Web attacks are cyberattacks that target web sites, web applications and web servers. There are many types of web attacks. Each type has its own method and purpose. Here are some of the most common web attacks:
- SQL injection: An attacker injects malicious code to a website’s Structured Query Language database (SQL). This can be done by manipulating input fields on a website, such as search bars or login forms, to execute unauthorized SQL commands and gain access to sensitive information stored within the database.
- Cross-site scripting: XSS attacks are when malicious code is infected into a website, most often as a script. The victim’s web browser executes the injected code, which allows the attacker to steal sensitive data or do other malicious acts. There are two types of XSS attacks. Non-persistent attacks last for a short time and require victims to click on a link to access the compromised website to execute the infected code. Persistent attacks are more persistent and can continue even after the victim leaves the compromised website.
- Cross-site request fraud (CSRF: CSRF attacks are a way to trick the victim into performing an unintended act on a website. The attacker sends a malicious request to a website the victim has already authenticated to. An attacker may send a link to a victim claiming to be from their bank. However, when the victim clicks the link it triggers a transfer from their account to the attacker.
- Distributed denial of services (DDoS), and DoS (denial of service) attacks: DoS or DDoS attacks are attempts to overwhelm a website with traffic and make it unusable for legitimate users. DoS attacks are usually carried out by one attacker. DDoS attacks involve several attackers working together to flood the target site with traffic.
- Phishing is a technique that tricks victims into giving sensitive information such as login credentials and financial information. The attacker pretends to be a legitimate source. The attacker can use various tactics to appear legitimate. For example, he may create fake websites or use logos and branding of reputable companies.
- Man-in the-middle attacks (MitM): MitM attacks are when an attacker intercepts communication between two parties to gain access or manipulate sensitive information. You can do this by setting up a fake Wi Fi hotspot, or intercepting traffic on the shared network.
- Password attacks: Password attack is a way to gain access to an account or system by cracking or guessing the password. There are many types of password attacks: dictionary attacks, brute force, rainbow table, and more.
Website owners and users need to be aware that these kinds of attacks can occur and take precautions to avoid them. You can implement security measures like strong passwords, two factor authentication, regular software updates, and educate users about the best practices to stay safe online.
