Update Your iPhone Before Hackers Steal Your Data

Apple's security patch fixes a major bug affecting millions of iOS devices and Macs

The security hole allowed hackers to spy on your unencrypted data ranging from bank information to personal emails.

If you’re using an iPhone or Mac running OS X Mavericks, immediately run a software update. Apple’s iOS and OS X platforms received updates on Friday and Tuesday, respectively, fixing a security hole that left millions vulnerable to hackers after sensitive personal information.

The issue was in the way Apple handled securely transmitting data over the Internet using SSL. SSL (Secure Sockets Layer) and TSL (Transport Layer Security) are both cryptography protocols that protect information like usernames and passwords and prevent hackers from spying on your browser’s activity.

When viewing banking or email accounts you may see a lock in your browser’s URL bar, indicating your data is private and protected by these encryption systems.

The security hole allowed hackers on the same Wi-Fi network to potentially view unencrypted data and personal information. The flaw originates from a faulty line of code in Apple’s SecureTransport method of verifying the legitimacy of a site’s SSL certificate.

On Friday a patch was released for iOS devices, fixing the security hole affecting millions of users, but was still present on Apple’s OS X-powered machines running Mavericks, the company’s latest operating system.

Researcher Ashkan Soltani discovered the bug affected any Mac app that used the SecureTransport security protocol, including Twitter and Apple’s Mail app. “For example, when your Calendar or Mail.app synced to Gmail,” Soltani wrote, “those communications were vulnerable to eavesdroppers on the network as a result of this error.”

Ashkan Soltani tweeted a list of a half dozen Mac apps affected by the security flaw.
