Which platform would a typical IT guy be more on guard against?
While Windows has been known for decades to be a hot pot for all PC malware, Android phones are much more ubiquitous and personalized, and (as far as I know) aren’t hardened against malware in any way. I mean, it literally takes just two taps to install a rogue apk and that is notwithstanding that most OEM implementations and apps on the Play Store are ad-ridden privacy nightmares by themselves. At least when it comes to Windows, Administrators have greater control over client machines and can put in restrictions. How would someone handling infosec in an organization control security on people’s personal phones?
But a rogue app can take everything from your phone - your pictures, emails, contacts, docs… without anyone being the wiser since there is no Administrator oversight. On organization Windows systems the user at least requires Administrator permission to run anything that can pose a risk, but he could do the same on Android without anyone stopping him. Dumb people will love to download and install Google_Pay_mod_Unlimited_money.apk that could scoop up all data (including company emails, slack, etc that he is running on his phone) and no one would ever know.
