Visa warns that hackers are scraping card details from gas pumps
Cybercrime groups are actively exploiting a weakness in gas station point-of-sale (POS) networks to steal credit card data, Visa has revealed. The company's fraud disruption teams are investigating several incidents in which a hacking group known as Fin8 defrauded fuel dispenser merchants. In each case, the attackers gained access to the POS networks via malicious emails and other unknown means. They then installed POS scraping software that exploited the lack of security with old-school mag stripes in card readers that can't read chips.
