware" attack started late Friday hitting at least 150 countries. Microsoft bluntly warning that the attacks should be a wake-up call. CNN's Money Europe editor, Nina dos Santos, live in London with more. What do we know?</s>NINA DOS SANTOS, CNN MONEY EUROPE EDITOR: Chris, at the moment, we know that 200,000 computers around the world and as you pointed out, 150 countries were infiltrated. Making this the most devastating cyberattack that the world has seen so far. On the good news front, we just heard from Europol, which is the E.U.'s law enforcement agency that's closely working with the FBI to investigate who could have been behind this. They say that there is no evidence that the number of computers that have been effected has been increasing from here. That means this virus hopefully is being stopped in its tracks. And there is also no evidence that more people are paying the ransom in Bitcoins. As you pointed out, Chris, this essentially happened late on Friday when we saw this particular windows flaw which at one point have been exploited by the NSA in the past. The exploited by the unidentified group of probably criminals, experts say at this point, to try to get money from people. Essentially locking people and public entities out of their computers and demanding a ransom to get access to their data. Just to give you an idea of how destructive this has been, here in the United Kingdom, it's effectively paralyzed the health system over the course of the weekend meaning that some people have been turned away from surgeries. Over in Germany and Russia, the train that works have been paralyzed and China has also seen its university network hit really hard as well -- Alisyn.</s>CAMEROTA: Nina, the ripple effect of this is just stunning. Thank you very much for that reporting. So does the president's firing of his FBI director rise to the level of a Watergate crisis? We will ask two experts about whether or not this is a constitutional crisis next.
