Sniffing in the dark
September 15, 2019
Credit card sniffers are relatively few lines of malicious code that are injected into payment pages of e-commerce sites. Sniffers copy input credit card information and send it to the attackers’ servers. These attacks are difficult to detect, as sniffers are generally small and stealthy, blending in with legitimate elements of a website. While making a purchase on a reputable site, an e-commerce client can unknowingly be victimized by this type of attack.
