Smishing & 2FA Interception Defense: STIR/SHAKEN Caller ID Attestation & Out-of-Band Push Tokens
By Mobile Threat Intelligence & Defensive Architecture Review Board
Combating SMS social engineering: telecom STIR/SHAKEN cryptographic certificates, RCS verified sender badges, and replacing SMS OTPs with FIDO2 passkeys.
SMS-based phishing (smishing) remains the primary delivery mechanism for credential harvesters and mobile malware droppers.
1. Telecom & Device Defense Architecture
- STIR/SHAKEN Framework: Authenticates originating telephone numbers via digital certificates, labeling unverified spoofed calls and SMS with 'Spam Likely' warnings.
- Rich Communication Services (RCS) Business Messaging: Verifies corporate senders with cryptographic brand checkmarks, blocking unverified sender names.
- Passkey Migration: Transitioning enterprise systems from SMS 6-digit codes to WebAuthn cryptographic passkeys stored in biometric hardware enclaves.
