If Your Holiday Gift Was a Tech Device, It's Time to Change the Password

Whatever consumer electronics product you can name, there’s probably a “smart” version that you configure via an app or Internet-connected interface once you’ve connected it to your Wi-Fi network. For ease of setup and to keep costs down, many such devices come pre-configured with not just a default username and password, but the same default username and password as all other units. That’s bad enough, but worse, most people never change those defaults, which is just asking hackers and malicious bots to break in and take over. This risk is...

Apple makes it easy to move data between Macs.

LastPass Security Breach. Here's What to Do

Password management company LastPass has announced that it suffered a security breach in which attackers stole both encrypted customer account data (which is bad) and customer vaults containing encrypted usernames and passwords (which is much, much worse). On the positive side, the data of users who abided by LastPass’s defaults and created master passwords of at least 12 characters in length will likely resist cracking attempts.

What Is Advanced Data Protection for iCloud? Should You Enable It?

In early December, Apple made a surprise announcement: Advanced Data Protection for iCloud. It’s not as though iCloud’s standard data protection is problematic, but it hinges on one architectural decision that makes some iCloud data theoretically vulnerable: Apple holds the encryption keys necessary to decrypt iCloud data. Because Apple controls those encryption keys, an attacker or rogue Apple employee who could gain access to them could theoretically steal iCloud data. (There are many more safeguards; it’s not like there’s a big printout of keys anywhere.) Plus, since Apple has the...
