Android users tend to be from "the third world"? Hardly: many android (and winphone) devices are often the same price or more than the apple equivalents. This doesn't equate with them being used by "poor people".
For some reference statistics, which you will doubtless enjoy manipulating and misreading to give whatever picture you want: smartphone % penetration by country..
Back to your "third world" angle: Here's a breakdown of the US's smartphones by OS. Unless you are going to now state that the USians are in fact living in a third world country, would you care to explain this?
Relating back into the first stats, here's one showing worldwide market share..
While it is interesting to note that the US has a more balanced split of Apple vs Android in it's market, the US is only 13th in overall smartphone penetration. Some "third world" countries such as Spain and Germany have rather higher OS splits in favour of Android compared to Apple.
One point to note is that in the developing markets the price paid for handsets is less than in the developed markets. This necessarily skews the market split away from Apple as other than 2nd hand or older devices, most Apple phones are priced out of the reasonable disposable income price range - food, heating, clothes, education or mobile phone? WinPhone devices are making reasonable inroads into these price constrained markets but nothing compared to feature phones and to a lesser extent "landfill" android phones. It's these phones that will be targetted by this kind of exploit, they are often unsupported, never updated by their manufacturer and often too costly for an end user to even consider the data bandwidth to peform an update and often as a result they have access to local app stores and not Google Play. However this does not mean that an app that requires Root access will work as even the landfill devices don't come with root access as standard.
Basically, it's a security scare story from an advertiser that's sole reason for existing is to sell security products.
