Phishing attacks happen through email. These emails could contain malicious attachments or malicious links which when clicked on, steal sensitive data like credit card detail/logging information or might install malicious software.
Man-in-the-middle attack
This attack interrupts a transaction between clients and the server, steal the data, and modify if wanted.
Denial-of -service attack
Here, the attacker usually sends excessive messages asking the network or server to authenticate requests that have invalid return addresses. The main purpose of a DoS attack is not to steal information but to slow or take down a web site.
SQL injection
In a SQL Injection attack, the attacker uses a code injection query to steal your database information. The query is used to inject malicious code to the web page input and steals sensitive data such as logging information and can also modify data.
Zero-day exploit
This attack happens when network vulnerability is exposed. The attacker targets the disclosed vulnerability before the system is patched and the solution is implemented.
