With PDF type of spam, a junk email is sent out with a PDF file attachment, which most anti-spam filters cannot or do not read. These attachments range from rudimentary to professional-looking documents. The text in the body of the email is usually nonsensical gobbledygook that the spam-filter does not recognize as junk mail.

The upside to the use of image and PDF spam is that so far, there is no hard evidence that either one can be used to embed malicious software on the recipient’s computer. The only harm is done to those who do what the message says. Spammers have also begun to experiment with attachments in different file types such as excel and zip files.

Protecting Your Children

Like all other Internet users, children are just as susceptible to receiving spam as are adults. And because spam is an equal opportunity menace, kids are just as likely to receive spam that contains adult and pornographic material. While there is really no way to totally eliminate the possibility of your kids receiving spam, there are steps you can take to minimize it.

Whitelists - Set up an email account for your child that “whitelists” only specific email addresses. A whitelist is just a list of trusted and approved email addresses. For example, you can have the addresses of your child’s grandparents, aunts and uncles whitelisted. Whenever email is received from any of the whitelisted addresses, it goes directly to your child’s inbox. All other email addresses are blocked.

Spammers tend to direct the dictionary attacks at the large email companies, which have a large number of customers, which can be your kid.

Be sure to log into your child’s email account on a regular basis to monitor the incoming and outgoing messages, and to ensure that the spam filter and spam block are working appropriately.

Just about anyone who accesses the Internet will know what spam is. Spam is the biggest problem of Internet email just as for the Postal Service the problem is junk mail.

Spam can be considered to be email that is unsolicited. Many times the intent is commercial but most times it is unwelcome. Spam is sent out in bulk by programs that are automated. This spam reaches millions of users of email, many times offering services and products that include pornography, get rich plans, and prescription medication.

Even though the content of spam can be objectionable it’s the method of delivery that most people get upset about. Junk mail is delivered by the Postal Service and the sender pays the cost. Spam costs usually hit the receiver and the ones who transmit it. The sender of spam will incur some cost for using paid services to send the email but the cost is usually small.

So just why does everyone hate spam? You have the option of getting rid of it by simply deleting it. When you get one or two spam emails in one day you’ll only be annoyed. But when you get 20 or one hundred spam email every day it can get to be a problem.

Spam was mostly seen on USENET (newsgroups that are created to talk about certain topics) before email became a main source of communication. As email became more advanced the advantage of sending email in bunches started to become more popular. This is called cross posting.

Cross posting was very quickly picked up by spammers. They could send the same message to thousands of people in the newsgroup without having to pay attention to what their individual interests were.

As email became more popular spammers found a whole new way to generate harm. They could use spambots (software) to harvest email addresses that had been posted on newsgroups or websites. Once they had all these addresses they could send out their messages to thousands of receivers at one time.

A spambot is a program that is used to collect email for address lists so that spammers can target many people at one time.

Spam is profitable just because of the huge number of messages that are sent out. This is called “shotgun” advertising and considered to be legitimate advertising. Many legit advertisers will use something known as “targeted” marketing where people voluntarily give their email addresses to the vendor. This way only welcomed messages are sent out.

The majority of people don’t fall for schemes to get rich or are interested in randomly buying products. However, just one recipient out of thousands will give out their credit card number. This alone will repay the spammer with rewards.

There is no need to despair since spam is being battled on more that one front. There are trade groups and companies, technology, and legislation that are joining forces to put spam into the past.

This effort may not be effective 100% simply because what one person considers to be spam another will think of as the latest product they want to buy. At least progress is being made.

Until then you don’t need to stand by waiting for a solution to spam. Other tips for battling spam will be discussed in later articles.
