CrowdInspect is a free professional grade tool for Microsoft Windows systems from CrowdStrike aimed to help alert you to the presence of malware that communicates over the network that may exist on your computer. It is a host-based real-time monitoring and recording tool utilizing multiple sources of information to detect untrusted or malicious network-active processes.
Beyond simple network connections, CrowdInspect associates the connection entry with the process that is responsible for that activity. It can display the process name as a simple file name or as as an optional full file path. In addition to the process name, the entry's process ID number, local port, local IP address, remote port, remote IP address and reverse resolved DNS name of the remote IP address is shown. The tool accommodates both IPv4 and IPv6 addresses.
CrowdInspect records details of any entry that is associated with a remote IP address and maintains a chronological list of these accessed by clicking the "Live/History" toolbar button to switch between the regular live netstat window and the history list window.
