How to Avoid Being Redirected to Malicious Sites

http-redirectionWhenever we surf the Internet we run the risk of suffering different types of attacks. We can be victims of very diverse threats that put our security and privacy at risk. In this article we are going to focus on web redirection. It is a very important problem and it can affect at any time. We will explain how they could redirect us to malicious websites and what to do to avoid it.



The danger of entering a malicious page

We must bear in mind that when surfing the Internet , simply entering a website, we can be victims of very varied attacks. Our teams can be compromised through techniques used by hackers to carry out their attacks.

All this makes it necessary to have the right tools and use common sense. We need to protect our devices and avoid excessive exposure that affects our privacy. We already know that currently the information and data of users have great value in the network. This makes them look for ways to obtain that information through different methods.

One of the techniques that cybercriminals use to attack us when surfing is through malicious pages. They redirect us through fraudulent links so that we arrive at a site that has been modified to carry out data theft or show us malicious software.

How they redirect us to malicious pages

Hackers can use different techniques to get us to a malicious page. We could even enter a legitimate page but it has suffered an attack and actually has malicious code in order to steal information.

Update headers and meta tags

A web page can be modified in different ways through HTML . We can add content, functions … Something that many web developers use is the possibility of using the update headers and meta tags to redirect content. It is legitimate, but it can be used for malicious purposes.

For example, we could enter a website where it welcomes us and after a few seconds it takes us to another page where we already see the content. But of course, the same can be used by hackers to carry out their attacks. Basically they modify this code so that once the user enters the site they are redirected to another controlled by the attacker.

JavaScript Injection

Another technique used by hackers is to inject JavaScript code . Being able to inject code could redirect to any other URL. This would give you user control.

This can happen through add-ons, for example. It may include malicious JavaScript that actually has the objective of redirecting us to a fraudulent site. Sometimes the JavaScript code may not be detected by security tools.

Security holes in add-ons to redirect

There are add-ons designed to redirect sites . This is very useful on certain occasions for users to go to another page, another service or platform they offer, for example.

However, these accessories may have security holes. They could be used by hackers to modify them and take the victim to a page controlled by them.

Similar links

Undoubtedly something widely used by cybercriminals is the use of similar links. We talk about sending by email or social networks, for example, links that lead to pages that are apparently similar but in reality they are not. It basically means that we are going to enter a link that pretends to be legitimate but we are going to a malicious page.

How to avoid page redirection

Keep in mind that we must take care of this both at the user level and also when we have a web page. It is important to always have updated systems and add-ons . We have seen that sometimes they can inject code through existing vulnerabilities. Therefore it will be vital to always have the latest versions.

Common sense is essential at the user level. We must always observe the URL we are entering, take care of possible fraudulent links, etc. It can rid us of important problems. Be sure to always enter HTTPS pages.

It may also be interesting to use security tools . They could help us to detect very varied threats that affect the proper functioning of the system and, ultimately, our security and privacy.
