Internal Pentest

When inside the target network:

  • Start ligolo for pivoting.

  • Run nmap/fping scan to find live hosts.

  • Find open ports on the hosts.

# Scan for live hosts in the network
fping -g <subnet> | grep -v "unreachable" | awk '{print $1}'
nmap -sn -vv <subnet> -oN live_hosts

# Scan top 100 ports with slow speed to avoid issues in tunnel
nmap -F -iL live_hosts -T2 -vv -Pn -oN nmap_scan

  • Enumerate common services.

  • Start with trying to read SMB or NFS shares.

  • Spend time on HTTP websites if available, potentially get foothold on the host.

Found new creds???

  • Enumerate shares again.

  • Check the password on the users you dont know the password of.

  • Try to re-use it everywhere.
