<p class="MsoNormal"><span style="font-size:11.0pt">Not sure if this is the right place to send this, but I figured I’d start here since keys.gnupg.net seems to be hardcoded as a default in the source code for GnuPG.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">The company I work for leverages Palo Alto products for security, and we recently observed that keys.gnupg.net was not resolving properly. After digging into it, we discovered that Palo Alto is flagging keys.gnupg.net
as a Malware site.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">I’ve gone ahead and submitted a request for them to reclassify it as a non-malicious “Computer and Internet Info,” but that doesn’t exactly answer
<i>_why_</i> it was flagged. And it looks like they may have just changed it while I was in the process of writing this email (can be checked at
<a href="https://urlfiltering.paloaltonetworks.com/query/">https://urlfiltering.paloaltonetworks.com/query/</a> ).<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt">I did observe that at least one of the pool members seems to not be configured properly (if I do a ‘curl -k -H 'Host: http-keys.gnupg.net'
<a href="https://37.191.226.104">https://37.191.226.104</a>’ it displays a busted Matomo page).<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">And I’m left wondering if one of the pool members was serving up something that caused Palo Alto to flag keys.gnupg.net.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Oddly enough, neither hkps.pool.sks-keyservers.net nor sks-keyserver.net was blocked.<o:p></o:p></span></p>
