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!
They presumably meant that it’s been downranked relative to what you’d expect from a post with that many upvotes in that short of a time frame. Hundreds of upvotes in a few hours is usually a top 5 post
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.
It's a little more than that. It seems that keys for OpenAI / Anthropic APIs that were STORED on OpenCode's OpenRouter-like backend got leaked – which additionally means that OpenCode has no ability to refund people for their losses.
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.
Not any more than any other public endpoint service exposes.
This revocation endpoint can be protected by auth too. Use API key that you're revoking in auth.
I see now from another comment you thought about denial of service for service that leaked key. And I thought about mass leak resulting in DDOS onto API provider. Wrong guess from me.
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?
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 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.
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.
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 saw the email this morning from OpenCode about my key being compromised alongside an email from Anthropic stating that I used up my $20 in API credits for the month. I hope they built something cool with those tokens!
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.
you login to their website, and you are presented with a list of providers where you can click and add your provider api key.
how the key is stored on the backend isn't clear, but it is akin to handing your password or if you know crypto, your private key, to someone and letting them store it for you.
from what i can tell, there are no links within the console to a ToS, Privacy policy or anything else. there are no warnings or documentation about how they store your keys.
someone else in this thread linked to this issue, but this comment is especially insane given that i can't find any privacy policy or tos for the console.
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.
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
What the the purpose of this comment? Neither of those "red flags" you linked to are related (one is about config loading precedence, and the other is about Codex CLI, which is completely a completely different product and development team.
Exterior-compliance proxies, yes, are a good thing; but are also completely unrelated to the fact that OpenCode's hosted solution, that requires having credentials in some fashion, was popped.
Shitting on anyone who uses OpenCode (rather than your preferred vendor-specific product) as not being "sensible" is also completely out of hand and unnecessary.
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
> Beware of the author of tweet, who happens to be author of OpenCode - OpenCode will leak all your data to themselves and to shady 3rd parties. Author feigned ignorance and never fixed the issue. OpenCode among other harnesses is the shadiest of all.

I did have an account but moved off for security reasons.
This is one of the reasons I don't trust opencode. It looked very nice on paper when it first came out and there were no alternatives. However, today I'd probably stick with simple pi setup (not sure how much better than opencode, but it looks like they don't have all this cloud stuff) or just use one of the big tech agents and call it a day.

Oh they’re a YC company: https://www.ycombinator.com/companies/opencode
The title should say "OpenCode Console" not "OpenCode".
How did you determine that it has been "flagged by many"?
It's clearly heavily down voted, just look at when it was added, how many points it has and its relative position.
You cant downvote HN posts (comments you can)

That just turns a credential leak into a denial of service - one that can be triggered from anywhere.
In this case you'd probably prefer your key to be disabled rather than spending $$$ on tokens for everyone else
Think that through - the person who stole the key has the decision to use it or revoke it through this hypothetical system.
If they are acting maliciously, they will take the choice that most hurts you and/or benefits them.
If the key is useless to them and revoking it hurts you, then they would do that.
If the key wasn’t useless to them, then… they would just use it and not revoke it?
Not any more than any other public endpoint service exposes. This revocation endpoint can be protected by auth too. Use API key that you're revoking in auth.
How does that make any sense?
I see now from another comment you thought about denial of service for service that leaked key. And I thought about mass leak resulting in DDOS onto API provider. Wrong guess from me.
Yes. Is this a bad thing?
Of course it is? A key for some weather API getting leaked isn’t the end of the world, but having it revoked and breaking your weather app is.
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?
If you use the hosted OpenCode Console and bring your own API keys, then they'd have your keys on their backend servers.
The announcement is needlessly confusing, but if you only use the CLI, you're not affected. There is no supply chain attack.
They need to explain this, by releasing a detailed RCA.
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 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.
https://news.ycombinator.com/item?id=50108261
that's why virustotal was flagging it then
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.
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’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
[dead]
@dang this title needs updating: "OpenCode Console hacked: User credentials leaked"
The opencode CLI has no impact.
It doesn't say the CLI was hacked does it?
OpenCode = OpenCode CLI to most people (as seen in the dozens of comments making that assumption in this thread)
So are people going to wake up and see their Anthropic, openAI, etc accounts drained?
I saw the email this morning from OpenCode about my key being compromised alongside an email from Anthropic stating that I used up my $20 in API credits for the month. I hope they built something cool with those tokens!
Yes
They have shown so so so many times that their culture is not aligned with trustworthy software. Yet people keep using it.
It's not like there wouldn't be any other harnesses either. Just switch to literally anything else please.
Can you elaborate on that?
Was it opencode who bragged about their vibecoding tokenmaxxing attitude or I'm mixing them with someone else?
Honestly, who isn't bragging about their vibecoding tokenmaxxing attitude nowadays?
Awaiting for detailed breakdown of the incident. I am more interested in knowing , how can a distillation attack leak / expose credentials.
It’s fascinating that tokens are so valuable that people are spending so much time and effort hacking to obtain API keys.
API keys have been routinely stolen in mass automated attacks for malicious usage long before LLMs even existed
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...
> 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
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?

the ux is kind of crazy.

https://github.com/anomalyco/opencode/issues/10416#issuecomm...
FWIW, OpenRouter has the exact same feature.
and their TOS/Privacy policies are equally light on details.
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?
Looking forward to the post-mortem of this incident.
Yes, I am interested in how a distillation attack can leak credentials...
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?
All the comments I've seen about warning signs point to opencode the cli, where this is about one of opencode's hosted services.
Because they're unrelated to this incident.
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.
