In Android, we have the concept of permissions, users feel confident that only if they turn on the permission, their data is shared. But what about an app silently sitting on your device with no permission whatsoever! What can that app know about you?\n\nIn this talk, I'll talk about the Privacy Posture of Android!\nWhat kind of data is being collected, and how is it channelled and used? How does advertising work on mobile?\nCan your device be fingerprinted? What kind of privacy threats exists on Android?\nWe will learn about the permission model of Android and how permissions operate at the kernel level!\nThis shall be followed by a demo of an Android app, which needs no permission from the user. We will see what all information can be retrieved from your device, without any permission!","original_language":"eng","persons":["Aditi Bhatnagar"],"tags":["mch2022","90","2022","MCH2022 Curated content"],"view_count":208,"promoted":false,"date":"2022-07-26T14:00:00.000+02:00","release_date":"2022-07-26T00:00:00.000+02:00","updated_at":"2026-02-18T06:00:03.262+01:00","length":1815,"duration":1815,"thumb_url":"https://static.media.ccc.de/media/events/MCH2022/90-689c913c-4a9b-5afe-9c00-ceab1af64a54.jpg","poster_url":"https://static.media.ccc.de/media/events/MCH2022/90-689c913c-4a9b-5afe-9c00-ceab1af64a54_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/MCH2022/90-689c913c-4a9b-5afe-9c00-ceab1af64a54.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/MCH2022/90-689c913c-4a9b-5afe-9c00-ceab1af64a54.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/mch2022-90-no-permissions-needed-","url":"https://api.media.ccc.de/public/events/689c913c-4a9b-5afe-9c00-ceab1af64a54","conference_title":"May Contain Hackers 2022","conference_url":"https://api.media.ccc.de/public/conferences/MCH2022","related":[],"recordings":[{"size":153,"length":1814,"mime_type":"video/webm","language":"eng","filename":"mch2022-90-eng-No_Permissions_Needed_webm-hd.webm","state":"new","folder":"webm-hd","high_quality":true,"width":1920,"height":1080,"updated_at":"2022-07-27T16:20:08.866+02:00","recording_url":"https://cdn.media.ccc.de/events/MCH2022/webm-hd/mch2022-90-eng-No_Permissions_Needed_webm-hd.webm","url":"https://api.media.ccc.de/public/recordings/60790","event_url":"https://api.media.ccc.de/public/events/689c913c-4a9b-5afe-9c00-ceab1af64a54","conference_url":"https://api.media.ccc.de/public/conferences/MCH2022"},{"size":69,"length":1814,"mime_type":"video/webm","language":"eng","filename":"mch2022-90-eng-No_Permissions_Needed_webm-sd.webm","state":"new","folder":"webm-sd","high_quality":false,"width":720,"height":576,"updated_at":"2022-07-27T15:22:05.236+02:00","recording_url":"https://cdn.media.ccc.de/events/MCH2022/webm-sd/mch2022-90-eng-No_Permissions_Needed_webm-sd.webm","url":"https://api.media.ccc.de/public/recordings/60784","event_url":"https://api.media.ccc.de/public/events/689c913c-4a9b-5afe-9c00-ceab1af64a54","conference_url":"https://api.media.ccc.de/public/conferences/MCH2022"},{"size":27,"length":1815,"mime_type":"audio/mpeg","language":"eng","filename":"mch2022-90-eng-No_Permissions_Needed_mp3.mp3","state":"new","folder":"mp3","high_quality":false,"width":0,"height":0,"updated_at":"2022-07-26T23:23:03.910+02:00","recording_url":"https://cdn.media.ccc.de/events/MCH2022/mp3/mch2022-90-eng-No_Permissions_Needed_mp3.mp3","url":"https://api.media.ccc.de/public/recordings/60714","event_url":"https://api.media.ccc.de/public/events/689c913c-4a9b-5afe-9c00-ceab1af64a54","conference_url":"https://api.media.ccc.de/public/conferences/MCH2022"},{"size":62,"length":1814,"mime_type":"video/mp4","language":"eng","filename":"mch2022-90-eng-No_Permissions_Needed_sd.mp4","state":"new","folder":"h264-sd","high_quality":false,"width":720,"height":576,"updated_at":"2022-07-26T23:22:05.372+02:00","recording_url":"https://cdn.media.ccc.de/events/MCH2022/h264-sd/mch2022-90-eng-No_Permissions_Needed_sd.mp4","url":"https://api.media.ccc.de/public/recordings/60713","event_url":"https://api.media.ccc.de/public/events/689c913c-4a9b-5afe-9c00-ceab1af64a54","conference_url":"https://api.media.ccc.de/public/conferences/MCH2022"},{"size":21,"length":1814,"mime_type":"audio/opus","language":"eng","filename":"mch2022-90-eng-No_Permissions_Needed_opus.opus","state":"new","folder":"opus","high_quality":false,"width":0,"height":0,"updated_at":"2022-07-26T23:20:03.673+02:00","recording_url":"https://cdn.media.ccc.de/events/MCH2022/opus/mch2022-90-eng-No_Permissions_Needed_opus.opus","url":"https://api.media.ccc.de/public/recordings/60711","event_url":"https://api.media.ccc.de/public/events/689c913c-4a9b-5afe-9c00-ceab1af64a54","conference_url":"https://api.media.ccc.de/public/conferences/MCH2022"},{"size":179,"length":1814,"mime_type":"video/mp4","language":"eng","filename":"mch2022-90-eng-No_Permissions_Needed_hd.mp4","state":"new","folder":"h264-hd","high_quality":true,"width":1920,"height":1080,"updated_at":"2022-07-26T17:32:04.440+02:00","recording_url":"https://cdn.media.ccc.de/events/MCH2022/h264-hd/mch2022-90-eng-No_Permissions_Needed_hd.mp4","url":"https://api.media.ccc.de/public/recordings/60582","event_url":"https://api.media.ccc.de/public/events/689c913c-4a9b-5afe-9c00-ceab1af64a54","conference_url":"https://api.media.ccc.de/public/conferences/MCH2022"}]}
