spam definition

Email is a universal service for billions of people worldwide. It is one of the most popular services worldwide, but it has the highest vulnerability to Internet users.  These e-mails are also known as “junk mail”, an unwanted email,  the majority of an advertiser using these junk emails. However, criminals send harmful links, malware, or deceptive content through spam.

It aims to get sensitive information such as a social security number or bank account information. Most of the spam comes from different computers on networks infected by a virus or worm. These infected computers send out bulk emails as much as possible. Some of the common indicators of spamming are the following:

• An email has no subject line.
• An email is requesting an update to an account.
• The email text has misspelled words or strange punctuation.
• Links within the email are long and cryptic.
• An email looks like correspondence from a legitimate business.
• The email requests that the user open an attachment.
• Repeating special chars in the mail Like!!!! Or $$$
• Colors: There are many different colors in tags.
• Repeated word keywords.
• The E-mail recipient’s email address is missing.
• Capital letters to all letters, especially in the subject line
• Significant emails that contain lots of images or binaries
• Huge images, about the size of 1600+ bytes of words
• The high amount of blank lines in the message body
• The date is a few hours before or after receiving or missing
• Text and background color are the same or similar.

If someone receives an email containing one or more of these indicators, the receiver should not open the mail or any attachments in this mail. Nearly all email service providers filter spam, but sadly, it still consumes bandwidth, and the recipient’s server still has to process the message.

Why Spam is a Problem

It wastes people’s time and consumes more network bandwidth. Many organizations and individuals are fighting against spammers. But it is still impossible to prevent these junk emails. However, some online services have policies to stop spammers from spamming their subscribers.
