Understanding War Dialing and Modems: Techniques and Tools for Network Exploration

War dialing is a method employed to uncover computer systems, networks, or devices linked to the internet or another communication network.

This technique entails dialing a broad range of telephone numbers, often using automated tools or scripts, in order to pinpoint systems that respond with a modem or other networked device.

Following this identification phase, unauthorized activities, such as making unauthorized calls through these devices, may occur. It's worth noting that connecting to the same network is required to execute war dialing.

A modem serves as the intermediary between devices like computers and the internet, utilizing phone lines or cables to convert digital signals to analog for transmission, and vice versa.

One can make calls using numbers that aren't theirs, as demonstrated in tools like WarVOX from. This tool scans all devices with VOIP capabilities to identify those that accept calls, allowing for the capture and utilization of these numbers.
