Conducted in Tel Aviv, the researcher’s experiment showed just how easy an attacker could hack into home and enterprise networks, by simply walking around a city with the right equipment in hand.

For his experiment, CyberArk’s Ido Hoorvitch used an AWUS036ACH ALFA Network card, which costs around $50, and provides both monitoring and packet injection capabilities, connected it to an Ubuntu system, and walked around the center of Tel Aviv with the system in a backpack, to sniff Wi-Fi networks.

For his research, Hoorvitch was interested in capturing the PMKID hash from the Wi-Fi networks, and he used Hcxdumptool, a utility by ZerBea, for that.
