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.

I wish I had bumped into this page a way sooner as it contains most if not all the keyboard symbols I ever looked for: [Wayback/Archive] Unicode: Keyboard Symbols ⌘ ↵ ⌫
The page contains a lot more than just this diagram (which already is a great start):
⎋ ` 1 2 3 4 5 6 7 8 9 0 - = ⌫ ⎀ ⤒ ⇞ ⇥ Q W E R T Y U I O P [ ] \ ⌦ ⤓ ⇟ 🄰 A S D F G H J K L ; ' ↵ ⇧ Z X C V B N M , . / ⇧ ↑ ⎈ ❖ ⎇ ␣ ⎇ ❖ ▤ ⎈ ← ↓ → 🌐 ⌃ ⌥ ⌘
Some more symbols are at these pages:

Next level CAPTCHA which AI engines fail at [Wayback/Archive] Basic Apple Guy on X: “Find the Mac Pro (5th anniversary edition) 🔍 1949 cheese graters, 1 of them is a Mac Pro”
The low res versions are impossible for me, and even the high-res picture is tough.
What is the smallest size you can find the Mac Pro? Picture on the right for reference.

[Wayback/Archive] How To Scale and Crop Images with CSS object-fit | DigitalOcean helped me to crop the picture in Florian Haas on Twitter: alias kubectl=”TZ=Etc/UTC kubectl”; You’re welcome.
The picture itself is 800 * 800 pixels (width * height), but the interesting bits are 400 * 200 around the center. Also it is a lot larger than I wanted.
So I embedded it using this HTML
<img class="alignnone size-full" style="width: 200px; height: 100px; object-fit: cover; object-position: 0 50%;" src="https://archive.ph/frSNu/0f0ebeeb5a4edf048577be89adb866344b303394.jpg" alt="" />
The width made it 25% the original size (because of [Wayback/Archive] object-fit value cover), and half the height so I had to move the [Wayback/Archive]object-position up 50%.
I found this via [Wayback/Archive] image inline css to crop top and bottom – Google Search.
That also found [Wayback/Archive] html – while display image crop Top and Bottom of image using css – Stack Overflow with an example at [Wayback/Archive] Edit fiddle – JSFiddle – Code Playground which is similar to the above solution.

For my link archive as this is environment variable override trick to override DLL loading is not just limited to executables shipping with Windows, but also with other products (likely: virus scanners that run privileged); another alternative is running a local process serving the WebDAV protocol.

Need to write a tool for this that sets/clears the ………… flag in the PE .EXE header.
Officially it is for this:
[Wayback/Archive] IMAGE_FILE_HEADER (winnt.h) – Win32 apps | Microsoft Learn
- IMAGE_FILE_UP_SYSTEM_ONLY
- 0x4000
The file should be run only on a uniprocessor computer.
In practice, this sets the affinity to 1 single CPU core (which is kind of random, and could change each time you start the executable).
This is ideal for code that is known for causing trouble executing on multiple cores, or – more importantly – to disallow core-switching for programs that give best performance when executed on a single core.
Via: [Wayback/Archive] Thread by @0gtweet on Thread Reader App – Did you ever hear about IMAGE_FILE_UP_SYSTEM_ONLY flag in NtHeader->FileHeader->Characteristics of an exe file?

Interesting for both red teams and blue teams: [Wayback/Archive] Hijack Libs
This project provides an curated list of DLL Hijacking candidates. A mapping between DLLs and vulnerable executables is kept and can be searched via this website. Additionally, further metadata such as resources provide more context.
