The recent blog post points out and reminds us of the complexity and the existence of re-writable firmware. It also mentions CRC as proof of secure data management. Well, I’m no expert but CRC just means reliable data integrity not security. Are the firmware updates pushed by WayTools cryptographically signed? If not, what prevents a hacker from pushing a malicious update into the keyboard with something like a keylogger or other sort of malware.
Based upon my reading of the blog I would guess they are not signed. A Yes or No on that would really help clear things up. Apparently Apple struggled with this since it took so long for them to allow third-party software keyboards (and then they are disabled in password fields).
