DEFCON 19: Bit-squatting: DNS Hijacking Without Exploitation (w speaker)
Christiaan008
Artem Dinaburg's DEF CON 19 talk on bit-squatting, where flipped bits in DRAM cause devices to contact domains that differ by one bit from legitimate ones. He shows how registering such domains can hijack traffic without exploiting any software bug.
HN cites it in ECC memory debates and bit-flip discussions as concrete evidence that memory errors have real security consequences.
