Why did they do it in a way to weakness

Anonymous, the informal hacker collective, it has been gotten  some ass kicked.
The latest attack was planned to in North Korea, to coincide with the anniversary of the Korean War, on Tuesday. From what outside analysts can tell, though, Anonymous doesn’t seem to have accomplished these goals.
Yes, they got no nothing, but loss of their face.

The failed hacks are a reminder that North Korea has demonstrated, against all odds, its remarkable ability to seal itself off from a world very, very eager to peer in.
According to Washington Post this doesn’t just include hacker collectives like Anonymous: it’s not hard to find current and former U.S. intelligence officials who concede that they have very little solid information about its inner workings. Partly this is about North Korea’s better-than-you-might think.
Yes, but I know that they, U.S. intelligence officials what_ever, have enough knowledge about this tyranny.
But i did not know that the great Anonymous can be just this kind of an amateur goup level.
