PacketHound Converts Windows Firewall into Outbound Connection Blocker
Key points
- PacketHound enables 'ask me first' for outgoing connections.
- Users can allow/block connections per app or destination.
- Automatically allows legitimate Windows components.
- Flags tools like PowerShell, curl, and rundll32 for review.
Outbound Connection Control
PacketHound transforms the default behavior of Windows Firewall, shifting its focus to outbound connections. When an application attempts to connect to the internet for the first time, PacketHound presents a prompt to the user. This prompt displays information about the application, its publisher, and the destination of the connection, allowing the user to decide whether to allow or block the connection.
Granular Rule Management
Users can configure rules with specificity, choosing to allow or block connections for an entire application, or for a specific address, host, or domain. These rules can be set to be permanent or temporary, lasting only until the application quits. The tool integrates with the existing Windows Firewall, creating visible rules in wf.msc, ensuring functionality even when PacketHound is not running.
Intelligent System Handling
PacketHound automatically permits connections from legitimate Windows components, reducing unnecessary prompts for system services. It identifies Windows programs based on their location, ownership, and valid Microsoft signatures. However, it specifically flags common tools often exploited by malware, such as PowerShell, curl, certutil, mshta, and rundll32, requiring user approval for their connections despite their Windows origin.
User Interface and Logging
The application provides a user interface to manage rules, allowing users to search, sort, and clear rules for uninstalled programs. Prompts appear without stealing keyboard focus. An activity log records all blocked attempts, including hostname and port, enabling users to review and make decisions on pending connections at a later time.

PacketHound is a new tool that modifies the Windows Firewall to prompt users for permission before applications make outgoing internet connections. It allows users to approve or block connections per application or destination, and automatically permits Windows' own components while flagging common malware tools.
