Grote's Bertholdia Moth: when bats are detected nearby, these moths emit a rapid series of ultrasonic clicks that act as a "jammer," interfering with the bat's sonar signals so that the moth can avoid detection

The Grote's bertholdia moth (B. trigona) is capable of emitting about 4,500 ultrasonic "clicks" per second. While there are other types of moths that use ultrasonic signals (in various ways) to avoid being preyed upon by bats, none of them have a more rapid-fire pace than this species.

The barrage of signals provides the moth with a way to remain hidden, because it interferes with the echolocation that bats use to navigate and locate prey.

As this article from Smithsonian explains:

... when approached by the bats, the moths produced their own ultrasonic clicking sounds at a rate of 4,500 times per second, blanketing the surrounding environment and cloaking themselves from sonar detection.

This article also expands upon the use of ultrasonic signals among moths:

Like other nocturnal insects, moths need to contend with bats. Unlike grasshoppers or beetles, they have soft bodies without spines or hard cuticles to protect them. Yet bats’ reliance on echolocation has given moths a way to avoid ending up as food: by tapping into their predators’ acoustic signals. Many have evolved ears that can hear the calls of bats. Some moths make ultrasonic squeaks, chirps, or clicks to warn their predators (honestly or not) that they are poisonous. Others generate near-constant, ultrasonic buzzes capable of jamming bat sonar.

Wearable Microphone Jamming

We engineered a wearable microphone jammer that is capable of disabling microphones in its user’s surroundings, including hidden microphones. Our device is based on a recent exploit that leverages the fact that when exposed to ultrasonic noise, commodity microphones will leak the noise into the audible range. Moreover, our device exploits a synergy between ultrasonic jamming and the naturally occurring movements that users induce on their wearable devices (e.g., bracelets) as they gesture or walk. We demonstrate that these movements can blur jamming blind spots and increase jamming coverage. Lastly, our wearable bracelet is built in a ring-layout that allows it to jam in multiple directions. This is beneficial in that it allows our jammer to protect against microphones hidden out of sight.

I saw a lot of people in the notes having the same concern as me, and nobody with any answers, so I did a little bit of research. I didn't search very extensively, but I only found one (1) article that addressed the question, so if you really care, then I'd recommend searching a bit more.

That said, here's what I found about this device in terms of whether it would impact people with hearing aids.

_

"What’s the problem in jamming?

Do we thought how will this research impact our surroundings?

Let’s say somebody is wearing this device in a public space then what will happen to the callers in surrounding area?

"During a phone interview, Mr. Lopes turned on the bracelet, resulting in static-like white noise for the listener on the other end." — nytimes

Do we thought what will happen to people attached with accessibility devices, say, cochlear implants, hearing aids etc.?

Yes, a lot of confused hearing aid users. The wearable jammer will hinder the devices which are critical for them to properly function.

Any other concerns?

Likely, the device will confuse the dogs, most likely hinder bats as they use echolocation of their prey and many other animals. Maybe, the only positive thing will be the less likeliness of rodents to nest near us.

So we should not go around shouting “What could go wrong with blasting out ultrasonic noise in every direction (Besides a lot of confused dogs…)”

It would be a loss if due to a critical need to protect privacy we end up inadvertently harming a group of people that are already at a disadvantage. For me that trade-off is not worth it.

Simply put, using this device publicly is insanely irresponsible and inconsiderate."

Ive been doing my own research on the matter, and found a number of interesting things.

First off: a research paper done by the Institute of System Security in Braunschweig, Germany reveals startling findings in their studies of ultrasonic Cross-device tracking:

“By analyzing prominent examples of commercial tracking technologies, we gained in- sights about their current state of the art and the underlying communication concepts. The case of SilverPush emphasizes that the step between spying and legitimately tracking is rather small. SilverPush and Lisnr share essential similarities in their communication protocol and signal processing. While the user is aware about Lisnr’s location tracking, SilverPush does not reveal the application names with the tracking functionality.”

“Throughout our empirical study, we confirm that audio beacons can be embedded in sound, such that mobile devices spot them with high accuracy while humans do not perceive the ultrasonic signals consciously. Moreover, we spot ultrasonic beacons from Lisnr in music and Shopkick beacons in 4 of 35 stores in two European cities. While we do not find indication of ultrasonic tracking in TV media, the receiver side looks more alarming in this case. At the time of writing, we are aware of 223 Silverpush Android applications that are listening in the background for inaudible beacons in TV without the user’s knowledge. Several among them have millions of downloads or are part of reputable companies, such as McDonald’s and Krispy Kreme.”

“Our findings strengthen our concerns that the deployment of ultrasonic tracking in-creases in the wild and therefore needs serious attention regarding its privacy consequences.”

(Emphasis Mine.)

Until as recently as august 2021, Google used these audio beacons. They have removed that capability for android devices. It is currently unclear wether IOS devices are still using them. Nevermind, they’re likely still used by apple, according to the “trusted” brands section on the silverpush site.

Additional sources:

github repository where google is storing the example code for the API.

Example project repository, which contains a startling number of projects related to advertising.

My fear is that somewhere out there is code that would allow someone to perform malicious attacks on user’s devices, similar to the “surfing attack” demonstrated during February of 2020

There is a silver lining, however. After a bit more digging, I found several projects dedicated to investigating this technology and preventing them from working.

Hackers steal data from Air-Gapped PCs with microphones & speakers

A research team from Israel’s Ben-Gurion University of the Negev ‘s cyber security research center has discovered a new way of data extraction from air-gapped computers via using passive devices like earphones, headphones, and speakers.

Now, the same research center has claimed to be able to use computer speakers and headphones to act as microphones and receive data. The devices can be used to send back the signals and make the otherwise safe practice of air-gapping less secure.

As per the new technique by information security training professionals, data is extracted in the form of inaudible ultrasonic sound waves and transmission occurs between two computers installed in the same room while data is shared without using microphones.

The research team created a custom protocol to carry out data transmission between two computers. One of them would be air-gapped while the other is connected to the internet and used to further relay the data. Through the attack, researchers claim to carry out speaker-to-headphone, headphone-to-headphone, and speaker-to-speaker data exfiltration.

Findings of this research were published by ArXiv on Friday in an academic paper titled “MOSQUITO: Covert Ultrasonic Transmissions between Two Air-Gapped Computers using Speaker-to-Speaker Communication.” Information security training analysts explained that their research shows how speakers can secretly be used to carry out data transmission between unconnected computers located within a distance of 9 meters.

The reason why they used speakers is that these can be considered microphones working in reverse order; speakers convert electronic signals into acoustic signals whereas microphones convert acoustic signals into electric. The conversion is assisted by a diaphragm in each of these devices, which can be used to reverse the process. This process of reversing the mechanism of a device like a speaker is called jack retasking.

A majority of new audio chipsets can be used for jack retasking because these offer an option of altering the audio port function through software. Malware can be used to reconfigure a speaker or headphone so that it acts like a microphone given that the device is unpowered and passive. The paper reads:

“The fact that loudspeakers, headphones and earphones are physically built like microphones, coupled with the fact that an audio port’s role in the PC can be altered programmatically, changing it from output to input, creates a vulnerability which can be abused by attackers.”

In the MOSQUITO attack, the information security training researchers used infected an air-gapped computer and could also be used to modulate or transform locally stored documents into audio signals. These signals could easily be relayed to another computer using headphones, earbuds or speakers.

The receiving computer would also be infected with malware and will convert connected speakers or headphones using jack retasking technique to make them serve as a microphone. The catch is that most of the PCs now have passive speakers while these have active, powered headphones, earbuds, and speakers.

Researchers could achieve data transmission successfully at the rate of 166 bit/sec using frequencies ranging between 18 to 24 kHz. There was just 1% error rate when data was transmitted to a 1kb binary file within the distance of 3meters. If the distance is increased to up to 9 meters, a 10 bit/sec transmission rate was achieved with the same error rate.

Authors also provided various mitigation techniques but admitted that all had their limitations. These techniques included designing speakers and headphones equipped with onboard amplifiers to prevent their use as a microphone.

Alternately, an ultrasonic jammer can be used and ultrasonic transmissions can be scanned. The software can be developed for preventing jack retasking and using UEFI/BIOS to fully disable audio hardware. Although there is another more practical solution for disconnecting the headphones or speakers it is not a very feasible method. While information security training analysts believes that monitoring ultrasonic band is a much more practical and reliable solution but when applied, it is bound to raise false alarms.
