Another good fake 2024-04-29T21:12:44+0200 true

This one is another good fake mail that does not look like spam at the first sight -- but in the end they're all the same mails with faked recipients/senders/links etc.

The mail body



                              Mit Drei immer bestens informiert.
                                  [1][DreiInfoConsumerKletterer]
                                        Lieber Drei Kunde,

              Ich hoffe, es geht Ihnen gut. Ich möchte Sie über ein wichtiges Update
           bezüglich Ihrer Telefonnummer informieren. Wir haben kürzlich festgestellt,
                  dass Ihre Nummer aufgrund einiger Änderungen in unserem System
                               irrtümlicherweise deaktiviert wurde.

            Um Ihren Telefondienst wiederherzustellen, bitten wir Sie, diese einfachen
                                      Schritte zu befolgen:

           Klicken Sie auf [2]Link. Dies wird Sie zu unserer Plattform weiterleiten, wo
                   Sie die Reaktivierung Ihrer Telefonnummer bestätigen können.


          Sobald Sie auf den Link geklickt und die Reaktivierung bestätigt haben, sollte
                     Ihre Telefonnummer in Kürze wieder betriebsbereit sein.


            Um Ihr Telefon zu reaktivieren, klicken Sie bitte auf den folgenden Link:



                [3]https://www.drei.at/selfcare/Verification.do?optInKey=id8630763



                Wenn Sie zusätzliche Unterstützung benötigen oder Probleme bei der
                       Reaktivierung Ihrer Nummer haben, zögern Sie nicht.



            Wir danken Ihnen für Ihre Mitarbeit und Ihr Verständnis. Wir sind hier, um
         Ihnen so schnell wie möglich bei der Wiederherstellung Ihres Telefondienstes zu
                                             helfen.

                                        Freundliche Grüße
                                      Ihr Drei Service-Team

"Undisclosed-Recipients" is used when the sender does not provide a recipient in the "To:" field but instead uses the "Bcc:" field.

The line X-Delivered-to shows the real recipient though.

Notes

The email went through some japanese network when it finally hit the mailservers of my mail provider.

Always check the destination of links in HTML mails! The link on line 78 for example looks like (re-formatted):

<div style="text-size-adjust: none; text-align: left;">
  <span style="font-size: medium;">
    <a href="https://wid.chh.mybluehost.me/website_7fb0c4ce/at/1">
    <span class="main-copy" style="line-height: 20px;">
      https://www.drei.at/selfcare/Verification.do?optInKey=id8630763
    </span>
    </a>
  </span>
</div>

Also look at the Subject -- it looks a bit disturbing:
