Smishing and vishing are scams that target cell phones; vishing also targets land-line phones.

Similar to phishing, smishing is the act of sending malicious text messages to cell phones to trick the user into divulging credit card numbers, social security numbers, etc. Vishing is the act of calling cell phones and land-line phones to leave voice messages that potential victims need to take action about a phony event such as their bank account will be closed or there is a suspicious charge on their credit card. The attackers use automated dialing systems to call the phones. The potential victims are directed to go to a fake website or call a phone number where they will be asked to give sensitive information.

Phone users should never reply to any unsolicited messages.
