I am the author of this post. Looks like OpenCode fans / team is not happy with this post coming on the first page of HN. It has already been flagged by many. I never ask for upvotes, but would be great if you can upvote it. Thanks!

How did you determine that it has been "flagged by many"?

The title should say "OpenCode Console" not "OpenCode".

Wait, is the openchode hack the cause of all the people complaining about their OAI usage getting drained/vanishing at alarming rates? That's pretty funny ngl.

The way some of this place's employees post and act online, can't say I feel all that bad.

I think every API key system should have endpoint "invalidate_api_key" this way whitehat hackers or the party who stored them could invalidate all keys in the case they leak. Now it is race against the time, and everybody got email, and everyone must act themselves.

It actually is a thing, although indirectly in a hacky way! If you push keys from GitHub secret scanning partners to a public repo or a gist, they get sent to the partner who (usually) instantly revoke them. So if you want to help someone, just make a public gist with the key and delete it like 15 seconds later, it'll be enough.

https://docs.github.com/en/code-security/reference/secret-se... has a table with the active partners

Only responsible thing in this case would have been for OpenCode people to invalidate all keys. But I guess it is not that straightforward if Anthropic/OpenAI etc don't have endpoint for it.

There's no self-serve endpoint, but OpenCode could send the inference providers the leaked keys and ask for them to be revoked, which is a thing the inference providers can do. It's possible that this'll happen, apparently remediation is still in progress.

It sounds like only a hosted service was compromised, not the open source OpenCode binary that users run on their own machines. So this wouldn't explain that.

Is my understanding correct that this only affected some OpenCode Zen users who stored their (BYOK) API keys from Anthropic/Google/OpenAI?

In essence they used OpenCode Zen similar to OpenRouter, where you can BYOK or use theirs and be charged token rates.

That's the only known impact so far. But we don't know the details of how these keys were exposed, so it's not entirely clear why or how "only keys" might have been affected

Why are my API keys in the workspace exposed? Does OpenCode send my API keys to their backend servers??? Was this a supply chain attack that infected the opencode program itself? What is going on?
reply
ameliaquining 20 minutes ago
If you use the hosted OpenCode Console and bring your own API keys, then they'd have your keys on their backend servers.

They need to explain this, by releasing a detailed RCA.

I’m a bit confused by the wording here, does it mean the credentials were hacked and then used to perform a mass distillation campaign?
reply

It triggers me when these companies think that users are fool. I would have appreciated them, if they have disclosed things more transparently.

Obviously they don't want to share details because it's ongoing

"mass distillation campaign" there's no public evidence of this. I wonder what OpenCode/Anomaly has, would be an interesting postmortem.

Was it opencode who bragged about their vibecoding tokenmaxxing attitude or I'm mixing them with someone else?

I don't use OpenCode but I would like to know who this impacts. Surely people who are just using OpenCode locally with their own credentials wouldn't be impacted, right? This sounds like something where you have a hosted service and you put your keys into that. Not saying this isn't bad, but it isn't clear and they're not sharing any information.

This appears to affect users of Opencode Console, which appears to be an Openrouter-type thing?

https://dev.opencode.ai/console/

It's actually kinda hard to figure out what it is. But it does appear to be different that the CLI

From https://opencode.ai/v2/docs#connect :

> If you’d like easy access to all the best coding models you can try out OpenCode Console.

Turns out even if you used credentials locally, you could've have been impacted as the .env files were also consumed by the agents. This is from some comments on Reddit / Google, so take it with a grain of salt.

So are people going to wake up and see their Anthropic, openAI, etc accounts drained?

It’s fascinating that tokens are so valuable that people are spending so much time and effort hacking to obtain API keys.
reply

They might have spent next to 0 time actually 'hacking' - they may have just told Opencode to hack Opencode website and let it run for hours or days till it succeeded.

Why are the comments pointing out there were warning signs early on being downvoted/flagged?

I looked at the linked comments, and they seem valid. I mean I dont want to go full tinfoil hat here, but what's the deal? Some people just really like opencode or something?

I think it may just be bad automated flagging. I vouch'd them since they don't really seem to violate any rules/guidelines (right?)
reply

Indeed. I've seen it happen before and it appears that they have automatic downvoting based on some criteria, possibly just some classifier. I've attributed it to some bot attack before, but it's a bit too common now.

Why does it being common downplay the bot attack to you? As time goes on, I'd assume bots activity to increase. I do not see it ever going away.
reply

bots get caught and downvoting requires reputation.

I'm not sure how this adds up. I could understand if this impacted their uptime, but not security.

Are they actually saying a bunch of credentials were stolen and are being used for distillation?

But isn’t OpenCode open source why does it need credentials.
reply

For the inference APIs, which need to bill users. It's unclear why OpenCode's servers (presumably) had access to the API credentials.

They function similar to openrouter BYOK.

From OpenCode Team

---

Hi, We identified unauthorized access to a legacy system that we were in the process of decommissioning. Third party provider keys (eg OpenAI, Anthropic) saved in your workspace may have been exposed. Please revoke and replace those keys through the relevant provider’s dashboard, update any applications using them, and review recent usage for unexpected activity.

We’re sorry this happened and will follow up with any updates.
