The markets look set for a pullback this morning, one day after a post-election stock surge that drove the S&P 500 index, the Dow Industrials and other stock indexes to record highs. Today, we’ll see earnings from a few big food brands, and later from the media and entertainment giant Disney (we’ll be listening in for Frozen references). Plus, Mark Zuckerberg is taking your questions on Facebook.

Here’s what else you need to know about in business news today.

1. Protect your iPhone!

There’s a new threat to your Apple (AAPL) gadget, reports Fortune’s Philip Elmer-DeWitt, and it’s originating in China. The bug, called WireLurker, has only appeared in China thus far, with Apple looking to stop it from spreading. The malware can infiltrate any device, even non-jailbroken ones, through computer cables.

2. The ride-sharing wars go on

Uber vs. Lyft is one of the more fascinating start-up wars of the past few years, and the latest chapter seems no different. According to Bloomberg, Lyft is suing its former COO Travis VanderZanden, who recently left to join for Uber. Lyft claims he took proprietary data about Lyft’s plans to expand overseas.

3. Have a burger and a beer

Two major food companies are reporting earnings this morning — burger chain Wendy’s and brewer Miller Coors. The beer company reported higher sales. Hamburger chain Wendy’s posted revenue for its quarter that missed Wall Street’s forecasts.

4. Earnings never bothered me anyway

Also reporting today? Disney. The Mouse House is widely expected to post boffo results, still driven by the mega success of last year’s hit movie Frozen. Costumes, merchandise and DVD sales really start to add up — a fact to which many parents’ can surely agree.

5. A chat with Zuck

If you have a question for Facebook(FB) founder Mark Zuckerberg, get ready, because the man behind your mom’s favorite social network is talking. The session is live today at 5 p.m. ET.
