Everything you need to know about formjacking
Cybercriminals are coming up with ever smarter ways to attack businesses and consumers. One relatively new method that is appearing with increasing frequency is formjacking. But what exactly is it, and how can you protect yourself and your organization from it? In this blog, we explain it to you! 🚀
What is formjacking? 🤔
Formjacking is a form of cybercrime in which hackers inject malicious code into online forms, for example on Web shops. The goal? To intercept sensitive information, such as:
- 💳 Credit card information
- 🔑 Passwords
- 📧 Personal information such as names and addresses
The data collected is often resold or used for fraud. Many websites process login information, personal data or payment information through these fields.
How does formjacking work? 🛠️
Formjacking follows a simple but effective process:
- Hackers inject a piece of malicious JavaScript code into the website.
- When a customer enters their information into the form (such as a payment page), the information is sent directly to the hackers.
- The user does not notice anything, as the website and payment process appear to function normally. 😟
Why is formjacking dangerous? 🚨
- Invisibility: Users and even Web site administrators often do not notice they have been hacked.
- Impact on trust: If customers discover that your website is insecure, it damages your company’s reputation.
- High costs: The financial damage from fraud can be significant, both for customers and businesses.

Fortunately, there are steps you can take to minimize the risks. Here are some tips:
- Ensure regular updates 🔄
