Android hack, Twitter to report and New York's 'new' airport

It's green arrows across the board for U.S. stocks today (^DJI, ^GSPC, ^IXIC).

Here are some of the other stories Yahoo Finance is keeping an eye on today.

Android hack
A major mobile security flaw could impact up to 950 million Android users around the globe. It has to do with the way the operating system processes pictures, audio or video sent via text message. The worst case scenario would allow hackers full access to your phone. The flaw was found by a cyber security company called Zimperium and they notified Google (GOOGL) on April 9th and told them how to fix it. Here we are on July 28th and it would seem no such fix has been widely implemented.

Twitter to report
Twitter's (TWTR) interim CEO Jack Dorsey will make his first appearance on an earnings call for the company he helped found after the bell today. Twitter is down more than 25% in the last year and as the company searches for a permanent CEO the rumor mill is rife with takeover talk. What is the way forward for the social media network?

New retirement savings data
Are you saving up enough for retirement? Most Americans aren't and leaving a total of $24 billion on the table certainly isn't helping. New data from Hearts and Wallets, a financial research firm, says Americans aren't taking enough advantage of their employer-backed retirement  programs. Household savings in employer sponsored plans dropped from 29% in 2013 to 22% in 2014. Only 56% of those eligible for the plans took part in them at all in 2014, down from 60% the prior year.
