How to protect yourself from SQL injection attacks?
There are three main ways that organizations can protect themselves against SQL injection attacks: input validation, parameterized queries and access controls. Let’s explore each one of these.
Why did the Accellion SQL injection attack happen?
Experts speculate the Accellion attack was carried out by hackers with connections to the financial crimes group FIN11, and ransomware group Clop. The attack demonstrates that SQL injection is not just an attack that affects web applications or web services, but can also be used to compromise back-end systems and exfiltrate data.
How does SQL injection affect a web site?
While SQL Injection can affect any data-driven application that uses a SQL database, it is most often used to attack web sites. SQL Injection is a code injection technique that hackers can use to insert malicious SQL statements into input fields for execution by the underlying SQL database.
Which is the most common type of SQL injection?
You can classify SQL injections types based on the methods they use to access backend data and their damage potential. The attacker uses the same channel of communication to launch their attacks and to gather their results. In-band SQLi’s simplicity and efficiency make it one of the most common types of SQLi attack.
How are web frameworks used to prevent SQL injection?
In general, web frameworks prevent SQL injection attacks by providing easy methods of data querying so that developers aren’t seduced into writing hideously vulnerable SQL string concatenation statements. They perform two important tasks:
Do you need to know SQL injection for sysadmin?
But in order to understand injection/vulnerabilities, we need to take a step back and review that basic SQL knowledge first, which you may not have needed until this point in your role as a sysadmin.
Why is Union statement useful in SQL injection?
The UNION statement in particular is useful to a hacker because it allows him to splice the results of one query onto another. In this case, the hacker has spliced the names of the user tables in the database to the original query of the Products table. The only trick is to match the number and datatypes of the columns to the original query.
