We will also show you a list with the best tools you can use to analyze websites and their hostings. Take a look to always be protected.
What kind of vulnerabilities can we detect by analyzing a domain and subdomain?
A Url address it’s divided in three parts, the first is the data transmission protocol, the second Y third is the domain and subdomain, respectively. As for the protocol it is necessary that one be of type HTTPS to prevent the vulnerability of communication between the device and the host being intercepted.
Regarding the domain and subdomain, you will be able to find different types of vulnerabilities, many related to the DNS server, which we present below:
- URL redirection: This mode of attack used by intruders is carried out through the Phishing, with which the victim is deceived by means of a graphical interface similar to that of the original site. In addition, a subdomain is created that was abandoned by the company, which owns the domain, to deceive people. The latter is what is known as subdomain ransom or subdomain takeover.
- XSS attacks: It is similar to the previous case, but this time the hackers malicious code is entered into the domain or subdomain so that it is executed by the person when they visit the page.
- Clickjacking: is generally used in Twitter and Facebook, and consists of redirecting the user to a page when he clicks on a link that is different from the one on the top-level website he wanted to go to. You will be able to know this technique through the analysis of the domain and subdomain that the reference button presents to you.
