First, Anker informed us it was unattainable. Then, it lined its tracks. It repeatedly deflected whereas totally ignoring our emails. So shortly earlier than Christmas, we gave the corporate an ultimatum: if Anker wouldn’t reply why its supposedly always-encrypted Eufy cameras had been producing unencrypted streams — amongst different questions — we’d publish a narrative concerning the firm’s lack of solutions.
It labored.
In a collection of emails to The Verge, Anker has lastly admitted its Eufy safety cameras are not natively end-to-end encrypted — they’ll and did produce unencrypted video streams for Eufy’s internet portal, like those we accessed from throughout the USA utilizing an unusual media participant.
However Anker says that’s now largely mounted. Each video stream request originating from Eufy’s internet portal will now be end-to-end encrypted — like they’re with Eufy’s app — and the corporate says it’s updating each single Eufy digicam to make use of WebRTC, which is encrypted by default. Studying between the strains, although, it appears that evidently these cameras may nonetheless produce unencrypted footage upon request.
That’s not all Anker is disclosing immediately. The corporate has apologized for the dearth of communication and promised to do higher, confirming it’s bringing in outdoors safety and penetration testing corporations to audit Eufy’s practices, is in talks with a “main and well-known safety skilled” to supply an impartial report, is promising to create an official bug bounty program, and can launch a microsite in February to clarify how its safety works in additional element.
These impartial audits and experiences could also be crucial for Eufy to regain belief due to how the corporate has dealt with the findings of safety researchers and journalists. It’s a bit exhausting to take the corporate at its phrase!
However we additionally assume Anker Eufy clients, safety researchers and journalists should learn and weigh these phrases, significantly after so little preliminary communication from the corporate.
That’s why we’re publishing Anker’s full responses beneath.

Enjoying Dwell Movies in Third-Occasion Media Gamers
At this time, there are two major methods to view stay streams of eufy Safety cameras. One is to make use of the eufy Safety App, and the opposite is to make use of our safe Net portal at eufy.com.
Beforehand, after logging into our safe Net portal at eufy.com, a registered person may enter debug mode, use the Net browser’s DevTool to find the stay stream, after which play or share that hyperlink with another person to play outdoors of our safe system. Nonetheless, that may have been the person’s option to share that hyperlink, and they’d have wanted to first log into the eufy Net portal to get this hyperlink.
At this time, based mostly on trade suggestions and out of an abundance of warning, the eufy Safety Net portal now prohibits customers from getting into debug mode, and the code has been hardened and obfuscated. As well as, the video stream content material is encrypted, which signifies that these video streams can now not be performed on third-party media gamers resembling VLC.
I ought to notice, nevertheless, that solely 0.1 p.c of our present day by day customers use the safe Net portal function at eufy.com. Most of our customers use the eufy Safety app to view stay streams. Both manner, the earlier design of our Net portal had some points, which have since been resolved.
Regarding the PR consultant who answered your query about utilizing VLC, they conflated the query. This was a recognized subject, simply replicated and had been reported by the media. Nonetheless, they thought you had been asking if individuals aside from the registered person may uncover hyperlinks on their very own after which view them by means of a third-party media participant like VLC. The dynamic naming conference of the video hyperlinks was additionally addressed within the media protection, so I can see how this may occasionally have confused them. But it surely was not the official reply from our product groups. The actual reply to this query has been addressed above.
Video Finish-to-Finish Encryption
At this time, all movies (stay and recorded) shared between the person’s gadget to the eufy Safety Net portal or the eufy Safety App make the most of end-to-end encryption, which is applied utilizing AES and RSA algorithms.
Moreover, when a person makes use of the eufy Safety App to entry movies from their units, the connection between the eufy Safety App and the person’s gadget is end-to-end encrypted by means of a safe P2P service.
Homebase3 and eufyCam3/3C units launched in October 2022 use WebRTC for end-to-end encrypted communication when utilizing the Net portal to entry stay streams in a browser. And we’re rolling out WebRTC to ALL eufy Safety units proper now.
I must also notice if a person selects to make use of eufy Safety’s optionally available cloud storage add-on, this operation is end-to-end encrypted. As well as, upkeep of our cloud server complies with the necessities of ISO27701 and ISO27001 requirements. We’re additionally audited by exterior third-party regulators yearly.
Client Privateness
When utilizing native storage, eufy Safety can’t entry our customers’ video recordings. All video knowledge is encrypted and saved on the gadget itself and might solely be accessed or shared by the person. Moreover, eufy Safety has no entry to the person’s biometric particulars resembling fingerprints or facial recognition knowledge created by the customers’ native units. All these processes are additionally performed and saved domestically.
Person Picture Added To The Cloud
Beforehand, we had one gadget, the Video Doorbell Twin, that despatched and saved a picture of the person to our safe cloud. There’s numerous hypothesis and misinformation on this, so let me clarify how this seemingly incongruent course of took place.
First, the aim of sending a person picture from the eufy App to our units is to offer the native facial recognition software program a baseline to run its algorithm. All facial recognition processes are and have at all times been performed domestically on the person’s gadget. Within the case of our Video Doorbell Twin, a replica of that set-up picture was saved utilizing end-to-end encryption on our safe cloud. The rationale for this, was in case the person determined to switch the Video Doorbell Twin or add a further Video Doorbell Twin to their eufy Safety system, the system would pull the prevailing picture from the cloud throughout setup, quite than making the person take a brand new picture.
Once more, this course of was not consistent with our “native” mission and has been eliminated. At this time, like all different units within the eufy Safety lineup, our Video Doorbell Twin depends on local-only storage of person pictures and video knowledge. Not the cloud.
It’s essential to notice, that no person or facial recognition knowledge has ever been included with the photographs that had been despatched to the cloud.
Particular solutions, additionally from Eric Villines, Anker’s world head of comms
Why do your supposedly end-to-end encrypted cameras produce unencrypted streams in any respect?
For the reason that very starting, eufy Safety was designed to permit customers to stream stay and recorded footage from their units to their eufy Safety cell app. These streams have at all times used end-to-end encryption. And that encryption has at all times been performed domestically both immediately on the digicam or on a eufy HomeBase gadget.
The eufy Net portal was created for customers to handle their account particulars and add optionally available providers resembling service plans and cloud storage. After receiving requests from some customers, the product group determined so as to add a stay view operate to the Net portal so customers may lengthen their safety monitoring to their desktops. The Net portal was designed to require the person to login, nevertheless it was not designed utilizing end-to-end encryption.
At this time, lower than 0.1 p.c of our energetic customers make the most of the stay streaming function on the Net portal; nevertheless, it is rather clear to all of us that encryption protocols ought to have been designed into this resolution from the very starting. This has been addressed, and immediately all of the stay streams from the person’s units to the Net portal now use end-to-end encryption.
Moreover, all units will now use WebRTC to deliver end-to-end encrypted communication when utilizing the Net portal to entry stay streams in a browser. That is already out there on our new HomeBase 3 and eufyCam 3 collection. We started rolling out firmware updates to all different units final week.
With the current points, there was numerous inside discussions on how our groups develop and launch new options. A number of new protocols and procedures have been put in place to make it possible for all knowledge flowing from the person’s units to the eufy Safety App or Net portal should make the most of end-to-end encryption.
If the cameras have at all times been encrypting footage domestically, as you say, how did they immediately have unencrypted footage to ship to your internet portal?
First, video triggered by the safety system’s regular processes (movement, somebody ringing the doorbell, and so on.), is at all times recorded, saved, and encrypted domestically.
Dwell video will not be recorded. Subsequently, the point-to-point encryption course of solely occurs when the eufy Safety system receives a request from the person to start stay streaming.
The P2P course of then begins, waking up the digicam, encoding the stay video in real-time utilizing a dynamic key, after which decoding that video on the opposite facet utilizing a dynamic key.
The eufy Safety app helps each stay and recorded video streaming and has at all times used P2P encryption. That is utilized by 99.9 p.c of our customers and is the first methodology to view stay and recorded movies.
However point-to-point encryption requires processes to be arrange on each ends, and the P2P processes and necessities are very totally different for the eufy gadget to the eufy Cell app than the eufy gadget to the eufy Net portal (browser),
That mentioned, the Net portal beforehand was not designed to assist P2P encryption for viewing stay streams. This was protected by means of a person login to the Net portal.
This wasn’t sufficient, and it’s been mounted.
Moreover, we’re additionally upgrading the Net portal stay encryption course of to WebRTC. That is presently being pushed to all units as an OTA firmware replace.
Is it true that “ZXSecurity17Cam@” is an precise encryption key? If not, why did that seem in your code labeled as an encryption key and seem in a GitHub repo from 2019?
No. All our video streams are encrypted with a dynamic key as an alternative of a hard and fast key. The “ZXSecurity17Cam@” was a setting parameter for creating and testing in a really outdated software program model, which was deserted years in the past. We’ve eliminated this code to alleviate any misunderstanding.
Past doubtlessly tapping into an unencrypted stream, are there some other issues that Eufy’s servers can remotely inform a digicam to do?
No. The one technique to handle native gadget options resembling locking and unlocking a door, turning on floodlights, and so on, is thru the person’s eufy Safety app.
Do Eufy cameras domestically and natively encrypt stay video as it’s recorded and streamed, or do they solely encrypt the following recordings / recordsdata?
When a person accesses a stay stream from one in every of their cameras, this video footage isn’t being recorded. It’s merely being stay streamed immediately from the person’s gadget to their eufy Safety App or to eufy’s safe Net portal. At this time, that is all performed utilizing end-to-end encryption.
Moreover, each eufy Safety digicam data, shops, and encrypts movies domestically – both immediately on the digicam or on a HomeBase gadget. This has at all times been the case since our first eufyCam was launched.
Which P2P service is used to end-to-end encrypt connections between the eufy app and a person’s gadget?
We use a patented, third-party P2P know-how, closely optimized for eufy Safety’s merchandise.
Do some other components of Eufy’s service depend on unencrypted streams, resembling Eufy’s desktop internet portal?
No. Outdoors of the current subject with the Net portal, which has been addressed, all our video streaming processes (each stay and recorded) are designed to make use of end-to-end encryption.
Are there any Eufy digicam fashions that do not transmit unencrypted streams?
I’m not positive I perceive this query. However as famous above ALL cameras when sending stay or recorded video feeds to both the eufy Safety app or eufy Net portal use end-to-end encryption.
Will Eufy utterly disable the transmission of unencrypted streams? When? If not, why not?
Answered above. Outdoors of the current subject with the Net portal, which has been addressed, all our video streaming processes (each stay and recorded) are designed to make use of end-to-end encryption.
Past the thumbnails and the unencrypted streams, are there some other non-public knowledge or figuring out components that Eufy’s cameras enable entry to by way of the cloud?
eufy Safety units don’t share movies, person pictures or biometric particulars (fingerprints, facial recognition particulars) with the cloud. All of that is processed, saved, and encrypted domestically on the person’s gadget.
There are a number of regular processes that require using the cloud resembling account setup, push notifications, preliminary gadget setup, gadget OTA, and so on. We can be launching a microsite quickly with infographics to raised clarify all our key processes – and that are performed domestically, and which require using the cloud.
Eufy says it can’t entry customers’ video recordings. What about livestreams from its cameras?
eufy Safety has no entry to the person’s stay streams or recorded movies.
Does Eufy share different info with legislation enforcement past recordings, resembling entry to a person’s account and / or their livestreams?
eufy doesn’t have entry to the person’s stay video streams or domestically saved movies. It could be as much as the person to share these particulars with legislation enforcement officers.
eufy Safety’s mission is to guard, not simply our buyer’s property, but in addition their privateness. And we consider one of the best ways to guard our clients ‘ privateness is to verify these particulars are saved of their possession and of their management.
Has Anker retained any impartial safety corporations to conduct an audit of its practices following these disclosures?
First, there have been no knowledge leaks, nor did we violate GDPR or different knowledge safety legal guidelines.
Nonetheless, safety is an ever-evolving area, and we need to be sure that we do all the things in our energy to guard our shoppers’ privateness. To that finish, we’re actively engaged on a number of totally different methods:
Along with what we have already got in place, we can be bringing on a number of new safety consulting, certification, and penetration testing corporations shortly to conduct a complete safety danger evaluation of our merchandise and get rid of potential dangers.
We’re additionally in discussions with a number one and well-known safety skilled in order that they’ll produce an impartial report about our present safety and privateness programs and practices.
We’re establishing a “eufy Safety bounty program” to create a greater and extra collaborative system for safety researchers to assist us uncover any vulnerabilities in our eufy Safety system.
We’ve formally engaged PWC and TrustARC to conduct a complete safety evaluation of our merchandise. That is thrilling, and we are going to present extra particulars on this once they turn out to be out there.
Lastly, initially of subsequent month, we are going to launch a microsite to raised clarify how our processes work, to supply clearer explanations on that are performed domestically, and which presently require using our safe cloud.
We promise to supply extra well timed updates in our group (and to the media!) to maintain shoppers higher knowledgeable on any updates to those methods.
Which safety consultants and specialists are signing on, assuming a few of these offers have been signed but?
We’re nonetheless in negotiations and can present these particulars very quickly.
When does Eufy intend to launch the bounty program?
We’re nonetheless in chats with a number of outdoors distributors and can present particulars quickly. This can be a main precedence for us as we need to create a extra formal course of to encourage trade suggestions and collaboration.
Will Anker offer refunds to these clients who purchased cameras based mostly on Eufy’s privateness dedication?
We deal with all our customer support in-house, and people groups are nicely educated to method each subject on a case-by-case foundation. Clearly, we are going to do no matter is in our energy to make issues proper and preserve our clients joyful.
To be clear, Anker / Eufy will not be apologizing for transmitting unencrypted streams?
In my view, I consider we’ve begun to acknowledge the problems and promised to do higher. Nonetheless, an apology ought to include extra particulars on what occurred and the corrective steps we’ve performed to verify this doesn’t occur once more.
Over the past a number of weeks, the group has been working to repair points, enhance our inside processes and convey in additional impartial oversight.
We can be issuing an replace to the our customers in early February, to debate lots of the issues we’ve touched on on this e-mail trade; present some updates on the opposite bigger scale initiatives we can be doing; and in addition launch our new micro-site to raised clarify which processes are performed domestically, and that are performed within the cloud.
At the moment, and with all this particulars laid out extra transparently, we are able to present a extra considerate apology. And an apology that’s higher backed up by an actual plan.
Along with these solutions, Anker claims that it didn’t deliberately delete these privateness guarantees from its web site:
Relating to our privateness coverage, whereas we had been working to re-write this a couple of weeks in the past and be clearer about which processes used the cloud and which didn’t, somebody jumped the gun and pushed a redacted model. I can guarantee you this wasn’t performed for any nefarious causes, however merely a collection of unlucky occasions that in the end compounded our complete communication processes.
Eufy truly up to date and strengthened that privateness dedication web page once more since our authentic story, although it nonetheless isn’t worded fairly as strongly as the unique model.
