Dammm. I don't what to say, multi Sig plus waiting before updating is the take away I suppose.

But there only acknowledging something strange is going on. That haven't identified a root cause..
Summary of the Changelog for Coldcard Mk3 Firmware: 4.0.0 → 4.0.1 Version 4.0.0 — March 17, 2021 Described by Coinkite as "Major Internal Improvements — All New Code, Same Great Features". This was effectively a ground-up rewrite of the firmware internals. The version history page references ckcc-backup.txt (the encrypted backup file format) as a key associated feature. The blog post title frames it as keeping the same user-facing functionality while replacing the underlying codebase. Version 4.0.1 — March 29, 2021 (12 days later) The official version history page states plainly: "Fixes security issue in v4.0.0. (3.x.x Unaffected)"
It seems like the answer is yes so far but this is only speculation. Best to be extremely cautious with all coldcard products at this time. I personally know people who were hit and lost funds.

Lol. Do not trust Coinkite products. (They aren't open source by the way)

I’ve been exploring different perspectives in the crypto space, and I’ve come across Paul Jon's content a few times. What stands out to me is his focus on risk management and staying patient rather than chasing quick profits. I don’t think there’s a single ‘perfect’ approach to trading, but it’s useful to learn from different viewpoints and then build your own strategy over time. Some of his ideas seem practical, especially for people who are still trying to understand market behavior. At the end of the day, everyone has to test what works for them and stay consistent. The market is always changing, so having a balanced mindset and being open to learning is probably more important than following any one method blindly. Just sharing my thoughts based on what I’ve seen so far.” Where to find him Telegram 👇 "Pjtradinghub" image
