The term “formjacking” describes the fraudulent use of a company’s existing online forms to gain access to personal information, credit card numbers or even hacking a website. Hackers gain access by changing the HTML form action or form fields. They do this by intercepting the traffic between your web browser and the server that is hosting your online shopping site.
How does formjacking work?
Hackers change the homepage with a fake checkout page in order to trick users into divulging private information such as credit card numbers. This process bypasses the security measures that are already in place for your online shopping site. In addition, well-known systems can be hacked using formjacking to increase the fraudulent activity of cybercriminals.
Why are hackers targeting forms?
The most common ways that a hacker may obtain your private information is by using key loggers or spoofing websites and email accounts. However, another popular way for hackers to steal an individual’s personal data is through the user’s web browser while they’re entering sensitive information on existing company forms. These existing company forms include but are not limited to:
- Order forms
- Login pages
- Registration pages
Prevention tips for formjacking attacks
- Make sure your web browser is up-to-date with all the latest security patches and updates
- Only fill out online forms once you have made sure that there is a secure connection between your computer and company’s server which uses HTTPS encryption
- Always look for “https” in the web address bar of the browser before entering any personal information
- Refrain from clicking on links that appear suspicious
- Always pay attention to the URL, if it is not a website that you are familiar with then don’t enter any of your personal information
- Protect your Wi-Fi connected device by setting up a password for it or using WPA2 encryption
How to protect your customers from formjacking when you’re a website owner
- The first step is to make sure your site uses HTTPS encryption. The “S” at the end of https stands for “secure”.
- Every single one of your forms should be secure as well, which means that all form action and form fields should be using SSL encryption. Hackers can use an unsecured form to steal data from your customers if they are not careful when entering their information.
- Make sure your contact forms and other similar types of online forms do not ask for sensitive data that is unnecessary in order to complete a transaction or request
- Use CAPTCHA on registration, login and checkout pages to protect against automated spam submissions.
- Have a company policy manual which states what actions should be taken whenever customers report phishing emails or if their accounts have been hacked. Make sure employees understand their role in protecting your customers from fraud
- Inform customers about upcoming changes to your online forms which may affect the information they submit after an update.
Each website should provide their customers with a secure and positive customer service experience at all times. Never leave your site’s security up to chance, implement these tips into your site’s daily operations in order to protect both you and your customer.
The most common forms that are hacked by hackers
- Login pages
- Password reset form
- Registration page
- Order forms
- Online payment systems (e.g. Paypal)
Examples of formjacking attacks
The most common example of formjacking is when a hacker accesses your personal social media account without permission. The hacker then changes the password to lock out the original owner while they wait for an unsuspecting user to share their login information on a fake version of the site.
Another example would be hackers spoofing websites in order to hijack users’ login credentials or steal credit card details. This type of attack often occurs after scammers send phishing emails which appear to be from companies that are well-known and widely trusted.
