# Sera is a free app for mac and iOS that lets you unlock your mac automatically
|
|
# when your iphone is within a configured proximity.
|
|
|
|
# Unfortunately to facilitate this it stores the users login password in their
|
|
# home directory at:
|
|
|
|
# ~/Library/Preferences/no.ignitum.SeraOSX.plist
|
|
|
|
# This makes root privilege escalation trivial and worse than that even
|
|
# facilitates dumping the keychain as we can easily obtain the user's login
|
|
# password. If they are an admin user we can even dump items from the system
|
|
# keychain.
|
|
|
|
# The author of Sera has said he will shut the project down and make the code
|
|
# publicly available so no fix is likely to be forthcoming anytime soon.
|
|
|
|
# It is strongly recommended not to use this app and if you have done so in the
|
|
# past make sure you remove this file that contains your login password.
