      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

          The best thing in this story is the password. It's angela (see the reference?). This backdoor is here intentionally. When the fiction become a reality. Good luck @getpeid, you will need a very good explanation. cc @whoismrrobotpic.twitter.com/IJgsu6hCEc

          Once again this app is a system app made by @Qualcomm. So possibly a lot of @Qualcomm based phones are affected. Can you open Settings -> Apps -> Menu -> Show system apps and search EngineerMode in the list to check? If you find the app reply to this tweet with your device model

          Potentially, however the bulk of the change needs to be from within those orgs. We (many sec folks) have been fighting this fight for a long time, OEMs tend to not care

          Folks need to vote with their wallets if they care about security. If you want to see an OEM who screws up constantly, look at the ADUPs/BLU/Mediatek junk - very similar (if not worse)
