Today I Learned
What did you learn today? Share it with us!
We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.
** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**
Rule 2- Your post subject cannot be illegal or NSFW material.
Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-TIL posts.
Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you vocally harass or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.
Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

According to the page, this is the data that is stored on the chip:
=== CUT === In addition, this memory chip collects a limited set of information about the usage of the product, which might include the following: The date when the toner cartridge was first installed The date when the toner cartridge was last used The number of pages printed using the toner cartridge Page coverage Printing modes used Any printing errors that might have occurred The product model === CUT ===
I don't like that they collect this info, but I don't see any really scary information mentioned there?
Whether I trust HP that is all they store and recover is an entirely other matter ;)
Isn't the point that a hacker can use that memory to export other data?
I don’t quite follow your thought?
You'd first need to get the flash to store other data, requiring malicious firmware modifications.
Like, its not impossible but I really can't see anything nefarious happening to make airgapped printer that would be that big a deal.
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
