Android: Spotify without Ads

Yep! It’s here the first real open source Spotify alternative for Android, I’m not gonna lie, it’s good that we have such option because sometimes adblocking doesn’t prevent the bad guys to get your data or they simply bypass it via https. Remember that ads might be infected! – So now we have something to eat – some Dogfood!

Android: Inject Malware Into Apps Without touching Signatures

The vulnerability CVE-2017-13156 was discovered and reported to Google by security researchers from mobile security firm GuardSquare this summer and has been patched by Google, among other vulnerabilities, as part of its December Android Security Bulletin.

The vulnerability resides in the way Android handles APK installation for some apps, leaving a possibility to add extra bytes of code to an APK file without affecting the application’s signature.

My Android App Collection 2017

I consider the year 2017 to be done. There will be no big announcement anymore, bots are gonna stealing Christmas (like every year) and I’m in general not a big fan of x-mas. So at this point I want to show which apps I used the most this year.

Android Oreo (Go edition) 8.1 – Here is what’s coming!

The Go Edition 8.1 also now scans your entire app collection even while you’re offline or in case you downloaded the app from another Store – this, according to Google shall improve your device security and prevent malware. Critical voices (like mine) might want to warn you about such features because it could be abused by hackers to read-out your app data – but at this time it’s only a theoretically thing since I’m not aware that this was already somehow compromised (yet?) – we btw. are talking about Play Protect.
