On city hall guest Wi-Fi, several browsers suddenly warn about unexpected certificates and session contents appear altered mid-transfer. Which attack indicator does this describe?
Select an answer to reveal the explanation.
Short Explanation
Weird certs and tweaked traffic on open Wi-Fi usually means someone sat in the path. On-path (MITM) attackers proxy the session so they can watch or change what you think is private.
Full Explanation
On-path attacks intercept communications between endpoints, often producing certificate warnings when certificates are substituted and enabling alteration of session traffic. Logic bombs, worm spread, and encryption of backup media do not explain unexpected cert warnings and altered wireless sessions on guest Wi-Fi.
