Can it authenticate with hashes instead of passwords?

Yes. Pass an NTLM hash with --hash for pass-the-hash, or use --kerberos and --use-kcache for ticket-based authentication.

How do I avoid locking out accounts during a spray?

Set --fail-limit, --ufail-limit, and --gfail-limit so the run halts before tripping a domain lockout policy.

How do I enumerate shares and users over SMB?

Authenticate with --username and --password (or --hash), set -d for the domain, then add --shares or --users. Add --pass-pol to dump the password policy.

What is the difference between nxc and netexec?

They are the same project. The maintained binary is commonly invoked as nxc; netexec is the package and library name. On Trickest the node is labeled netexec.

Can it dump SAM or NTDS?

Yes. --sam dumps SAM hashes from targets you can reach as admin. --ntds dumps NTDS.dit from domain controllers with a chosen method such as drsuapi or vss.

overview

What netexec does

netexec, also shipped as nxc, automates security assessment of large networks. Point it at a target and a protocol, supply credentials or hashes, and it authenticates, enumerates, and acts across many hosts at once. It speaks SMB, LDAP, MSSQL, WMI, SSH, VNC, FTP, WinRM, and RDP, so one CLI covers a mixed environment.

Most of its power is in Active Directory and credential work. Enumerate domain users, groups, computers, and password policy, spray credentials with per-host and global fail limits, dump SAM, LSA, and NTDS, run modules, spider shares, and execute commands. Pass-the-hash, Kerberos, and local-auth flows are first class.

Wire it after host and port discovery so authentication only hits live services, and scope each run to one protocol to keep output readable. On Trickest it lands as a Network node that takes a target or target file plus credentials and writes a file and a folder of results.

use cases

Where netexec fits

Spray credentials across a domain

Test username and password or hash sets over SMB or LDAP with fail limits so a spray finds valid logins without locking accounts out.

Enumerate Active Directory

Pull domain users, groups, computers, password policy, and shares from a domain controller to map the environment before deeper work.

Dump credential material

Extract SAM, LSA, and NTDS secrets from hosts you have access to, feeding the harvested hashes back into further pass-the-hash assessment.

Run modules and remote commands

Execute a chosen command or PowerShell across reachable hosts, or load a module, to validate access and gather data at scale.

guidance

Choosing netexec

Use netexec when you have network access and credentials and need to enumerate or assess many hosts over a service protocol. It is an authenticated assessment tool, not a discovery scanner, so run host and port discovery first and scope each run to one protocol.

medusa

Parallel login brute forcer across many protocols. netexec adds AD enumeration, dumping, and command execution on top of credential testing.

hydra

Fast network login cracker. netexec is broader, pairing credential spraying with post-auth enumeration and modules.

nuclei

Template-based vulnerability scanner. netexec focuses on authenticated network-service access rather than web checks.

faq

netexec questions

LDAP, MSSQL, SMB, WMI, SSH, VNC, FTP, WinRM, and RDP. You pass the protocol as a positional argument and the rest of the flags adapt to it.

Run netexec yourself

A target list feeds naabu to find live SMB hosts, then netexec authenticates and enumerates them before the results land as a queryable output.

Facts on this page come from the live Trickest tool library.
