How the SSID spreads virally.
A second person in close proximity to the user above also has a wireless enabled laptop and is looking to connect to a WiFi network. They scan to see what is available and notice an SSID called “Free Public WiFi”….they connect to it not knowing that it is an ad hoc network. After a few seconds of wondering why they can’t surf the web they disconnect from the SSID, shrug their shoulders and move on with life. Now they have the viral SSID in their preferred list too. The next time they power on their laptop it starts to look for the “Free Public WiFi” SSID. This process is repeated in many locations across the US and world again and again. Soon this SSID is in preferred wireless networks lists everywhere spreads like a virus.
What is MAC ?
In Computer Networking, a Media Access Control address (MAC address) or Ethernet Hardware Address (EHA), hardware address, adapter address or physical address is a quasi-unique identifier assigned to most network adapters or network interface cards (NICs) by the manufacturer for identification.
