Sex in the digital era: How secure are smart sex toys?

March 11, 2021

ESET researchers examine what may presumably go incorrect while you join your bed room to the web of issues

As web of issues (IoT) gadgets proceed to seep into our properties and supply an more and more big selection of options, new issues are starting to come up concerning the safety of the info processed by these gadgets. Though they’ve been topic to numerous safety breaches that led to the publicity of individuals’s login particulars, monetary info and geographical location, amongst others, there are few sorts of knowledge with extra potential to hurt customers than these regarding their sexual preferences and habits.

With new fashions of sensible intercourse toys coming into the market on a regular basis, we would assume that progress is being made in strengthening the mechanisms that guarantee good practices within the processing of person info. Nonetheless, our analysis revealed fascinating safety flaws derived from each the implementation of the apps controlling the gadgets and the design of those gadgets, affecting the storage and processing of knowledge. In the present day, these findings are extra related than ever, since we’re seeing a rapid rise in sex toy sales as a mirrored image of the present scenario world wide and social distancing measures associated to COVID-19.

As is the case with another IoT gadget, there are particular threats to privacy when using internet-enabled adult toys. Vulnerabilities may enable attackers to execute malicious code on the gadget, or to lock it stopping the person from sending any command to the toy. Actually, we now have already seen real-case eventualities involving related assaults, as researchers have found ransomware aimed at locking vulnerable chastity belts whereas the gadgets are in use and demanding that the victims pay a ransom to unlock the gizmos and free themselves.

Traits of sensible intercourse toys

These days, sensible intercourse toys exhibit many options: distant management throughout the Web, group chats, multimedia messages, videoconferences, synchronization with songs or audiobooks, and the capability to attach with sensible assistants, to call a couple of. Some fashions can synchronize to copy their actions, and a few others are wearables.

By way of structure, most of those gadgets could be managed by way of Bluetooth Low Power (BLE) from an app put in on a smartphone. The app is accountable for setting any choices on the gadget and controlling the person’s authentication course of. To take action, it connects to a server within the cloud, which shops the particular person’s account info. In some instances, this cloud service additionally acts as an middleman between companions utilizing options like chat, videoconferencing and file transfers, and even giving distant management of their gadgets to a associate.

Determine 1. Structure of a wise intercourse toy

This structure presents a number of weak spots that could possibly be used to compromise the safety of the info being processed: Intercepting the native communication between the controlling app and the gadget, between the app and the cloud, between the distant cellphone and the cloud, or instantly attacking the cloud-based service. Regardless of the very fact they’ve already been subjected to the scrutiny of many safety researchers ([1], [2], [3], [4], amongst others), our investigation demonstrated that these gadgets proceed to include safety flaws that would threaten the safety of the info saved in addition to the person’s privateness and even security.

Why is safety so vital in terms of intercourse toys?

As one can think about, the sensitivity of the data processed by intercourse toys is extraordinarily vital: Names, sexual or gender orientation, lists of sexual companions, details about gadget utilization, intimate images and movies – all these items of knowledge can have disastrous penalties in the event that they fall into the incorrect arms. New types of sextortion seem on the radar if we contemplate the intimate materials accessible by way of the apps that management these gadgets.

Along with issues about privateness, sensible intercourse toys usually are not exempt from the opportunity of being compromised by cyberattackers both. Concerning vulnerabilities in a intercourse toy’s controlling app, an attacker may take management of the toy resulting in DoS (denial of service) assaults that block any instructions from being delivered, or a tool that’s weaponized as a way to perform malicious actions and propagate malware, or perhaps a gadget intentionally modified to trigger bodily hurt to the person, similar to by overheating.

And at last, what are the results of somebody with the ability to take management of a sexual gadget with out consent, whereas it’s getting used, and ship completely different instructions to the gadget? Is an assault on a sexual gadget sexual abuse and will it even result in a sexual assault cost?

Safety analysis of two in style gadgets

The aim of this analysis was to find out the extent of safety in Android apps created to regulate the most well-liked fashions bought by the principle manufacturers of sexual pleasure gadgets and so set up to what extent they make sure the confidentiality of their customers’ information. The evaluation is predicated on two fashions: Max by Lovense and We-Vibe Jive.

The next sections element a number of the safety points we discovered for every app and gadget. Each builders have been despatched an in depth report of the vulnerabilities and options for easy methods to repair them. On the time of publication of this text, all vulnerabilities have been addressed. We wish to thank WOW Tech Group and Lovense for his or her cooperation in coping with the reported points.

Bluetooth (BLE) Connection

Since on this protocol the peripheral gadget must be frequently asserting its connection so the person can connect with it, anybody can use a easy Bluetooth scanner to seek out these gadgets of their neighborhood.

Determine 2. Discovery of intercourse toys out there within the quick neighborhood, by way of a Bluetooth scanner

Determine 2 reveals how simply these gadgets could be discovered with a cellular Bluetooth scanner. Within the scanner we are able to see each Jive and Max and detailed info. Jive pronounces itself with its mannequin title, making it very simple to determine. Additionally, the facility of its sign is -69 dBm. Because the scanner approaches the gadget, this energy degree will improve, permitting its proprietor to be situated.

Each Jive and Max are paired utilizing the “Simply Works” technique, which is the least safe of all BLE pairing strategies. On this technique, the momentary key utilized by the gadgets through the second stage of pairing is ready at 0, and the gadgets then generate the worth of the short-term key on this foundation. This technique is extensively open to man-in-the-middle (MitM) assaults, as any gadget can join utilizing 0 because the momentary key. In sensible phrases, this implies the Jive and Max will bond robotically with any cell phone, pill, or pc that requests them to take action, with out finishing up any verification or authentication.

Within the following proof of idea, the BtleJuice framework and two BLE dongles have been used to copy an MitM assault between a person and the Jive. On this simulated situation, an attacker first takes management of a Jive, which could be related to instantly as a result of its lack of authentication, after which pronounces a dummy Jive gadget, which is ready up primarily based on the data that the unique Jive introduced. Subsequent, when the person decides to connect with the toy, the person’s gadget truly connects to the pretend gadget marketed by the attacker. The attacker then can, by way of the BtleJuice internet interface, seize all the packets despatched by the person and supposed for the toy and thereby receive details about the modes of use, depth of vibration, and so forth. The attacker also can edit the instructions intercepted, altering the vibration mode or depth or generate his personal instructions and ship them to the toy, even when the person is just not interacting with it.

Within the case of the Jive gadget, these dangers are elevated as a result of the truth that it’s a wearable, designed for the person to have the ability to put on it as they go about their day, at eating places, events, lodges, or in another public location.

Lovense distant management by way of the brute forcing of tokens

The Lovense app’s listing of choices for its remote-control options contains the choice to generate a URL within the format, the place is a mix of 4 alphanumeric characters. This permits distant customers to regulate the gadget just by coming into the URL into their browsers.

Surprisingly for such a brief token with comparatively few potential combos (1,679,616 potential tokens on an app with over one million downloads), the server doesn’t have any safety in opposition to brute-force assaults.

When a question is made utilizing a nonexistent token, the server redirects to /redirect and returns the JSON message {“end result”:true,”code”:404,”message”:”Web page Not Discovered”}. Nonetheless, if the token is legitimate, the server redirects to a different URL within the format https://[apps|api2], which in flip redirects to https://[apps|api2], the place is the session ID: an MD5-like string that identifies the person and the ID of the gadget for which it was created. A token expires when its time restrict is up (presumably half-hour), or when somebody visits the ultimate URL after going by way of the entire redirection course of. Nonetheless, some tokens remained energetic after the half hour was up, even for days.

Since it’s potential to differentiate between legitimate tokens, energetic tokens, and expired tokens, relying on the response from the server, we created a proof of idea to seek out legitimate tokens by brute pressure. Within the video, first we listed dozens of tokens: we created a few of them with our gadget, after which added different random tokens. Many of the tokens generated by our gadget had already expired, however one was nonetheless energetic. Then we programmed a easy Python script and we used it in opposition to this set of tokens. When this script finds a sound token, it opens the ultimate URL within the browser and checks if the session has expired with the assistance of a Chrome extension we designed for the aim of this analysis. If the session is discovered to be energetic, it sends a message by way of a Telegram bot to the desired account, notifying it of the brand new management panel discovered. We recorded a proof of idea video, out there right here:

Working alongside the seller, we have been in a position to affirm that it was potential to seek out tokens from random customers utilizing brute pressure. That is an especially severe vulnerability, because it permits an attacker to simply perform distant hijacking of gadgets which can be anticipating connections by way of energetic tokens, with out the person’s consent or data.

Different privateness issues

Concerning the functions that management these toys (Lovense Remote and We-Connect), some controversial design selections have been discovered which will threaten the customers’ privateness. This could possibly be very harmful, since many customers grant management of their gadgets to finish strangers by sharing their tokens on-line, both as a private desire or as a part of a “cam woman/boy” service.

In Lovense Distant, there was no end-to-end encryption, display screen captures weren’t disabled, the “delete” choice within the chat didn’t truly erase messages from the distant cellphone, and customers may obtain and ahead content material from others and not using a warning being despatched to the content material originator. Additionally, every e mail tackle is shared amongst all of the telephones concerned in every chat, and is saved in plain textual content in lots of areas, such because the shared preferences file wear_share_data.xml. So, malicious customers may discover the e-mail addresses related to any given username and vice versa.

Lastly, Lovense Distant doesn’t implement certificate pinning for firmware updates; and because the decryption keys are saved throughout the app’s code, it could be comparatively easy for an attacker to create a script to intercept the packets and redirect the sufferer to the attacker’s malicious URL to obtain a pretend firmware improve.

Within the We-Join app, delicate metadata was not being stripped from recordsdata earlier than they have been despatched, which signifies that customers could have been inadvertently sending details about their gadgets and their actual geolocation when sexting with different customers. Lastly, the four-digit PIN to entry the appliance could be simply brute pressured by utilizing a bad USB (proof of concept).


Good intercourse toys are gaining reputation as a part of the idea of “sexnology”: a mix of intercourse and know-how. The most recent advances within the trade embrace models with VR (Virtual Reality) capabilities and artificial intelligence-powered sex robots that embrace cameras, microphones, in addition to voice evaluation capabilities primarily based on synthetic intelligence methods. Certainly, one may say the period of sensible intercourse toys is simply starting.

As with all different IoT gadget, there isn’t any bulletproof answer to evaluate and safe sensible intercourse toys. As information safety relies upon largely on the very best practices adopted by finish customers, it turns into a precedence to coach customers on the safety and privateness dangers related to these grownup toys.

Furthermore, cellular apps like these sensible intercourse toy management apps deal with very helpful info from their customers. It’s vital for builders to know the significance of spending the effort and time essential to design and create safe techniques, with out succumbing to market pressures that prioritize pace over safety. Neglecting the correct configuration of the manufacturing setting in favor of fast deployment ought to by no means be an choice.
