SQL injection is a very popular and successful injection attack method. Identify the basic SQL injection text:
- AOption A:
‘ o 1=1 - -
- BOption B:
/../../../../
- COption C:
“DROPTABLE USERNAME”
- DOption D:
Show answer and explanation
Correct answer: A
Understanding SQL Injection Attacks:
SQL injection exploits vulnerabilities in an application’s interaction with a database by injecting malicious SQL code to manipulate queries.
About the Text ' or 1=1 --:
The input ' or 1=1 -- always evaluates to true (1=1) and the -- comments out the rest of the SQL statement.
This allows attackers to bypass authentication or extract unauthorized data.
Why Not Other Options:
B. /../../../../: Represents a directory traversal attack, not SQL injection.
C. " DROP TABLE USERNAME " : A destructive SQL command but not indicative of basic injection techniques.
D. NOPS: Refers to no-operation instructions used in buffer overflow attacks, not SQL injection.
EC-Council Guidance:
Recognizing and mitigating SQL injection is critical to securing database-driven applications, as emphasized in secure coding practices.
