https://mstdn.maud.io/@omasanori@cwebber as to the chip's size, IPMI provides most of the functionality, could this just be a IPMI backdoor chip?
Given how insecure IMPI was, especially in this time frame, the chip could have just done some basic firewall bypass callout to let the attackers talk to the IMPI and they could have then simply hacked IMPI.
