almost anything is possible. I could either choose to build the hardware to try and hack into it, or I could become Batman. With enough cash, I could do both.
Consider this. This time they don't want to be as dumb as they were in the past when they let our nation's enemies have all the information they need about the attacks we were doing to them. In this case, once they find out exactly what it's doing and can determine if it's some retarded hacking team that wants to steal CC info or it's something the government's involved in. If it's the latter, there's no need to release info on who's being targeted and other specifics. They were probably also contacted in regards to what happened previously. Some countries feel a need to have some form of national security, regardless of what some bearded basement dweller thinks.
Of course there isn't anything to stop another country that finds code like this to setup something to let IT people do the work for them to tell them exactly what it does. In this case, if things go right, that country can then start setting up fake systems and start feeding bad info through the exploit.
