      This lib is located in /system/lib/libdoor.so or /system/lib64/libdoor.so. You can find the sample here: https://www.virustotal.com/#/file/3e6df251ad4fe115563b51b302fec2d7836e14dd28ae06e8b41c1939d4bca33d …

      This is the interesting strings of the lib. After a first read we can see that libcrypto is used and the key and the password are backup in /data/backup/fpwd and /data/backup/fkeypic.twitter.com/Y0JbAk3Fp7

      This is the code responsible of the password verification. 1st it check the length, calculate the hash and compare it to the correct one.pic.twitter.com/efldDJO0Qu

          I'm sorry, but I'm asking for a refund. This is too much. Root access to my phone ? My fingerprint, my credit cards, my personal data is more important.

          you should be asking for compensation ;-) but as a world we live in, we are not there yet. User Privacy is being abused on a Minute base, if not every second :|

          Maybe we can finally get a security update for our phones, which also includes all the other fixes for critical issues since the last one (which for my X is over a year old)?

          When is the fix rolling out? Also, please remove that 100+MiB logging app that "should" be disabled. There's no point on having it.
