Because it's inexpensive and not designed to be tamper-resistant. If preventing this type of thing is your goal there are chips out there designed to break irrepairably if tampered with.
- rcxdude 8d agoRp2350s are advertised as having quite a few anti-tamper functions. They had a bounty when it launched to find similar vulnerabilities and they worked to patch the ones that were found. This is a lot more credible than a lot of advertised anti-tamper features.
- crote 7d agoNot really. The RP2350 just adds some bog-standard security features the ESP32 family and plenty of others have had for ages, that's all. The goal of the bounty is to demonstrate that they aren't just a company making toys for hobbyists, and that they can be relied upon by the industry for basic IoT-level products. They are saying "it won't be completely trivial to extract your proprietary firmware", not "use this chip for your next HSM".
