How Vishing Scams Work
Vishing scams often begin with a phone call from an unknown number. The caller may use tactics such as urgency or fear to pressure the victim into divulging information. For example, the scammer might claim that there has been suspicious activity on the victim's bank account and immediate verification is required.
A typical vishing scenario involves the following steps:
- Initiation : The scammer contacts the victim, posing as a credible source.
- Manipulation : Through skilled communication, the scammer convinces the victim of the legitimacy of their claims.
- Extraction : The victim is persuaded to provide personal information or perform an action, such as transferring money.
