Disappointed that they did nothing to probe the onboard MCUs to see if they could get it to leak anything, and just dismissed that with "we expect it to get high marks there." This seems an awfully low quality report from an infosec company. I was hoping to see an audit of the controllers onboard to see if (and if so, how much effort) they can extract onboard secrets, because after all that's the whole purpose of this device, to act as a secrets repository.

First line of the page: Yubikey is a curiosity-driven side project for us and we have plans to dig a bit further into hardware as time permits. If anybody could confidentially help with NXP datasheets, it would be much appreciated.

I guess they could have waited until they had more to publish it, but I found it interesting regardless

NXP processor manuals and datasheets are on NXP's website. Just google for "13xx User Manual". Here's a link to 13xx series user manual[1]

(I've just finished a year working on an embedded project using NXP 13xx series processors, and NXP's documentation is top notch.)
