2. SQL Injection (SQLi) Attacks

What is SQL Injection?

SQL Injection (SQLi) is a code injection attack where cybercriminals manipulate a website’s database by inserting malicious SQL statements into input fields. This technique allows attackers to bypass authentication, extract sensitive data, modify or delete database records, and, in some cases, gain full control of the server.

Once an attacker exploits an SQLi vulnerability, they can:

  • Steal confidential data (e.g., usernames, passwords, financial records).
  • Manipulate database contents, altering or deleting critical information.
  • Take control of the entire system, leading to business disruption.
  • Execute administrative operations, such as creating new unauthorized user accounts.

How SQL Injection Works

SQLi attacks exploit vulnerabilities in web applications that fail to properly sanitize user inputs. When a website does not validate or escape special characters in SQL queries, attackers can insert malicious SQL commands into input fields.

Common entry points include:

  • Login forms
  • Search bars
  • Contact forms
  • URL parameters

SQL Injection remains a top security risk, continually exploited by cybercriminals due to its simplicity and effectiveness.

3. Phishing and Social Engineering Threats

In today’s digital landscape, phishing, and social engineering attacks are among the most deceptive cyber threats, targeting website owners and users. Unlike direct hacking attempts, these attacks manipulate human psychology to steal credentials, financial data, and other sensitive information. 

What is Phishing and Social Engineering?

Phishing and social engineering involve fraudulent techniques used to deceive individuals into revealing confidential data. Once successful, these attacks can:

  • Steal login credentials and compromise accounts.
