       aireplay-ng - inject packets into a wireless network to generate traffic


       aireplay-ng [options] <replay interface>


       aireplay-ng  is used to inject/replay frames.  The primary function is to generate traffic
       for the later use in aircrack-ng  for  cracking  the  WEP  and  WPA-PSK  keys.  There  are
       different  attacks  which  can  cause  deauthentications  for the purpose of capturing WPA
       handshake data, fake authentications, Interactive packet replay, hand-crafted ARP  request
       injection  and  ARP-request  reinjection.  With  the  packetforge-ng tool it's possible to
       create arbitrary frames.

       aireplay-ng supports single-NIC injection/monitor.
       This feature needs driver patching.

       Attack modes:

       -0 <count>, --deauth=<count>
              This attack sends deauthentication  packets  to  one  or  more  clients  which  are
              currently  associated  with a particular access point. Deauthenticating clients can
              be done for a number of reasons: Recovering a hidden ESSID. This is an ESSID  which
              is  not  being  broadcast. Another term for this is "cloaked" or Capturing WPA/WPA2
              handshakes by forcing clients to reauthenticate or Generate ARP  requests  (Windows
              clients sometimes flush their ARP cache when disconnected).  Of course, this attack
              is totally  useless  if  there  are  no  associated  wireless  client  or  on  fake

       -1 <delay>, --fakeauth=<delay>
              The  fake  authentication  attack  allows  you  to  perform  the  two  types of WEP
              authentication (Open System and Shared Key) plus associate with  the  access  point
              (AP).  This  is  useful  is  only useful when you need an associated MAC address in
              various aireplay-ng attacks and there is currently no associated client. It  should
              be  noted  that  the  fake authentication attack does NOT generate any ARP packets.
              Fake authentication cannot be used to authenticate/associate with  WPA/WPA2  Access

       -2, --interactive
              This  attack  allows you to choose a specific packet for replaying (injecting). The
              attack can obtain packets to replay from two sources. The first being a  live  flow
              of packets from your wireless card. The second being from a pcap file. Reading from
              a file is an often overlooked feature of aireplay-ng. This allows you read  packets
              from other capture sessions or quite often, various attacks generate pcap files for
              easy reuse. A common use of reading a file containing a packet  your  created  with

       -3, --arpreplay
              The  classic  ARP  request  replay attack is the most effective way to generate new
              initialization vectors (IVs), and works very reliably. The program listens  for  an
              ARP  packet then retransmits it back to the access point. This, in turn, causes the
              access point to repeat the ARP packet with a new IV. The  program  retransmits  the
              same  ARP  packet  over  and  over. However, each ARP packet repeated by the access
              point has a new IVs. It is all these new IVs which allow you to determine  the  WEP

       -4, --chopchop
              This  attack,  when  successful,  can decrypt a WEP data packet without knowing the
              key. It can even work against dynamic WEP. This attack does not recover the WEP key
              itself,  but  merely  reveals  the  plaintext.  However, some access points are not
              vulnerable to this attack. Some may seem vulnerable at first but actually drop data
              packets  shorter  that  60 bytes. If the access point drops packets shorter than 42
              bytes, aireplay tries to guess the rest of the missing data, as far as the  headers
              are  predictable.  If  an  IP  packet  is  captured,  it additionally checks if the
              checksum of the header is correct after guessing the  missing  parts  of  it.  This
              attack requires at least one WEP data packet.

       -5, --fragment
              This  attack,  when  successful,  can  obtain  1500  bytes  of  PRGA (pseudo random
              generation algorithm). This attack does not recover the WEP key itself, but  merely
              obtains the PRGA. The PRGA can then be used to generate packets with packetforge-ng
              which are in turn used for various injection attacks. It requires at least one data
              packet to be received from the access point in order to initiate the attack.

       -6, --caffe-latte
              In general, for an attack to work, the attacker has to be in the range of an AP and
              a connected client (fake or real). Caffe Latte attacks allows one to gather  enough
              packets  to  crack a WEP key without the need of an AP, it just need a client to be
              in range.

       -7, --cfrag
              This attack turns IP or ARP packets from a client  into  ARP  request  against  the
              client.  This  attack works especially well against ad-hoc networks. As well it can
              be used against softAP clients and normal AP clients.

       -8, --migmode
              This attack works against Cisco Aironet access points configured in  WPA  Migration
              Mode,  which enables both WPA and WEP clients to associate to an access point using
              the same Service Set Identifier (SSID).  The program listens for a WEP-encapsulated
              broadcast ARP packet, bitflips it to make it into an ARP coming from the attacker's
              MAC address and retransmits it to the access  point.  This,  in  turn,  causes  the
              access  point  to  repeat  the ARP packet with a new IV and also to forward the ARP
              reply to the attacker with a new IV. The program retransmits the  same  ARP  packet
              over  and  over. However, each ARP packet repeated by the access point has a new IV
              as does the ARP reply forwarded to the attacker by the  access  point.  It  is  all
              these new IVs which allow you to determine the WEP key.

       -9, --test
              Tests injection and quality.



              -  Can  obtain  the  full  packet  length  of  1500  bytes  XOR. This means you can
              subsequently pretty well create any size of packet.
              - May work where chopchop does not
              - Is extremely fast. It yields the XOR stream extremely quickly when successful.

              - Setup to execute the attack is more subject to the device drivers.  For  example,
              Atheros  does  not  generate the correct packets unless the wireless card is set to
              the mac address you are spoofing.
              - You need to be physically closer to the access point since  if  any  packets  are
              lost then the attack fails.


              - May work where frag does not work.

              - Cannot be used against every access point.
              - The maximum XOR bits is limited to the length of the packet you chopchop against.
              - Much slower then the fragmentation attack.
