You may recall that I asked how the fuck the government had all this intimate knowledge of emails and private discussions among Megaupload personnel, given they weren't present in the US.

Turns out the feds are infecting people's computers with custom viruses in order to monitor them. Don't worry though, a judge approved it, so it's OK.

Also, the Chinese government hacking gmail? That was approved by their government as well, so no fair complaining about that.

The feds had a criminal subpoena and access to ALL of Megaupload's servers and emails from at least June 2010 to November 2011 - and Megaupload not only didn't remove anything, but continued using these servers during that period! (remember what I said about over-confidence).  Many of the details of this are in the indictment.

And they had their paypal & bank accounts via subpoenas.

And they seem to have informants in the company, who are referred to in the indictment as "non-indicted co-conspirators", and may have given the feds further electronic records.

Seeing as this is going to federal count, why would they gather inadmissible evidence (and use in the indictment), when they had admissible sources of all the info?
