Over 20% of commuting Americans say strangers peek at their devices in public

A significant number of smartphone users involuntarily expose themselves to the so-called “shoulder surfing” phenomenon.

As many as 75% of Americans use smartphones while traveling to work. While commuting, 63% listen to music or podcasts, 51% call and message people, and 43% scroll social media, a survey by cybersecurity company Nord Security survey has revealed.

When using their devices, Americans often expose themselves to the so-called shoulder surfing phenomenon, when strangers peek at other people's screens in public places, such as buses, trains, or subways.

According to the survey, 23% of commuting Americans claim to have witnessed someone looking at their device during a trip.

“Most people think of cyber threats as something happening online, but sometimes, the risk is standing right next to you. A quick glance from the wrong person can reveal passwords, financial details, or private messages, putting your personal data at risk," says Adrianus Warmenhoven, a cybersecurity expert at NordVPN.

Up to 75% of US commuters use their mobile phone during a trip, the most popular digital device choice far ahead of laptops (17%), tablets or iPads (17%), portable gaming consoles (8%), or other items.

The survey also revealed that one-third of American commuters who go online during their travels rely on public WiFi, exposing themselves to potential cyber threats. Nord Security notes that 13% of those surveyed take no measures to protect their data.

“Public WiFi is a hacker's playground. Avoid accessing sensitive accounts on these networks, always enable two-factor authentication, and keep your devices updated to stay one step ahead of cyber threats,” Warmenhoven recommends.

The survey was commissioned by NordVPN and conducted by the external companies Cint and Norstat on February 20th-March 2nd, 2025.
