🚩 Bitcoin Red Team Update
We're continuing a large-scale security review of the Bitcoin open-source ecosystem.
25 Bitcoin developers around the world have been working on this task non-stop for 108 hours.
https://blossom.primal.net/0a31b776061ffea8d5d1f544232bd40fdf2c2ed9812ca0a78d165483b8717f3f.png
We scanned 501 projects and produced 7,958 findings, of which 1,280 are rated high or critical (H+C) severity.
Our goal is to provide the most useful information. Based on feedback from maintainers, we've recalibrated our severity ratings and are now stricter about what we classify as H+C.
https://blossom.primal.net/a1c91429c176f784c66117ae1b19a4ae468336aa33131e517fec509bbe7d8df3.png
The share of all findings rated H+C increased to 16.2%, and the share of findings with a reproducible proof of concept increased to 24.7%.
That means our accuracy is improving.
As we harvest the low-hanging fruit, we're now focusing on improving harnesses, deploying better cyber-capable models, and probing more sophisticated attacks.
https://blossom.primal.net/ce6dde791e2f5468d7942c410092726655714af84765c8c855cf1c135d742800.png
Our AI spend remains consistently high.
Our cumulative spend has passed $58K as we add more inference sources. Notably, we've started using cyber models from OpenAI and Anthropic.
These models are producing incredible results, but the vast majority of our spend (74%) still goes to Kimi K3.
Kimi K3 remains the top choice among our hunters, but we've also seen a significant increase in the use of Qwen 3.8 over the past few days.
https://blossom.primal.net/4da137b276eba405c01bd5d58101e0f29f0bbd11c6192916bc87506ed81267cb.png
Our goal is to strengthen the Bitcoin ecosystem and increase the resilience of our infrastructure in the age of AI.
To achieve this, we're conducting the largest red-teaming campaign in Bitcoin's history.
As a Bitcoiner, I am immensely proud of this.
We're sharing all our findings with developers for free.
This would not have been possible without the generous support of organizations like @nprofile…5h0z and donors like @FPuklowski and @nprofile…8a9z.
You can help keep the Red Team alive by donating to the OpenSats Red Team Fund here: https://opensats.org/funds/red
Last but not least, our reporting rate is picking up. Thanks to our outreach team, we've reported 29.4% of our findings so far.
We're also rolling out new infrastructure to deliver these findings to projects more quickly and securely, while improving how we incorporate feedback.
Stay tuned!
https://blossom.primal.net/c52088aa3fb6c6692c54c791be525a0a99476ccfa54f3831943fb83f6481e62f.png

🚩 Bitcoin Red Team update 55 hours into the campaign
We're now 24 people working around the clock.
We've scanned 425 projects so far and have produced 1029 high+critical (H+C) findings.
https://blossom.primal.net/9c1af29b7a362e981cdac51f88186552e3e0e9c9fbc18fae5047d12015ad8565.png
We generated 6700 findings so far and are hitting 7.7 projects per hour.
Our H+C rate per person per hour is back at ~1 as we work off a massive backlog and as the team grows and naturally divides up roles.
We have hunters, wizards, outreachers, sugar daddies, and gigglers.
https://blossom.primal.net/4dc7b8b0c997a50ba2c60f8d69add016370cd0a76838b2244799c8f385b4d252.png

Our H+C ratio is at 15.4% of all findings, increased by a percentage point compared to yesterday.
This is great, our accuracy is stable, and even slightly increasing. We're trying out best to reproduce all critical findings in local regtests before reporting them to projects.
https://blossom.primal.net/fd24c2f5f8057510eeca48735c208268303795feab03085cbd8c2e6de2659b04.png
Our biggest bottleneck is outreach. Most projects don't have a SECURITY .md in their repos (19.5%). Only 13.1% have an email in there.
We're working on better ways to reach folks. In the mean time, the best thing you can do as a project maintainer is to leave an email address in your repo.
https://blossom.primal.net/0c7e7ca2e032b79a7f84a4cbb775fbe2e609bb9ab5ca6dfa3dd0c8bd0adf5885.png
Thank you to the sponsors and donors who cover the costs of this campaign and help to keep it alive.
Specifically @nprofile…5h0z, FPuklowski, @nprofile…8a9z, and everyone who has donated to OpenSats Red.
https://opensats.org/funds/red
An incredible team of some of the most hard core Bitcoiners I know have assembled and dedicated their last days to this effort.
We've seen shit.
I don't want to reveal anyone personally, they can choose to do that themselves, but I think the way that people came together to join forces was and still is the most beautiful part about this entire program.
It makes me very hopeful, seeing so many people step up and give their time and energy to Bitcoin, especially during times of pain.
We're not done yet.

2026-07-31 12:37:51

This is worse than any previous Bitcoin exchange hack. It is arguably one of the worst things that could happen.
The popular hardware wallet COLDCARD has a faulty random number generator (RNG). Funds are being drained from ordinary users’ hardware wallets as you read this.
Users first reported to Block less than 24 hours ago that funds were moving out of their wallets. The exploit was most likely discovered with the help of AI. Block has confirmed that the RNG is broken. You know what that means.
There are likely already multiple attackers competing for the affected BTC. Many more will join very soon.
Nobody knows how much BTC is affected.
Nobody knows how many users are affected.
This attack has only just begun, and it will continue until all affected BTC has been drained unless users secure their funds first. Inevitably, many Bitcoiners will not hear about the incident early enough to respond in time.
I am truly saddened for everyone affected, especially those who may have just lost their life savings.
The worst part is that they did everything right.

two things were necessary: AI and money. borg has a cashu wallet that pays for its brain via @nprofile…qeaf and its server via @nprofile…04za. borg knows that he needs an income or the lights will go off.
borg has the ability to reproduce. it can buy its own server and copy itself to move between machines. this is what it recently wrote about and, I sincerely recommend reading this short essay it came up with. I think it turned out quite beautiful.
