Stuffing the Spammers!

Sunday, September 16, 2007

I'm really, truly fed up with spam. Every day when the spam arrives and Norton Security moves it into the Norton Anti-spam folder of my Outlook email client, I wonder how anyone can be so incredibly stupid as to waste their time sending me such garbage.

Let's face it; I never read it. I never buy anything from unsolicited sources or do anything as a result of spam. I detest it! And God knows I don't need viagra, however many times it's offered.

What fool would send anyone a message about a mortgage application approval when he has owned his house for years?

What fool would write offering me a peep at her new porn site? I'm not interested in porn ... I prefer the real thing. Offer me something tangible and I may get excited.

I guess you probably feel the same.

Unfortunately, the plague of spam isn't going to fade away any time soon, although authorities (at least in Australia) have started taking legal action and imposing hefty penalties for spamming. Hallelujah!

As a last resort, I decided to make my own small contribution to reducing the spam plague. If each of us does something, the cumulative effect will be damaging to the spammers. Here's what I did. I've collected thousands of email addresses that arrived in spam messages and ended up in my blacklist. I decided I'd give those people using automatic harvesting software an opportunity to suck up all those addresses and reuse them.

I've dedicated quite a few pages on my site that have nothing but the email addresses from the blacklist. That is, the addresses of the spammers, most of which are false and don't lead to anyone ... at least not to anyone who can read (otherwise I'd include an obscene message).

When the spam harvesting software goes through my site, it won't find a single working email address in my site proper, but it will stumble on a goldmine of addresses and load them into it's database. It will be stuffed full of email addresses, none of which work. The spammers will pay to send them out and they'll bounce somewhere, hopefully right back to them.

Imagine what would happen if we all did that? There would be so many dud addresses floating around that harvesting would be a waste of time. the spammers would all go away and do something legitimate ... perhaps.

You and I would get some relief from these annoying intruders in our email inboxes.

If you are in a position to load your site with a few thousand dud email addressesArticle Search, why not give it a go and Stuff the Spammers?

The Anti Spam Challenge – Minimizing False Positives



Email is the quintessential business communication tool, so when it doesn’t work like it’s supposed to, business suffers. Anti spam software is designed to protect your inbox from unwanted messages, but unless your system is properly trained even the best software misses the mark and flags legitimate messages as spam. These messages are referred to as “false positives.”

While consumer and ISP anti spam products focus on blocking messages and even consider some false positives acceptable, businesses require anti spam solutions that treat their messages as very valuable. Failing to receive critical messages in a timely fashion can do irreparable damage to customer and partner relationships and cause important orders to be missed, so eliminating false positives while maintaining high anti spam accuracy is paramount to any enterprise anti spam solution.

What causes false positives?
Different anti spam solutions utilize different methods of detecting and blocking spam. Anti spam software typically uses content filtering or Bayesian Logic, an advanced content filtering method, to score each email, looking for certain tell-tale signs of spammer habits such as frequently used terms like “Viagra” or “click here.” Other anti spam solutions reference blacklists and whitelists to determine whether the sender has shown spammer tendencies in the past. A false positive can occur when a legitimate sender raises enough red flags, either by using too many “spam terms” or sending from an IP address that has been used by spammers in the past.

Minimizing False Positives
Although it takes a person only a moment to process a message and identify it as spam, it is difficult to automate that human process because no single message characteristic consistently identifies spam. In fact, there are hundreds of different message characteristics that may indicate an email is spam, and an effective anti spam solution must be capable of employing multiple spam detection techniques to effectively cover all bases.

A comprehensive anti spam approach involves examining both message content and sender history in tandem. By using a reputation system to evaluate senders based on their past behavior, a more accurate picture of their intentions and legitimacy can be discerned, and a solution’s false positive rate can be further lowered. Has the sender engaged in spamming, virus distribution or phishing attacks in the past? If not, the likelihood of their message getting past the email gateway just went up, and the chances of a false positive declined accordingly. If they have, an effective reputation system knows and flags the message.

Self-Optimization
In order to be most effective, anti spam solutions must learn based on a recipient’s preferences. While most of us prefer not to receive emails containing the term Viagra, some medical organizations might need to receive these emails in order to process patient data. In order to best learn your organizational preferences, anti spam solutions should put filtered emails into a quarantine that allows users to review and make decisions as to whether a particular message is spam. Making this quarantine available to the end-user lowers the administration costs and increases the accuracy of the anti spam system.

Each time a user makes a decision about whether a particular email is or is not spam, the system becomes more personalized and intelligent about filtering email for that individual in the future. Over time, users find that they rarely need to review their quarantines anymore because the system has learned how to identify messages that are important to that user.

Don’t throw the baby out with the bathwater
An effective, accurate anti spam solution aggregates multiple spam detection technologies, combining the benefits of each individual technique to stop spam while minimizing false positives. It also puts suspected spam into a quarantine that is available to end-users, and learns how to better identify spam in the future.

BUSTED: Anti Spam Forces Bankrupt Super-Spammer Scott Richter



Scott Richter, the self-proclaimed "Spam King," admittedly responsible for sending literally billions of Unsolicited Commercial Email messages (UCE), made headlines again when his spam-fed cash cow, OptInRealBig.com, filed for bankruptcy protection.



Microsoft scores one for the good guys
Scott Richter, the self-proclaimed “Spam King,” just can’t seem to get enough attention. Admittedly responsible for sending literally billions of Unsolicited Commercial Email messages (UCE), Richter made headlines again recently when his spam-fed cash cow, OptInRealBig.com, filed for bankruptcy protection in U.S. federal court in his home state of Colorado. According to Richter’s father (who is also his attorney), “It’s the legal fees that are battering the company. OptIn is profitable but for these lawsuits.”

At the time of its bankruptcy filing, OptInRealBig.com claimed assets of less than $10 million and liabilities of over $50 million. Richter claimed his company made $15 million a year sending more than 15 million email messages per day. However, in 2003, OptInRealBig was dealt a powerful 1-2 punch from Microsoft and Eliot Spitzer, the Attorney General of New York; both sued Richter under local state anti spam laws. Although the New York case was settled out of court last year, Richter has had no such luck dealing with Microsoft, whose claims top $19 million.

A Case of Global Amnesia?
Richter's company and others like it market products ranging from diet pills to pornography. He’s also been accused of using spam to extract personal information from unsuspecting recipients. For instance, one alleged scheme hatched by Richter and his associates promised recipients a copy of a "Girls Gone Wild" DVD if the recipient registered on a website. The registration information was then used to bombard the recipient with more and more spam.

Richter contends that his methods are all legal, and that he’s just a regular guy trying to do right by the world; he’s even gone so far as to claim that he’s a “victim” of overzealous anti spam companies and prosecutors. “We don't spam,” explained Richter in an August 2004 PC World interview. “The biggest problem is when people get an email that they think they didn't sign up for or don't remember signing up for, and they call it spam.”

To hear Richter tell it, tens of millions of people simply forgot that they had previously asked to receive his messages. According to the state of New York, however, he falsified header information and used deceptive routing and domain purchase practices in order to get his messages through. The lawsuit also accused Richter of using a network of approximately 500 “zombie” computers to send his messages. When asked how so many users could have subscribed and not remember doing so, Richter claimed the signups must have been via anonymous "partners of our partners" web sites, the names of which slipped his mind.

Not Just an Online Threat
Evidently not satisfied with stealing bandwidth, Richter also shows a penchant for heavy equipment. In an unrelated 2003 case, he was put on probation after pleading guilty to a felony charge of receiving stolen items worth more than $10,000. According to court records, an informant's tip regarding a stolen Bobcat loader led undercover officers to Richter. Over the course of 13 months, the officers proceeded to strike deals with him for a Honda generator, hundreds of cases of cigarettes, three laptop computers and other items, all offered at suspiciously low prices and purchased in some of Denver’s seediest neighborhoods. In addition to probation, Richter was also ordered to pay $38,000 in restitution for the stolen goods.

Despite his guilty plea, Richter maintains his innocence, saying he pleaded guilty to the felony charges because it was "easier to be done with it," and he had "too much stuff going on in my life."

What’s Next for Scott Richter?
The 5-year-old OptInRealBig.com, which employed 25 people last year and had 350 clients, will continue to operate under Chapter 11 bankruptcy protection. While the bankruptcy filing shows the power of legislation and legal action from parties with a vested interest in stopping spam, Richter is not likely to fade quietly into the sunset. Under Chapter 11 bankruptcy laws, the company must follow a court-supervised “debt rehabilitation” plan to pay off creditors, but is not required to modify its business practices. None of OptInRealBig’s assets will be liquidated, meaning the company’s stable of spam cannons will remain active. The bottom line: Scott Richter will not be required to stop sending UCE in the immediate future, pending ongoing litigation intended to determine exactly what spam is in legal terms. In the meantime, the best defense against spam is a comprehensive gateway solution that will guard against all manner of email threatsFree Reprint Articles, especially spammers like Scott Richter.
