The exhibit shows a pcap file capturing multiple TCP SYN packets directed at the same destination IP address.
High volume of SYN packets with very little variance in time: This pattern is indicative of a SYN flood attack, a type of Denial of Service (DoS) attack where numerous SYN requests are sent to overwhelm the target system.
SYN packets acknowledged from several source IP addresses: This can be indicative of a Distributed Denial of Service (DDoS) attack where multiple compromised hosts (botnet) are used to generate traffic.
These characteristics suggest that the network is under a SYN flood or DDoS attack, aiming to exhaust the target's resources and disrupt service availability.
