Connect to an SMB share

Use the high-level SMBConnection API to interact with remote shares:
from impacket.smbconnection import SMBConnection

conn = SMBConnection("TARGET", "192.168.1.10")
conn.login("username", "password")

# List files in a share
files = conn.listPath("SHARE", "/*")
for f in files:
    print(f.get_longname())

Use built-in tools

Impacket includes 68+ example scripts for common security operations:
# Dump credentials from a remote system
secretsdump.py domain/user:[email protected]

# Execute commands remotely
wmiexec.py domain/user:[email protected]

# Extract Kerberos tickets
GetUserSPNs.py domain/user:password -dc-ip 192.168.1.5
