title: Meaning of =3D in malicious URLs
body: <p>My server logs show a many attempts to access non existing sides. These are the "usual" bots scanning for known vulnerabilities. Many of the URLs contain <code>=3D</code>, e.g.</p>
  
  <pre><code>/?q=3Duser%2Fpassword&amp;name%5B%23p=
  /user/register/?element_parents=3Daccou=
  /wp-admin/admin-post.php?swp_debug=3Dlo=
  </code></pre>
  
  <p><code>%3D</code> is the url encoded value of <code>=</code> so I would expect to find <code>%3D</code> within the URL but not <code>=3D</code>. However, <code>=3D</code> can be found all over the logs. What is the meaning of this?</p>
