Reverse Captcha


Captcha, should you forget, is "Completely Automated Public Turing test to tell Computers and Humans Apart".

So, Spammers are trying to get the human part, not the "computer" part. Yes many many anti-spam tools will check your text thoroughly, but images - that can be tricky. So as might be expected, spammers from time to time attempt this. The image on the right is such an example.

Notice how nicely the letters (fonts) curve the page with the drug names. Notice the clear instructions on what to do. Notice the bright clear red arrow.

Apparently, asking someone to type versus click is a big deal. Otherwise I might see more of these than once a year. Otherwise this spam deserves little notice. Then again, you never know.

Disposable-Domains?

I received the article below, but it's hardly worth more than "press release" status. It's difficult to say what spammers do with their domains. No one has done an analysis of cost-to-purchase vs. profit-margins. In fact, from my own records 24-48 hours is about the most use spammers can make of open domains. Beyond that it must still be profitable to do this.

Any way here is that article, and it's link:

It's a phishing time of the year.

The latest in phishing, likely to infect the unsuspecting, is the follow.

>Dear taxpayer,The Federal income tax is a progressive tax, meaning that the more you earn, the higher your tax rate. Your tax rate depends not just upon your taxable income, but also upon your filing status (single, married filing jointly, etc.).You're in a higher tax bracket because:- your annual income for the last tax year has increased.Please review your annual tax report immediately


Life is marvelous. The link is in .kr (south korea).
