The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Simos18 Supplier Bootloader (SBOOT) Exploit: Reading Boot Passwords
After the Seed/Key process was figured out, the CRC exploit was very obvious as the bounds checking is blatantly broken. https://github.com/resilar/crchack came in handy to take the CRC + unknown data and back-generate the correct data used to produce the CRC.

Simos18 Supplier Bootloader (SBOOT) Exploit: Reading Boot Passwords
As for my process: I loaded up SBOOT in Ghidra using a register map I built using available TriCore toolchain information: https://github.com/bri3d/ghidra_tc1791_registers . Then I literally just, well, read the code. The GPT timing comparisons were easy to find from access to the GPTA registers, but it took a long time to realize the base frequency the PLLs were locked at (8.75Mhz) to translate the cycle-timing back into real timing.
