Renault and Nissan are among the businesses affected by massive ransomeware attack

SINGAPORE/TORONTO, May 14 (Reuters) - Technical staff scrambled on Sunday to patch computers and restore infected ones, amid fears that the ransomware worm that stopped car factories, hospitals, shops and schools could wreak fresh havoc on Monday when employees log back on. Cybersecurity experts said the spread of the virus dubbed WannaCry - "ransomware" which locked up more than 200,000 computers - had slowed, but the respite might only be brief. New versions of the worm are expected, they said, and the extent of the damage from Friday's attack remains unclear. Infected computers appear to largely be out-of-date devices that organizations deemed not worth the price of upgrading or, in some cases, machines involved in manufacturing or hospital functions that proved too difficult to patch without possibly disrupting crucial operations, security experts said. Marin Ivezic, cybersecurity partner at PwC, said that some clients had been "working around the clock since the story broke" to restore systems and install software updates, or patches, or restore systems from backups. Microsoft released patches last month and on Friday to fix a vulnerability that allowed the worm to spread across networks, a rare and powerful feature that caused infections to surge on Friday. Code for exploiting that bug, which is known as "Eternal Blue," was released on the internet in March by a hacking group known as the Shadow Brokers. The group claimed it was stolen from a repository of National Security Agency hacking tools. The agency has not responded to requests for comment. Hong Kong-based Ivezic said that the ransomware was forcing some more "mature" clients affected by the worm to abandon their usual cautious testing of patches "to do unscheduled downtime and urgent patching, which is causing some inconvenience." He declined to identify which clients had been affected. The head of the European Union police agency said on Sunday the cyber assault hit 200,000 victims in at least 150 countries and that number will grow when people return to work on Monday. "The global reach is unprecedented ... and those victims, many of those will be businesses, including large corporations," Europol Director Rob Wainwright told Britain's ITV. "At the moment, we are in the face of an escalating threat. The numbers are going up, I am worried about how the numbers will continue to grow when people go to work and turn (on) their machines on Monday morning." MONDAY MORNING RUSH?

Nissan's Le Mans-bound ZEOD RC electric racecar nearing completion [w/video]

Nissan is working away on its ZEOD RC (Zero Emission On Demand Racing Car) which is still on pace for a Le Mans arrival in 2014. As of right now, the DeltaWing-shaped car's carbon-fiber tub and chassis have been completed. The next step will be installing the twin electric motors and fitting the seat of driver and GT Academy winner Lucas Ordóñez. If the current schedule sticks, the zero-emissions racer will hit a UK track for test laps in September.
But while those initial shakedown laps will be under full electric power, it's unclear whether the setup fielded in the UK will survive until Le Mans. Nissan itself says that it will be testing a number of "electrified" drivetrains ahead of the 2014 24 Hours of Le Mans, which is a significant departure from race car design - usually, the teams know what's powering their car before they start building it.
"Just developing a single powertrain option in only 12 months would be a mammoth task but we're looking to carefully examine a number of options to ascertain which will be best suited for Le Mans," said Darren Cox, Nissan's global motorsport director. Take a look below for a video and press release from Nissan documenting the ZEOD RC's build process.

In his own words: Carlos Ghosn on why EVs rule

That's a nice little dig at hydrogen fuel cell technology, Mr. Ghosn. The Nissan chief, long a champion and heavy-duty investor of electric-vehicle technology, wrote an essay on his LinkedIn Influencer page on why EVs are the theoretical wave of the future. It's obviously not an unbiased opinion, but he makes his points clearly. Ghosn points out that "refueling" costs per mile for EVs are about 70 percent less than gasoline and more than 60 percent less than hybrids. He cites the rapidly growing network of plug-in vehicle charging stations that are eliminating "range anxiety" with at least some folks, and notes that the fastest growing US plug-in vehicle market is, of all places, Atlanta. Additionally, Ghosn, near the bottom of the post, says that a plug-in vehicle charging station can be deployed for as little as $2,000, while building a hydrogen station costs about $2.5 million. Pretty clever. Nissan's sales numbers appear to give Ghosn's confidence some clout. Through November, sales of the Leaf in the US surged 35 percent from a year earlier to more than 27,000 units. Globally, Nissan says the Leaf's sales are up 20 percent this year. Check out Ghosn's own words below. Zero-Emission Cars: Both Consumers and the Environment Win Last month, the Renault-Nissan Alliance sold its 200,000th zero-emission car. The Nissan LEAF, which we launched four years ago, is by far the top-selling electric vehicle worldwide. Sales are up 20 percent this year. Together with the Renault ZOE and other zero-emission vehicles in our lineup, Renault-Nissan's EVs have been driven about 4 billion kilometers – enough to circle the earth 100,000 times. They are the world's first and most successful mainstream, mass-marketed EVs. Why are more people switching to EVs? The reasons are clear: EVs are convenient: They can be refueled at home or at the office from multiple energy sources, including the increasing amount of clean energy from solar or wind power. Imagine never stopping at a gasoline service station because you wake up to a "full tank" every day. This is one of the top things EV owners enjoy about their cars. EVs are economical: Even with gasoline prices falling, Consumer Reports recently estimated operating costs of a Nissan LEAF in the United States at 3.5 cents a mile, compared with 11.9 cents for a subcompact gasoline car or 8.6 cents for a hybrid. EV owners typically save on their insurance policies, because insurers view EV drivers as a lower risk.
