I have been using an older 3g card. (Virgin Mobile Novatel MC760 Broadband2Go USB)
I use it with my Wi-Fi pineapple and other various things. It is just a pay as you go kind of
deal so you can use cash and stay somewhat anonymous. I have not topped up this
3g card for a few months though.
I am running Kali linux and connect the card with either wvdail or network-manager.
Once the card is connected and you open a browser, you can get to google, run
a search, but then you are locked out and have to login to topup your data plan.
The fact that you can get that far before you are locked out got me thinking...
what else can I do? I tried to ping 8.8.8.8, and nothing happened. I tried
wget, angain nothing happened. Then just for shits I tried an nmap scan, and
it totally works!!
For some reason I can run nmap scans with a 3g card I have not
payed for in months. I ran several namp scans and it just keeps on working.
I would like to know if others can replicate this result.
I would also like to know if anyone has an idea of why this is working and what
other way we can have some fun with it.
