The list goes on and on, and the ip's in the last fifty lines were all Chinese or Russian, still they could also have been hacked themselves.
Of course, this is a whole different level of culpability than if they were actually condoning large scale attacks on other countries infrastructure.
The fact remains that if I were to plot the amount of ip's that come knocking at my non-production server you'd see over 50% coming from china.
17.18% of all desktop OS-es connected to the internet are Windows XP, the version for which Microsoft doesn't publish updates. Most of these computers are in China. Also "in 2009, approximately 80% of software sold in China was pirated."
The average weekly income of a Chinese worker is around 100 USD. He is not going to buy new software even if it costs the same as in the US. It typically costs even more.
Don't be surprised bots have easier targets there.
Hint: port 9415
1) use a different port 2) use ip ban 3) use a firewall with range blocking -
Or do you have a good reason for allowing access from every ip on the internet?
EDIT: removed snark
If it were me, I'd just issue a formal letter thanking the Chinese government and their people for spending their own taxpayer's money pen-testing U.S. infrastructure and ensuring security best practices are followed ;p (yes, I am being tongue-in-cheek, speaking of cheeks...)
I find it weird how in a world this connected, we still only get one POV.
The "one POV" thing is not about how interconnected the world is; it's about language barrier. An English site will always be dominated by people whose native language is English.
So yes, probably.
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.
When the US talk about cybersecurity/"cyber wars" in general they're talking about something more akin to a Hollywood movie than anything you see on the ground on either side of the "fight."
I'm extremely sceptical every time they claim Chinese responsibility. I am sceptical not because China wouldn't have the skills or motivation to do so (they do/would) but because they jump to these conclusions unrealistically quickly and if their adversary covered their tracks even modestly pointing fingers like that would be quite hard (e.g. send it through Russia).
