Blind Double Encoding

Hmm...
an HTML document encoded in base64 with a snippet of javascript encode it hexidecimal.

This may not have been the first time I've seen this.

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:
