"Online stores run by Apple Inc., Google Inc. and others now offer more than 250,000 applications such as games and financial tools. The apps have been a key selling point for devices like Apple's iPhone. But concerns are growing among security researchers and government officials that efforts to keep out malicious software aren't keeping up with the apps craze.
In one incident, Google pulled dozens of unauthorized mobile-banking apps from its Android Market in December. The apps, priced at $1.50, were made by a developer named "09Droid" and claimed to offer access to accounts at many of the world's banks. Google said it pulled the apps because they violated its trademark policy."
