For a spammer, the use of PDF files is advantageous because PDF files are so commonly used in the business world. In fact, several companies allow or even require their business email systems to deliver these documents to the recipient. This makes it very likely that this PDF spam will reach the user's inbox.
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 Kids
Today, many children have an email address that they use to email their friends, submit homework, etc. It is a fun, inexpensive and instant way to keep in touch. However, as the volume of spam keeps rising, the need to protect children from the dangers of spam is a growing concern.
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.
