An injection attack is the one of the most preferred methods by cybercriminals because there are numerous ways to do it. It can be used in small- and large-scale breaches, and it is complex to defend against. An injection attack is named so because it is conducted by injecting data into a web application, which hackers use to steal or manipulate information.

The following are the most common injection attacks:
SQL Injection
SQL, which means structured query language, is a programming language needed to manage data and communicate with databases. An SQL injection introduces malicious codes into a database, which gives hackers access to stored information, such as private company and customer records. There are SQL injection attacks that can grant perpetrators administration rights, letting them gain control of the web application.
Code Injection
Also called remote file inclusion, cyber-attackers use code injection to target weaknesses in web applications caused by the processing of invalid data. This allows hackers to upload malware in the system, giving them access to data or allowing them to take over the system.
Log File Injection
Web applications use a range of log files to record events and transactions that owners can use to compile statistics. It can also be used for debugging, if needed. However, there can be vulnerabilities in these log files that hackers could exploit by injecting malicious content in them.
