Attack types
스미싱 / 비싱 (Smishing / Vishing)
Definition
Phishing via SMS (smishing) or voice calls (vishing), often combined with email attacks.
For executives (CEO·CISO)
Attacks cross channels (email → SMS → a trust-building call); defending email alone gets bypassed. Commonly missed: weak identity checks at the help desk/call center let one phone call reset a password or MFA — harden human-facing social-engineering procedures.
