They use the small flash inside the DRM chip in the cartridge to store the telemetry, then the e-waste companies are paid by HP to read and send to the mothership the contents of the chips sent to recycle

Lets say a malicious actor infiltrates the supply chain and loads custom firmware on the device. Somehow the malicious firmware avoids detection, and is installed in a secured environment.
What can be exfiltrated in the flash is probably pretty limited, but top 5 usernames and their top 5 IP-addresses, perhaps as many jobtitles as can be stored correlated to the above information. And now the attacker can extrapolate all sorts of classified information.
ok what if they just installed a 4G transmitter. Would be way less work and a higher success rate for retrieving anything
And easy to catch in an environment so secure that airgapping is necessary and supply chain infiltration is worthwhile
