AusweisApp TLS Certificate Revoked by D-Trust
Sector Threat Intelligence · 2 sources · Updated 2mo ago · First seen Sep 26, 2026

D-Trust, the Bundesdruckerei-operated certificate authority, revoked the X.509/TLS certificate for ausweisapp.bund.de on September 25. Browsers will no longer trust the revoked certificate, potentially presenting certificate-security warnings to users accessing the German electronic-ID application’s domain; two other TLS certificates for the domain reportedly remain valid.
The certificate revocation list cites “Privilege Withdrawn” as the reason. That status does not alone indicate private-key compromise: it can reflect unauthorized or improper certificate use, changes to certificate-holder information, or a certificate issued in error. The precise cause had not been publicly disclosed, and Bundesdruckerei had not responded to media inquiries.
