If you've ever wondered why smart TVs are so cheap, this is why.

@log4j rooted his Samsung and found an always-on hot mic, automatic content recognition, geolocation, network mapping, ad targeting and user profiling, shared with Samsung's "400 partners".

A lot of it can be blocked in <15 min, wrote a basic guide below.

What your TV is doing

The main culprit is ACR (automatic content recognition). Your TV screenshots what's on screen, fingerprints it, and sends it home to build your ad profile. Samsung does it every 500ms, LG every 10ms [1].

What is insane: it happens on connected devices too.
Plug in your laptop, your console, your work machine, and your TV can fingerprint that via HDMI [1].
He also found that if your Samsung doesn't have a mic, it'll look for one from a connected soundbar or bluetooth device.

It's on by default, and you likely agreed to it on the setup screen you clicked through in 10 seconds.

Step 1: Turn off ACR

Samsung: Terms & Privacy → Viewing Information Services
LG: Live Plus
Vizio: Viewing Data
Roku: "Use info from TV inputs"
Sony/Google TV: Samba Interactive TV

Menus vary by model, but those are the names to look for. While you're in there, opt out of interest-based ads, reset your advertising ID, decline every optional privacy agreement, turn off voice recognition, and delete apps you never open.

Step 2: Give smart devices their own network

Put the TV, cameras, speakers and vacuum on your router's guest/IoT network. The logic is simple: these devices rarely get patched. If one gets compromised (getting drastically more frequent with AI), it shouldn't be able to see your other devices or home network.

Step 3: Block trackers for the whole house with DNS-level filtering

NextDNS (cloud-based) is easy and has a solid free plan. Pi-hole is a little bit more work if you prefer self hosting. For simplicity we'll focus on the former.

1. Sign up at https://t.co/IwhafVWVM8 (free tier is plenty)
2. Privacy tab: add a blocklist (OISD is a good bet) and turn on Native Tracking Protection for Samsung, LG, Roku, Amazon (see attached image)
3. Setup tab: copy your endpoint
4. Paste it into your router's DNS settings as DNS-over-HTTPS/TLS (or use the IPs + "Link IP" if your router only does plain DNS)
5. Bonus: block outbound port 53 except to your router. Some devices hardcode their own DNS to get around you

Then open the NextDNS logs and watch how often your TV phones home. It's eye-opening. If an app or update breaks, find the domain in the logs and allowlist it.

Why they do this

TV prices are down 97% since 2000 [2]. Most of that is better manufacturing and brutal competition. But once margins on the hardware hit zero, the cost moved to you.

In Q3 2024, Vizio lost $6.7M selling TVs and made $115.8M in gross profit from ads and viewing data [3]. They've said on earnings calls that they keep TV prices low to grow the audience they sell to advertisers. Walmart bought them in 2024.

This isn't a conspiracy theory either. Vizio paid $2.2M to the FTC in 2017 for tracking 11 million TVs without consent. Last December, Texas sued Samsung, LG, Sony, Hisense and TCL over ACR. Samsung and LG have since agreed to stop collecting that data without explicit consent [4].

TL;DR
1. ACR off
2. Ads + voice off
3. Smart devices on their own network
4. NextDNS filtering on the router

‼️ BREAKING: Oracle Issues Emergency Java Update for Critical 9.1 HTTPS Trust Vulnerability

Details: https://t.co/XZV8KY0rPW

Oracle has released an emergency Java security update to address CVE-2026-91403, a critical vulnerability affecting how Java applications trust digital certificates. Published on October 21, 2026, the alert assigns the flaw a CVSS 3.1 score of 9.1 and covers Oracle Java SE and GraalVM.

The update blocks affected intermediate certificate authority certificates linked to eMudhra. According to Oracle’s security advisory, the issue affects the Java Secure Socket Extension, or JSSE, component.

Oracle rates exploitation as low complexity, with no authentication or user interaction required. Successful attacks can expose or change sensitive data, although the risk matrix lists no availability impact.

Being different will be your only advantage in the future. Like it always has been, but even more so.

People use AI more and more, but not the right way. They delegate their thinking and imagination to their AI. The result looks great. But all results look the same.

And by doing so they lose their originality and imagination.

Quick illustration I just added in the @CyberiadLabs course: "pick a random number between 1 and 10".

In 2024, YouGov asked this question to 2,241 adults in Great Britain. A third said 7, but every number from 1 to 10 got some answers. In 2025, Springboards, a company that sells its own AI model, asked GPT-4o 100 times. It said 7 in 92 of them, and never said 1, 2, 5, 8, 9 or 10.

We ran the same test today with Claude Opus 5.5, from Anthropic: we asked it the same question 100 times, each time in a new chat with nothing else in it, through Claude Code, Anthropic's tool for programmers. It was even worse: it said 7 all 100 times.

This illustrates perfectly and simply the fact that AI will only push you to uniformity and if you use it blindly you will sound like everyone else, losing any advantage and losing your imagination in the process.

Because picking a number is one thing. But now do it for everything:

- write my pitch
- name my startup
- draft my strategy
- write my LinkedIn post
- write my essay
- …

and you’ll end up with the same pitch, name, strategy, post and essay as everyone else.

Stay different. Use AI to superpower you, not replace you.
