No blog da empresa Avast foram publicados<\/a><\/noindex> Resultados do estudo das permiss\u00f5es solicitadas pelos aplicativos listados no cat\u00e1logo do Google Play que implementam lanternas para a plataforma Android. No total, foram encontrados 937 lanternas no cat\u00e1logo, das quais sete apresentaram elementos de atividade maliciosa ou indesejada, enquanto as demais podem ser consideradas 'limpas'. 408 aplicativos solicitaram 10 ou menos permiss\u00f5es, enquanto 262 aplicativos exigiram consentimento para fornecer 50 ou mais permiss\u00f5es. <\/p>\n

10 aplicativos solicitaram entre 68 e 77 permiss\u00f5es, sendo que quatro deles foram baixados mais de um milh\u00e3o de vezes, dois cerca de 500 mil vezes e quatro cerca de 100 mil vezes.<\/p>\n

Ao analisar quais permiss\u00f5es os aplicativos com funcionalidade declarada de lanterna (n\u00e3o lanterna como fun\u00e7\u00e3o auxiliar, mas aplicativos que em sua maioria se posicionam apenas como lanterna) solicitaram, foi identificado que 77 aplicativos pedem fun\u00e7\u00f5es de grava\u00e7\u00e3o de \u00e1udio, 180 exigem leitura de dados da agenda de contatos, 21 \u2014 acesso para grava\u00e7\u00e3o na agenda de contatos, 180 \u2014 possibilidade de realizar chamadas, 131 \u2014 acesso \u00e0 localiza\u00e7\u00e3o precisa, 63 \u2014 atender chamadas, 92 \u2014 fazer chamadas, 82 \u2014 receber SMS, 24 \u2014 carregar dados sem notifica\u00e7\u00e3o. <\/p>\n

282 programas exigem acesso \u00e0 fun\u00e7\u00e3o de encerramento for\u00e7ado de processos em segundo plano (presumidamente, esta capacidade \u00e9 utilizada para encerrar processos e reduzir o consumo de energia). Na realidade, para o funcionamento da lanterna, \u00e9 necess\u00e1rio apenas acesso ao LED do flash da c\u00e2mera e, opcionalmente, a capacidade de bloquear a transi\u00e7\u00e3o do dispositivo para o modo de espera.<\/p>\n

\"Avalia\u00e7\u00e3o<\/a><\/noindex><\/center><\/p>\n

Como exemplo, foi analisado um aplicativo t\u00edpico de lanterna, que declara apenas a fun\u00e7\u00e3o de lanterna e informa que o aplicativo n\u00e3o requer permiss\u00f5es adicionais. No entanto, o programa solicita 61 permiss\u00f5es, entre as quais a capacidade de fazer chamadas, ler a agenda telef\u00f4nica, determinar a localiza\u00e7\u00e3o, usar Bluetooth, gerenciar o estado da conex\u00e3o de rede, obter uma lista de aplicativos instalados, ler e gravar no armazenamento externo.<\/p>\n
