# Jethro's Braindump
4+
5+
This braindump is generated via [ox-hugo][ox-hugo] and uses the
6+
[cortex][cortex] theme.
7+
8+
The org files used to generate the markdown files are also hosted here
9+
for posterity. They can be found in [the org folder][org].
10+
11+
## Installation instructions
12+
13+
I use the [Ninja](https://ninja-build.posts/ "Ninja") build tool to convert my Org
14+
files into Markdown locally. This is so that only changed Org files get
15+
reprocessed into Markdown files. Ninja spawns many Emacs instances in batch mode
16+
running `ox-hugo`, parallelizing the job of exporting the Org files.
17+
18+
To convert all Org files into Markdown, run:
19+
20+
```bash
21+
./build.py
22+
```
23+
24+
`build.py` is simple enough to inspect. Once the Markdown files are generated,
25+
we can use Hugo to generate the website.
26+
27+
Install [hugo][hugo]. E.g., on a Mac with Homebrew:
28+
29+
$ brew install hugo
30+
31+
Make sure the submodule containing the Hugo theme is installed:
32+
33+
$ git submodule init
34+
$ git submodule update
35+
36+
Now run hugo to generate the files (find them in `/public`):
37+
38+
$ hugo
39+
40+
Or run the following to get an immediately browsable website on localhost:
41+
42+
$ hugo serve
43+

# Hi! {#hi}
10+
11+
I'm kdbed, and you've chanced upon my braindump.
12+
This website contains my working notes accumulated over some years. They're in a
13+
really messy transition state: most of them are literature notes, and there are
14+
close to no conceptual notes, which I intend to start taking soon.
15+
16+
I also haven't made good entry-points to my brain yet, but you can start hopping
17+
around by going to the [full index](/posts/).
18+
19+
Have fun!

Two key attacks on [Kerberos]({{<relref "posts/kerberos.md#" >}}) security in Active Directory include [kerberoasting]({{<relref "posts/kerberoasting.md#" >}}) and AS-REP Roasting. Kerberoasting typically requires credentials on the domain to authenticate with. There is an option for an account to have the property “Do not require Kerberos preauthentication” or UF\_DONT\_REQUIRE\_PREAUTH set to true. AS-REP Roasting is an attack against Kerberos for these accounts.

Use the [Impacket]({{<relref "posts/impacket.md#" >}}) tool `GetNPUsers.py` to try to get a hash for each user

```shell

The hash is quickly cracked with `hashcat`.
