69. What type of vulnerability do SQL injection attacks exploit?

SQL injection attacks exploit vulnerabilities in the application’s interaction with the database, not the database itself.

70. What languages and protocols are used in building a website and sending queries to a database?

For functionality, websites are built using HTML, JavaScripting, cascading style sheets, React, and JS.

Queries are typically sent to the website using the HTTP or HTTPS protocol, and on the client side, scripting languages are used to craft questions and send them across.

On the server side, databases like Oracle, MySQL, and MS SQL execute these queries.

71. What is the role of time waiting in a time-basedSQL injection attack?

In a time-based sequence injection attack, the time wait refers to the delay between the execution of the SQL command and the response from the database.

If the query executes within this time wait, it may indicate that the SQL injection is possible.

72. How doyou prevent SQL injection attacks in a database system?

To prevent SQL injection attacks, it is crucial to ensure that queries are executed at a user level with minimum privileges and that administrative accounts can access only necessary functions.

Proper validation and sanitisation of user input and regular security updates and patches can also help prevent SQL injection attacks.

A phishing attack is a type of social engineering where fraudulent messages are sent to a target, assuming they come from a trusted source.

The goal is to trick the victim into revealing sensitive information, such as passwords and payment details.

74. What are the different types of phishing attacks?

Phishing attacks can be classified into deceptive, spear phishing, and farming.

Deceptive phishing involves general emails sent to thousands of users, while spear phishing is customised, and targets are researched before being sent to an email.

Farming focuses on fake websites that resemble their original counterparts.

75. What is cross-site scripting (XSS), and how does it occur?

Cross-site scripting (XSS) is a code injection attack that allows attackers to embed malicious code or scripts into a genuine web page or online application.

The attack occurs when a victim visits the malicious web page or interacts with the infected application.

JavaScript is commonly used for XSS attacks due to its ability to add functionality and interactivity to web pages.

76. How does an error-based SQL injection attack work?

In an error-based SQL injection attack, a single quote operator selects the default table in the user tables and compares it to a given condition.

If the condition is false, the account doesn’t exist and is re-created.

If the condition is forgotten, an error is generated, indicating an error in the SQL syntax.

77. What is the best way to prevent becoming a victim of phishing attacks?

To prevent becoming a victim of phishing attacks, it is crucial to check the authenticity of links in emails and redirect them to secure websites running on HTTPS protocol.

Suspicious messages should not be entertained, and private information should not be entered on random websites or pop-up windows.

Secure anti-phishing browser extensions like Clownfish can help sniff out malicious emails from legitimate ones.

78. What can attackers do with cross-site scripting?

Attackers can use cross-site scripting to add unwanted spam content to a web page, gather analytics about the client’s browser, perform actions asynchronously, capture user keystrokes, redirect victims to malicious websites, run web browser-based exploits, obtain cookie information, and even compromise the victim’s account.

79. What other damage can Phishing attacks cause?

Some phishing campaigns also target the victim’s device and install malware when clicking malicious links.

This malware can later function as a botnet or target for ransomware attacks.

80. What is the difference between Stored and Reflected attacks in XSS?

Stored attacks occur when a malicious script is saved on the web server permanently, allowing more damage to be done.

On the other hand, reflected attacks happen when a malicious script is not held on the server but is reflected in the website results.
