How Spammers Work

 

Spammers are becoming increasingly sophisticated and aggressive in their tactics and techniques. There are many tricks that spammers use to gain access to your Inbox. One recent technique is quite ingenuous and is fooling most anti-spam products – but not Spamjadoo. The revolutionary ESP (Eliminate Spam at Protocol level) technology is based on the privacy paradigm enforced at the protocol level. It does not depend on content, and is therefore fool-proof and unbreakable.

 

Underlying principles

Spamming is based primarily on two facts : sending emails is practically free, and, email protocols are based on trust and honor. These are used to abuse your privacy – and thanks to cheap internet bandwidth, the operating costs for spammers are almost zero. Add a commercial value (spamming is usually done as a business), and it’s not hard to see why spam exists and why it is getting worse all the time.

There’s a bond that joins hackers, spammers and virus writers. Many virus’s are aimed at acquiring your contact book, taking over your email account and compromising network security. The most popular method to send virus’s is via spam. If you block spam successfully, you also get a raised security level from virus’s and hackers.

 

Dictionary attacks

The spammer takes a "dictionary" of common words and names, combines them, and sends email addressed to all different variations such as johndoe1@example.com, johndoe2@example.com, johndoe3@example.com. This attack is typically directed at email providers that have a large base of users.

 

Email spoofing

 

The spammer favored trick currently, it fakes the email header to make the email look like it came from someone else. Spammers use spoofing to get you to open and respond to their mail. The senders’ address may be someone you know, or a bank, ISP or

some other institution or service provider. Sometimes, the spam may ask you to send your personal, credit card or bank account information.
 
 

Social engineering

This ploy tricks users into opening the spam by pretending to know the person or trying to lure the person with a "personal" subject line. Typical subject lines include "The doc you wanted" "Urgent and Confidential," "We need to meet," "I have money for you," or "It snowed again."

 

Unsubscribe links
 

Sometimes the spam mail offers you a link that promises to unsubscribe you from their mailing list. The offer is often just a hoax, intended to confirm to the spammer that you exist, and that your email account is correct and live.

 

Mining message boards and chat rooms
 

Spammers use automated robots, or "bots," to search the Internet and grab your email address from public places, such as chat rooms and message boards. Even publishing your email address on your website is an invitation to spam.

 

Open proxy, third-party servers
 

Open proxies help spammers maintain anonymity. Spammers can send mail using such servers while hiding their true identities and Internet locations (IP addresses).

 

Web beacons
 

An email may contain an image that is invisible to the recipient - this is sometimes called an "invisible GIF" or "web beacon." Once the email is opened, the spammer is alerted that your address is accurate.

 

Inserting random strings of text and characters
 

Since the common spam defense is based on text string filtering, spammers insert text to fool the filters but still leave the mail readable. So, the subject line may include V_I_A_G_R_A.

 

Chain Letters
 

Almost all of us get chain letters that invite us to forward the message on to our friends. The chain letter may offer a few cents for every forward, or warn of bad luck if you send to less than five people. These are hoaxes created to promote spam – spammers recover huge number of valid email addresses to target later with spam mails.

 

Hacks, spyware, malware
 

The purpose of many virus’s and other malware is to collect your address book data. This data is passed on to spam engines. Sometimes, your PC is made into a spam engine spewing out spam – without your being aware of it.

It's easy to see why no simple solution is possible, why no single technique, whether content-filtering, or disposable mailboxes, or challenge/response, provide a comprehensive and convenient answer. This is why you need the sophisticated privacy based protection that the unique
ESP technology enables with Spamjadoo.
