The New 'Cone of Silence', or The Death of Acoustical Ducting

Boston University researchers, Xin Zhang, a professor at the College of Engineering, and Reza Ghaffarivardavagh, a Ph.D. student in the Department of Mechanical Engineering, released a paper in Physical Review B demonstrating it's possible to silence noise using an open, ringlike structure, created to mathematically perfect specifications, for cutting out sounds while maintaining airflow.

"Today's sound barriers are literally thick heavy walls," says Ghaffarivardavagh. ...they are a clunky approach not well suited to situations where airflow is also critical...

They calculated the dimensions and specifications that the metamaterial would need to have in order to interfere with the transmitted sound waves, preventing sound—but not air—from being radiated through the open structure. The basic premise is that the metamaterial needs to be shaped in such a way that it sends incoming sounds back to where they came from, they say.

As a test case, they decided to create a structure that could silence sound from a loudspeaker. Based on their calculations, they modeled the physical dimensions that would most effectively silence noises... The metamaterial, ringing around the internal perimeter of the pipe's mouth, worked like a mute button. more

Corporate Security: Will Your "Secret" Status Hold Up in Court?

via Epstein Becker Green - Peter A. Steinmeyer
A federal judge in Chicago recently taught a painful lesson to an Illinois employer: even if information is sufficiently sensitive and valuable that it could qualify as a “trade secret,” it won’t unless the owner of the information took adequate steps to protect its secrecy. 

This doesn't qualify.

In a thorough opinion issued in the case, Abrasic 90 Inc., d/b/a CGW Camel Grinding Wheels, USA v. Weldcote Metals, Inc., Joseph O’Mera and Colleen Cervencik, U.S. District Judge John J. Tharp, Jr. of the Northern District of Illinois explained that “there are two basic elements to the analysis” of whether information qualifies as a “trade secret”:

(1) the information “must have been sufficiently secret to impart economic value because of its relative secrecy” and

(2) the owner “must have made reasonable efforts to maintain the secrecy of the information.” more

FutureWatch: Invisible-Light-Powered Eavesdropping Devices

Wi-Charge uses safe infrared light to deliver power from a distance. Our products provide enough power to charge a phone across a room, to power smart devices and enable new experiences. With Wi-Charge, mobile and IoT devices appear to charge autonomously. New applications open for homes, offices, factories and public spaces.

Battery-powered devices are portable, but battery capacity limits functionality and the need to replace batteries degrades the user experience. Moving wired devices, routing or hiding the power cords is a pain. Wi-Charge delivers 100x the power budget of battery solutions. With Wi-Charge, you can have the convenience of wire-free portability with a power budget approaching to a wired solution. more

Lots of good uses, and possibly some evil ones.

Electronic Footprint Army Boots Discovered

Hamas-run security forces at the Kerem Shalom crossing in the Gaza Strip have seized a shipment of army boots outfitted with tracking devices, Turkey’s state-run news agency Anadolu reported on Saturday, citing a security source in the coastal enclave.

Hamas security forces were carrying out “a precise inspection of the tracking devices in order to… understand how they work,” the security source said. more

Looks like the same technology as shoplifting tags and card-keys. Clever.

Book - JUDGEMENT by Joe Finder - Fast-Paced Thriller with Technical Surveillance Overtones

Just Released

JUDGEMENT by Joe Finder
Excerpt...
"It was nothing more than a one-night stand. Juliana Brody, a judge in the Superior Court of Massachusetts, is rumored to be in consideration for the federal circuit, maybe someday the highest court in the land.

At a conference in a Chicago hotel, she meets a gentle, vulnerable man and has an unforgettable night with him—something she’d never done before. They part with an explicit understanding that this must never happen again.

But back home in Boston, Juliana realizes that this was no random encounter. The man from Chicago proves to have an integral role in a case she's presiding over—a sex-discrimination case that's received national attention. Juliana discovers that she's been entrapped, her night of infidelity captured on video.

Strings are being pulled in high places, a terrifying unfolding conspiracy that will turn her life upside down. But soon it becomes clear that personal humiliation, even the possible destruction of her career, are the least of her concerns, as her own life and the lives of her family are put in mortal jeopardy.

In the end, turning the tables on her adversaries will require her to be as ruthless as they are..."

Smart Light Bulbs May Not Be a Bright Idea

Your discarded smart lightbulbs reveal your wifi passwords, because they are stored in the clear.

Not to mention, someone replacing your bulb and getting the password that way.

Yes, I know, the spy might not program the replacement bulb to operate like the old one. Dead give-a-way, right? My bet is that you'll think the bulb just forgot it's settings, or not notice at all.

This hack was publicized here, and originally researched here, if you want to know more.

Facilities Manager Alert: Your Smart Building May Start Doing Dumb Things

Researchers at enterprise security vendor ForeScout have warned that malware specifically targeting smart buildings is an inevitable next step given the rapidly expanding attack surface that building automation systems expose.

The operational technology researchers at ForeScout should know: they created proof-of-concept malware that revealed smart building vulnerabilities every business should be concerned about.

...just yesterday, Tenable Research revealed it had discovered several zero-day vulnerabilities in a premises access control system used by Fortune 500 companies. Among the many attack scenarios these vulnerabilities could facilitate was 'unfettered access to the badge system database' which in turn meant an ability to create fraudulent access badges and disable building locks. more

Hackers Now Banking on Two-Factor Authentication for Profit

Sophisticated hackers have long exploited flaws in SS7, a protocol used by telecom companies to coordinate how they route texts and calls around the world. Those who exploit SS7 can potentially track phones across the other side of the planet, and intercept text messages and phone calls without hacking the phone itself. 

This activity was typically only within reach of intelligence agencies or surveillance contractors, but now Motherboard has confirmed that this capability is much more widely available in the hands of financially-driven cybercriminal groups, who are using it to empty bank accounts. So-called SS7 attacks against banks are, although still relatively rare, much more prevalent than previously reported. Motherboard has identified a specific bank—the UK's Metro Bank—that fell victim to such an attack...

One source familiar with SS7 attacks across banks said the exploitation has targeted banks globally, but that American banks seem to be less impacted. more

Reader comment: "Please note the Motherboard reporter carefully differentiates between "sophisticated hackers" and "financially-driven cybercriminal groups".  I hope you'll consider being equally judicious in your own reporting and online comments."

Evil Child Watch Spies

In late 2017, the Norwegian Consumer Council published its audit of kids' smart-watches, reporting that the leading brands allowed strangers to follow your kids around and listen in on their conversations; a year later, Pen Test Partners followed up to see if anything had changed (it hadn't).

Now, a year and a half later, Pen Test Partners have done another security audit of kids' smart watches and you'll never guess what they found! Kids' smart-watches are still a dumpster-fire: anyone can access the entire database of kids' data, including "real time child location, name, parents details etc," and since most leading brands use the same back-end from Gator, virtually every kid's smart-watch is vulnerable. more
