Exploiting Network Printers

The idea of a paperless office has been dreamed of for more than three decades. However, nowadays printers are still one of the most essential devices for daily work and common Internet users. Instead of removing them, printers evolved from simple devices into complex network computer systems, installed directly into company networks, and carrying considerable confidential data in their print jobs. This makes them to an attractive attack target.

What if you get a command execution error with pret?

[@madkvideo]

Have there been any measures taken in these 3 years?

[@ahmadmansour1171]

its about version ... today i learned it .. gone to shodan and it worked

[@arghyl]

nope printers are as vulnerable as ever.

[@seif9923]

nope, even after 5 years

[@Tularis]

If I only use PCL can I just disable PostScript and PJL?

[@0xbenedikt]

But all they needed to do is sandbox the Postscript interpreter. Reset it after every job, implement write limiting, protect the local file system and enforce a maximum execution time.

[@rajughorai3909]

Great

[@victorselve8349]

Bochum and IT security 🤣 This recently got quite funny.

[@m.preacher2829]

why?

[@Scarecrow-zl3yt]

its a known fact they can hack printers to gather info from ur pc and they are just now getting around to have something done about this . wow

[@endofthelinejoel]

Hey, Black Hat. Why did you recently delete all comments from your 'making diversity a priority' video ( kzbin.info/www/bejne/qH6bYnyoZdh5b6M ) , freeze the like/dislike field, and then lock the comments? Because of the hugely negative feedback, that's why. You may not like the feedback, but at least have the guts to face OPEN criticism there.

[@deceps]

Hahahahahaha

[@Nerobyrne]

People who make diversity a priority cannot face open criticism. I don't like generalizing but this is always the case so far. First this, then the censorship, then the firing, then the organization hits the dirt and everyone asks themselves what they did wrong.

[@therealgreg5653]

Love calling out companies for posting blatant racist which is all DEI is

[@ciscomalo5731]

[@CarlosLopez-hu5sw]

[@sir_john_hammond]

Access to file system, snore... if you hackers will do something USEFUL like releasing free ink cartridge chip reset software, you would be heroes to the entire globe.

[@bbuggediffy]

What have you published lately? What have you given talks on lately?

[@bencesarosi7718]

You don't really need those. Not bad enough of an itch. Just buy a refill kit for peanuts and ignore the printer complaining.

[@-_unknownlegend_-7627]

This comment is a bit old but hackers use security testing "applications" to hack/exploit something, there aren't many or any "applications" that are helpful for someone, well hacking is just testing security of something but doing it illegally.

[@XBGamerX20]

I'm getting ready to hack some printers and promote PewDiePie lol

[@damstachizz]

Too weak to leave the comments and rating open on any of your videos that aren't liked, huh? 'wah they disagree with my opinion'

[@damejelyas]

i don't know why but his voice is shaking, shit.
