Let’s look at ways Cyber Criminals Use Email to Commit Fraud.
- Spamming: Unwanted, bulk emails sent to recipients for some motive such as advertising, stealing personal information, installation of malware, or selling illegal/prohibited items. Often it is called the negative side of email marketing.
- Phishing: Cyber criminals impersonate individuals, organizations, and so on via emails. These fraudulent emails may appear from various government organizations such as the income tax department stating that you have not filed the income tax return on time, so you have to pay the penalty; it may pretend to be from a bank asking to update your KYC details; they send an exciting sale to offer free shopping voucher or cash back offer, or they may send threatening email stating that your email account will be closed if you don't respond to this email. As you click on the mentioned link in the email, it directs you to a fake website which is a look-alike of a legitimate website. An email related to corona update is a new phishing trend.
- Email bombing: Cyber criminals send a large number of emails in a very short span of time to flood your inbox using automated programs. It results in bouncing of emails as the email quota exceeds. Due to this, you may miss important communication, which may further result in the hanging of the webserver. Normally, official emails are the target as cyber criminals may have various intentions, such as taking control of your email id and harming the mail server by performing a denial of service (DoS) attack.
- Spoofing: Emails are created with a forged sender address; often, the sender pretends to be someone known to the recipient. In spoofed emails, the sender's real identity is hidden, and he intends to get the recipient's financial details either by luring the recipient or by installing malware.
