Prerequisites:

Kali or DragonOS (I prefer DragonOS)

Hack RF One module.

Antenna:

GSM 900 920-960Mhz
5G 3400-3600MHZ
3G 2110 - 2170Mhz
4G 2500 – 2700Mhz
Wi-Fi 2400-2500MHZ

Jammer: Portable jammer with battery, omnidirectional antenna (25m area)

OR

Powerful Jammer for an attack from outside (but requires 220V power supply) (300m area 80W power)

intercept an SMS for 2fa and spoof sim card are more and more complicate with all these new ultra encrypted protocol 3G-4G-5G

The exploit come from the phone, i noticed every phone automatic choose a protocol available for permit communication

If 3-4-5G are not available the phone will automatically connect to a available protocol , here we want to use an old gsm protocol (really vulnerable)

The goal is to downgrade recent operator services (with our jammer) and leave only GSM available

By this way all phone around phone will be automatically connected to the frequencies 800Mhz to 960Mhz

Start jamming fréquencies 5-4-3G and wifi 2400-2600Mhz (depend the operator, some phone can automatically connect to an "operator_auto_login"

With some interception tools you will we able to intercept IMSI and SMS located around you

This is one of the easiest and most fast to learn methods still working
