Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

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.

thought this was really fitting

- 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.

4 AD Attacks and How to Protect Against Them
Mimikatz
-
Compromising Plaintext Passwords in Active Directory
Typically, Mimikatz is used to extract NTLM password hashes or Kerberos tickets from memory. However, one of its lesser-known capabilities is the ability to extract plaintext passwords from dumps created for the LSASS process. This means that an attacker can compromise plaintext passwords without running any nefarious code on domain controllers. Dump files can be created interactively or using ProcDump , and in either case, the activity is unlikely to be flagged by anti-virus software. Once the dumps are created, they can be copied off the domain controller and the plaintext credentials can be harvested using Mimikatz offline.

How to Detect Pass-the-Ticket Attacks
Mimikatz can be used to perform pass-the-ticket, but in this post, we wanted to show how to execute the attack using another tool, Rubeus , lets you perform Kerberos based attacks. Rubeus is a C# toolset written by harmj0y and is based on the Kekeo project by Benjamin Delpy, the author of Mimikatz .

What is DCShadow Attack and How to Defend Against It
What is DCShadow? DCShadow is a command in the Mimikatz tool that enables an adversary to register a rogue domain controller and replicate malicious changes across the domain.

Stealing User Passwords with Mimikatz DCSync
Mimikatz provides a variety of ways to extract and manipulate credentials, but one of the most alarming is the DCSync command. Using this command, an adversary can simulate the behavior of a domain controller and ask other domain controllers to replicate information — including user password data. In fact, attackers can get any account’s NTLM password hash or even its plaintext password, including the password of the KRBTGT account, which enables them to create Golden Tickets.
-
Domain Compromise with a Golden Ticket Attack
Using Mimikatz , it is possible to leverage the password of the KRBTGT account to create forged Kerberos Ticket Granting Tickets (TGTs) which can be used to request Ticket Granting Server (TGS) tickets for any service on any computer in the domain.

Manipulating User Passwords with Mimikatz
Using the ChangeNTLM and SetNTLM commands in Mimikatz , attackers can manipulate user passwords and escalate their privileges in Active Directory . Let’s take a look at these commands and what they do.

Extracting Service Account Passwords with Kerberoasting
Mimikatz will extract local tickets and save them to disk for offline cracking. Simply install Mimikatz and issue a single command:
