The term "vishing" is a socially engineered technique to gain access to private and personal financial information from consumers using the telephone network. The term comes from combining "voice" with "phishing," which are online scams that get people to give up personal information. Vishing is typically used with Caller ID spoofing. Spoofing is a situation in which one person or program successfully masquerades as another by falsifying data and thereby gaining an illegitimate advantage. The number on the caller ID is a spoofed ID, which means the fraudster is using someone else’s ID for this scam.
While consumers have learned to be suspicious of phishing scams that involve solicitations for personal financial information directly over the internet, they are still easily persuaded to divulge that information when called directly or when an email instructs them to call a specific number.
