Which type of exploit is being perpetrated? ✔✔Spoofing An attacker attempts to misdirect traf c on a network back to the attacker by corrupting the network computer's cache of IP address to MAC address mappings that are cached. Which exploit is the attacker perpetrating? ✔✔ARP(Address Resolution Protocol) poisoning Which exploit actually breaches the physical medium or uses devices to monitor signals from outside the physical medium itself? ✔✔Wiretapping Which type of attack can overwhelm a web server by inserting more data into a web form than the system was con gured to hold? ✔✔Buffer overflow Which type of attack sends an email claiming to be from a reputable business in order to entice the recipient to provide sensitive information? ✔✔Phishing A user on a network is planning to launch an exploit against a coworker in a neighboring department.
