| | Verification Purpose | Example | |-----------------------------|---------------------------------------------------------------|--------------------------------------------------| | Banking alerts | Confirm alert is from the real bank, not a scammer | “Chase Verified: $500 charge at Target” | | Two-factor authentication | Ensure OTP originates from legitimate authentication service | “Your Google verification code: 123456” (verified) | | Healthcare appointment reminders | Prove message is from a clinic, not a phishing attempt | “Memorial Hospital verified: Your appt is 4/22” | | Personal messaging | Prevent man-in-the-middle attacks on chats | Signal “Safety number changed – verify contact” |
In advanced attacks (e.g., MFA bombing), an attacker triggers repeated legitimate 2FA verification messages. The user, annoyed, deciphers the stream as a “glitch” or “test” and finally approves one. Here, the verification is real; the context (multiple, unsolicited pushes) is the true signal. But few systems train users to decipher volume as a threat indicator.
