If they can't access internet, they can't steal my data in the back which is safe right? I wanna try this file encryption app from play store. Before i proceed, i wanna make sure that the app itself is completely safe. It's called SSE encryption app.

  • Give us the link of the app. – Firelord Oct 13 '15 at 2:41
  • play.google.com/store/apps/… – Ygr Oct 13 '15 at 2:45
  • You're misinformed at some part, as I see it. While it is true that if an app hasn't declared network access permissions then it cannot contact its mothership, should it need to, but it is far from considered safe. Tell me, what safeguards do you have to stop such an app from encrypting your data and demand ransom? – Firelord Oct 13 '15 at 2:46
  • How can they encrypt and demand ransom when it can't communicate with the developer? Even if they encrypt the file and demand ransom, as long as the file is encrypted in my local storage, i don't care if it's non accessible, i just don't want some random stranger put hands on it! – Ygr Oct 13 '15 at 2:50
  • That's not hard to do IMO. A cracker needs to be selective during programming of the ransomware. The app can encrypt data, create a string, and ask ransom of some dollars. In instructions, you would be told to enter that string onto a web-portal to receive further instructions to pay ransom. Once you are done paying your money, you would be provided an unlock key which you can put into a corresponding area of the installed app. Ransom complete. Is it hard? I just gave a possible scenario. – Firelord Oct 13 '15 at 2:54

Unfortunately, all apps always have the ability to access the internet. The permission can be misleading. It has to do with viewing other devices on a network and the network details. What you can do is right after downloading the app, put your phone in airplane mode. That will prevent any data from leaving the phone, then uninstall it before turning airplane mode off.

Although in all reality, unless you're running Paranoid Android, your data is never truly safe, and even then it isn't perfect.

  • By "Paranoid Android" are you referring to the famous PA ROM or you literally meant being 'Paranoid'? – Firelord Oct 13 '15 at 2:58
  • What's this "Paranoid android"? Will it be more privacy secured to switch from stock android? – Ygr Oct 13 '15 at 3:08
  • @firelord Meant the ROM. – Ethan Z Oct 13 '15 at 10:39
  • @Ygr paranoid android is a custom ROM that secures your phone FAR better than the stock ROM. However, apps still have the same abilities, so for the context of this question, it wouldn't benefit you much. However, it makes it nearly impossible (note nearly, nothing can be unhackable) for someone to deliberately hack into your phone without your knowledge. – Ethan Z Oct 13 '15 at 10:40
