The security community is also steadily addressing the linchpin to all the assaults: the vulnerable memcached servers. About 100,000 of these online storage systems were publicly exposed over a week ago. But the server owners have since patched or firewalled about 60,000 of them, Radware security researcher Daniel Smith said. That leaves 40,000 servers open to exploitation. Smith points to how the coding behind the attack technique has started to circulate online through free tools and scripts.
Meanwhile, Slashdot reader darthcamaro shares an article about "the so-call 'kill switch'" that some vendors have been debating: "The 'kill switch' was immediately obvious to everyone who worked on mitigating this DDoS attack," John Graham-Cumming, CTO of CloudFlare said. "We chose not to use or test this method because it would be unethical and likely illegal since it alters the state of a remote machine without authorization."
