Mechanism of Formjacking
When a buyer on shopping website fills the personal details on the payment form and clicks the “submit” button, the malicious JScript code collects all the details and passes it on to the hacker’s computer. The payment from usually comprises of details such as debit card number, cvv, your card’s PIN, and that is enough for a hacker to misuse it and committing debit/credit card fraud.
Many surveys show that any company, anywhere in the world, which processes online payments, is also a potential victim of this fraud.
How are websites being compromised because of formjacking?
There are many ways attackers can attempt to compromise websites. The attackers use a supply chain attack to gain access to the website and modify the code on its payment page. This chain allows attackers to gain access to websites of large companies. These attacks are particularly challenging because it breaks the hardest walls of your cybersecurity system.
The hackers widely targeted third-party companies that are used on e-commerce sites to manage analytics, websites support, and more. Researchers say that the attackers could potentially infect thousands of websites in one go.
