What happened and what to do
On June 28, 2026, Quarkslab published a black-box analysis of Xiaomi’s MJA1 secure chip. The work covered hardware identification, I2C traffic capture, flash extraction and firmware reverse engineering; the researchers mapped the command protocol and assessed security properties.
A company developing or integrating devices can apply a similar approach to assess components without complete documentation. This may include hardware and firmware inventories, controlled communication capture, protocol analysis and findings documentation to inform security decisions and remediation.
