A cybersecurity researcher has raised privacy concerns about Samsung smart TVs after claiming to uncover extensive data-collection capabilities in the company’s Tizen operating system. The researcher, known online as log4j, said the investigation began after noticing unusually targeted advertisements on a Samsung TV purchased in 2025.
According to a report by Tom’s Hardware published on October 25, the researcher found code associated with viewing behaviour, screenshots, audio categorisation and advertising identifiers. These findings have not been independently verified on an unmodified television, so the claims should be treated with caution.
What Did the Researcher Claim to Find?
The researcher said they reverse-engineered the TV’s firmware and obtained root-level access to examine how the operating system handled user information.
The reported findings included telemetry related to network activity, viewing habits, advertisements skipped by users and video playback progress. The researcher also described computer-vision processing and a region-specific neural network that could analyse viewing behaviour.
Another concern involved audio collection. According to the report, the researcher found code that could look for connected devices with microphones, including soundbars or Bluetooth devices, even when the television itself did not have a microphone.
These are claims made by the researcher based on their examination of the device. They do not establish that every Samsung smart TV continuously records conversations or captures screenshots in ordinary use.
How Could This Data Be Used for Advertising?
Smart-TV manufacturers use several technologies to understand viewing behaviour and personalise advertising. Automatic content recognition, for example, can identify content displayed on a television, while advertising identifiers can help associate activity with a device or household.
The researcher alleged that Samsung’s TV software combined multiple forms of telemetry to support targeted advertising. If confirmed, the findings would raise questions about the scope of data collection, user consent and how information is shared with advertising partners.
However, the report does not independently establish how frequently the identified functions operate, what information is transmitted in practice or whether the data is collected in the manner alleged on standard retail devices.
A Second Researcher Tests Microphone Behaviour
The report also describes a test by a Hugging Face engineer known as ngxson, who examined microphone behaviour using a Flipper Zero device.
The engineer reported that the television opened a microphone for approximately five seconds before stopping. No further microphone activity was observed during the following hours.
There is an important limitation: the test television had already been rooted, and several settings had been disabled. The result therefore cannot establish how an unmodified Samsung TV behaves under normal conditions.
OpenAI Bans the Researcher’s Account
The controversy took another turn when log4j said OpenAI had banned their account for alleged cyber abuse. The researcher disputed the decision, saying the tools had been used for local reverse engineering rather than to exploit vulnerabilities.
The researcher suggested that an automated classification system may have triggered the ban. OpenAI’s reasoning was not independently established in the report.
The episode raises a broader question for cybersecurity research: how AI companies distinguish legitimate defensive investigation from activity that could enable harmful exploitation.
What Samsung TV Owners Should Know
The allegations do not prove that all Samsung televisions secretly record users. Nevertheless, smart-TV owners can take practical steps to reduce unnecessary data sharing:
- Review privacy, advertising and viewing-information settings.
- Disable automatic content recognition or personalised advertising features where available.
- Check microphone permissions and connected devices.
- Review the TV manufacturer’s privacy policy and software updates.
- Disconnect unused microphones or smart accessories.
The exact controls vary by model, region and software version.
Summary
A cybersecurity researcher known as log4j claims to have found extensive data-collection capabilities in a 2025 Samsung smart TV, including telemetry related to viewing behaviour, screenshots, audio and advertising identifiers. A separate microphone test produced limited observations on a modified television. The claims have not been independently verified on an unmodified device, and Samsung’s response was not included in the report.
