Any time you browse via public wifi you might be being fucked with. How often are you actually? My wager, depending on setting, very rarely.

In your local starbucks? Probably very rarely. In the VIP business lounge of an major international airport? I wouldn't be so sure in this day and age...

In the cafe on the corner of your block in syria, iran and similar places though, the odds are a lot better.
