How To Identify Spam

Most of us have opened our email program and found, alongside correspondence from people that we know, offers for products from commercial web sites. Some of these emails we expect. We have asked to be notified of sales and other opportunities or joined a mailing list offered by the company.

Many times, however, the offers are from companies that we have never done business with and may have never even heard of. This is Spam, unsolicited bulk email, and can quickly lead to a massive overload of your inbox.

Identifying Spam as soon as it occurs is the first step to preventing it from happening again. Once your email address is in circulation with these companies, you are well on your way to a very nasty problem. Advertising from legitimate companies is one form. The rest are for illegal services, pornographic material, questionable products, and fraudulent schemes. It is invasive and many times illegal. Spam is the worst form of junk mail and a typical reason why many people have to change their email addresses.

In best cases, the clue can be found in the subject line. If you are offered quick money or a chance to find your long lost high school classmate, you can probably guess that it is Spam.

You may be amazed that, as you read your email, that these companies claim a right to send you this email because you have a relationship with one of their partners or affiliates. All that this may mean is that they bought your email address from another company with dubious privacy policies. It is still Spam.

Spammers will try to trick you. Unfortunately for us, Spammers only need a response rate, by some estimates, of 0.0001% in order to be profitable. This means that they will use practically any measure to get you to open it before hitting the delete button. You may receive an email from Grandma or one asking for help in the subject line. Before you know it, you are reading their advertisement, if only out of curiosity.

Check the dates and times on any email that you are unsure of. These companies know that many email programs will sort the inbox by the earliest mail sent. As a result, they place false send dates and times on their Spam hoping that you will open them first.

The worst has to be the ones that seem to come from companies that you know and trust. They may claim to be from your internet service provider in the subject line or have a similar address to that companys name. It may look like it is from the accounts payable department of a major law firm.

Spammers count on your curiosity and hope that you will respond. Even if you dont buy anything, they now know that your email address is connected to a live person and, if nothing else, can sell that address to someone else.

Read the To and From fields in any questionable email that you receive. If the To field is empty or filled with an anonymous address, then you have Spam. An anonymous address is typically something like freeoffer@happydays.com.

An address from someone that you do not know through an account at hotmail, yahoo, or msn is probably Spam. These are anonymous, easy to get accounts that spammers use and then discard when they are done. By the time the Service Provider has been made aware that spam is originating from these accounts, the spammer is gone.

Scrambled, random addresses (X12YT853@yahoo.com) from accounts like these are definitely not to be trusted regardless of the content.

Finally, if the email contains a story in which you are asked to do anything to help anyone, check the story out online. There are several great websites like truthorfiction.com that will help you sort through any potential scams or hoaxes perpetuated through email.

These stories can range from silly pranks to dangerous fraud schemes and may need to be reported to the proper authorities before someone, like you, finds their bank account drained.

What To Do When You Get Spam

When you go to your mailbox and find pieces of junk mail mixed in with important correspondence, you throw it out. It is a mild nuisance and you probably dont even give it a second thought. Unfortunately, most people do the same when spam arrives in their inbox. They just delete it.

While that does get rid of an individual email, more needs to be done to control what can become an overwhelming problem. Liken spam to cockroaches; see one in your cabinet and you know that you likely have an infestation that needs to be dealt with swiftly.

To begin with, do not respond to the spam ever. There are usually two ways that spam recipients make this mistake. First is the opt-out clause that appears at the bottom of the email. It appears to be a legal statement giving you the right to remove yourself from this mailing list. Unless you legitimately authorized the company to send you mail, in which case this is not spam, do not follow this link. Most often this link is simply a way for the spammers to identify your email address as valid. Now they can sell your address to other spammers and thank you for making their work easier by continuing to send you the spam you didnt want in the first place.

The second manner in which this error occurs is when, out of total frustration, you reply to the sender with a firm statement of your disgust. This usually happens when the spam is pornographic material and despite your best efforts, keeps appearing in your inbox. Sometimes the reply will not work because the senders email address is a fake one and it will just bounce back to you as undeliverable. Count yourself lucky because the alternative means that they now have a confirmation of your address.

Next, read the email header. The header contains the full path of computers through which the email passed to get to you. Most pieces of email pass through at least four computers the spammers, their ISP, your ISP, and finally yours. Since the stated from address is usually a fake one, this is the most reliable way to track down the spammers ISP, at the very least.

Each computer that the spam travels through will add lines to the header stating who they are, who the mail came from, and where they are sending it. Headers can seem complicated, but in most cases you will be able to at least recognize other ISPs. If your mail is through Yahoo and you see juno.com in the mix, then you know that you can report the spam to Juno.

When reporting spam, you will need to cut and paste the full header path into the email to give the experts the opportunity to track down the offender. To read an email header, you typically just right click on the email and then choose properties, options, or header depending on which email program you are using.

Finally, forward the spam to a number of authorities. The first would be the spammers ISP. If you cannot tell who that may be, send the spam to your ISP. Additionally, several websites are available to help you report spam, like spamcop.net.

Second, forward the spam to the Federal Trade Commission at uce@ftc.gov. While they will not take action on your behalf, they will add the spam to a database compiled on known UCE (unsolicited commercial email).

If the spam is a 419 Scam, or Nigerian Advance Fee Fraud, fax a copy of the email and its headers to the United States Secret Service. You will know this spam when you read it an exiled African leader of some sort needs your help and bank account information. These scams have defrauded many and need to be taken seriously.

Now you may delete the spam.

Is Your Computer A Spam Zombie?

Do you know your computer could be responsbile for sending spam without you even knowing about it?

Over the past few years you've all become familiar with the terms spam, spam filter, whitelists, blacklists and a whole myriad of other terminology associated with the problem of spam. You now have to add a new and extremely worrying phrase to that list - spam zombie.

With the net closing in around them spammers are looking for new and more inventive ways to send out their junk email. Spam filters and challenge response systems are becoming progressively more intelligent and blocking more spam each day. What was a spammer to do? The spammers took the next step - infiltrating your PC and using it as a spamming tool.

When most of you think of the word zombie you're reminded of old B movies with groaning zombies chasing the terrified actress through a castle, swamp or whatever low cost setting the movie revolved around. Spam zombies are, however, far more real and far more dangerous.

A spam zombie is when your computer is taken over by a type of virus called a Trojan. Once this Trojan virus is on your computer it sets up an SMTP (Simple Mail Transfer Protocol) application which allows it to begin sending email directly from your PC to tens of thousands of victims. This all happens invisibly in the background and can be difficult to detect for even the experienced computer user.

How do these Trojans get onto your computer? As in most cases they come from porn, warez or similar sites. One of the first spam zombie trojans to appear became available via a link on sites promising viewers free access to a porno webcam. One click later and the Trojan is installed on your computer ready to send out spam. Phatbot and Proxy-Guzu are two of the more common Trojans used for the purpose of turning your computer into a spam zombie.

How can you check if your computer has become a spam zombie? Make absolutely certain that both your anti-virus and firewall software have current detection signatures and have been completely patched and updated. Working online without taking these necessary security precautions is simply asking for trouble.

Internet Service Providers are under huge pressure to quarantine the IP address of any computer which has been turned into a spam zombie. This is done on the basis that the ISP risks their entire IP range being blacklisted or banned by some spam filtering services or companies.

The very least you owe yourself is to run a full virus and spyware scan on your computer today. You might be unpleasantly surprised at what you'll find lurking there.

The Trouble With Spam Is....

Reacting to spam won't solve it. Taking a pro-active approach is sometimes all that's needed.

Each day we all face the same challenge. Spam. It doesn't matter if you're a home computer user or the head of IT for a multinational limiting or totally preventing the distribution of junk email to your computer(s) is now a daily chore.

The sheer frustration that spam causes combined with the number of lost man hours adds up to junk email being a very real problem for all involved. You have to filter through all the junk to find your own personal or work email. This on its own is annoying enough. When you consider the security risks from spyware, trojans, diallers and attempted identity theft spam becomes much more than just an annoyance - it becomes a minefield for any computer user.

So what can you do to block spam? The first step each user should take is to simply limit the number of people who know your personal email address. If you have a work email address then just use it for work. For home users only distribute your email address to people you know and trust. This simple move can cut your spam problems by 50%.

But what about all those online forms I need to fill in? No problem. Use a free email service like Hotmail or Gmail for this purpose. Treat it as a throwaway account that you can use as a buffer between your true personal email address and the rest of the world. Let it fill up with junk email and then just login once a week and delete everything you see.

Your password. It's amazing how many people set the password for their email account to abc123 or something similar. These passwords are incredibly easy for spammers to guess and would give them easy access to your mail account. The password for your email account should follow corporate standards of being 6 - 8 characters long and be alphanumeric (a mixture of numbers and letters). Make it longer if you can. Using a weak password is just asking for trouble.

If you're already receiving a ton of spam then you'll need to invest in a spam blocker. There are free spam blockers you can download and also also their paid equivalents. A great spam blocker can cost you as little as $30 and you'll see an immediate reduction in the amount of spam you're receiving.

Over and above installing software on your computer (especially for Mac users as your choices are limited) you could sign up for one of the web based challenge response spam blockers like Mailblocks or SpamArrest. Both of these services are ideal for somebody who's on the move a lot. Also because they're web based there's no software to install so they're perfect for Mac or PocketPC/Palm users.

Taking a pro-active anti spam stance is the next step. If you get junk email from people then check the mail headers and report any offensive email to the hosting company or ISP involved. Never, ever reply to spam directly. This simply confirms to the spammer that your email address is active. Also never click on any hyperlinks in any junk email - this again confirms your existence and can lead to a virus being downloaded directly onto your PC. Filter the spam, report the abusers, delete the remaining junk email.

Spam can be stopped. Not by some corporate giant or genius programmer. It can be stopped by each of you individually. Spammers rely on the widespread availability of email addresses and for people to reply to these emails or click on the links within the emails. The sooner people stop reacting emotionally to spam and simply filter, report and delete the offensive mail itself the sooner the lucrative market of bulk email will dry up for the spammers.
