How do cybercriminals use JavaScript maliciously?

Explanation:

Formjacking has evolved and become stealthier in the last couple of months, where attackers are now injecting malicious codes into websites to steal more than just credit card information. As a continuation from Symantec’s ISTR 24 report, Symantec has launched an in-depth analysis on formjacking attacks that are frequently in the news highlighting how websites and consumers have been affected in the last one year.

“Each month we discover thousands of formjacking infected websites, which generate millions of dollars for the cyber criminals” warned Candid Wueest, Principal Threat Researcher at cyber security company Symantec.

Before formjacking became popular, cyber criminals were already targeting e-commerce platforms. However, they were mainly attacking the e-commerce or payment systems directly to steal stored transactions, or they used phishing attacks to redirect customers to fake websites. Formjacking is not just about payment card data but it also is used to steal passwords and other personal data from websites.
