tokens: Let ’ s compare examples of traffic from Smaps and Asacub — an initializing request to the C & C server with information about the infected device and a response from the server with a command for execution : Smaps request Asacub request Decrypted data from Asacub traffic : { “ id ” : ” 532bf15a-b784-47e5-92fa-72198a2929f5″ , ” type ” : ” get ” , ” info ” : ” imei:365548770159066 , country : PL , cell : Tele2 , android:4.2.2 , model : GT-N5100 , phonenumber : +486679225120 , sim:6337076348906359089f , app : null , ver:5.0.2″ } Data sent to the server [ { “ command ” : ” sent & & & ” , ” params ” : { “ to ” : ” +79262000900″ , ” body ” : ” \u0410\u0412\u0422\u041e\u041f\u041b\u0410\u0422\u0415\u0416 1000 50″ , ” timestamp ” : ” 1452272572″ } } , { “ command ” : ” sent & & & ” , ” params ” : { “ to ” : ” +79262000900″ , ” body ” : ” BALANCE ” , ” timestamp ” : ” 1452272573″ } } ] Instructions received from the server A comparison can also be made of the format in which Asacub and Smaps forward incoming SMS ( encoded with the base64 algorithm ) from the device to the C & C server : Smaps format Asacub format Decrypted data from Asacub traffic : { “ data ” : ” 2015:10:14_02:41:15″ , ” id ” : ” 532bf15a-b784-47e5-92fa-72198a2929f5″ , ” text ” : ” SSB0aG91Z2h0IHdlIGdvdCBwYXN0IHRoaXMhISBJJ20gbm90IGh1bmdyeSBhbmQgbmU= ” , ” number ” : ” 1790″ , ” type ” : ” load ” } Propagation The banking Trojan is propagated via phishing SMS containing a link and an offer to view a photo or MMS .
