OK, it seems that Microsoft is not the only one fighting over illegal information request and that's the good job they're doing but according to their results of last year, about 72000 law enforcement requests were fought over last year. What were the cases of last year? Were they those things that were triggered by the standard-type criminals, or perhaps those things were done by cyber-criminals? Well, even then, the FBI has to take some responsibilities in fighting cyber-criminals without making contact with IT companies to retrieve information about what have the cyber-criminals done. There must be other ways to tackle those bad guys. There should be a standard way of making information based on the cyber-victims' complaints, but the next stage is about finding the information about the attack as well as to find the source through research without any privacy invasion.
And there was a real example about the enterprise customer being targeted by FBI for information search. Was there a warrant in their hands for this? If not, that's privacy invasion and the search like that is considered illegal. Nobody else knows the reason on why is that happening like that but the enterprise customer being targeted is one of the rare cases Microsoft had discovered.
Eventually, Microsoft had won the court battle and in turn, the agency decided to withdraw information request. This is how Microsoft protects their users from illegal information request although the on-going battle against illegal cyber-surveillance is getting strong.
