Samsung Pulls Apps That Turn Smart TVs Into Proxy Nodes

The Discovery

A simple Pac-Man game promoted in Samsung's "Editor's Choice" section carried hidden functionality that could enlist the television running it into a network designed to route strangers' web traffic through ordinary households. Security researchers at Norwegian firm Mnemonic uncovered the residential proxy code while examining popular apps in Samsung's smart TV ecosystem, some claiming hundreds of millions of installs according to their developers.

The finding highlights a structural weakness in how app marketplaces vet software for connected devices. Many of the flagged applications consist of minimal code that primarily loads external content from remote servers. When Samsung's review process examines these submissions, it sees only the wrapper, a handful of lines that establish the app's basic framework. The actual functionality, delivered dynamically from elsewhere, remains largely invisible during vetting.

How Residential Proxies Work

Residential proxy networks, often shortened to "resproxies," function by commandeering ordinary internet connections and offering them as tunnels for third-party traffic. When proxy code activates on a device, that device becomes what network engineers call an exit node. Anyone paying for access to the proxy service can route their web requests through it, making their activity appear to originate from a residential address rather than a data center or suspicious location.

The appeal is straightforward. Websites and online services treat traffic from home IP addresses differently than traffic from commercial hosting providers. Rate limits relax. Anti-bot systems stand down. Geolocation restrictions become trivial to bypass. For companies scraping large volumes of public data or training AI models on web content, resproxies offer a way to distribute requests across thousands of endpoints simultaneously.

At DailyTechWire, we've tracked the growth of these networks across Asia-Pacific markets, where rising smart device penetration has created vast pools of potential exit nodes. The technology itself carries no inherent criminality, but its opacity and the ease with which it can be embedded in consumer software have made it attractive to actors with less benign intentions. Cybersecurity teams report difficulty distinguishing legitimate traffic routed through residential proxies from reconnaissance activity, credential stuffing attacks, and data exfiltration by state-sponsored groups.

Inside the Code

Harrison Sand, an offensive security consultant at Mnemonic, gained root access to a Samsung television's operating system to analyze network flows in detail. By intercepting and logging all traffic entering and leaving the device, he could observe which applications were opening connections beyond their advertised purpose.

The Pac-Man game contained software from Bright Data, an Israel-based proxy provider that operates a global network of residential endpoints. Sand noted that the proxy functionality remained dormant until the user encountered and accepted a consent prompt. Once activated, the code continued running in the background even after the game was closed, turning the television into a persistent relay for external traffic.

During his monitoring period, Sand observed network activity suggesting large-scale scraping of LinkedIn profiles and collection of training data for machine learning models. He emphasized that his vantage point captured only a fraction of the total traffic flowing through Bright Data's infrastructure. The encrypted nature of most proxy traffic meant that detailed inspection of payloads was impossible without breaking encryption, which would itself constitute a legal and technical challenge.

Sand also raised a more troubling scenario. Because these apps load their active code from remote servers, a single change on the provider's backend could instantly modify the behavior of every installed instance. Hundreds of millions of televisions could theoretically be converted into a coordinated botnet with no action required from users and no new app update passing through Samsung's review pipeline.

Samsung's Response

Samsung confirmed it would implement platform-wide policies explicitly prohibiting residential proxy SDKs. The company stated it has already restricted new app registrations that incorporate such functionality and is working to identify and remove existing apps containing these components from its store.

The move mirrors action taken by LG last month, which announced its own ban after reporting found that roughly 42 percent of apps in its smart TV marketplace enlisted devices into proxy networks. The convergence of policy responses suggests the issue extends beyond any single manufacturer and reflects broader challenges in governing software ecosystems for consumer electronics.

The timing of Samsung's intervention is significant. Smart TVs have become ubiquitous in both developed and emerging markets across Asia, with shipments in Southeast Asia alone reaching tens of millions of units annually. Each television represents not just a screen but a networked computer running a full operating system, capable of executing arbitrary code and maintaining persistent internet connections. As these devices proliferate in homes and offices, the potential attack surface and the value of enlisting them into distributed networks both increase.

The Broader Implications

The residential proxy issue exposes tensions inherent in modern app distribution models. Platforms benefit from large app catalogs that drive hardware sales and user engagement. Developers, including those with limited resources or questionable intent, can publish software with minimal friction. Users gain access to a wide variety of content and services. But the review processes designed to protect users struggle to keep pace with the volume of submissions and the sophistication of techniques used to obscure problematic functionality.

Dynamic content loading, the method used by many of the flagged Samsung apps, is not inherently malicious. Legitimate developers use it to update content without requiring users to download new app versions. News apps pull fresh articles, streaming services refresh catalogs, and games load new levels all through this mechanism. But the same architecture allows a developer to pass a benign version through review and later push different code to installed instances.

This creates an asymmetry. App store operators must decide whether to ban entire classes of functionality that have both legitimate and illegitimate uses, or to invest in runtime monitoring systems that can detect when apps behave differently in production than they did during review. The former risks stifling innovation and limiting developer flexibility. The latter demands continuous infrastructure investment and raises privacy concerns about monitoring user devices.

For end users, the proxy issue underscores the difficulty of making informed consent decisions. A prompt asking permission to "share your internet connection" may appear alongside dozens of other permission requests that users have learned to click through reflexively. The consequences, including potential legal liability if proxy traffic is used for illegal activity, remain abstract until something goes wrong.

Cybersecurity professionals in the region have noted that residential proxies complicate attribution during incident response. When an intrusion appears to originate from a residential IP address in suburban Singapore or a small business in Taipei, investigators must determine whether the source is a compromised endpoint, a proxy node, or an actual threat actor operating from that location. Each possibility demands a different response, and the investigation itself consumes time during which attackers may be deepening their access or exfiltrating data.

What Comes Next

Samsung's policy shift will test whether manufacturer-level controls can effectively address proxy proliferation. The company must now scan its existing app inventory, identify which applications contain proxy SDKs, and remove them without disrupting legitimate services. Developers whose apps are pulled will need to either remove the offending code or accept exclusion from the platform.

Enforcement will be the harder challenge. Determined developers can obfuscate code to evade automated scanning, or they can wait until the initial cleanup concludes before attempting to reintroduce proxy functionality through new apps or updates. Without runtime monitoring that detects actual proxy behavior rather than just the presence of known SDKs, the policy becomes a deterrent rather than a technical barrier.

The issue also raises questions about other consumer electronics categories. Android-based streaming boxes, digital photo frames, and even some routers ship with pre-installed software that may include proxy functionality. These devices often receive less scrutiny than smartphones or computers, yet they maintain always-on internet connections and sit inside network perimeters. If smart TV apps can enlist millions of devices into proxy networks, similar code could be running on countless other gadgets.

Regulatory attention may follow. Policymakers in several Asian markets have begun examining data practices in consumer electronics, driven by privacy concerns and growing awareness of supply chain security risks. Residential proxies occupy an uncomfortable middle ground: not quite malware, but not entirely benign either, especially when users are unaware their devices are participating.

The technical community will be watching how Samsung's ban affects Bright Data and similar providers. If major platforms exclude proxy SDKs, these companies will need to find alternative distribution channels or business models. Some may pivot toward enterprise offerings that enlist corporate devices with explicit IT approval. Others may seek partnerships with internet service providers to build proxy networks at the infrastructure level rather than the endpoint level.

For now, the immediate impact is clear. Millions of Samsung smart TVs will lose apps they may have installed for simple entertainment, and the invisible background activity routing strangers' web traffic through living rooms will cease. Whether that change proves durable will depend on enforcement rigor, developer behavior, and the willingness of other manufacturers to adopt similar policies. The cat-and-mouse dynamic between platform operators and those seeking to monetize consumer devices is far from over.
