Hannaford Breach Included Clear Text Sent Via Fiber-Optic Cable
Written by Evan SchumanThe Hannaford data breach included payment information that was partly encrypted and partly clear text—and it was all transmitted over a private fiber-optic cable, according to a Hannaford official quoted in the Wall Street Journal.
This information—on top of the reports that Trojan Horse software was installed on 300 servers in 300 Hannaford stores–is painting a picture of a retailer that seemed to be following accepted security procedures. The story reported that the cyber-thief created software “intercepted the information as it went back and forth over a cable to a transaction processor in Denver. It was then transmitted to an Internet service provider somewhere outside the U.S.,” according to Hannaford marketing VP Carol Eleazer, who added that “it took a team of about 30 forensics experts and information technologists more than 10 days of round-the-clock troubleshooting to discover the malware.”
Cards issued by European banks when used online cross border don't usually support AVS checks. So, when a European card is used with a billing address that's in the US, an ecom merchant wouldn't necessarily know that the shipping zip code doesn't match the billing code.
