When I&#8217;ve seen hide-the-file-in-an-image-and-post-it-to-a-newsgroup used in a network TV spy show, you know it&#8217;s old hat already. But the idea of <a href=\"http:\/\/www.spammimic.com\/\">encoding a message so that it looks like a typical spam message<\/a> and then sending that from forged address? That&#8217;s the brilliantest example of hiding in plain sight I&#8217;ve seen in ages. And probably the best confidentiality-without-encryption thing I&#8217;ve read since <a href=\"http:\/\/people.csail.mit.edu\/rivest\/Chaffing.txt\">Rivest&#8217;s chaffing and winnowing paper<\/a>.<\/p>\n<p><!--more-->I&#8217;m sure the implementation could be improved in lots of ways, and yes, it&#8217;s really only useful for very short messages anyway, but what a clever idea. <\/p>\n<blockquote>\n<pre>Dear Decision maker , We know you are interested in \r\nreceiving cutting-edge intelligence .
