Bundestag President Klöckner recommends MPs switch from Signal to BSI-certified Wire, citing phishing resistance via email-only registration.
Key Takeaways
Wire Bund just received BSI approval for VS-NfD classified data, valid through end of 2028, pending post-quantum cryptography additions.
Email-only registration hides the identifier from third parties; no phone number exposed, reducing a common phishing attack surface.
CDU/CSU deputy leader Lindholz calls for an outright Signal ban for MPs and staff, a position security experts reject as misguided.
Post-quantum methods are still missing from Wire Bund, which is why the BSI certification carries a hard 2028 expiry.
Experts stress the human factor: guessable official parliamentary email addresses remain a viable phishing vector regardless of messenger choice.
Hacker News Comment Review
Commenters question why Bundestag administration labels Signal a “commercial platform” given its nonprofit structure, suggesting the framing may be political rather than technical.
The core skepticism: swapping Signal for Wire does not obviously reduce phishing risk, since phishing attacks credentials, not the messenger’s architecture.
Notable Comments
@internet_points: “ditching Signal because of the possibility for phishing seems very odd” – targets the logical gap between the threat model and the policy response.
