Given the following code, answer the questions.     a) Analyze each part of the code and explain the present weaknesses (10 points).   b) Rewrite or describe how to modify the code to fix the previous weakness (10 points).  

A security analyst is investigating a recent incident at a small e-commerce company. The analyst has gathered the following information: Initial Observation: An employee received an email with a malicious PDF attachment disguised as an invoice. Action: The employee opened the PDF, which exploited a known vulnerability in their PDF reader software. Result: The exploit allowed the attacker to install a remote access tool on the employee’s computer. Further Action: The attacker then used the remote access tool to move laterally within the network, eventually gaining access to the company’s customer database server. In which phase of the Cyber Kill Chain did the employee opening the malicious PDF attachment occur?

SQL injection is a common vulnerability allowing attackers to manipulate a database by injecting malicious SQL code into input fields. Below is a piece of JavaScript code that interacts with a MySQL database using user input. Unfortunately, this code is vulnerable to SQL injection.     Database Name: user_database Tables: users (columns: id, username, password) admin_logs (columns: log_id, admin_action, timestamp)   Question: Explain why the provided JavaScript code is vulnerable to SQL injection. Describe the specific part of the code that leads to this vulnerability (It is required to cite how the exploitation happens line-by-line) (10 points).   Provide an example of a malicious input that an attacker could send to the /getUser endpoint to retrieve all entries from the admin_logs table (the input must work) (10 points).  

Importing and Using a Function from a Library Write a Python code snippet that imports the sqrt function from the math library and uses it to compute the square root of 16.

In NumPy, the function np.arange(start, stop, step) generates an array with [answer] spaced values.

Accessing Nested Data Structures Given the following list of dictionaries where each dictionary contains a key “name” and a key “grades” (which is a list of integers), write a Python code snippet to access and print the second grade of the dictionary where “name” is “Alice”. students = [                 {“name”: “Alice”, “grades”: [90, 85, 92]},                 {“name”: “Bob”, “grades”: [75, 80, 78]}  ]
