Phishing
Description: Cyber criminals use deceptive emails, websites, or messages to trick users into providing their credit card information.
Defense:
– Education: Teach employees how to identify phishing scams.
– Email Filtering: Deploy advanced email filters to detect and block phishing emails.
– Two-Factor Authentication (2FA): Implement 2FA for an additional layer of security.
Skimming
Description: Skimming involves devices that capture card details from the magnetic stripe during swiping.
Defense:
– EMV Chips: Promote the use of EMV chip cards, which offer better security than magnetic stripes.
– Inspection: Routinely check ATMs and POS systems for skimming devices.
– Tamper-Resistant Terminals: Utilize card readers that are tamper-resistant.
Carding
Description: Fraudsters use stolen credit card details to make small online purchases, testing if the card is still active.
Defense:

– Address Verification Service (AVS): Confirm the cardholder’s billing address during transactions.
– Tokenization: Substitute card details with a unique token during transactions.
Man-in-the-Middle (MitM) Attacks
Description: Cyber criminals intercept and modify communications between the cardholder and the merchant.
Defense:
Encryption:
