title: What's the SQL significance of 0x5E5B7D7E?
body: <p>Looking through some apache logs, I've run into the following pattern several times (URL decoded):</p>
  
  <pre><code>GET /foo.php?id=1 and union select 0x5E5B7D7E,0x5E5B7D7E,0x5E5B7D7E,... --
  </code></pre>
  
  <p>Clearly this is an SQL injection attempt. But why the constant shown above? I can't see how it could be particularly significant, though it seems to appear quite frequently.</p>
  
  <p>For what it's worth, the above constant maps to the following ASCII characters: "<code>^[}~</code>", or "<code>~}[^</code>" if you reverse the byte order. The value in decimal is <code>1,583,054,206</code>, in octal it's <code>013626676576</code>. The code doesn't seem to map to a useful sequence of x86 instructions.</p>
  
  <p>A Google search for the number reveals simply the remnants of attempts at using the same SQL injection attack on other sites -- no information about the attack itself.</p>
  
  <p>Anyone have any insight?</p>
