The #netstat -an command output typically displays a list of all open ports and associated connections. If the web application is slowed down, the engineer would look for unusual patterns such as an excessive number of connections to the web server which could indicate a denial-of-service attack. However, without specific details from the #netstat -an output, it’s not possible to determine the exact cause of the issue. Therefore, the engineer would need to gather more data, possibly including checking server logs, resource usage, and network traffic patterns to diagnose the problem accurately.

 Cyber attribution is the process of identifying the source, motive, and methods of a cyberattack. Cyber attribution can help investigators to determine the responsibility, intent, and capability of the threat actors, as well as to prevent, deter, or respond to future attacks. One of the pieces of information that is needed for cyber attribution is known threat actor behavior, which refers to the patterns, techniques, tools, and tactics that are characteristic of a specific threat actor or group. Known threat actor behavior can help investigators to narrow down the suspects, link different incidents, and understand the objectives and strategies of the attackers. References := Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) v1.0, Module 5: Security Policies and Procedures, Lesson 5.2: Incident Response, Topic 5.2.3: Cyber Attribution, page 5-14.

• The Cuckoo sandbox report shows the analysis results of a file named "VirusShare_fc1937c1aa536b3744ebfb1716fd5f4d".
• The file type is identified as a PE32 executable for MS Windows.
• The "Yara" section indicates that the file contains shellcode, which matches specific shellcode byte patterns.
• Shellcode typically indicates that the file will execute a payload, often used to open a command interpreter or execute commands directly.
• Additionally, the antivirus result shows that the file was identified as containing a trojan (Trojan.Generic.7654828), which is consistent with behaviors such as opening a command interpreter for malicious purposes.

The exhibit shows a SQL query that is attempting to bypass login controls by modifying the query to always return true. This is a common tactic used in SQL injection attacks where malicious SQL statements are inserted into an entry field for execution. References := Cisco Cybersecurity Source Documents
