SYNOPSIS

amap [Mode] [Options] <target> <port/portrange> [<port> ...]

DESCRIPTION

Amap is a scanning tool that allows you to identify the applications that are running on a specific port or ports. This is achieved by connecting to the port(s) and sending trigger packets. These trigger packets will typically be an application protocol handshake. Many network daemons will only respond to the correct handshake (i.e. SSL). Amap then looks up the response in a list and prints out any match it finds. Amap supports tcp and udp protocols, regular and SSL-enabled ASCII and binary protocols and a variety of options are at your disposal to control the behaviour of the tool. It can take an nmap machine readable output file as its input file and can log to a file and screen.

Why use our tool? Well, when portscanning a host, you will be presented with a list of open ports. In many cases, the port number tells you what application is running. Port 25 is usually SMTP, port 80 mostly HTTP. However, this is not always the case, and especially when dealing with proprietary protocols running on non-standard ports you will not be able to determine what application is running. With amap, you will be able to identify that SSL server running on port 3445 and some oracle listener on port 23. Also, it will actually do an SSL connect if you want and then try to identify the SSL-enabled protocol!

Please also see amapcrap -h for an additional tool for ports who do not give any output.

MODES

amap can be run in three different modes:
-A Map applications: send triggers and analyse responses (default). All options can be used in this mode.
-B Just grab banners, do not send triggers. Only a few commandline options are used from the set when run this mode. They are maked below as "(Banner)"
-P No banner, application, stuff - be a (full connect) port scanner! Only a few commandline options are used from the set when run this mode. They are maked below as "(Portscan)"
-W This is the Web Online Update mode. When specifying this option, all other options except -D are ignored, and the application fingerprints and triggers are updated from the thc.org web site.

OPTIONS

Options can also be seen by typing ’amap -h’. Here follows an explanation of all options.
HOSTS AND PORTS (all modes)
-i <file>
  This makes amap read its hosts and ports from the specified file. The file must be
Generated by nmap, using the -oM <file> option of nmap. It doesn’t matter if you have multiple hosts and mixed tcp and udp ports in the file: amap reads them all.
lt;target> and <port/portlist>
  Target can be an IP address or fully qualified host name. A port can be any number between 1 and 65535, ranges (e.g. 1-65535) are also supported. You can specify as many ports on the command line as you want. Ports are by default TCP (see -u option below).
GENERAL OPTIONS
None of these are required but some can be quite useful.
Note that all options can be used in amap’s default mode (-A), the banner grab (-B) and portscan modes (-\P) support only those options which are marked as such.
-u
  Ports specified on commandline are UDP (default is TCP). (Modes: Amap, Banner, Portscan)
-6 Use IPv6, not IPv4
-1 Only send triggers to a port until 1st identification. Speeeeed!
-v Verbose. Usually not used, but gives detailed info on the screen as to what connections are made to what ip’s/ports. Don’t use twice. You will be bored to death with even more stupid uninteresting information. (Modes: Amap, Banner, Portscan)
-q Quiet. Has got nothing to do with the "-v" option :-) If the -q option is applied, all closed and timed out ports are NOT marked as unidentified, and are not reported at all.
-d Make a hex dump of all received responses. The default is to only print unrecognised responses.
-U Do not dump unrecognized responses. (see option above)
-b Print ACSII banners (if one is received).
-o <file>
  Log the output of amap to <file>. (Modes: Amap, Banner, Portscan)
-m <file>
  Make the log file output (-o option) machine readable (colon seperated). (Modes: Amap, Banner, Portscan)
-D <file>
  Triggers and responses are read by default from appdefs.trig and appdefs.resp. By specifying for instance ’-D trojans’ it will read triggers and responses from trojans.trig and trojans.resp. It can be very usefull if you only want to scan for certain applications. Please take a look at the appdefs files to see what the format of these files is (it’s pretty simple, you shouldn’t have any trouble adding your own triggers and responses, which you are encouraged to do, btw).
SCANNING OPTIONS
  These options influence the behaviour of amap when scanning.
-p <proto>
  This specifies a single protocol trigger to send. The name of the protocol must match one of the first fields of the lines in the trigger file. For instance, ’-p SSL’ will scan only for SSL enabled port. However, if by chance other protocols are also indentified, they will be printed.
-S Do NOT NOT look behind an SSL port. Otherwise amap will reconnect later to identify the service running behind the ssl wrapper.
-R Do NOT identify RPC service. Otherwise amap will connect many times to identify the exact rpc service type and version. This can be time consuming.
-c n Open ’n’ parallel tasks (connections). The default is 32, the maximum 256. (Modes: Amap, Banner, Portscan)
-C n If a TCP connect timed out (did not finnish in "-T n" time), how often should be retried the connect? This is by default 3. (Modes: Amap, Banner, Portscan)
-T n Causes amap to wait upto ’n’ seconds for a successful TCP connect. Default is 5 seconds, but this can be too few sometimes when scanning over a slow link, and too long on a LAN. (Modes: Amap, Banner, Portscan)
-t n Causes amap to wait upto ’n’ seconds for a response. Default is 5 seconds, but this can be too few sometimes when scanning over a slow link, and too long on a LAN. (Modes: Amap, Banner)
-H Skip potentially harmful triggers. Some daemons and applications will crash when receiving long or unexpected binary input. -H skips triggers marked as potentially harmful. See appdefs.trig for information on how to mark a trigger as harmful.
