This will likely come as no surprise to many, but Spiegel International reports:
Donald Trump’s most important security advisers used Signal to discuss an imminent military strike. Now, reporting by DER SPIEGEL has found that the contact data of some of those officials, including mobile phone numbers, is freely accessible on the internet.
According to reporting by Patrick Beuth, Jörg Diehl, Roman Höfner, Roman Lehberger, Friederike Röhreke und Fidelius Schmid:
DER SPIEGEL reporters were able to find mobile phone numbers, email addresses and even some passwords belonging to the top officials.
To do so, the reporters used commercial people search engines along with hacked customer data that has been published on the web. Those affected by the leaks include National Security Adviser Mike Waltz, Director of National Intelligence Tulsi Gabbard and Secretary of Defense Pete Hegseth.
Most of these numbers and email addresses are apparently still in use, with some of them linked to profiles on social media platforms like Instagram and LinkedIn. They were used to create Dropbox accounts and profiles in apps that track running data. There are also WhatsApp profiles for the respective phone numbers and even Signal accounts in some cases.
As such, the reporting has revealed an additional grave, previously unknown security breach at the highest levels in Washington.
