Use when attacking a network or moving laterally — L2/L3 poisoning (LLMNR/mDNS, ARP/DHCP, mitm6), coercion + NTLM relay (CVE-2025-33073), TUN pivoting (Ligolo-ng/Chisel), MitM, network-service RCE (CVE-2024-38077), WPA2/WPA3 wireless.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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 | Technique | ATT&CK | CWE | Reference | Script | |-----------|--------|-----|-----------|--------| | LLMNR/NBT-NS/mDNS poisoning (Responder) | T1557.001 | CWE-300 | references/l2-attacks.md | scripts/responder_loot_parser.py | | ARP spoofing MitM | T1557.002 | CWE-300 | references/l2-attacks.md | scripts/bettercap_mitm.sh | …

How to install
mdr add hypnguyen1209/offensive-claude/network-attack@sha256:fd4f2f5e4504c738The line at the top of this page pins the label git:20260916.d4cb295, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
