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!
Then next time do a less clickbait-y title: OpenCode had a leak of API keys for their service that is similar to OpenRouter; this does not affect most users.
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.
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.
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.
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?
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.
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.
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.
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
what’s interesting is that all those efforts that go into sandboxing through virtualization wouldn’t have helped here. But the solutions that proxy the api keys and hide them from agents might have worked as a defense in depth.
of course any sensible engineer that uninstalled this 6 months ago and used codex and claude code directly also avoided this, gg
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?
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.
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.
it’s funny how no one ever announces their critical vulns with “we have been hacked, you should uninstall our software and use something else”, at some point in the severity of the vuln that should be the conclusion, but no one ever says it

The title should say "OpenCode Console" not "OpenCode".
How did you determine that it has been "flagged by many"?
The post was visible when I am logged in. But when I opened the /newest page on incognito the post wasn't there.
It’s #14 on homepage when not logged in, same as when logged in.

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.

that's why virustotal was flagging it then

Awaiting for detailed breakdown of the incident. I am more interested in knowing , how can a distillation attack leak / expose credentials.

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.
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
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?
It triggers me when these companies think that users are fool. I would have appreciated them, if they have disclosed things more transparently.
"mass distillation campaign" there's no public evidence of this. I wonder what OpenCode/Anomaly has, would be an interesting postmortem.
Obviously they don't want to share details because it's ongoing
Yes

Was it opencode who bragged about their vibecoding tokenmaxxing attitude or I'm mixing them with someone else?
wtf was I getting many use OpenCode on OpenCode cloud emails last few days. Were they set up so that hackers can get more info?
So are people going to wake up and see their Anthropic, openAI, etc accounts drained?
Yes
4 days ago red flags were raised

It’s fascinating that tokens are so valuable that people are spending so much time and effort hacking to obtain API keys.
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.
The tokens of frontier are valuable...
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?)
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.
bots get caught and downvoting requires reputation.

> security breach
> related to a large scale distillation attack
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?
Yes, they think we are foooool
Looking forward to the post-mortem of this incident.
Yes, I am interested in how a distillation attack can leak credentials...
But isn’t OpenCode open source why does it need credentials.
For the inference APIs, which need to bill users. It's unclear why OpenCode's servers (presumably) had access to the API credentials.
Because people cut and pasted them in.
They function similar to openrouter BYOK.
Maybe they support cloud agents.
opencode go and zen?

Damn, that sucks. I didn't know OpenCode was this bad when it came to privacy.
If i dont use any of their models nor i am signed in, is that a problem? i dont see anything in wireshark except for models.opencode.ai
