tool [options] ...


This manual page briefly documents each of the attack-toolkit6 tools. Not all options are listed here, to see the full list of options of each tool please invoke them with -h.

  • Note that on Debian (if you read this on Debian) command names are prefixed with atk6- , so for example the tool alive6 should be invoked as atk6-alive6. This is a Debian-only modification.

address6 <mac-address/ipv4-address/ipv6-address> [ipv6-prefix]

Converts a mac or ipv4 address to an ipv6 address (link local if no prefix is given as 2nd option) or, when given an ipv6 address, prints the mac or ipv4 address. Prints all possible variations. Returns -1 on errors or the number of variations found.

alive6 <interface> [unicast-or-multicast-address [remote-router]]

covert_send6d <interface> <file>

Writes received covertly content to FILE.

denial6 <interface> <destination> <test-case-number>

fake_mldrouter6 [-l] <interface> <advertise|solicitate|terminate> [own-ip [own-mac-address]]

Announce, delete or solicitate MLD router - yourself or others.

fake_pim6 [-t ttl] [-s src6] [-d dst6] <interface> {<hello> [dr_priority]|{join|prune} <neighbor6> <multicast6> <target6>}

flood_advertise6 <interface>

Flood the local network with neighbor advertisements.

flood_dhcpc6 <interface> [domain-name]

DHCP client flooder. Use to deplete the IP address pool a DHCP6 server is offering. Note: if the pool is very large, this is rather senseless.

flood_mld6 <interface>

implementation6 <interface> <destination> [test-case-number]

Performs some ipv6 implementation checks, can be used to test firewalls too.

implementation6d <interface>

Identifies test packets by the implementation6 tool, useful to check what packets passed a firewall.

inject_alive6 [-ap] <interface>

This tool answers to keep-alive requests on PPPoE and 6in4 tunnels; for PPPoE\nit also sends keep-alive requests. Note that the appropriate environment variable THC_IPV6_{PPPOE|6IN4} must be set. Option -a will actively send alive requests every 15 seconds. Option -p will not send replies to alive requests.

inverse_lookup6 <interface> <mac-address>

Performs an inverse address query, to get the IPv6 addresses that are assigned to a MAC address. Note that only few systems support this yet.

kill_router6 <interface> <target-ip>

Announce that target router is going down to delete it from the routing tables. If you supply a '*' as target-ip, this tool will sniff the network for RAs and immediately send the kill packet.

ndpexhaust26 <interface> [-acpPTUrR] [-s sourceip6] <target-network>

Flood the target /64 network with ICMPv6 TooBig error messages. This tool version is manyfold more effective than ndpexhaust6. -a add a hop-by-hop header with router alert. -c do not calculate the checksum to save time. -p send ICMPv6 Echo Requests. -P send ICMPv6 Echo Reply. -T send ICMPv6 Time-to-live-exceeded. -U send ICMPv6 Unreachable (no route). -r randomize the source from your /64 prefix. -R randomize the source fully. -s sourceip6 use this as source ipv6 address.

ndpexhaust6 <interface> <target-network>

Randomly pings IPs in target network.

node_query6 <interface> <target-ip>

Sends an ICMPv6 node query request to the target and dumps the replies.

parasite6 <interface> [fake-mac]

This is an "ARP spoofer" for IPv6, redirecting all local traffic to your own system (or nirvana if fake-mac does not exist) by answering falsely to Neighbor Solicitation requests, specifying FAKE-MAC results in a local DOS.

passive_discovery6 <interface> [scriptname]

Passively sniffs the network and dump all client's IPv6 addresses detected. If scriptname is supplied, it is called with the detected IPv6 address as first and the interface as second parameters.

randicmp6 <interface> <target-ip>

Sends all ICMPv6 type and code combinations to target.

redir6 <interface> <src-ip> <target-ip> <original-router> <new-router> [new-router-mac]

Implant a route into src-ip, which redirects all traffic to target-ip to new-ip. You must know the router which would handle the route. If the new-router-mac does not exist, this results in a DOS.

redirsniff6 <interface> <victim-ip> <destination-ip> <original-router> [<new-router> [new-router-mac]]

Implant a route into victim-ip, which redirects all traffic to destination-ip to new-router. You must know the router which would handle the route. If the new-router and new-router-mac does not exist, this results in a DoS.

rsmurf6 <interface> <victim-ip>

Smurfs the local network of the victim. Note: this depends on an implementation error, currently only verified on Linux (fixed in current versions). Evil: "ff02::1" as victim will DOS your local LAN completely.

smurf6 <interface> <victim-ip> [multicast-network-address]

Smurf the target with ICMPv6 echo replies. Target of echo request is the local all-nodes multicast address if not specified.

sendpees6 <interface> <key_length> <prefix> <victim-ip>

Craft your special ICMPv6 echo request packet.

thcsyn6 [-AcDrRS] [-p port] [-s source-ip6] <interface> <target> <port>

Flood the target port with TCP-SYN packets. If you supply "x" as port, it is randomized.

toobig6 <interface> <target-ip> <existing-ip> <mtu>

Implants the specified mtu on the target
