📚 Visa Warns That Hackers Are Scraping Card Details From Gas Pumps

Visa has issued a statement warning consumers that cybercriminals are actively exploiting a weakness in gas station point-of-sale (POS) networks to steal credit card data. Engadget reports: 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 stripe cards that lack a PIN code. The hack doesn't appear to affect more secure chip-and-pin cards, but not all consumers have those, so service stations often work with mag stripe readers, too. The data is apparently sent in an unencrypted form to the vendor's main network, where the thieves have figured out how to intercept it. The other problem is that the POS systems aren't firewalled off from other, less critical parts of the network, allowing thieves to gain lateral access once the network is breached. There's not much cardholders can do to avoid the attacks, but Visa has advised fuel merchants to encrypt data while it's transferred or use a chip-and-PIN policy.
