This event category is exploitation because the HTTP requests contain PHP code that attempts to execute commands on the web server and create a backdoor. Exploitation is the phase of the attack where the threat actor gains access to the target system and executes malicious code. References: https://learningnetworkstore.cisco.com/on-demand-e-learning/understanding-cisco-cybersecurity-operations-fundamentals-cbrops-v1-0/CSCU-LP-CBROPS-V1-028093.html (Module 2, Lesson 2.1.3)

Stealthwatch is the technology that an engineer should use to fetch logs from a proxy server and generate actual events based on the data received. Cisco Secure Network Analytics, formerly known as Stealthwatch, provides the capability to configure proxy server logs so that the Flow Collector can receive the information. The Stealthwatch Management Console then displays this information on the Flow Proxy Records page, which includes URLs and application names of the traffic inside a network going through the proxy server1.

The lack of data visibility needed to detect the attack is caused by the threat actor gaining access to the system by known credentials. This means that the threat actor either obtained the employee’s username and password through phishing, social engineering, or other means, or used a compromised account that had legitimate access to the system. This would explain why there were no suspicious logs, alerts, or failed login attempts, as the threat actor appeared to be a normal user. References: https://learningnetworkstore.cisco.com/on-demand-e-learning/understanding-cisco-cybersecurity-operations-fundamentals-cbrops-v1-0/CSCU-LP-CBROPS-V1-028093.html (Module 2, Lesson 2.1.2)
