I always appreciate how the US are able to pin every network compromise directly back to China. And not just China but the Chinese government in particular. Almost like VPNs, proxies, TOR, compromised machines, botnets, or similar do not exist in this arena and that a reverse DNS lookup will tell them 1337.mss.gov.cn.

Having hacked Google, Juniper, Symantic, Morgan Stanley and countless USGOV sites - why not hack NOAA? Its not as if there will be any USGOV response. No sanctions. No demarche of which I'm aware.
