Think Your Smart Speaker is Spying On You... get Paranoid

(Note: As of this date the manufacturer is only accepting pre-orders. Gauging demand before going into production is not uncommon. The following is just an interesting bit of news; not a product endorsement. Also, it might be an April Fool's prank.) 

Their headline reads, "Blocks smart speakers from listening, while keep them voice-activated. Just say "Paranoid" before your usual commands." more

"How?" ...you may ask.

A. In one of three ways.

1. The BUTTON model begins with the mute button pressed.  When it hears you say, "Paranoid" it presses again, thus letting your next command to pass through. After your command is finished it re-mutes with another press.
2. The HOME model (it appears) uses ultrasound to block the speakers microphones. Click here to learn how ultrasound blocking works. The volume needed for this application is very low so it shouldn't be a health risk.
3. The MAX model requires you sending them your smart speaker so they can physically install their solution. People who use this option are not true paranoids. True privacy paranoids would be afraid the unit might come back, bugged!

Guest Wi-Fi Access Comes with Risks for Organizations

Reported this week: A convicted sex offender downloaded indecent child images at a hostel where he was staying after using another resident's wi-fi code. more

In this case, a stolen access code was used to gain access. In many organizations the same guest code is given out to all guests. Sometimes it is even posted. Often it is never changed. Once the password is out, there is no telling who will access the system, or when, or for what purpose.

Downloading illegal images is only one of many guest access risks.

While hiding behind a reputable IP address unauthorized and anonymous "guests" can also conduct: drug transactions, video voyeurism, blackmail, financial scams, hacking, and more. The finger points at the organization's network. They might be legally held responsible. And, these are just the outward facing threats. Guest access can also be a pivot point to internal information theft.

Take this 15 second assessment.
Does your organization...

• Provide guest Wi-Fi access?
• Does guest access use the organization's network?
• Is access unencrypted?
• Do all guests use the same password?
• Is the password posted anywhere, as in a conference room?
• If posted, can it be seen from outside with binoculars or a drone?
• Has the password remained the same for over a month? 

If you said yes (and/or not sure) three or more times your organization needs a Wi-Fi Security Analysis.

Legal defense is expensive. Reputational damage is hard to quantify. A proactive professsional analysis is easy. Reduce risk and keep profits where they belong, in the bottom line.

The Potato Chip Bag Spy

Back in 2014, the potato chip bag became an audio eavesdropping device...
Want to listen in on a juicy conversation? Researchers from the Massachusetts Institute of Technology, Microsoft, and Adobe have designed an algorithm that can pick up conversation by analyzing the vibrations from speech as they ripple through a potato chip bag, MIT News reports. more

In 2020, the potato chip bag became a visual eavesdropping device too...
Mirrors aren't the only shiny objects that reflect our surroundings. Turns out a humble bag of potato chips can pull off the same trick, as scientists from the University of Washington, Seattle have made it possible to recreate detailed images of the world from reflections in the snack's glossy wrapping.

The scientists took their work a step further by predicting how a room's likeness might appear from different angles, essentially "exploring" the room's reflection in a bag of chips as if they were actually present. This is analogous to a classical problem in computer vision and graphics: view synthesis, or the ability to create a new, synthetic view of a specific subject based on other images, taken at various angles. more

Bosses Panic-Buy Spy Software...

... to keep tabs on remote workers.

“Companies have been scrambling,” said Brad Miller, CEO of surveillance-software maker InterGuard. “They’re trying to allow their employees to work from home but trying to maintain a level of security and productivity.”...

“It’s not because of lack of trust,” Miller said, who compared the software to banks using security cameras. “It’s because it’s imprudent not to do it.” more

Being Zoom'ed on Zoom has Organizations Worried, or they should be...

...experts warn that a rush to hold virtual meetings through Zoom, which has close to 13m monthly active users, could pose security risks.

The threat is so significant that British Ministry of Defence staff were told this week that the use of Zoom was being suspended with immediate effect while "security implications" were investigated.

The biggest worry is that a sudden reliance on Zoom could allow opportunistic hackers to quietly observe video calls as executives are focused on responding to the spread of coronavirus.

...the idea of strangers barging into virtual meeting rooms should raise alarm. more

Online Zoom classes were disrupted by individuals spewing racist, misogynistic or vulgar content. Experts say professors using Zoom should familiarize themselves with the program's settings. more

 

Mysterious Hacker Group Eavesdropping on Corporate Email & FTP traffic

Since at least early December 2019, a mysterious hacker group has been taking over DrayTek enterprise routers to eavesdrop on FTP and email traffic inside corporate networks...

Instead of abusing the device to launch DDoS attacks or re-route traffic as part of a proxy network, the hackers turned into a spy-box...

...researchers didn't speculate why hackers were collecting FTP and email traffic. But speaking to ZDNet over the phone, a security researcher pointed out that this looked like a classic reconnaissance operation...

"It's obvious they're logging traffic to collect login credentials for FTP and email accounts," the researcher told ZDNet. "Those creds are flying unencrypted over the network. They're easy pickings." more

BBC Spycam Documentary

Coronavirus Surveillance Escalates, Personal Privacy Plummets

Tracking entire populations to combat the pandemic now could open the doors to more invasive forms of government snooping later.

...government agencies are harnessing surveillance-camera footage, smartphone location data and credit card purchase records to help trace the recent movements of coronavirus patients and establish virus transmission chains...

...authorities are analyzing location data transmitted by citizens’ mobile phones to determine how many people are obeying a government lockdown order and the typical distances they move every day. About 40 percent are moving around “too much,” an official recently said.

...internal security agency is poised to start using a cache of mobile phone location data — originally intended for counterterrorism operations — to try to pinpoint citizens who may have been exposed to the virus...

...ratcheting up surveillance to combat the pandemic now could permanently open the doors to more invasive forms of snooping later. It is a lesson Americans learned after the terrorist attacks of Sept. 11, 2001, civil liberties experts say. more

Remote Work, Security & Is Your Office Being Bugged While You're Home

It's a rule of thumb in cybersecurity that the more sensitive your system, the less you want it to touch the internet. But as the US hunkers down to limit the spread of Covid-19, cybersecurity measures present a difficult technical challenge to working remotely for employees... In some cases, working from home isn't an option at all...

Late last week, the US government's Cybersecurity and Infrastructure Security Agency issued an advisory to critical infrastructure companies to prepare for remote work scenarios as Covid-19 spreads...

But cybersecurity consultants who actually work with those high-stakes clients—including electric utilities, oil and gas firms, and manufacturing companies—say that it's not always so simple. For many of their most critical customers, and even more so for intelligence agencies, remote work and security don't mix. more

Quote of the Week

"Organizations' ham-fisted operational changes due to the novel Coronavirus will create a field day for practitioners of espionage--industrial and otherwise."

Surveillance App Reworked for Coronavirus Alerts

Health officials in Britain are building an app that would alert the people who have come in contact with someone known to have the coronavirus. The project aims to adapt China’s tracking efforts for countries wary of government surveillance.

The project is an urgent effort by the British authorities to translate a surveillance tool deployed to fight China’s outbreak into something more palatable in Western democracies. The app is being developed for use in Britain, but could be adapted for other countries, particularly those with similarly centralized health systems, officials said.

The catch... Unlike the smartphone-tracking system used by the Chinese government, the British project would rely entirely on voluntary participation and would bank on people sharing information out of a sense of civic duty. more

Will Working from Home Increase Business Espionage Opportunities

I received a question today about inductive coupling; gleaning computer data leaked on to power lines (aka, mains) from keyboards, screens, etc. The person mentioned this was possible if the residences shared the same power transformer.

"So, does the increase in work-from-home offices these days increase the business espionage threat?"

Interesting question. Got me thinking.

I replied...
You're correct about sharing a transformer. Information can be induced onto the mains and intercepted on that side of the circuit. Several floors in an apartment building and usually 3-4 homes in a residential neighborhood can share one transformer.

But, let's think this through...
Back before we all became computerized the mains lines were relatively noise-free. Carrier-current bugs and wireless intercoms worked quite well for transmitting audio. These days, the noise level is a digital cacophony, created by everyone who shares the circuit.

The very low signal level a keyboard might contribute would be difficult to hear. Segregating the signal from other digital noise would also be a challenge. With diligence and the right instrumentation deciphering this digital data is doable. It would not be a nosy neighbor doing this. If you got that far, you're probably a government and the home worker has a bigger than average problem.

Realistically speaking...
A fairly static group of mains users also reduces risk. Your neighbors aren't deep cover spies who have waited years for the chance you might be forced to work from home. Moving into a neighborhood or apartment building with spying intentions is possible, but not easy to do on a moments notice. There are easier ways to obtain even more information, with a lot less work, and greater chance of success.

Worry about these things...
The weak links in a home office are: the computer, wireless keyboards, Wi-Fi, and internet modems. Current versions of wireless keyboards use Bluetooth (30 foot range) with some pretty good security features. As for date leaking onto the mains... Most smart people use a UPS battery backup with filtering for their computers, so no problem there. For anyone without a UPS getting one is a very worthwhile recommendation for multiple reasons.

Threats the average home office faces...

• shared cable internet, 
• Wi-Fi signal hacking, 
• spyware viruses (data, audio and video compromise), 
• Wi-Fi connected printer intercepts, 
• information phishing scams, 
• and none of the usual enterprise type protections. 

Attacks can be instituted by anybody, some staged from anywhere. Being on one side of a transformer isn't necessary. No need to tap the mains.

Imagine this...

• Step #1: The spy purchases a USB Rubber Ducky (to crack into the computer) and an o.mg cable (to crack into the smartphone). Total cost: <$200.00.
• Step #2: Spy plops these into an old Amazon box and mails it to "the mark."
• Step #3: Mark goes, "Wow, cool. I didn't order this. Amazon must have screwed up. Not worth sending back. I'll keep it."
• Step #4: Mark plugs this windfall into his computer and phone.
• Step #5: Gotcha! 

Think this isn't already happening? Think again. The USB Rubber Ducky is now on backorder.

Your company needs to have a technical security consultant on retainer—because there is more to know.

Face Masks v. Facial Recognition - China has it Covered

Hanwang, the facial-recognition company that has placed 2 million of its cameras at entrance gates across the world, started preparing for the coronavirus in early January.

Huang Lei, the company’s chief technical officer, said that even before the new virus was widely known about, he had begun to get requests...to update its software to recognize nurses wearing masks...

The company now says its masked facial recognition program has reached 95 percent accuracy in lab tests, and even claims that it is more accurate in real life, where its cameras take multiple photos of a person if the first attempt to identify them fails. more
