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.

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.

- Ok, thanks I guess

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:
