A researcher can describe it as critical in text
But CVE scoring has a real methodology with various frameworks and takes time to do properly, just have a look at the NIST CVSS calculator
https://nvd.nist.gov/vuln-metrics/cvss/v3-calculator
A valid critical 9+ cve score is more science than propaganda
can it be that some of the redteam's critical vulnerabilities found are actually 7 or 8 cve? yes possible, but those are sill valid vulns to patch

agreed, but if provides at least some actionable remediation to even a 1/10th of the vulns it 'discovers' it still worth the cost
once dust settle a $/critical cve patched price will be distilled from redteam work, I think it is money well spent... albeit a bit rushed considering the epic fail of coinkite CTO

2026-08-06 20:41:55 CEST

- reply

$ spent is also the metric is useful when comparing to security audits and bug bounty programs (sadly already a low bar)
overstated or exagerating the impact of bugs are a thing for sure, it is still a useful tool to use can be useful as a starting point. But requires a human to verify vulns and give it a real cve rating
Third point is absolutely right, but you can train the modela and give the harness the right tooling to do the job of a team of junior vulnerability researchers

short answer is yes
nothing is broken on a hardware level, so as long as you safetly import a seed generated with enough entropy then it is not vulnerable
generating new seeds using the flawed firmware is what caused the current chaos
There is a new firmware that has been released, but people have been reporting it can brick your device. I would recommend moving your sats to a self custody software wallet first, then once the dust settles consider importing that seed into the coldcard with new firmware (if that is what you want to do)

not concerns currently, only thing to consider is passphrase length and complexity
Should be noted that your sparrow wallet backup should be encrypted with a long passphrase as well, since sparrow is not a hardware wallet there are still malware related risks.

see the DAO hack on Ethereum, also other projects it happens since patching allows bad actors to know what is vulnerable

ah... if a multsig is made up of only or majority seeds from the vulnerable coldcard. yes that makes sense to me
I am hearing of RBFs when a vulnerable wallet sends a multisig tx, when it is first seen in the mempool. from what i understand that only affects the cc wallets in the multisig... but if like you said they were all generated with the same cc then the whole multisig could be at risk of automated RBF

OpenSats is not some massive corporation with a 24/7 workforce

At this time there is still active firefighting to understand and have plebs secure their sats
shouting at a nonprofit org that has no association with this mess except they have one person who is on the board is really not a productive use of time and energy Beave

Why is #entropy important in #cryptography ?
check this webpage: https://keys.lol
Very simple example of why you need 'pure' randomness to generate entropy...
"How does this work?
A private key is basically just a number between 1 and 2256. This website generates keys for all of those numbers, spread out over pages of 128 keys each.
This website doesn't actually have a database of all private keys, that would take an impossible amount of disk space. Instead, keys are procedurally generated on the fly when a page is opened. The page number is used to calculate which keys should be on that page.
Finding an active wallet is hard, but not impossible. Every time you open a random page, you have a chance of finding someone else's fortune."

what gzuuus is saying is you can still use bitcoin, one bad firmware bug does not change how all the wallets operate
tbh you can still safely use any Coldcard out there, if you provide your own entropy... the wallet design / chip layout / software stack has not been compromised.... just the entropy of those who used the internals to make a new wallet (which is the majority of plebs who bought the wallet probably did)
want to use a paper wallet and never send a satoshi again? cool, you do you but that does not make your setup more / less secure if you trust some other software to generate entropy for you James
