I've just stumbled upon this Avast blog post:
http://blog.avast.com/2014/02/06/going-to-the-olympics-prepare-to-be-hacked/It piggybacks on a questionable "investigation" conducted by NBC and tries to scaremonger potential "customers" into using Avast products.
Here's why I say "questionable":
1) There is no disclosure of what actually happened on the Macs
2) We don't know what security settings those computers had. They say they were "out of the box". Did they bother to update those machines before the "experiment"?
3) How was the file on the phone downloaded and how did it actually get to be installed? Side loading is turned off on Android phones by default. This does now prevent files from being downloaded, but it does not auto-install them.
All in all, I would say the NBC piece was a piece of anti-russian propaganda for whatever political reasons. We know for a fact that public wifi is not safer anywhere else, but still... if it's Russia then it has to be "bad". We know, after the Snowden revelations, that the US, UK, Canada and others are spying on their citizens and foreigners... but, if you're in Russia for the Olympics you still should not "expect privacy".
So, why did Avast stoop so low?
