Refer to the exhibit. An engineer is analyzing a PCAP file after a recent breach. An engineer identified that the attacker used an aggressive ARP scan to scan the hosts and found web and SSH servers. Further analysis showed several SSH Server Banner and Key Exchange Initiations. The engineer cannot see the exact data being transmitted over an encrypted channel and cannot identify how the attacker gained access. How did the attacker gain access?
