Enum4linux is a tool for enumerating information from Windows and Samba systems. It attempts to offer similar functionality to enum.exe formerly available from www.bindview.com.
It is written in PERL and is basically a wrapper around the Samba tools smbclient, rpclient, net and nmblookup. The samba package is therefore a dependency.
sudo apt install enum4linux
enum4linux v0.9.1 (http://labs.portcullis.co.uk/application/enum4linux/) Copyright (C) 2011 Mark Lowe ([email protected]) Simple wrapper around the tools in the samba package to provide similar functionality to enum.exe (formerly from www.bindview.com). Some additional features such as RID cycling have also been added for convenience. Usage: ./enum4linux.pl [options] ip Options are (like "enum"): -U get userlist -M get machine list* -S get sharelist -P get password policy information -G get group and member list -d be detailed, applies to -U and -S -u user specify username to use (default "") -p pass specify password to use (default "") The following options from enum.exe aren't implemented: -L, -N, -D, -f Additional options: -a Do all simple enumeration (-U -S -G -P -r -o -n -i). This option is enabled if you don't provide any other options. -h Display this help message and exit -r enumerate users via RID cycling -R range RID ranges to enumerate (default: 500-550,1000-1050, implies -r) -K n Keep searching RIDs until n consective RIDs don't correspond to a username. Impies RID range ends at 999999. Useful against DCs. -l Get some (limited) info via LDAP 389/TCP (for DCs only) -s file brute force guessing for share names -k user User(s) that exists on remote system (default: administrator,guest,krbtgt,domain admins,root,bin,none) Used to get sid with "lookupsid known_username" Use commas to try several users: "-k admin,user1,user2" -o Get OS information -i Get printer information -w wrkg Specify workgroup manually (usually found automatically) -n Do an nmblookup (similar to nbtstat) -v Verbose. Shows full commands being run (net, rpcclient, etc.) -A Aggressive. Do write checks on shares etc RID cycling should extract a list of users from Windows (or Samba) hosts which have RestrictAnonymous set to 1 (Windows NT and 2000), or "Network access: Allow anonymous SID/Name translation" enabled (XP, 2003). NB: Samba servers often seem to have RIDs in the range 3000-3050. Dependancy info: You will need to have the samba package installed as this script is basically just a wrapper around rpcclient, net, nmblookup and smbclient. Polenum from http://labs.portcullis.co.uk/application/polenum/ is required to get Password Policy info.
