How does Formjacking work?

Formjacking attack takes place by inserting malicious code into an e-commerce or banking website. The code is then responsible for stealing or capturing payment information such as card details, names, and other personal information. Sometimes the information is obtained by the hackers as soon as you enter it in the fields of the web page instead of capturing it at the time of sending it for further processing.Hacking Android: How your phone can be compromised by a rogue app The stolen data is sent to servers from where it stored, which is further reused or sold to someone. They then sell the sensitive information gathered online mostly on the dark web. There are plenty of international and Russian websites where you can find the stolen bank credentials with some of them showing themselves as a professional website. This complete process goes unnoticed, and the affected user remains unaware until the fraud happens.

  • Check your credit card bill monthly to verify that there is no bogus transaction and if there is any inform your creditor as soon as possible.
  • Keep an eye on your credit score. An unexpected drop in your score shows a formjacking attack.
