The scariest tech of 2017, period, end of sentence

"While the smallest segment of this [hacked] information can cause utter chaos in a person's life, there seems to be no real consequences to... lax security resulting in theft," says contributor Charlie Osborne. "That's frightening."

"Love 'em, but they're in the hands of amateurs -- including me," CBSi distinguished lecturer David Gerwitz says about drones. "We'll see them drop out of the sky on people, drop payloads, spy, and otherwise cause constant trouble."

We're not along in fearing drones, by the way. They're a national-security concern, too. FBI director Christopher Wray told a US Senate panel that terrorist organizations have used drones to unleash attacks overseas.

"The expectation is it's coming here imminently," Wray said.

Oh: And the rest of America is spooked, too. According to a new survey, a drone swarm is the No. 1 technology fear of Americans, topping self-driving cars, self-learning computers, and "robots that teach each other."

"The WannaCry attack showed how easy it is for ransomware to bring things crashing to a halt, especially with the aid of self-propagating tools like EternalBlue," says senior reporter Danny Palmer.

Six weeks after WannaCry, the Petya cyberattack struck. "[It] showed that many just hadn't learned lessons from the previous outbreak," Palmer says. "Just imagine the havoc that can be caused if this careless attitude to device security is taken in an ever-more connected world."

"I'm really creeped out by proximity-based dating features, like Match.com's Missed Connections," says staff writer Stephanie Condon. "Sounds like a great stalker tool to me."

A 2015 study on dating-app privacy risks urged users to proceed with caution.

"I think about [the digital divide] whenever I go to a tech conference in San Francisco, and pass through the tents that line the streets between the Caltrain station and the Moscone Center," our Stephanie Condon says. "I worry about people who will be left out of a more connected society."

"Russia's fake-news machine" stands accused of inserting itself into elections in the United States, France, Germany, and elsewhere. Freelance blogger Jack Schofield fears the "troll invasion" has played a "significant factor in whole countries taking catastrophic political decisions."

US Senators investigating Russian meddling don't think "active measures" to incite "chaos" ended on Election Day 2016, and have asserted that "every campaign and every election official" should heed the threat of continued interference.

Make that, our "crappy" electrical infrastructure. That's how CBSi's David Gewirtz puts it when he explains why extreme-weather events, such as hurricanes, have the potential to "blast [us] back to the Stone Age."

The biometric technology is at airports, banks and soon, on your iPhone X. The growing use of facial recognition is a concern of our Stephanie Condon.

A just-released study confirms Condon is not alone in her fear: 40 percent of surveyed consumers think face-ID programs are "too risky and unknown for them to use right now," CNBC reported.

"I see a towering disaster in the ICO (Initial Coin Offering) sector," says ZDNet contributor Tom Foremski. "Billions are being invested in technology startups of dubious qualifications and abilities... It's wide open to abuse."

Per Foremski, an ICO collapse would also hamper legitimate developments in cryptocurrency, and, in turn, hurt the developing world's ability to access small loans and e-commerce.

As recently noted by senior reporter Danny Palmer, "billions" of Internet of Things (IoT) devices have hit the market, and settled into our homes and offices "with almost no thought put into cybersecurity."

ZDNet UK reviews editor Charles McLellan says he fears IoT cyberattacks could devastate "critical infrastructure in healthcare, energy, transport, manufacturing" and other sectors.
