    This seems to be a growing trend! Cheap mcu’s getting downgraded and secrets extracted from hardware tokens. Can someone point me to research in tamper resistance against fault injection?

    Grindr, who says it “values” privacy, embeds its app with Twitter-owned ad software that exposes users’ precise location with up to 1000+ third parties. Just the tip of the iceberg in this report.

    Has anyone seen this on a firmware dump? I have periodic 0xFFFFFFFFFFFFFFFF's appearing in the dump - over openOCD, on an STM32F105 via a 'definitely official' ST-LinkV2. This appears even when you dump_image or flash read_bank... Thoughts ?

    I order vinyl records online every week. Unfortunately a company named was rewarded monopoly on delivering parcels in my region. I spend at least an hour a week trying to recover lost parcels. So far the deliver rate is below 50%. This makes me sad 😢

    Good research! How was the response from the vendor? Im sure a 3 month embargo period is not going to make much difference for them fixing the issue. They can pretty much inform customers. If a TEE was used could it have been softpatched with fault injection detection capability?
