Why is Coinkite not warning users of how bad this catastrophe is getting?

> MPORTANT UPDATE: We just had our first confirmed loss of a Mk3 + 2 Word Passphrase.

I believe 2-of-3 multisig wallets are also at risk if the seed phrases were all generated on a ColdCard without using dice rolls for custom entropy and if none of the seed phrases also used a passphrase.

Due to ColdCard's borked code, the pool of possible seed phrases generated by ColdCard devices is predictable. One has to assume thieves are churning through combinations in order to find multisig wallets.

2-of-3 wallets should be considered to be at risk.

This warning should not have to come from some dude with a wacky username. Coinkite's handling of this catastrophe is inexcusable.

**EDITED TO ADD:**

[Youtube video with AnchorWatch CEO Rob Hamilton](https://youtu.be/rounYenvkU4?si=H3iwS8PyhYO3s15q&t=1671) and others. I'm watching it as I type this. He mentioned the multisig attacks and I'm now realizing the situation is even worse than I thought.

Someone needs to put funds in broken mk3 wallets with different level of passphrase entropy to see how this progresses.

    Excerpt only. The complete copy is held offline and backs quotations on this site. The original publication remains the canonical public source.

How to check this yourself

The excerpts and plain unified diffs above show the text this project held and how it changed. To verify a quotation, compare it against the page itself or against the Internet Archive's copies, which are independent of this project.

Complete captures are held offline rather than mirrored here, so this page shows diffs and excerpts. If a quotation is ever disputed, the full copy can be produced. Ask.
