Amazon blunder leaks Alexa data to other customer

It appears that the fears of privacy and data protection advocates in regards to voice powered devices have come true; at least in a single case where Amazon leaked a customer's voice data to another customer.

What happened? According (PDF) to German computer magazine CT, one of Amazon's German customers requested access to the data the company had stored about him. Amazon sent the customer a zip archive with the data and the customer began to analyze it.

He noticed that the archive included about 1700 WAV files and a PDF document that contained Alexa transcripts. The customer did not own or use Alexa devices and concluded quickly, after playing some audio files, that the recordings were not his.

The customer contacted Amazon about the incident but nothing came out of it; he decided to contact CT and provided CT with a sample of the files. The audio recordings provided a great deal of information about the then-unknown Amazon customer including where and how Alexa was used, information about jobs, people, alarms, likes, home application controls, and transport inquiries.

CT created a profile of the user and was able to identify the customer, his girlfriend, and some friends, using it. CT contacted the customer and he confirmed that his voice was on the recordings.

Amazon told the magazine that the leak "was an unfortunate mishap that was the result of human error". Amazon did contact both customers after CT contacted the company.

Privacy issue

delete amazon alexa recordings

Amazon stores Alexa voice data indefinitely in the cloud. The company does so to "improve its services". The data may be used to identify owners of Alexa devices and others mentioned in recordings or audible when recordings take place. While it depends on how Alexa devices are used, it is clear that the recordings contain private information that most, if not all, customers would be very uncomfortable with if leaked to others.

Most owners of voice controlled devices are probably unaware, or indifferent, that their data is stored in the cloud indefinitely.

Amazon customers may delete voice recordings that Amazon has stored in the cloud on https://amazon.de/alexaprivacy/. I was not able to access the functionality on the main Amazon website, https://amazon.com/alexaprivacy/, as it redirected the request automatically.

The German page is accessible and provides options to delete recordings that Amazon has on file. There is no option, however, to block Amazon from storing recordings in the first place. It is unclear if the page works only for German customers or all Amazon customers.

Closing Words

Companies need to take human errors into account when it comes to privacy leaks and violations. The Amazon case demonstrates that leaks may happen for numerous reasons including successful hacking attempts, software error, or human error.

Now You: Do you use voice controlled devices?

    Martin, I would appreciate that you do not censor this post, as it’s informative writing.

    Onur, there is a misleading statement “[…] GIFs are animated images …”. No, obviously you don’t seem to have take much notice of what you were told back in March regarding; Graphics Interchange Format (GIF).

    For example, https://www.ghacks.net/2023/03/31/whats-gif-explanation-and-how-to-use-it/#comment-4562919 (if you had read my replies within that thread, you might have learnt something useful). I even mentioned, “GIF intrinsically supports animated images (GIF89a)”.

    You linked to said article, [Related: …] within this article, but have somehow failed to take onboard what support you were given by several more knowledgeable people.

    If you used AI to help write this article, it has failed miserably.

    Martin, [#comment-4569908] is only meant to be in: [https://www.ghacks.net/2023/07/09/how-to-send-gifs-on-iphone-two-different-ways/]. Whereas it appears duplicated in several recent random low-quality non relevant articles.

    Obviously it [#comment-4569908] was posted: 9 July 2023. Long before this thread even existed… your database is falling over. Those comments are supposed to have unique ID values. It shouldn’t be possible to duplicate the post ID, if the database had referential integrity.

    That’s called “appointing” businesses to do the state’s dirty work!!!!!

    But the article says itself that those appointed were not happy – implying they had not choice!!!!!!

    Note: I replaced the quoted URI scheme: https:// with “>>” and posted.

    The current ghacks.net is owned by “Softonic International S.A.” (sold by Martin in October 2019), and due to the fate of M&A, ghacks.net has changed in quality.

    Many Authors of bloggers and advertisers certified by Softonic have joined the site, and the site is full of articles aimed at advertising and clickbait.

    As it stands, except for articles by Martin Brinkmann, Mike Turcotte, and Ashwin, they are low quality, unhelpful, and even vicious. It is better not to read those articles.

    By the way, if you use an RSS reader, you can track exactly where your comments are (I’m an iPad user, so I use “Feedly Classic”, but for Windows I prefer the desktop app “RSS Guard”).

    We all live in digital surveillance glass houses under scrutiny of evil people because of people like Musk. It’s only fair that he takes his turn.

    “Operating systems will be required to let the user choose the browser, virtual assistant and search engine of their choice. Microsoft cannot force users to use Bing or Edge. Apple will have to open up its iOS operating system to allow third-party app stores, aka allow sideloading of apps. Google, on the other hand, will need to provide users with the ability to uninstall preloaded apps (bloatware) from Android devices. Online services will need to allow users to unsubscribe from their platform easily. Gatekeepers need to provide interoperability with third-parties that offer similar services.”

    Wonderful ! Let’s hope they’ll comply with that law more than they are doing with the GDPR.
