Tracking down these systems is easy, so these issues can normally be solved pretty easily. Thats because typically any amplification vector doesn't allow the source IP of the amplifier to be spoofed. So as soon as a DDoS attack begins, a sample of the packets can be taken to get a list of the amplifiers used. Those can then be tracked down and patched to no longer act as amplifiers.

#12Is it just me, or does it seem crazy that we all just accept that private businesses are obligated to protect themselves from state-sponsored hacking? Imagine if Wal-Mart had to fund a private air force and patrol over their stores in order to combat foreign bombers coming in and everyone was like, "Yeah, that's just how it goes." Isn't a primary responsibility of government to protect its citizens and businesses fro…

Just because nobody has figured out (or bothered to invest into) building the equivalent of basic security doesn't mean it's the state's responsibility.
It is the government's responsibility to make sure companies take their responsibilities of protecting their customers' data, and the internet more broadly from the impact of the company's decisions.

I guess it depends on the analogy, and whether physical location means anything for the internet. Piracy of commercial ships, for example.

unless the amplifier mechanism is widespread.

#18Earlier quoted context omitted.
because that value is a physical limit
How so? If I find a vector that triggers the remote system to `cat /dev/random | netcat $target` then there's no limit for how much traffic my refelection generates, no?

Dropping bombs on a walmart store is clearly unwelcome, sending traffic to walmart's website? Much less clear. You can guess based on the traffic pattern but the only way to really know is to ask walmart if this is welcome traffic (not just a burst because some new product came out). Especially since many cases are DoS with encrypted TLS traffic that looks much like any other traffic to an outside observer.
However much of the protection is threat of retaliation ("if you drop bombs on us we will flatten your country"). So maybe that is the solution here, the government should treat these attacks as real threats and punish those responsible.

Sorry but Walmart has cameras, guards, and most importantly locked windows and doors.
