This is some serious revisionist history. GPT-2 wasn't instruction-following or even conversational.

it's a joke about the quality of samsung tv's rather than a serious comment - i should have said a perceptron could hack a samsung tv

Fair enough, sorry :)

My Philips smart tv started to give hints of programmed obsolescence this week, after 4 or 5 years. Besides the fact that I cannot install any real apps other than the ones built in this model (YouTube, Netflix and Prime). How I wish I could hack it and install another os. Honestly I don't think I have the time anymore to investigate this kind of thing. I decided to leave this comment here in hopes of someone pointing me in the right direction, if there's one. For now I'm thinking about getting a TV box and ditching the smart features all together.

The trick here was providing the firmware source code so it could see your vulnerabilities.

What would be the difficulty level for it to just read the machine code; are these models heavily relying on human language for clues?

Paired with Ghidra having a binary, being able to do a memory dump of a live running program, and being able to use wireshark to dump traffic over network/bluetooth/usb is VERY helpful if you don't have the source code.

You use decompilation tools and hope they left debug symbols in and it turns it into somewhat human-readable language which is often enough. Even when you don't binaries use libraries which are known or at some point hit documented interfaces so things can be reasoned about.

I had truly good “hacking” session with Codex. It’s not hacking, I wasn’t breaking anything, just jumping over the fences TP-Link put for me, owning the router, inside the network, knowing the admin password. But TP-Link really tried everything so you cannot access the router you own via API. They really tried to be smart with some very very broken and custom auth and encryption scheme. It took some half a day with C…

> It’s not hacking, I wasn’t breaking anything That's a very narrow read of the word "hacking". We're literally on a website called "Hacker News". We're not all trying to break things.

Definition 7 would be the relevant one here.

of all the benign technical possibilities this is actually pretty fun

I'm not sure I see "an AI can find insecure unknown bluetooth devices and compromise them" as entirely benign. I shiver to think how many such devices are probably in my house.

I'm not sure I'd use "compromise" at all - these (or the ones I have) are purposefully designed with zero authentication or pairing, the ones that use apps are already "compromised" in the sense that I can walk past any windowsill with one in it, open it, and it will immediately connect to it. I really don't mind if someone walking by were to change the LED color patterns

If I could turn a Samsung Smart TV into a dumb TV, or even just a basic monitor with input selection and basic volume control, I'd definitely take it.

Pretty much the same with my newly acquired LG Smart TV. I thought I might like webOS, since it's technically a descendent of palmOS, but oh no. No no no. I've opted just to not plug it in to the network and not provide a WiFi password.

My Samsung and LG TVs have never touched the LAN, nor will they. They have one job in life: being the HDMI display for our game consoles and Apple TVs. That's it. I'm sure they'd both like to serve me ads and report my viewing back to their servers, but they're living the life of dumb panels.

If it has an HDMI port, and even better if it has a USB port for power, is you can buy an $40 Amazon Fire Stick and use and upgrade with your TV until it physically dies.

Truly, no one should ever connect their "Smart" TV to the internet when better hardware and control is available to you in perpetuity via the HDMI port.

Not as cool as this, but I had a fun Claude Code experience when I asked it to look at my Bluetooth devices and do something "fun". It discovered a cheap set of RGB lights in my daughter's room (which I had no idea used Bluetooth for the remote - and not secured at all) and made them do a rainbow effect then documented the protocol so I could make my own remote control if needed.

I'm not even sure how cool this one is. It looks more like some experienced pentesters used Codex to vibe-code an exploit:

  In the course of driving Codex to the final destination, it definitely was about to go off-track if we did not steer it back immediately.

If I just point to the wall and say "nail" then I would day the hammer drive the nail

You didn't, you figured out where the nail needs to go, got the nail and then swung the hammer until the nail was driven. This is really just closer to a drill in that it automated the grunt work with full guidance.

Then explain vibe coders.

They are the customer who just tell their wishes, can't handle a hammer, can't handle a drill, don't know which nail, hammer or drill to use. Still the nail is in the wall.

Who did it?
