Classic Spam: Pump and dump

The bottom line: Stock touts are now one of the biggest single categories of spam mail. They are frequently misunderstood by the public, as I describe below. They are nothing more than attempts to profit from the actions of foolish investors. In most cases, they are perpetrated by individual crooks, and not by the companies whose shares are promoted. You should be extremely skeptical of investment information delivered via unsolicited, anonymous e-mail messages.

Illustration from recent stock spam

Update, 15 June 2006: Sic transit gloria mundi. When I prepared this page, we were in the middle of a very heavy wave of stock-spam spewage. In the years since, this stuff has dwindled to nearly zero (in my own inboxes at any rate). Apparently, stock spam is also far less frequently on the minds of visitors to this site, since it has slipped out of the top-five most popular pages of this site (replaced by my page on drug spam). Credit for these developments might well be attributed to a couple of high-profile prosecutions, perhaps also to some policing and public-information efforts by the OTC stock trading industry. I don’t expect a good scam to stay down for long, however, so I will keep this page largely as is for now.

Disclaimers (14 September 2006): Yes, there’s one in every crowd. I recently received a message apparently from an upset investor insinuating that, by posting spams identifying a particular spammed stock, I was actually trying to spread bad publicity and thereby “short” the stock for my own gain. So, this means that the rest of you will henceforth have to sit through the following disclaimers:

  1. I do not trade stocks nor do I have any other interest in the companies named on this page as having had their shares promoted via spam.
  2. I have no knowledge that the companies named on this page are colluding with spammers, in fact, in the absence of any information to the contrary, I assume that they are not.
  3. This website is not to be considered a source of investment advice or information on particular stocks. You are directed to my limited warranty for this site for further information.

So there; now that you are properly briefed, we can get on with the show.

In former years, stock “tips” were one of the biggest constituents of the world’s spam load. I’d guess that these appeals used make up at least one-third of the spam I get in the office, but it has since dwindled quite a bit.

If you get these, you may wonder what they’re about. It isn’t unusual, of course, to get investment tips from your family, friends, or colleagues (or from your stockbroker, for that matter) — but why on earth would someone send out hot stock info to millions of strangers via bulk e-mail? I’m afraid that the answer is not that he wants to make us all rich; in fact, he’s rather hoping for the opposite.

The stock-tip e-mail, like chain letters and pyramid schemes, is yet another example of an old confidence game that has found a new home on the internet: the so-called pump and dump racket. It boils down to simple fraud: the transfer of money from the pockets of the victims to those of the perpetrators, conducted under the pretense of stock trading.

Pump and dump: how it works

The pump-and-dump racket usually starts with a company (a so-called “microcap”) that has very little in the way of capital assets, and whose stock is very infrequently traded. Such a target company will tend to have a very small (sub-dollar or even sub-cent) share price, and these shares are probably “pink-sheet” stocks that do not meet the minimum requirements for trading in the major exchanges (NYSE, NASDAQ, etc.) and even on the over-the-counter bulletin board.

After buying some cheap shares in the stock, the perp sends out bulk e-mails lavishly promoting the chosen stock, with phrases like “strong play,” “watch this one take off” etc. The messages will describe forthcoming business deals and will cite company press releases, along with information from (largely unknown) analysts. The messages urge you to get on the bandwagon now in order to realize the spectacular gains that are about to happen. This stirring-up of interest in the stock is the “pump” part of the game.

Invariably, a few suckers will bite on the lure and buy some shares in the stock; the sudden burst of interest in the otherwise dormant stock will tend to force the price upward, at which point the perp (or his fellow-conspirators) can sell their shares at a profit. This, of course, is the “dump” part of the game. Just as the flurry of buying forces the share price up, the flurry of selling will force it right back down again, usually to its original price (if not less). The perps have the suckers’ money, and the suckers have a bunch of low-performing, nearly worthless shares. Clever, huh?

In the USA, the pump-and-dump game is criminal securities fraud. The U.S. Securities and Exchange Commission (SEC) is responsible for policing the stock markets and dealing with pump-and-dump artists. The SEC’s website includes a useful guide to pump-and-dump and other risks of trading in microcap stocks.

The spam angle

It turns out that spam is an ideal vehicle for pump-and-dump fraudsters.

What distinguishes pump-and-dump e-mail from most other varieties of spam is the fact that the senders don’t expect any kind of direct response from you; they have no pills or porn or watches to sell, and no mortgage companies waiting for hot leads. All they want is to drop their “information” in your inbox in the hope that you’ll take action on your own. For this reason, stock spam can run with a much lower network profile than most other kinds of spam, and is consequently harder for providers and law-enforcement types to deal with.

In fact, these spams, like King Claudius’s sorrows (in Hamlet), come not single spies but in battalions. I’ll often get a dozen or more spams touting the same stock over the course of a week or so; the spams are often in a couple of different variations, so I suspect that more than one spammer may often be at work in a single scam.

On the other hand, stock spams by their nature are very easy for content-based spam filters to detect and detain, so the spammers have to use some tricks to get past these filters. In this regard, we’ll next take a look at a couple of representative examples.

This mail was sent from, part of a very small FTTP (“fiber-to-the-premises”) block that Verizon sold to someone called Nirmala Perumal in Tampa, Florida (one of the current world capitals of spam). Congratualtions, Nirmala: yours is the first spam I’ve received via Verizon FIOS.

A forged HELO (“verizon.net”) was used; and since no “real” intermediate mail hosts handled the message, this seems to be a direct-to-MX spam.

The message contains the stock pitch in the form of a block of plain ASCII text that has been base64 encoded (the odd-looking lines at the bottom of the message). There’s no technical reason to base64-encode plain ASCII text; what the spammer is doing here is simply hiding the content from lazy spam filters that don’t know how to do MIME decoding. Here’s what was disguised:

CALGARY, Alberta--(BUSINESS WIRE)--Oct. 31,
2005--Premium Petroleum, Inc. is pleased to
announce that it has initiated its Seismic
program on its Boyne Lake Gas Project. Due to
the channel sand nature of the geology at the
site, management has decided to shoot a seismic
program to assist in identifying the optimum
drill location on the subject lands. To this
end, a highly respected geophysical firm of
Petrel Robertson Consulting Ltd. has been
retained to design, oversee, and interpret a 3-
line 8 km seismic program. This program should
be completed and interpreted within the next 30
to 60 days, subject to equipment availability.

"The power of seismic is that it raises the
probability of success," commented Bruce
Thomson, President and Chief Executive Officer
of Premium Petroleum, Inc. "In this case from
an estimated 35% to an over 70%," concluded

The reason why the spammer felt compelled to obscure this message with base64 is that it is chock-full of red flags for content-based spam filters. The statement at the bottom is very typical of the kind of “boilerplate” disclaimer one sees in these messages, but note that the spammer has applied some “creative” spelling to many of the key words.

Stock pitch concealed in an image

Our next example uses a different approach to hiding the pitch: the spammer has concealed it within a GIF image. Even the best content-based spam filters can’t fish the text out of an image, so the message has a much better chance of getting through.

This spam was received from, yet another Verizon address; this one is from a DSL “pool” in Los Angeles, so this may be an instance of transmission by an open proxy or “zombie,” and direct-to-MX mailing in any case. A forged header line was added, pointing to an unknown host FLBPEHBK.carolina.net.

The body of the mail, which I have edited and doctored for brevity, is a MIME multipart message with three parts. It fits what has become a very familiar pattern for many types of spam these days:

Because the spammer has embedded the image in the message, and has linked to it using an “internal” cid: link (rather than the customary “external” http: link), he does not have to store the image on a remote server that could be detected and shut down. He’s also made your computer swallow a message that has been bloated up to nearly 29kBytes (in plain text, this mail probably would have been a quarter of this size or smaller).

Here’s the image that spammy wants so badly for you to see (NOTE: this GIF file may be malformed and possibly will not display in your browser):

Pretty professional-looking pitch, don’t you think? I’m not sure what caused the glitchiness at the bottom; it could be a problem with my decoding from base64, but it’s at least as likely that it was present in the original image.
