NetExec is a framework for concurrent credential spraying and remote command execution across network protocols. It provides input sanitization and command parsing to reduce injection risks, a plugin-based protocol abstraction that dispatches credentials and commands uniformly regardless of transport, and session and token lifecycle management for long-running multi-command operations. Results from concurrent executions are collected and normalized through a result aggregation pipeline.
The framework includes a concurrent job scheduler that manages worker threads for parallel execution across many hosts, and a credential spraying engine with configurable delay and lockout detection to avoid service disruption. It also automates lateral movement between hosts using discovered credentials, forming a post-exploitation toolkit for moving across networks once access is obtained.
NetExec enables remote command execution on hosts over supported network protocols without interactive logins, and provides credential validation and password spraying against network services such as SMB, SSH, and WinRM to discover valid accounts.
