Bruce Shneier, the well known security expert disclosed that the big brand internet infrastructure provider have seen hike in DDoS attacks against them.

As per the Schneier’s guesses, “The data I see suggests China, an assessment shared by the people I spoke with. On the other hand, it's possible to disguise the country of origin for these sorts of attacks.”

“The NSA, which has more surveillance in the Internet backbone than everyone else combined, probably has a better idea, but unless the US decides to make an international incident over this, we won't see any attribution.”as he further added.
