The penetration tester's discovery of passwords vulnerable to hash cracking suggests a lack of robust password policies within the organization. Among the options provided, implementing a blocklist of known bad passwords is the most effective immediate remediation. This measure would prevent users from setting passwords that are easily guessable or commonly used, which are susceptible to hash cracking tools like Hashcat.

Requiring passwords to follow complexity rules (Option A) can be helpful, but attackers can still crack complex passwords if they are common or have been exposed in previous breaches. Setting a minimum password length (Option C) is a good practice, but length alone does not ensure a password's strength against hash cracking techniques. Encrypting passwords with a stronger algorithm (Option D) is a valid long-term strategy but would not prevent users from choosing weak passwords that could be easily guessed before hash cracking is even necessary.

Therefore, a blocklist addresses the specific vulnerability exposed by the penetration tester—users setting weak passwords that can be easily cracked. It's also worth noting that the best practice is a combination of strong, enforced password policies, user education, and the use of multi-factor authentication to enhance security further.

The error message "Unclosed quotation mark after the character string Incorrect syntax near '." suggests that the application is vulnerable to SQL Injection (A). This type of vulnerability occurs when an attacker is able to inject malicious SQL queries into an application's database query. The error message indicates that the application's input handling allows for the manipulation of the underlying SQL queries, which can lead to unauthorized data access, data modification, and other database-related attacks.

The payload used by the penetration tester is a type of blind SQL injection attack that delays the response of the database by 15 seconds if the condition is true. This can be used to extract information from the database by asking a series of true or false questions. To prevent this type of attack, the best practice is to use parameterized queries, which separate the user input from the SQL statement and prevent the injection of malicious code. Encrypting passwords, encoding output, and sanitizing HTML are also good security measures, but they do not directly address the SQL injection vulnerability. References:

The most efficient way to write a Python script that interacts with web applications is to import the requests library. The requests library is a Python HTTP library that simplifies making HTTP requests to web servers, which is essential for interacting with web applications. It allows you to easily send HTTP/1.1 requests, without the need for manually adding query strings to your URLs, or form-encode your POST data. Options A and B involve creating a class or function for requests, which could be more time-consuming and less efficient than using a well-established library like requests. Option D, using the cURL OS command, is less efficient in a Python script since it involves calling an external command rather than using a native Python library.
