About Suspicious Domain Checker

Learning to surf the Internet safely should be a vital skill for any web user. Hackers and scammers are continuously developing new methods of stealing your identity, data or money. If you thought malware only comes from devious, shady sites, you are in for a shock. These Hackers routinely upload malware to smaller, legitimate websites with the intention of carrying out malicious activity against a website or it's visitors. They generally target poorly protected sites for any number of malicious reasons ranging from sending phishing emails or to run DDoS attacks.

Website malware is a harmful software that has been developed to steal sensitive user data without their consent. Given the huge volume of services and web apps available on the web, it’s not surprising that the popularity of these applications also attracts cybercriminals hoping to leverage weak security or known vulnerabilities to their advantage.

If you are an online business, your valuable visitors and customers need to be absolutely certain that they are safe when using your website. This means that it is your responsibility to make sure that they are protected from any malware and dangerous online viruses, as well as a host of other threats.

What is Website Malware?

Website malware is a software that has been developed with a malicious intent of stealing data or personal information on a website or web server. An infected website contains malicious code in the form of HTML that manipulates the browser to perform illegal actions. This malicious code is usually placed in the interactive, inline iframe that is used by browsers to embed an HTML document within another HTML document.

An iframe is an attractive way to place these codes because it can execute JavaScript. Thi is because, an iframe can be sized to be 0×0 so that it effectively isn’t displayed while doing shady things. When used for downloads, it's primary use is to redirect a user from any page to a malicious page hosting a BEP.

The aims of malicious website code can range from stealing sensitive information, disrupting availability, hijacking a website, redirecting visitors to spam pages, or even infecting the visitor devices with some other piece of malware when downloading stuffs.

There are various ways they can upload their malware to websites, such as disguised plugins, manipulation of source code, malicious redirection, drive-by downloads, phishing, or through backdoors etc.

What Does Website Malware Do?

Website malware can negatively impact the website and its visitors in many ways. That depends on what the hackers intent is. Some of the reasons include monetary gain or just hacktivism for the fun of it. Unlike useful applications designed to benefit website owners, malware is harmful and created to damage or steal information or illegitimately monetize a website’s compromised environment.

One of the many ways malware can work on a website include instant redirect to another website, add pop-up ads that your computer has been infected and you need to consult some “tech support” number to clean up the malware. Maybe you purchase a shoe online, only to find out days later that your credit card and personal information was skimmed by a hacker.

Most of the website malware hackers leave contains features which allow these attackers to evade detection or gain and maintain unauthorized access to a compromised environment. Some of the different types of website malware include credit card hijackers, injected spam content, malicious redirects, or even website defacements.

The ad pop up also know as Malvertising occurs when a website is infected with any malware or suspicious script file which is injected on the domain. And sometimes it occurs when the creative is redirecting to malicious third party landing page URL, which can be triggered when there is a different intermediate redirect from the landing page.

Other Causes of Domain Infections

There are other things that can lead to suspicion for domains.

  • Domain is located on a hosting network with a bad reputation
  • Domain has network connections to bad domains (like nameservers, etc)
  • Domain has network connections to individuals with bad reputations
  • Domain has network connections to sources of bad traffic
  • Domain is sent through a MTA with bad behavior

It’s essential to remove website malware as soon as possible to reduce the risk to customers, protect your website’s reputation, mitigate SEO issues, and avoid security warnings or blocklisting from search engines like Google.

If you have many websites on the same shared or VPS server, it is highly recommended that you scan all of them. Cross-website contamination is one of the leading causes of infection and reinfections. We encourage every website developer to isolate their clients’ hosting and web accounts.
