 \n## Options:                             \n\nA-The hacker alters his approach and injects a 'DROP TABLE'statement,a move that couldpotentially lead to the loss of vital data stored in the application's database  \nB-The hacker tries to manipulate the 'UNION'keyword in such a way that it triggers a databaseerror,potentially revealing valuable information about the database's structure  \nC-The hacker switches tactics and resorts to a 'time-based blind'SQL Injection attack,whichwould force the application to delay its response,thereby revealing information based on theduration of the delay  \nD-The hacker attempts to bypass the special character filter by encoding his malicious input,which could potentially enable him to successfully inject damaging SQL queries  \n## Answer:\n\nD  \n## Explanation:\n\nSQL Injection is a type of attack that exploits a vulnerability in a web application that uses a SQLdatabase.The attacker injects malicious SQL code into the user input,such as a login form,thatis then executed by the database server.This can allow the attacker to access,modify,or deletedata,or execute commands on the database server.  \nThe 'UNION'SQL keyword is often used in SQL Injection attacks to combine the results of two ormore SELECT statements into a single result set.This can allow the attacker to retrieve additionaldata from other tables or columns that are not intended to be displayed by the application.Forexample,if the application uses the following query to check the user credentials:  \nSELECT*FROM users WHERE username ='$username'AND password ='$password'  \nThe attacker can inject a 'UNION'statement to append another query,such as:  \n'OR1=1 UNION SELECT*FROM credit_cards --  \nThis will result in the following query being executed by the database server:  \nSELECT*FROM users WHERE username=\"OR1=1 UNION SELECT*FROM credit_cards-'ANDpassword ='$password'  \nThe first part of the query will always return true,and the second part of the query willreturn thedata from the credit_cards table.The '--'symbol is a comment that will ignore the rest of thequery.The attacker can then see the credit card information in the application's response.  \nHowever,some web applications implement security measures to prevent SQL Injection attacks,such as filtering special characters in user inputs.Special characters are symbols that have aspecial meaning in SQL,such as quotes,semicolons,dashes,etc.By filtering or escaping thesecharacters,the application can prevent the attacker from injecting malicious SQL code.Forexample,if the application replaces single quotes with two single quotes,the previous injectionattempt will fail,as the query will become:  \nSELECT*FROM users WHERE username=\"\"OR1=1 UNION SELECT*FROM credit_cards--\"AND password ='$password'  \nThis will result in a syntax error,as the query is not valid SQL.  \nIn this challenging environment,if the hacker still intends to exploit this SQL Injection  \nvulnerability,the strategy that he is most likely to employ is to bypass the special character filterby encoding his malicious input.Encoding is a process of transforming data into a differentformat,such","cbCaithW17kYMTo8","https://ap.wps.com/l/cbCaithW17kYMTo8","pdf",246001,"English","# Free Questions for 312-50\n## Options\n## Answer\n## Explanation\n## Question 2","[{\"question\":\"Which SQL Injection strategy best bypasses a special-character filter?\",\"answer\":\"Encode the malicious input so the application filter fails and the database receives the decoded payload.\"},{\"question\":\"What does UNION do in SQL Injection attacks?\",\"answer\":\"It combines results of multiple SELECT statements into a single result set, enabling retrieval of additional data.\"},{\"question\":\"Why can error-based SQL Injection be effective during audits?\",\"answer\":\"Because detailed error messages reveal underlying database structure, allowing information disclosure and potential enumeration.\"}]","312-50 Free Questions - SQL Injection Exam Practice | PDF",1788335641,23]
