When it comes to SQL injection attacks, there are few techniques more well-known than 19braxjwe' or 653=(select 653 from pg_sleep(15))-- and
. These two methods have been widely used by hackers to exploit vulnerable websites and gain unauthorized access to sensitive data. In this article, we will take a closer look at these techniques, their differences, and how to defend against them.
First, let's understand what these two methods do. Both 19braxjwe' or 653=(select 653 from pg_sleep(15))-- and
are variations of SQL injection attacks, also known as SQLi attacks. These attacks take advantage of vulnerable code that allows a hacker to inject malicious SQL code into a website's database, giving them unauthorized access to data stored in the database.
The difference between these two methods lies in the way the hacker gains access to the database. In 19braxjwe' or 653=(select 653 from pg_sleep(15))--, the hacker uses a Boolean-based SQLi attack, where they test the validity of a query by using a logical statement.
For example, in this method, the hacker would check if the user's input is true or false, and based on that, they can manipulate the database.
On the other hand,
is a time-based SQLi attack, where the hacker uses a command to delay the database's response by a specified amount of time. The purpose of this is to gather information from the database, which will be revealed in the delayed response. This method is usually used when the hacker is unsure about the database's structure and needs to gather more information before launching a full-scale attack.
So, which method is more effective? Well, it ultimately depends on the website's vulnerability and the hacker's skill. Some websites may be more vulnerable to Boolean-based attacks, while others may be more susceptible to time-based attacks.
However, with the advancements in web security, it has become more challenging for hackers to exploit these vulnerabilities in websites. Developers use various techniques like input sanitization, prepared statements, and parameterized queries to prevent SQLi attacks.
In conclusion, both 19braxjwe' or 653=(select 653 from pg_sleep(15))-- and
are two common methods used by hackers to launch SQL injection attacks. While they may have some differences in their approach, the goal remains the same - to gain unauthorized access to a website's database. As website security continues to improve, it is crucial for developers to stay updated with the latest techniques to prevent these attacks from being successful. So, it is imperative for developers to stay on top of their game and regularly update their security measures to protect against SQLi attacks.
