Hey folks in infosec,

could you give me some material (if possible ready for management digestion) why TLS interception is an inherently bad thing that should stop _now_?

Things like weakening security, breaking pinning, deprecation in TLSv1.3, ...

@pake_preacher : I forgot the details of PAKE and SRP, but in the end the most secure client authentication requires:

1️⃣ Strong, long term, human comprehensible, *serving endpoint* authentication;
*AND*
2️⃣ TLS channel binding (enforcing known endpoints).

(Apart from those, both serving endpoint AND client MUST be trustworthy).

🚨 The -corrupt- CA/B forum breaks 1️⃣ by:
a) Advocating anonymous Domain Validated certificates, which render secure account creation IMPOSSIBLE;
b) Continuously decreasing certificate lifetime.

🚨 Furthermore, "legitimate" MitM's * break 2️⃣.

* Man in the Middle, like on-device virusscanners and firewalls that "open" TLS tunnels (both requiring installation of a dedicated root certificate) and proxies such as (definitely not limited to) Cloudflare and Fastly.

😱 Passkeys enforce NEITHER 1️⃣ NOR 2️⃣.

😱😱 Worse, because passkeys (or FIDO2 hardware keys) can be easily irretrievably "lost", servers typically provide WAY EASIER phishable authentication methods (such as "rescue codes").
