For my link archive: [Wayback/Archive] Payload Box.
It has lots of examples on payloads for various kinds of injections that are excellent teaching material.
Covered are Cross Site Scripting (XSS), SQL Injection, Server Side Template Injection, RFI/LFI, Command Injection, CSV Injection, Directory, Open Redirect and XML External Entity (XXE) Injection.
Got there when inspired by:

Having had to use Mimikatz a few times in the past, I was not aware of the history.
So I was glad to find this elaborate article [Wayback/Archive] Mimikatz and password dumps | Ivan’s IT learning blog and the video (embedded after the signature). [Wayback/Archive] How to fix mimikatz null password in Windows 10 | WORKING 2019!!! – YouTube
Besides the history, it also explains why sometimes you only get hashes and other times you do get plain text passwords.
Recommended reading.

[Wayback/Archive] Dumpsterdiving for network access :: Jilles.com
Just scaring people by telling them I could simply login to your network when you throw away you broken Smart light was not very credible. And eventhough people were kindly speaking up for me I would still like to illustrate how simple it is.

On my research list [Wayback/Archive] HInvoke and avoiding PInvoke | drakonia’s blog.
A very minimalistic approach of calling .net runtime functions or accessing properties using only hashes as identifiers. It does not leave any strings or import references since we dynamically resolve the required member from the
mscorlibassembly on runtime.

Simple (but fully working) code for
NPLogonNotify(). The function obtains logon data, including cleartext password.
[Wayback/Archive] PSBits/PasswordStealing/NPPSpy at master · gtworek/PSBits has been used in the wild since about 2022 (the code is from 2020).
The code is a ~100 line C file resulting in a DLL exporting the NPGetCaps() and NPLogonNotify() functions.

Remember to adapt what you pack and tailor it for each red team training event as the blue team should expect the unexpected. Believable pretext is key.

Many organisations train their personell with phishing attempts from domains that are different from the one the organisation uses.
The mantra is: only respond to emails (or clicking links in them) from domains you know.
Microsoft sent (still sends?) account expiration emails for various *.microsoft.com, *.visualstudio.com and other Microsoft domains like this:
