Introduction
Samsung has begun banning smart TV applications that contain software capable of sharing users’ internet connections with third parties.
The move follows new security research from Norwegian cybersecurity company Mnemonic, which discovered residential proxy software inside several Samsung Smart TV applications.
The research raises concerns because some of these applications reportedly had very large installation numbers, while at least one was a simple Pac-Man game that had been prominently featured in Samsung’s Editor’s Choice section.
The issue involves residential proxy networks, which can route another person’s internet traffic through a consumer’s home or office connection.
Samsung said it has already restricted new app registrations containing such proxy functionality and is working to identify and remove existing applications containing the software.
Samsung Bans Risky Smart TV Apps
The issue centers on Samsung Smart TV Apps that contain residential proxy software.
Samsung said it has already restricted new app registrations that incorporate proxy functionality. The company is also implementing platform-wide developer policies that explicitly prohibit residential proxy SDKs.
Samsung is working to identify applications already available in its store and remove those containing prohibited components.
The company’s Smart TV platform provides users with access to a broad range of entertainment, gaming, lifestyle, and other applications. Samsung’s official support information also allows users to install, delete, lock, and automatically update apps.
How Samsung Smart TV Apps Can Share Internet Connections
The security problem comes from the way some modern applications are built.
Some Samsung Smart TV Apps are lightweight applications that load their main content from external websites or servers. This approach can make applications smaller and easier to develop.
However, researchers say this structure can also create challenges for security reviews.
An application may initially appear to contain only a small amount of code while additional functionality is loaded from another source.
Mnemonic security researcher Harrison Sand reportedly examined the network traffic generated by a Samsung smart TV after gaining deeper access to the device’s software.
The research found that certain applications could contain code associated with residential proxy networks.
When activated, this type of software can allow a device’s internet connection to become an exit point through which external users route their own web traffic.
That means the television is not simply receiving internet data for the owner. It could potentially also be passing traffic from outside parties through the same household connection.
What Are Residential Proxy Networks?
A residential proxy network routes internet traffic through devices connected to ordinary residential internet connections.
For example, instead of a website seeing traffic originating from a commercial data center, the traffic may appear to come from an ordinary household internet connection.
Residential proxies are not automatically illegal.
They can have legitimate uses, including market research, location testing, data collection, and accessing online information from different regions.
However, cybersecurity experts have also raised concerns about their misuse.
When residential proxy software is installed on consumer devices without users fully understanding what it does, those devices can potentially become part of a much larger network.
This is why Samsung Smart TV Apps containing residential proxy functionality have attracted attention from security researchers.

Why the Apps Create Security Risks
The presence of residential proxy software can create several potential risks for consumers.
1. Unknown Internet Traffic
A user’s connection could potentially carry traffic generated by someone else.
2. Privacy Concerns
Consumers may not realize that an application has functionality capable of using their network connection for external traffic.
3. IP Address Reputation
If someone uses a residential proxy connection for suspicious activity, the traffic may appear to originate from the household’s IP address.
4. Bandwidth Consumption
Additional network traffic could consume bandwidth and potentially affect internet performance.
5. Difficult Investigation
Residential proxy traffic can make it harder for cybersecurity investigators to determine where malicious activity actually originated.
For these reasons, consumers should pay attention to the permissions and consent screens shown by Samsung Smart TV Apps, particularly when an application asks to use network-related functionality.
Pac-Man Game Found With Proxy Software
One of the most unusual findings involved a Pac-Man game available for Samsung smart TVs.
According to the research, the application contained residential proxy software associated with Bright Data, a company that operates residential proxy networks.
The discovery was notable because the game was reportedly promoted in Samsung’s Editor’s Choice section.
The presence of proxy code did not necessarily mean that every user who installed the game automatically turned their TV into a proxy node.
According to the research, the functionality could remain dormant until a user accepted a consent screen.
After consent, the proxy software could run in the background until the application was removed.
This means the issue was not simply about downloading a game. It also involved understanding what users were agreeing to when accepting the application’s terms or consent request.
Samsung’s Response
Samsung has responded by taking action against applications that use residential proxy functionality.
The company said it has already restricted new app registrations that include these capabilities.
It is also introducing stricter developer policies that explicitly prohibit residential proxy SDKs across its Smart TV platform.
Samsung said it is working to identify and remove existing applications that contain the prohibited components.
The response highlights a growing challenge for companies operating connected-device app stores.
Samsung’s platform hosts a large variety of applications, from streaming services and games to lifestyle and information tools.
Why Residential Proxies Concern Cybersecurity Experts
Residential proxies have legitimate applications, but their misuse can create serious cybersecurity challenges.
Cybercriminals may use residential proxy networks to make malicious online activity appear to originate from ordinary household connections.
This can make it more difficult to identify the actual source of cyberattacks, scraping operations, or other suspicious activity.
The situation becomes more complicated when the traffic is encrypted because network observers may not be able to easily determine what information is being transferred.
The research into Samsung Smart TV Apps therefore highlights a wider concern beyond Samsung itself.
Smart TVs, streaming boxes, smartphones, and other connected devices can potentially become part of larger networks when applications contain third-party software development kits.
Could Millions of TVs Be Affected?
The scale of the issue has attracted attention because some app developers reportedly claimed extremely large installation figures.
However, an application’s claimed installation number does not necessarily mean that every television became an active proxy node.
In the Pac-Man case, the research indicated that users needed to accept a consent screen before the proxy functionality became active.
Nevertheless, the possibility of a large number of connected devices being used as network exit nodes highlights the importance of app-store security.
Samsung Smart TV Apps are installed on devices that are continuously connected to home networks, which makes careful security screening especially important.
What Samsung TV Users Should Do
Samsung TV owners can take several simple precautions.
Keep Your TV Updated
Install official software updates whenever they become available.
Review Your Installed Apps
Regularly check your TV’s application list and remove apps you no longer use.
Samsung provides options for installing, deleting, locking, and updating applications through its Smart TV interface.
Read Consent Screens
Don’t automatically accept every permission or consent request. Pay particular attention to anything involving network access or sharing.
Use Official Apps
Only install applications from the official Samsung app store.
Check for Unusual Network Activity
If your home internet suddenly becomes slower or data usage increases unexpectedly, check connected devices and installed applications.
Follow Samsung Security Updates
Keep an eye on official Samsung announcements for information about app removals and security changes.
