Further is a\r\nbank logo added to the specific Android app to trick users into thinking this is a legitimate app. Moreover, if the\r\nvictim is not a real victim, the link to download the APK is not the malicious APK, but the real 'Signal Private\r\nMessenger' tool, hence the victim's phone doesn't get infected.\r\nReferences\r\n2017-08-03 ⋅ GovCERT.ch ⋅ GovCERT.ch\r\nThe Retefe Saga\r\nRetefe Dok Retefe\r\n2017-02-24 ⋅ Some stuff about security..
