There's been much controversy over mobile OS security, especially where Android is concerned. With 47 percent of the smartphone market in Q4 of 2011, according to ABI Research, it's no wonder that Android is getting attention.
Its openness fuels adoption by smartphone manufacturers and wireless carriers, aids in mobile innovation, and helps bring more free apps. But some, like those who develop security apps, think its openness also makes it an easier target for malware writers and cybercriminals.

Android malware growth
Depending on where you go, you'll find varying stats on the amount of Android malware we've seen thus far. This is complicated by the fact that most of the information available about malware comes from security vendors, who obviously have a pony in the anti-malware race.
One thing they all agree on is that the amount of malware targeting Android has been growing. For instance, a report from Trend Micro (PDF) includes a chart that shows a large spike in the amount of total Android malware in 2011. Meanwhile, according to NQ Mobile, cases of malware increased from 4,781 cases in 2009 to 10,369 cases in 2010 and 22,600 cases in 2011. And according to Lookout, the likelihood of Americans encountering Android malware went from 1 percent in the beginning of 2011 to 4 percent by year's end.
But the vendors don't always agree. For example, at the end of January, Symantec announced that 13 apps in the Android Market contained malware. Other security vendors disagreed; Symantec later backtracked and said that the code it thought was malware was really from an aggressive ad network.
Meanwhile, Google has reported a 40 percent decrease in the number of potentially malicious downloads from the Android Market from the first to the second half of 2011. (Of course, Google is only accounting for the official Android Market, while the security vendors also scan third-party app markets and websites from around the world.)
