Facebook Phone Number Security Flaw
Phone numbers on Facebook are not as private as many think, according to Naked Security, a Sophos site. A hole in Facebook's security allows people to type a phone number into the search box to perform a reverse look-up. The results can provide the name of the owner. Altering privacy settings ensure that phone numbers are only visible to the person who owns them. Naked Security takes us through the process of securing the phone number, with suggestions such as always being careful about what is shared.
