Itried to issue PCL commands to my printer, but they always get a timed out error.
So i decided to tinker a bit before spending a shitload of money into toners or new printers, i'm using this tool to try access and issuing commands to the printer, the connection gets succesfully enstablished. After that i can issue commands in three different languages: PS and PJL doesn't seem to do anything, with PCL at least i see a Device: Unknown printer but all the commands i issue seem to simply not be taken in consideration from the printer, in any of the 3 languages, giving a Command execution failed (timed out) error.

what can ya do with a hacked printer? (jetdirect? port 9100 vuln)
my friend that owns a coffee shop asked me to poke around on his network to look for vulnerabilities in exchange for some free coffees and i saw that they had 9100 open, wasn't familiar with it so played around and found out about PRET which gave me access to his HP printer, with transversal you can gain access to the file system etc and from what i read you can open a root shell on another port, would the scope be limited to the printer, or can the printer be used as a vector to gain access to other systems connecting to said printer?

Am I wearing a tin foil hat or is a public facing print server an issue?
Preferable you don't want it accessible from the internet at all. Using stuff like the Printer Exploitation Toolkit (PRET), people can get up to some nasty stuff on a public accessible (insecure) printer : https://github.com/RUB-NDS/PRET

CVE-2022-23968: Xerox vulnerability allows unauthenticated users to remotely brick network printers
You'll love PRET then. It can also brick printers and do all kinds of other fun stuff with them.

- Someone came into my job today asking if they have a virus because propaganda from this subreddit started coming out of their printer
- These came off of our printer at work tonight.

Mass Scanning
Can I get banned for mass scanning with https://github.com/robertdavidgraham/masscan or does it slow down any other vms from other persons?

Has anyone ever had their homelab or network hacked? What happened?
Nope, this doesn't work any more. Shodan checks all ports (so any attackers using data from Shodan already know which ports you have open), and tools like masscan (https://github.com/robertdavidgraham/masscan) let you portscan the entire IPv4 address space in less than 10 minutes.

My home server is frustrating me. Please help me, home server wizards.
Changing the default port does nothing for security. It only prevents some basic brute force or default password scripts. Anyone is able to scan for it in no time anyway (https://github.com/robertdavidgraham/masscan).

Should I be Concerned?
But it should blow away the far-too-common belief that no-one's after you because you're not interesting enough. IPv4 is smaller than we think. It is not difficult to scan the entire ipv4 space in minutes. And every single one of those is going to knock your door on the way past.

Ask HN: Looking for an Old Article
I'm not sure about the article, but the blazingly-fast IP scanner sounds a lot like Masscan. It can scan the entire Internet in 5 minutes and has received a lot of press: https://github.com/robertdavidgraham/masscan . https://rushter.com/blog/how-masscan-works/ is one of many articles about it.

Is my Synology getting port-scanned?
Here's an except from the masscan docs:
- I was hit with ransomware in my Plex server and I'm not sure where it came from. Could a DMZ be the cause?
- PSA: Masscan has changed his IP. Please block the new one on your firewall! Its likely our vps reporting worked.
