[QUOTE="yitworths, post: 740639, member: 36772"] that's tricky. Randomization is dns specific, that is who has designed it, can tell you. Many dns responds to the different queries through same or predictable way. Those dns may fall victim to this kinda attack too early. Allow me to make it clear that every dns is vulnerable to this attack if you keep open the dns to respond to those queries for a long time. Luckily,we don't do that by nature. Lets say I'm targetting you, I have to keep a connection to your dns server for a long time. Now if your dns responds in a certain pattern & it doesn't change it . Then I can continue d attack after disconnecting & re-connecting to your dns & there won't be any loss on my part. But if your dns responds differntly everytime, man I have to be immortal to spoof your dns. May be. Eset is reputable av, they don't make garbage. But I can't ensure it will defend you against dns spoof attack. DNS spoofing much more complex than it may look. Have you ever seen a large scale DNS cache-poisoning attack in recent news? [/QUOTE]
