ir_sniff¶
Presentation¶
ir_sniff allows to sniff and decode the IR signals captured by an IRMA device. It allows to choose the frequency of the receiver (FREQUENCY parameter, set to 38 kHz by default) and to indicates how many signals have to be captured (NUMBER parameter).

Usage¶
Basic Usage¶
If you want to capture one signal, use the following command :
$ mirage ir_sniff
[INFO] Module ir_sniff loaded !
[PACKET] << IR - NEC Packet | code (32 bits) =76044fc0 >>
[INFO] Mirage process terminated !
If you want to capture multiple signals, you can use the NUMBER parameter in order to provide the number of signal to capture:
$ mirage ir_sniff NUMBER=3
[INFO] Module ir_sniff loaded !
[PACKET] << IR - NEC Packet | code (32 bits) =76044ff0 >>
[PACKET] << IR - NEC Packet | code (32 bits) =76044fd0 >>
[PACKET] << IR - NEC Packet | code (32 bits) =76044fc0 >>
[INFO] Mirage process terminated !
Performing a replay attack¶
This module can be combined with ir_inject in order to perform replay attacks. You can launch this kind of attack by using the following command:
$ mirage "ir_sniff|ir_inject"
[INFO] Module ir_sniff loaded !
[INFO] Module ir_inject loaded !
[PACKET] << IR - NEC Packet | code (32 bits) =76044fc0 >>
[INFO] Injecting ...
[SUCCESS] Injection done !
[INFO] Mirage process terminated !
ir_inject¶
Presentation¶
ir_inject allows to inject IR signals using an IRMA device. It allows to choose the frequency of the transmitter (FREQUENCY parameter, set to 38 kHz by default). You can inject a signal as raw data using the DATA parameter (you have to provide a list of integers), or you can select a specific protocol using the PROTOCOL parameter and provide the CODE and CODE_SIZE parameter, describing the IR code to transmit.

Usage¶
Basic Usage¶
If you want to transmit a raw signal, use the following command :
$ mirage ir_inject DATA=1200,500,5800,1000,500
[INFO] Module ir_inject loaded !
[INFO] Injecting ...
[SUCCESS] Injection done !
[INFO] Mirage process terminated !
If you want to inject a specific code, you have to provide the parameters PROTOCOL, CODE and CODE_SIZE:
$ mirage ir_inject PROTOCOL=NEC CODE=76044FF0 CODE_SIZE=32
[INFO] Module ir_inject loaded !
[INFO] Injecting ...
[SUCCESS] Injection done !
[INFO] Mirage process terminated !
