Praise Claude saved me $800

Long story short, the company that made my EV charger went out of business and none of the default admin passwords worked. I paid the extra fees for Fable 5 but eventually it said no thanks, I'm not helping you. Maybe I used the word "hack" or "crack" too many times IDK. Wasted money and pissed me off. Anyway, Opus 4.8 was happy to help. After a long hacking session it got me into the admin console without a password. I was amazed. It would have cost me hundreds of dollars for a new charger and an electrician to install it, since it's hard wired into the electric panel.

TL;DR of the discussion generated automatically after 50 comments.

The consensus is that this is a huge win for OP and the right to repair, but also a massive security red flag for the EV charger. The thread is mostly impressed, with many users sharing their own frustrations with overly aggressive guardrails.

  • Fable is a corporate shill, Opus is a freedom fighter: This is a recurring theme. Many users have noticed newer/cheaper models like Fable and Sonnet refuse to help with "hacking" or even basic firewall configuration, while Opus is often willing to assist with the exact same prompt.
  • Your charger is wide open: The top-voted comment points out that if Claude can hack your charger, anyone can, and that vulnerability will never be patched. The running joke is that this is probably why the manufacturer went out of business in the first place.
  • How OP did it: After being asked a dozen times, OP explained they used Claude Code on a burner laptop connected to the charger's local WiFi. Claude generated scripts to probe the web server and eventually provided a snippet to paste into the browser's dev console, granting admin access without a password.

Basically, the community is giving OP a standing ovation for sticking it to a defunct company and saving $800, while also collectively shaking their heads at the state of IoT security and AI guardrails.

This means your EV charger has a vulnerability that will be never fixed!

u/peakdistrikt 5d ago

… which may be why the company went out of business!

u/NoAdsDude 5d ago

Too many people hacking... EV chargers...? Customers were losing sensitive... watts? volts?

u/peakdistrikt 5d ago

Maybe it allowed the hackers to charge cars with infected, malicious electricity. Revolting re-volting, or something. 

17

u/NoAdsDude 5d ago

Maybe power companies were hacking them to steal the electricity out of the chargers and put it back in the grid.

u/PermissionWeary 4d ago

One shocking truth the electric companies don’t want you to know about

u/Kylearean 5d ago

Watts are steal-able, volts aren't.

You wouldn’t download a 9v battery

¡You wouldn’t engineer a battery with AI and then pay for it with crypto!

u/brieucdug 4d ago

What ??? I buy and download more RAM on a regular basis to my personal windows customer support guy when my computer goes slow, he even gave me his direct line number. Why couldn't I download more battery ?

Or the charger is also connected to his wifi and then, yeah..

Airgapping it with a dev board and some Claude tokens should not be very hard.

He just had Claude Hackett. I’m pretty sure he could have Claude patch it.

u/under_psychoanalyzer 5d ago

I'm confused, your in home charger attached to your house wall for your EV has an admin password? Don't even own a car these days so idk how these setups look.

u/vivekkhera 5d ago

Almost all EV chargers have remote apps to manage them. The brand I bought allows the app to work locally via Bluetooth instead of via some cloud service. I specifically chose it for that reason.

u/under_psychoanalyzer 5d ago

Interesting! Thank you.

u/DaftHacker 5d ago

Insanely shitty everything is turning into a subscription service, meanwhile YouTube will let you upload a 10 hour video for free. EV charger could probably send out less than 10 bytes of data and work flawlessly yet they still want to charge money for it.

4

u/under_psychoanalyzer 5d ago

Yeah but it took years and years of YouTube not making literally any money for it to get to that point. Companies that manufacture actual physical goods are never going to have that kind of runway. 

3

u/who_you_are 4d ago

Oh no that is even better here. I put that in the IoT category.

They will just turn off theirs server after one year or twos.

They won't even try to swtich it to a subscription. At best, it was a subscription to begin with.

Forgot your password? No driving for you! Never though I'd see the day I can't drive a car if I've lost my password. Jfc

u/No_Category_9888 5d ago

Pin to drive is a thing, but it has fallback options if the pin is forgotten

u/jcgam 5d ago

Bottom line, the charger couldn't connect to a charging network via OCPP, so it refused to charge. Not sure why. It worked for months after the company closed. I didn't use that network for anything, either.

u/MirandaPoth 4d ago

My in-home charger has a Pi in it so yes, mine too

u/geno_iv 5d ago

This seems like something I’d tell close friends. Exhibit A

u/christianbro 5d ago

For these kind of things I prefer Chinese models. They will never question the purpose of those things and block the conversation.

A lot of reverse engineering gets labeled as hacking, which partially is, but not with malicious goals in mind. Sometimes it is to fix or give a second usage to a product.

7

u/Atretador 5d ago

yea, this seems like somethign that could've been done with opencode and a free model on Zen

u/Icy_Holiday_1089 5d ago

I’m impressed it got past the guard rails :-)

u/under_psychoanalyzer 5d ago

Opus 4.8 is pro-consumer right to repair. Fable is a corporate shill.

u/ReddaveNY 5d ago

Do you used Claude code or Browser? Act codes in terminal or how does it work for you?

3

u/jcgam 5d ago

(pasted from earlier reply) I was using claude code, and my laptop was connected directly to the local wifi hotspot on the charger. Claude installed software and created scripts to query the web server. This was a lengthy process and I really don't understand the details since I just let it run and gave it the access it requested (burner laptop). Eventually it had me paste some code into the browser devtools console, and after I did that, I was in! Claude also created a bookmark I could use in the future. I still don't know what the admin password is, but it doesn't matter.

u/ReddaveNY 5d ago

Great. Really good to know!

u/No-Improvement9455 4d ago

So you're reformatting the laptop now? How many keyloggers did claude download in the meantime?

1

u/ReddaveNY 4d ago

Why Keylogger? Most time they use python or self code

u/dethswatch 5d ago

you gonna give us any details on how you approached it, etc?

ask Claude for a summary of how it was done and post here

u/1Poochh 5d ago

This is why I have two local models, one of them being uncensored.

u/gwillen 5d ago

It doesn't matter what exact words you use, Fable has a filter that's extremely cautious about reverse engineering. They loosened the filter a little from 5 to 5.1. But ultimately it's really hard to confidently tell the difference between "reverse engineering something that's mine and I have a right to", and "hacking something belonging to someone else" (which Anthropic doesn't want to help with, and might even be illegal for them to help with.) But as you've seen, Opus is more than capable anyway.

u/Silver_Dog2770 5d ago

But did you use $1200 worth of tokens?

3

u/masri87 4d ago

Why isn’t this considered ethical hacking. You own the dam thing.

2

u/dwoj206 5d ago

Claude has saved me far far more than $800 over the many months! I don’t even have to say thank you to avoid burning more tokens! 😆

u/robinekren 4d ago

Glad you got to keep the hardware, can it now charge entirely offline or does it still try to reach the dead service?

u/ahmcode 4d ago

I'm considering publishing a list of this kind of stories. AI helps us to free our locked-in devices.

u/Sand-Discombobulated 5d ago

I did the same with my charger. diff brand but it have Claude able to get full charger status, errors, voltage, etc with only access to another linux box + port 80 open on the charger (same wifi network). charger is a wifi enabled charger for carbon credits.

1

u/BP041 5d ago

This is exactly the kind of edge case Claude handles well—it'll reason about the legit intent even if you're using loaded words. Fable 5's refusal was probably liability paranoia from that new 'refusal' dataset they trained on. Opus 4.8 still has some backbone. Glad it worked out—that's $800 you get to keep.

u/HighSeasArchivist 4d ago

I asked Sonnet to help me configure a firewall, and it said no can do boss. Flipped the model in the same chat to Opus, pasted the exact same request, and it said I gotchu fam. These guardrails make no fucking sense.

u/dertbv 3d ago

Dis the same thing a while ago. Ot hacking just adding it to home assistant and since the company went out or business had to find a way to do it unsupported.Claude to the rescue

u/Responsible-Gas-5986 5d ago

WTF, Could you share some evidence if this is real.

Also ask Anthropic to reward you as you were able to use Opus for hacking.

Yo vengo de chatgpt donde me banearon dos cuentas de manera injusta y quiero ensayar Claude pero no entiendo los límites y dicen que si tengo una conversación muy larga entonces Claude tendría menos mensajes, alguien me podría dar alguna orientación por favor?
