(4/N): **From TFTC Podcast (April 1, 2021):**
> "Not a hack, but they had a vulnerability that was self-discovered. So they have a new firmware version, 4.0.1, or is it 0.01? 4.0.1. Yeah. You messed u...

## Conclusion
The evidence suggests:
1. **The vulnerability was introduced intentionally or negligently** in the same massive commit that changed the license from GPL to a proprietary "Bitcoin only" license
2. **Marketing emphasized hardware RNG security** while the actual implementation failed to use it properly
3. **An early patch (4.0.1) may have been a partial fix** but the full scope was not disclosed
4. **The proprietary license likely reduced scrutiny** from the open source community
5. **Claims about "scrutiny" and not "YOLO-ing" code** were contradicted by the actual development practices
Whether this was malicious, incompetent, or a combination is unclear. What is clear is that NVK's public statements about Cold Card's security and development practices do not match the reality of what happened with firmware 4.0.
