On Monday, Democratic presidential nominee Kamala Harris was photographed utilizing wired headphones related to a cellphone as she boarded Air Pressure Two.
This isn’t the primary time Harris has been photographed utilizing wired headphones. In her well-known “We did it, Joe” name to President Joe Biden about their 2020 victory over Donald Trump, Harris is seen holding a pair of wired headphones in a single hand. Actually, she has accomplished a number of tv interviews and official movies carrying wired headphones.
In 2021, Politico provided some perception into Harris’ headphones desire, reporting that she “has lengthy felt that Bluetooth headphones are a safety threat” and “insists on utilizing wired headphones” consequently, in keeping with three nameless former marketing campaign aides. (HuffPost reached out to Harris’ workplace about her wired headphone use however has not obtained a response.)
Now, we’d not know precisely why Harris depends on wired headphones. But when it’s due to safety dangers, she is true to be distrustful of Bluetooth units, in keeping with cybersecurity specialists.
Why Bluetooth headphones have safety dangers.
Bluetooth transmits information via the air inside a sure vary, which makes it inherently weak to close by threats, stated safety architect and licensed moral hacker Maril Vernon. She stated it was “clever” of Harris to make use of wired headphones.
″[Harris’] bodily connection is much more safe as a result of it eliminates the danger of the wi-fi sign being intercepted, and there’s just about no alternative for an attacker to snoop on her dialog if she’s utilizing the system and the headphones, except they had been standing proper subsequent to her they usually may bodily hear via her headphones, or they compromised her cellular system,” Vernon stated.
If Harris did use Bluetooth headphones, there could be extra threat for somebody with the ability to pay attention to her calls via a hacked connection, Kevin Johnson, CEO of the consultancy Safe Concepts and a hacker employed by firms to check their very own safety vulnerabilities, defined.
“In case you are elected to be the vice chairman of the US, then sure … cease utilizing Bluetooth totally,” he stated.
Only a few of us will probably be entrusted with state secrets and techniques that we have to hold personal, however you’re prone to be one of many estimated billions who use a Bluetooth-enabled system. So do you have to comply with Harris’ lead and persist with wired headphones?
The excellent news is that except you’re a presidential nominee who’s a high-profile goal for hackers, you’re OK to maintain utilizing your wi-fi headphones — so long as you are taking some cautionary steps.
The way to be safer when utilizing Bluetooth headphones and different units.
Each of the cybersecurity specialists that talked with HuffPost use Bluetooth-enabled headphones of their on a regular basis lives. However in addition they comply with a couple of safety protocols to make their listening expertise safer in public areas. Right here’s how:
1. Don’t depart your Bluetooth on 24 hours a day.
Break your behavior of leaving your Bluetooth setting on on a regular basis. Because the Federal Communications Fee warns on its web site, “Preserving it energetic permits hackers to find what different units you related to earlier than, spoof a type of units, and acquire entry to your system.”
Switching off your Bluetooth if you’re not actively utilizing it should “reduce the window of alternative for attackers to try to hook up with or intrude along with your connection to your units,” Vernon stated.
For instance, she recommended turning off your Bluetooth setting if you take breaks from listening to your audiobook or music.
Additionally, take heed to the variety of strangers round you if you toggle again in your Bluetooth setting. Make sure that “you’re very near the system you need to hook up with, and also you’re not round different folks,” Vernon suggested, noting that the extra distance you have got from different folks, the safer you’re when connecting.
When attainable, join your cellphone to your Bluetooth headphones within the privateness of your property earlier than you allow versus public settings like an airport or on board a airplane, she added.
2. Do common checks of what units are paired to your Bluetooth connection.
Bluetooth-enabled units can hook up with your cellphone or automotive in a course of often called “pairing.” However too many people neglect to “unpair” our units after we’re accomplished utilizing Bluetooth. And that’s a giant safety threat.
“So many individuals hook up with their buddy’s automotive one time to play music and by no means, ever go and take away their buddy’s automotive [from their list of paired devices],” Vernon stated. Now that your cellular system and your buddy’s automotive are related, they will grow to be reconnected “at any time for those who get near that system.”
Certain, it’s high-quality if it’s your buddy, however worrisome if it’s somebody you don’t belief.
“Any Bluetooth system has the potential of sharing information that you simply don’t notice it has,” Johnson stated. “So you must take into consideration all of the units that you simply join and use.”
Take the instance of renting a automotive and utilizing your cellphone’s Bluetooth capabilities to hearken to music or make hands-free calls. Don’t neglect to unpair your cellphone and “configure every thing to neglect that system” from the rented automotive after you come it, Johnson suggested. If you happen to don’t clear this information, somebody can acquire entry to your cellphone contacts and conversations in worst-case eventualities.
3. Use fashionable Bluetooth variations and do software program updates.
Bluetooth has gone via a number of iterations previously 10 years. Most fashionable headphones, like second-generation AirPods, use Bluetooth 5.0 or newer. However it is best to test what the supported Bluetooth model is in your units by wanting up the specs on your system. Johnson stated for those who purchased Bluetooth-enabled headphones within the final 5 or 6 years, you’re seemingly utilizing fashionable Bluetooth.
“Just be sure you’re not utilizing one thing you got off of Amazon that’s utilizing Bluetooth model three, which isn’t as encrypted as Bluetooth model 5,” Vernon stated.
Moreover, don’t ignore firmware updates for the cellphone you pair your wi-fi headphones with. These software program replace requests out of your system producer aren’t despatched to harass you, with Vernon explaining that “normally what they’re attempting to remove is distant code execution and folks connecting to your system with out your permission.”
4. Make it somewhat tougher for folks to guess which system is yours.
Are your AirPods, iPhone and iPad all at the moment recognized by your actual identify? If that’s the case, it is best to rethink this, Vernon stated. When your Bluetooth setting is on, your units are discoverable, they usually can reveal private particulars like your identify or your kids’s names that you’d reasonably strangers in your proximity not know.

Vernon really helpful naming your system “one thing bizarre, so nobody can correlate it to you,” and famous that it doubles as “an added layer of safety.”
She gave the instance of giving your Bluetooth-enabled system a random identify that isn’t yours, in order that manner hackers have “much less data to work with.”
Bluetooth has made it handy for us to remain related to our music, associates and a lot extra whereas we’re on the go, and except you have got a job that has extremely delicate data, you don’t have to surrender that ease of comfort altogether.
