The technique of SQL injection started around 1990??s. SQL stands for Structured Query Language. It was first used for attacking a secure website by injecting SQL codes into the web application form. On doing so, it use to spoil the design of website. Moreover, later many started using it to crack database contents by bypass authentication. Most hackers learn this technique as it lets them break through the website security and perform data theft. However, things are not the same now, today lot of advances have gone through the security point of view of a website. Following you will find a summary on all techniques related to SQL injection covered from the period of 90??s till today.
An SQL injection works towards efficiently exploiting web application information through bypassing its authentication credentials. ?In most cases, a web application requires login to application prior to getting an access to the secured information. Whenever a user tries performing login action, then he/she is actually transmitting information such as username along with passwords. A web application or control panel receives this sensitized information to further process the command. However, if the user is unauthorized then he/she receives a failure tag, and needs to re-login with correct credentials as stored inside the database. Here is when the user tries to use SQL injection technique to rescue the login credentials of a person for making website accessible to him/her.
A traditional way to check if it is possible to attack a website with SQL injection is by simply placing a single inverted comma after the URL tag of the website. If the website shows an error such as ??not found?? then it may be protected from SQL injection. However, if you find the URL redirecting to parking pages showing crack in codes, then it means you can hack it.
On finding whether a website is free to hack, the hacker tries to steal databases, by login into the system with a list of usernames. However, you may find it surprising to know how the hacker knows the password of each usernames. The trick he/she plays is quite simple. Using SQL injection he/she simply enters the code such as ??1??=??1?? after the username and password tag. The above script is a logical condition assigned for true values. Hence, whenever a hacker using SQL injection injects a code with username, placing above code, any desired password would make him/her accessible to the user account. This happens owing to the logical condition manipulation. Hence, it is quite easy to dodge information from website database using SQL injection.
This traditional technique was followed over years until developers became aware of them. They decided to join a joint venture by building additional secure technologies. The terror of SQL injection continued till late decade after its launch, making it one of the most effective website hacking techniques. Apart from bypassing data and malicious injections, SQL injection found more use in information leakage. Modern hackers make use of new techniques to hack a website and thieve sensitive data.
Without doubt, reforms for exploring new techniques are still going on in this field. You must have heard about the latest Denial-of-Service or DDoS tools, which extends the vulnerabilities of an SQL attack. These new advancement have brought down the whole of web application technologies to its knees.
Today, it has been more than two decades and yet you can feel the magnitude of impact that it had once left its foot mark on. No wonder that hackers are still occupied in bringing new modification in this traditional technology to further reinforce it. An ideal way to protect yourself from modern SQL injection such as DDoS and other counterpart vector elements is by choosing firewall securities. WAF or Web Application Firewall finds its use in disappointing hackers using SQL injection methods. Some adept software such as BIG-IP ASM are gaining foothold to resist attackers. However, on the contrary, hackers too are developing new ways of attacking the web application interfaces.
Conclusion:
The potentials for SQL injection are high similar to it was once upon a time two decade ago from now. Indeed new methods such as WAF were game changers that stopped mass hacking, which was once rampant. However, advance competition between SQL injection hackers and firewall securities keeps the subject still hot. There is no harm in concluding that the war between hackers and security analyst has just got better. Interestingly, SQL injection even after 20 years holds same level of excitement for a hacker, which it once did.
