Spam2006スパマーの逆襲――進化するアンチ・アンチスパム (1/2) (ITmediaエンタープライズ) 

 この画像は、私の元に届いた英文のspamです。spamフィルタをくぐり抜けるためにさまざまな仕掛けをしてあります。

 まず、本文には英語の文章が書かれていますが、意味がありそうで全くありません(私が読めなかったわけではないです)。

 受信者に読ませるのは画像の方です。本文しか判定しないspamフィルタを通過するために画像中に文章を記述する手法は少し前からありました が、最近のspamフィルタは、画像を解析して言葉を探し出します。そこでこの画像では、解析させないために色を変えたり並びを崩したりしています。

 で、その結果がこれです。
 内容は、ある銘柄の株価が上がるから買え、というものです。これを真に受けた人が何人か株を買うと本当に値が上がるので、その時にspammerがその株を売って儲ける、という仕組みらしいです。

(「ポンプ&ダンプ詐欺」と言うらしいです。詳しくは次の記事を。
ソフォスがスパム送信国ワースト12公表、画像スパムの増加なども指摘 (INTERNET Watch))

 ていうかどう見ても「怪文書」なんですが、誰が本気にするんでしょうか(笑)

 一応小さい字で本文も載せておきましょう。暇な人は解読してみてください。

And all I have to say about that musement?
And if you've ever seen an eight-year-old cry in a way that is truly unsympathetic, well, you've known my pain. Go to take my life in my hands, is the answer.
"That pretty much covers everything but books and knitting! Much to my dismay, all of those markets were up a few bucks.
" And when I muse, sometimes I consider the possibility, think about looking for a condo in Reston or a home in Sterling.
It's an altered paradise, a paradise full of tiny scraps of construction paper, discarded toys, single dirty socks, piles of spelling homework. They fight over the biggest portion of dessert, over who gets to wear the desirable hat, over who can convince me to carry her bag home from school.
They are affectionate and desperate for attention.
Hurray for the timeless, old-world, switchless knitting needles. And never more so in the fall. And there is a little sidewalk on the receiving end of each corner. They fight over where each gets to stand while I make cookies.
But if someone takes away my challenge? Some might even call me over-prepared.
Their flight was overbooked, and despite confirmed reservations, the Aldapes were involuntarily bumped from the first leg of their flight. Now you're on your own, you crazy person.
Let's just hope and pray that my bosses will be so pleased with my amazing ability to produce great things while telecommuting, that they never even think of such an offer.
I consider the wonders of Great Falls, through which I spent many a lovely mountain bike ride in the crisp, lovely fall.
"Mom said we are going to move to Taylor's house next week!
He quickly called to book the trip, looking forward to the comfortable resort accommodations, free breakfasts and special cruise outing promised in the fax. Are your fingers itching at your checkbook, or your paypal account?
Maybe it was a good idea.
If you had to wait another minute something embarrassing was going to happen? Their flight was overbooked, and despite confirmed reservations, the Aldapes were involuntarily bumped from the first leg of their flight.
Lots of wealthy hip folks, many of whom I've grown to adore.
If you want to go to the trail? and so so many pillows on the beds.
AX, ended exclusive talks with BlueScope Steel over potential asset sales.
Later today I'll post a tutorial, and photos will come soon. They truly love school, and learning, and want so much to please everyone. Let's just hope and pray that my bosses will be so pleased with my amazing ability to produce great things while telecommuting, that they never even think of such an offer. Are your fingers itching at your checkbook, or your paypal account?
Maybe we could live in Georgetown, I think, or Arlington. "In fact, anything you have with an 'on-off' switch needs to be turned to the 'off' position.
