xposed偽造收到簡訊

am broadcast -a android.provider.telephony.sms_deliver -n com.android.messaging/.receiver.smsdeliverreceiver  //後面接具體引數
我這裡是先傳送廣播給smsdeliverreceiver 類，因為簡訊最先接收到廣播的就是這個類，然後才會傳送給 receiver.smsreceiver 類。引數有三個：sender、receiver、message，引數名可以自己定義，分別代表傳送人手機號，接收人手機號和簡訊內容。

xposed劫持

finalclass aclass = xposedhelpers.findclass(


"com.android.messaging.receiver.smsreceiver", lpparam.classloader);


xposedbridge.hookallmethods(aclass,"deliversmsintent",newxc_methodhook() catch(exception e) 


string receiver =null;


trycatch(exception e) 


string message =null;


trycatch(exception e) 


pdu = smsutils.createpdusms(sender, receiver, message);//將引數轉換為pdu byte陣列


}catch(exception e) 


intent intent =newintent();


intent.setaction(action);


bundle bundle =newbundle();


byte b =new byte[1][1];


b[0] = pdu;


bundle.putstring("format","3gpp");


bundle.putserializable("pdus", b);


bundle.putstring("slot","0");


bundle.putstring("phone","0");


bundle.putstring("subscription","2");


intent.putextras(bundle);


param.args[1] = intent;


}});

public static byte createpdusms(string sender,string receiver, string body) );


stringtogsm7bitpacked.setaccessible(true);


byte bodybytes = (byte) stringtogsm7bitpacked.invoke(null, body);


bo.write(0x00);// encoding: 0 for default 7bit


bo.write(datebytes);


bo.write(bodybytes);


}catch(exception e) catch(unsupportedencodingexception uex) 


}pdu = bo.tobytearray();


}catch(ioexception e) 


returnpdu;


}private static bytereversebyte(byteb)
private staticstring phonetpye(string phone)


returnphone.length()==11?"+86"+phone:phone;


}
private static byte encodeucs2(string message,byte header)


throwsunsupportedencodingexception 


else


byte ret =new byte[userdata.length+1];


ret[0] = (byte) (userdata.length&0xff);


system.arraycopy(userdata,0, ret,1, userdata.length);


returnret;


}
