Nmap releases now include theZenmap graphical user interface for Nmap.If you used the Nmap installer and left the Zenmap field checked,there should be a new Zenmap entry on your desktop and Start Menu.Click this to get started. Zenmap is fully documented inChapter 12, Zenmap GUI Users' Guide. While many users love Zenmap, others preferthe traditional command-line approach to executing Nmap. Here aredetailed instructions for users who are unfamiliar with command-lineinterfaces:

Acunetix is a fully automated penetration testing tool. Its web application security scanner accurately scans HTML5, JavaScript and Single-page applications. It can audit complex, authenticated web apps and issues compliance and management reports on a wide range of web and network vulnerabilities, including out-of-band vulnerabilities.

UNIFIED, this method sniffs all the packets that pass on the cable. You can choose to put or not the interface in promisc mode (-p option). The packet not directed to the host running ettercap will be forwarded automatically using layer 3 routing. So you can use a mitm attack launched from a different tool and let ettercap modify the packets and forward them for you.The kernel ip_forwarding is always disabled by ettercap. This is done to prevent a forward of a packet twice (one by ettercap and one by the kernel). This is an invasive behaviour on gateways. So we recommend you to use ettercap on the gateways ONLY with the UNOFFENSIVE MODE ENABLED. Since ettercap listens only on one network interface, launching it on the gateway in offensive mode will not allow packets to be rerouted back from the second interface.

BRIDGED, it uses two network interfaces and forward the traffic from one to the other while performing sniffing and content filtering. This sniffing method is totally stealthy since there is no way to find that someone is in the middle on the cable. You can look at this method as a mitm attack at layer 1. You will be in the middle of the cable between two entities. Don't use it on gateways or it will transform your gateway into a bridge. HINT: you can use the content filtering engine to drop packets that should not pass. This way ettercap will work as an inline IPS ;)

You can also perform man in the middle attacks while using the unified sniffing. You can choose the mitm attack that you prefer. The mitm attack module is independent from the sniffing and filtering process, so you can launch several attacks at the same time or use your own tool for the attack. The crucial point is that the packets have to arrive to ettercap with the correct mac address and a different ip address (only these packets will be forwarded).

NOTE:you can reverse the matching of the TARGET by adding the -R option to the command line. So if you want to sniff ALL the traffic BUT the one coming or going to you can specify "./ettercap -R /"

ettercap needs root privileges to open the Link Layer sockets. After the initialization phase, the root privs are not needed anymore, so ettercap drops them to UID = 65535 (nobody). Since ettercap has to write (create) log files, it must be executed in a directory with the right permissions (e.g. /tmp/). If you want to drop privs to a different uid, you can export the environment variable EC_UID with the value of the uid you want to drop the privs to (e.g. export EC_UID=500) or set the correct parameter in the etter.conf file.

SSL mitm attack is dependent on TCP traffic redirection to a custom listener port of ettercap. The redir_command_on and redir_command_off configuration variables take care of this (see "etter.conf(5)").However, when ettercap starts, traffic for any source and any destination targeted for the redirectable services will be redirected to ettercap and the SSL stream will be intercepted.This may not be the desired behaviour. Therefore you can adjust the redirect rules after ettercap has been started using the selected user interface.

While performing the SSL mitm attack, ettercap substitutes the real ssl certificate with its own. The fake certificate is created on the fly and all the fields are filled according to the real cert presented by the server. Only the issuer is modified and signed with the private key contained in the 'etter.ssl.crt' file. If you want to use a different private key you have to regenerate this file. To regenerate the cert file use the following commands:

ettercap NG has a new unified sniffing method. This implies that ip_forwarding in the kernel is always disabled and the forwarding is done by ettercap. Every packet with destination mac address equal to the host's mac address and destination ip address different for the one bound to the iface will be forwarded by ettercap. Before forwarding them, ettercap can content filter, sniff, log or drop them. It does not matter how these packets are hijacked, ettercap will process them. You can even use external programs to hijack packet.You have full control of what ettercap should receive. You can use the internal mitm attacks, set the interface in promisc mode, use plugins or use every method you want.

IMPORTANT NOTE: if you run ettercap on a gateway, remember to re-enable the ip_forwarding after you have killed ettercap. Since ettercap drops its privileges, it cannot restore the ip_forwarding for you.

MITM attackThis option will activate the man in the middle attack. The mitm attack is totally independent from the sniffing. The aim of the attack is to hijack packets and redirect them to ettercap. The sniffing engine will forward them if necessary.You can choose the mitm attack that you prefer and also combine some of them to perform different attacks at the same time.If a mitm method requires some parameters you can specify them after the colon. (e.g. -M dhcp:ip_pool,netmask,etc )

The parameter "remote" is optional and you have to specify it if you want to sniff remote ip address poisoning a gateway. Indeed if you specify a victim and the gw in the TARGETS, ettercap will sniff only connection between them, but to enable ettercap to sniff connections that pass thru the gw, you have to use this parameter.

This attack implements DHCP spoofing. It pretends to be a DHCP server and tries to win the race condition with the real one to force the client to accept the attacker's reply. This way ettercap is able to manipulate the GW parameter and hijack all the outgoing traffic generated by the clients.The resulting attack is a HALF-DUPLEX mitm. So be sure to use appropriate filters (see above in the ICMP section).

You have to pass the ip pool to be used, the netmask and the ip of the dns server. Since ettercap tries to win the race with the real server, it DOES NOT CHECK if the ip is already assigned. You have to specify an ip pool of FREE addresses to be used. The ip pool has the same form of the target specification.

If the client sends a dhcp request (suggesting an ip address) ettercap will ack on that ip and modify only the gw option. If the client makes a dhcp discovery, ettercap will use the first unused ip address of the list you have specified on command line. Every discovery consumes an ip address. When the list is over, ettercap stops offering new ip addresses and will reply only to dhcp requests.If you don't want to offer any ip address, but only change the router information of dhcp request/ack, you can specify an empty ip_pool.

BIG WARNING: if you specify a list of ip that are in use, you will mess your network! In general, use this attack carefully. It can really mess things up! When you stop the attack, all the victims will be still convinced that ettercap is the gateway until the lease expires...

It floods the LAN (based on port_steal_delay option in etter.conf) with ARP packets. If you don't specify the "tree" option, the destination MAC address of each "stealing" packet is the same as the attacker's one (other NICs won't see these packets), the source MAC address will be one of the MACs in the host list. This process "steals" the switch port of each victim host in the host list. Using low delays, packets destined to "stolen" MAC addresses will be received by the attacker, winning the race condition with the real port owner. When the attacker receives packets for "stolen" hosts, it stops the flooding process and performs an ARP request for the real destination of the packet. When it receives the ARP reply it's sure that the victim has "taken back" his port, so ettercap can re-send the packet to the destination as is. Now we can re-start the flooding process waiting for new packets.

This options disables the sniffing thread and enables only the mitm attack. Useful if you want to use ettercap to perform mitm attacks and another sniffer (such as wireshark) to sniff the traffic. Keep in mind that the packets are not forwarded by ettercap. The kernel will be responsible for the forwarding. Remember to activate the "ip forwarding" feature in your kernel.

Set a capturing filter in the pcap library. The format is the same as tcpdump(1). Remember that this kind of filter will not sniff packets out of the wire, so if you want to perform a mitm attack, ettercap will not be able to forward hijacked packets.These filters are useful to decrease the network load impact into ettercap decoding module.

BRIDGED sniffingYou need two network interfaces. ettercap will forward form one to the other all the traffic it sees. It is useful for man in the middle at the physical layer. It is totally stealthy since it is passive and there is no way for an user to see the attacker.You can content filter all the traffic as you were a transparent proxy for the "cable".
