Data Sheet—Saturday, June 25, 2016 by Robert Hackett @FortuneMagazine June 25, 2016, 1:09 PM EDT E-mail Tweet Facebook Linkedin Share icons Putting aside Brexit for a moment, let’s review another major development in the realm of geopolitics this week. Perhaps you’ll recall that last fall, United States President Barack Obama and Chinese President Xi Jinping shook hands on a dubious cyber truce: They promised that neither nation would hack the other’s companies for financial gain. Fat chance, right? Skeptics (myself included) considered the treaty to be little more than an excuse for a photo opp—and, moreover, as a way for Xi to save face on the eve of his first state visit to the U.S. (Government officials were considering slapping sanctions on China for its colossal intellectual property theft at the time, a move that surely would have made for awkward dinner conversation.) Given the scale of China’s digital shoplifting, nobody this side of the Pacific seemed to think the entente would hold. Well, turns out China seems to be…keeping its promise! (That, or the country’s hackers have gotten way better at eluding detection.) So found cybersecurity firm FireEye, which released its discovery in a report earlier this week. The company said that, based on its data, the number of breaches attributable to China-based groups plummeted by 90% in the past two years. Yep, cue double take. I had a chance to chat with Laura Galante, director of threat intelligence at FireEye, as well as Kevin Mandia, the company’s recently appointed CEO, about the news. “We’re seeing compromises of networks still,” Galante told me, mentioning that its difficult to know whether the intruders are state-sponsored and whether their motives are economic rather than political or military. (The latter is still fair game, per the terms of the espionage deal). “What we aren’t seeing is data theft at such a volume as before.” Mandia, who took over as FireEye CEO this month, added that the decline in number of breaches doesn’t mean businesses should breathe a sigh of relief just yet, even though the news is positive. “The unfortunate reality is that you still have to build your moat of defend against the other threats that are still out there,” he said. Be assured: hackers still want your data. You can read the interview here. Enjoy the weekend, dear readers, with the relative peace of mind that China-based economic cyberespionage has dwindled. At least for now. More news below. Robert Hackett @rhhackett email@example.com Welcome to the Cyber Saturday edition of Data Sheet, Fortune’s daily tech newsletter.
