Abstract
This is an update on "bitsquatting", a form of cybersquatting that exploits hardware bit-flip errors—often caused by cosmic rays or faulty components—during DNS requests. It explores how these random memory corruptions can inadvertently redirect legitimate network traffic to attacker-controlled domains that differ by only a single binary bit from the intended address. The briefing emphasizes the operational risks this vulnerability poses to security of the web, and the somewhat scary information leakage that occurs.
