If you happen to use Apple’s Safari web browser and the auto-fill feature, you’ll want to pay attention to this one as an exploit has surfaced. Recently, a flaw has been identified that allows malicious websites to exploit this feature in order to gain access to a Mac users address book card. Through this, a website can gain access to personal information like the first and last name, email addresses, work place as well as city/state.

Until Apple provides a permanent fix for this bug, the recommended course of action at this time is to disable the “Use info from my Address Book card” feature. This can be done through the Safari browser by selecting preferences, auto-fill, and then just unticking this option.
