The bloom began falling off the blockchain rose a few years ago, as companies conflated the technology with the cryptocurrency frenzy. In a handful of sectors, however, companies continued to explore how blockchain could benefit them.

Now organizations in sectors well beyond the pioneers in finance are investing in blockchain to protect data, decentralize processes and facilitate asset and data transfer.

“It’s an appealing model for many sectors, promising transparency and trust as it helps make value exchange possible,” says a SmartBrief article. Although focusing mostly on the financial sector, which is where blockchain found its earliest uses, the article mentions the steady creep of the technology into other industries and even slowly becoming commoditized as “blockchain as a service.”

“Amazon and Microsoft both currently offer BaaS, and enterprises as well as startups are taking advantage of it,” says SmartBrief. Citing a Gartner survey of CIOs, the article notes that “60% expected their firms to start or continue adopting blockchain-based technology between now and 2023.”

Earlier this year, Deloitte issued a blockchain trends report. Besides describing the evolving technology and the features each different approach offers, Deloitte found that some of the fastest growth in blockchain investments was coming in such unexpected industries as professional services – a sector that includes the staffing and employment industry – and energy and resources. In each of those 38% and 43% respectively of the firms surveyed were spending at least $5 million each on blockchain initiatives.

Not unexpectedly, the largest percentage of businesses investing in blockchain were in technology, media and telecom.

“More organizations in more sectors — such as technology, media, telecommunications, life sciences, health care, and government — are expanding and diversifying their blockchain initiatives,” Deloitte observes.

Like the financial sector, life sciences and health care deal with highly sensitive medical data they must protect or face legal consequences. Those two sectors are where blockchain “can have a more immediate and meaningful impact,” says Deloitte. They are in an industry, the report explains, “In which data transparency, speed of access, immutability, traceability, and trustworthiness can provide the information necessary for life-altering decisions.”

Interestingly, Gartner assigns a similar importance – not life or death, but still vital – to blockchain’s value to media.

“Organizations and governments are now turning to technology to help counter fake news, for example, by using blockchain technology to authenticate news photographs and video, as the technology creates an immutable and shared record of content that ideally is viewable to consumers,” Gartner said.

As companies increasingly see how blockchain can work for them, and, as SmartBrief observes, with issues of interoperability and standards being worked out and “well-known financial firms and governments” becoming ever more involved, blockchain is fast becoming “more than a passing trend.”

Researchers Hack Computer Fan. Seriously!

doesn’t involve exploiting bugs or vulnerabilities in software. Instead, they found a way to do it by controlling a computer’s cooling fan.

Amazingly, they found hackers could encode stored data into fan vibrations by imperceptibly slowing down or speeding up the fan’s rotation. The fan causes the computer itself and the surface it’s on to vibrate and these vibrations can be picked up by a smartphone and then retrieved by a hacker.

“We observe that computers vibrate at a frequency correlated to the rotation speed of their internal fans,” lead researcher Mordechai Guri told Tech Xplore. “These inaudible vibrations affect the entire structure on which the computer is placed.”

“The malware in question doesn’t exfiltrate data by cracking encryption standards or breaking through a network firewall,” he said. “Instead, it encodes data in vibrations and transmits it to the accelerometer of a smartphone.”

While the process of transmitting the data is extremely slow, and therefore not likely to be adopted by hackers (spy services maybe?) it is yet another demonstration of how it is possible to access a computer that is air-gapped, meaning it is isolated and not connected to the internet.

Guri is head of R&D at the univerity’s Cyber-Security Research Center. He and his team specialize in finding ways to access data from highly secure systems and devising methods of protecting against the threats.

In the case of the fan vibration hack, a simple method of protecting against it is to make the fan speed unchangeable.

Happy SysAdmin Appreciation Day!

Behind every computer network is a person or a team you may have never met, yet it’s thanks to them that every email you write is sent, every file is there when you need it and every report you print gets printed.

These are the system administrators. They’re the ones who keep the computer system running. They update the programs and make sure the virus protection is still protecting.

When a new employee starts, who wires up their cubicle and gets them a login? You got it, a sysadmin.

When the COVID-19 pandemic forced businesses to have everyone work from home, sysadmins made it happen.

So unsung are these heroes of the network that it took a lone admin to create System Administrator Appreciation Day. 21 years ago Ted Kekatos had just finished installing new printers when he came across an ad for the very same printer. It showed a sysadmin with a grateful group of employees showering him with fruit baskets and flowers and wine. As a joke, he showed the ad around, then created a website and began promoting sysadmin day.

The day has grown so popular that besides the website Kekatos still runs there are dozens of video tributes on YouTube. There’s even a musical.https://www.youtube.com/embed/M32SJ2GGX3Q?feature=oembed

Besides sending your sysadmin a Happy System Administrator Appreciation Day message, take a hint from Ted Kekatos and gift your admins with ice cream and cake, cookies (chocolate, naturally) or cases of Monster, Dr. Pepper and Mountain Dew.
