3) If it was that easy to do, why hasn't it happened again?because that particular attack only works if you are willing to get caught.
Nicely put. Although accidents do happen, like the genieweb.com answering for ".com" debacle a couple weeks back.
4) How can I check for cache corruption?"dig @0 www.netsol.com a" and "dig @cache00.ns.uu.net www.netsol.com a" and check for differences.
Paul: I assume dig @0 is an idiom for localhost? (Apologies for being less than familiar with dig, it's not on this machine, and I'm not the admin.)
Apologies if any of the above sound moronic or ill-informed; extracting facts from reams of "what is a backhoe" mail list is a painfully slow task. Time for some filters I think...no apologia needed. public explainations of this attack have been poor, even and especially by me. i'm grateful for the opportunity to improve on that.
I hadn't thought that the explanations were all _that_ weak... and I'm on 7 lists, and the backhoe traffic didn't bother _me_ that much. Perhaps time for a new mail program, or a faster link?
