Explanation:
Exploitation - The targeted Environment is taken advantage of triggering the threat actor's code Installation - Backdoor is placed on the victim system allowing the threat actor to maintain the persistence.
Command and Control - An outbound connection is established to an Internet-based controller server.
Actions and Objectives - The threat actor takes actions to violate data integrity and availability

TCP injection is an attack where the attacker sends crafted packets into an existing TCP session. These packets appear to be part of the session.
The presence of many SYN packets with the same sequence number, source, and destination IP but different payloads indicates that an attacker might be injecting packets into the session.
This method can be used to disrupt communication, inject malicious commands, or manipulate the data being transmitted.

The PCAP file in the exhibit shows a Transmission Control Protocol (TCP) communication between two IP addresses. In the data section of the packet capture, "pdy/3.1... http/1" isvisible, indicating that HTTP (Hypertext Transfer Protocol) is being used as the application protocol for this communication.
