Which of the following describes e-fraud?

E-fraud specifically refers to fraudulent activities that are carried out using the Internet. This includes a wide range of deceptive practices such as phishing schemes, online scams, and fraudulent e-commerce transactions. The defining characteristic of e-fraud is its reliance on digital platforms to execute illegal activities, which distinguishes it from other forms of fraud that may not utilize the Internet as a medium.

The other options focus on different forms of fraudulent activity that do not encapsulate the essence of e-fraud. Traditional methods of fraud refer to non-digital practices, while fraudulent activities via phone calls are typically categorized as telemarketing fraud. Furthermore, limiting fraudulent activities solely related to bank transactions does not encompass the broad spectrum of online fraud that can occur across various platforms. Thus, the correct answer accurately reflects the nature of e-fraud as it relates to its execution via online means.
