“Months before its technology became the centerpiece of Samsung’s new mobile payment system, LoopPay, a small Massachusetts subsidiary of the South Korean electronics giant, was the target of a sophisticated attack by a group of government-affiliated Chinese hackers,” Nicole Perlroth and Mike Isaac report for The New York Times. “As early as March, the hackers — alternatively known as the Codoso Group or Sunshock Group by those who track them — had breached the computer network of LoopPay, a start-up in Burlington, Mass., that was acquired by Samsung in February for more than $250 million, according to several people briefed on the still-unfolding investigation, as well as Samsung and LoopPay executives.”

“LoopPay executives said the Codoso hackers appeared to have been after the company’s technology, known as magnetic secure transmission, or MST, which is a key part of the Samsung Pay mobile payment wallet that made its public debut in the United States last week,” Perlroth and Isaac report. “Both LoopPay and Samsung executives said they were confident that they had removed infected machines, and that customer payment information and personal devices were not affected. They added that there was no need to delay the introduction of Samsung Pay, which had its debut in the United States last week after executing more than $30 million worth of purchases in South Korea.”

“But two people briefed on the investigation, as well as security experts who have been tracking the Codoso hackers as they have targeted hundreds of victims around the world, said it would be premature to say what the hackers did and did not accomplish since they were discovered in August,” Perlroth and Isaac report. “To start, the hackers were inside LoopPay’s network for five months before they were discovered. And the Codoso Group is known for maintaining a hidden foothold in its victims’ systems. Security experts say the group’s modus operandi is to plant hidden back doors across victims’ systems so that they continue to infiltrate their networks long after the initial breach.”

“After a similar attack by another Chinese state-affiliated hacking group on the U.S. Chamber of Commerce in 2011, the chamber believed it had rid hackers from its network only to discover months later that an office printer and even a thermometer in one of its corporate apartments were still sending information back to computers in China,” Perlroth and Isaac report. “Samsung introduced Samsung Pay in the United States just 38 days after LoopPay learned it had been breached. On average, it takes 46 days before an attack by hackers can be fully resolved, according to the Ponemon Institute, a nonprofit that tracks breaches. But the time to fix the damage is typically much longer in cases of sophisticated Chinese hackings like the one at LoopPay.”
