Security researchers detail AirSnitch, a series of attacks that bypass Wi-Fi client isolation, enabling machine-in-the-middle attacks in modern Wi-Fi networks
That guest network you set up for your neighbors may not be as secure as you think. — It's hard to overstate the role that Wi-Fi plays in virtually every facet of life.

Trusting the conference/hotel Wi-Fi because client isolation is enabled? Think again. AirSnitch reveals severe flaws in wireless network implementations, bypassing protections to enable practical machine-in-the-middle attacks on other clients' traffic. https://www.ndss-symposium.…

Even when HTTPS is in place, an attacker can still intercept domain look-up traffic and use DNS cache poisoning to corrupt tables stored by the target's operating system. The AirSnitch MitM also puts the attacker in the position to wage attacks against vulnerabilities that may n…
