Stuxnet computer worm might target North Korea’s nukes

the North Korean control system “is dual use, also used by the petrochemical industry, but was the same as those acquired by Iran to run its centrifuges.”
Could Stuxnet Mess With North Korea’s New Uranium Plant? Wired.com. By Kim Zetter and Spencer Ackerman November 22, 2010 The Stuxnet worm may have a new target. While security analysts try to figure out whether the now-infamous malware was built to sabotage Iran’s nuclear program, North Korea has unveiled a new uranium enrichment plant that appears to share components with Iran’s facilities. Could Pyongyang’s centrifuges be vulnerable to Stuxnet?

While U.S. officials are trying to figure out how to respond to North Korea’s unveiling of a new uranium enrichment plant, there are clues that a piece of malware believed to have hit Iran’s nuclear efforts could also target the centrifuges Pyongyang’s preparing to spin.

Some of the equipment used by the North Koreans to control their centrifuges — necessary for turning uranium into nuclear-bomb-ready fuel — appear to have come from the same firms that outfitted the Iranian nuclear program, according to David Albright, the president of the Institute for Science and International Security and a long-time watcher of both nuclear programs. “The computer-control equipment North Korea got was the same Iran got,” Albright told Danger Room.

Nearly two months before the Yongbyon revelation, Albright published a study covering the little that’s publicly known about the North’s longstanding and seemingly stalled efforts at enriching its own uranium. (.pdf) Citing unnamed European intelligence officials, Albright wrote that the North Korean control system “is dual use, also used by the petrochemical industry, but was the same as those acquired by Iran to run its centrifuges.”

Energy efficiency – theme for July 2019

Energy efficiency represents the single largest potential contributor to global emissions reduction, according to the International Energy Agency (IEA 2017). It should be a key part of the global energy strategy, for several reasons:

It could reduce global electric demand by more than 20 per cent, based on current rates in the U.S. power sector, while maintaining high levels of services such as heating and lighting.
It avoids the need for increased energy, capacity and grid services, making it the least expensive way to decarbonise at scale.
It can reduce carbon dioxide emissions by billions of tonnes.

A dramatic example of the power of energy efficiency is lighting. In 2017 the United States passed the milestone of 1 billion LED and CFL lights installed, avoiding 142 million tonnes a year of carbon dioxide emissions, at a cost of about $7 per ton of avoided carbon dioxide. In contrast, the cumulative installed capacity of rooftop solar reached 8,000 MW in 2017, saving 8 million tonnes a year of carbon dioxide, at a cost of $360 per ton. Lighting efficiency thus yielded almost 18 times the avoided carbon dioxide, at about 2 per cent the cost per ton of rooftop solar.

Google provides another example of the power of energy efficiency. Its data centers now use 50 per cent less energy than the average data center, according to the company. Google also developed an improved chip, the TPU, which performs 83 times better than standard CPUs. The new chip allowed Google to reduce power consumption at its data centers by a factor of 30—far exceeding the effect on Google’s carbon footprint of all of the company’s renewable energy purchases. ” – John Woolard, Eco Business, 10 June 2019
