A recent research report suggests that some Apple computers running older operating system software were made vulnerable by a miscommunication that allowed for malicious code to be flagged as fine. The mix-up was apparently caused by third-party whitelisting software. But what is “Whitelisting?”
in a nutshell, it’s the opposite of blacklisting; it allows for access of data, say an email, that might otherwise be blocked. Whereas Gandalf might bellow “You shall not pass!” when something is blacklisted, whitelisting would cause him to smile, scratch his long beard, and say, “Come on in, you may pass!”
If you’ve used software designed to reduce spam emails, you may have already added to a whitelist in order to create set of email addresses that are designated as fine to receive emails from. In the case of the Macs, the development tools were whitelisting code that should have been flagged as dangerous, apparently due to a misunderstanding of some of Apple’s security protocols for Macs.
