Visiting a malicious website can be one of the worst things that can happen to people who surf the Internet, especially those who are interested in shopping online. Webmasters need to know the threats to websites and their devastating capabilities – losing customers is the first thing to do.

It is profitable for hackers to steal information from individuals and use it for personal purposes. Profits can be monetary or abstract. While hacking, phishing and social engineering are common methods, hackers also use other people’s websites to compromise users’ computers and access their data. The following picture gives you an idea of the threats to your website.

It is therefore the webmaster’s responsibility to ensure that his website is free of malicious code and vulnerabilities. This is not an easy task, since there can be thousands of pages and the hacker selectively inserts the code on some pages. Since this is about your reputation, you have to do it. Fortunately, there are tools that can scan your websites daily to report on infectious code and vulnerabilities (such as login screens, forms, etc.).

In addition, browsers and browser plug-ins are available that trigger an alarm when you visit a malicious and infected website. Although you have visited this site before and it is hard for you to believe that a site you trust is infected, it can be really malicious without the webmaster knowing – because an hour ago, a hacker added code to the site.

With regard to worst-case scenarios – or the threat capabilities of websites – there are two major aspects to damage :

  1. Webmasters may lose customers because the browser triggers an alert when visitors try to visit their site; Google, etc. Search engines can blacklist the site if they find malicious code while browsing the site.
  2. On the user’s side, the user’s computer and therefore his data are in danger and can lead to identity theft.

Common types of threats on websites

The most common and best known is clickjacking. With this method, there is a transparent layer of malicious code on a button or video. Click the button to download the code to your computer. You may have seen similar methods for advertising on C-quality websites, mainly in connection with piracy and pornography, etc.

Web site redirection vulnerabilities allow hackers to use redirects for their profits. You can intercept the exchanged data or use redirection to redirect users to a phishing site.

Other types of Web site threats include targeted attacks with pre-built operating kits that are readily available on the Internet. These kits allow hackers to attack certain (types of) websites and add malicious links. Another method is to send malicious link emails to the site that bypass the unsuspecting webmaster to turn it into a malicious site.

Recent attacks on popular websites show that even the largest websites are vulnerable. People who have lost their access data will probably not return to the website.

Imagine your business or your e-commerce site on the blacklist and you stay in the dark for weeks until search engines put it back on the white list. Although the process of removing a website from blacklists is difficult, can your business survive if it is not in public view for weeks?

Encryption : Use a secure connection for everything users do on your site, especially when they are involved in transactions.

Upgrade to EV SSL: Do this anywhere on the site where the customer can enter data
