Malware attacks inject code with malicious logic meant to hurt your site's performance in one way or another. The injection corrupts your site's generated HTML, appending malicious DOM components that can alter how your site works in many ways.
Some common buggy malware infection effects include:
- It may perform unconditional redirection. This is where visitors to your site who intend to spend time there are automatically redirected to another site they don't want or intend to visit.
- A malware attack may inject SPAM into the body of your website's HTML code.
- It can steal user credentials or payment information.
Each of these effects are different in how it could harm your site, but they are no less dangerous. The redirection will frustrate your users, keeping them from accessing your site. It could cause them to give up and go to your competitors' page instead. SPAM woven into your site's HTML can leave your visitors receiving unwanted messages or offers that only serve to annoy them.
Stealing user credentials or payment information may be the worst sin malware commits; it leads to your visitors being defrauded. It can also lead to a loss of trust in your site and overall brand. Simply put, you don't want to be the website that, after being compromised, gives out your audience's valuable financial information.
There are seemingly endless ways for malware to ruin your site. But there's one other potential impact on your site's health that can also lead to a loss of customers or visitors.
