Retailer Shinsegae and 24 other South Korean companies have been breached, resulting in the theft of private data on 20 million customers.

"The breaches were discovered a few days ago, after the police arrested three South Korean nationals that were trying to sell the information (IDs, addresses, passwords, etc.) online," writes Help Net Security's Zeljka Zorz. "Supposedly, they didn't steal the data themselves but acquired it from some Chinese hackers, who are yet to be apprehended."

"Shinsegae apologized to its customers and said that as far as they are aware, no damages have been inflicted to any of the customers," Zorz writes.
