Public spaces are definitely not the best places to use passwords or deal with sensitive information. To add to the risks of shoulder surfing, CCTV and dodgy wifi, we now have keyboard eavesdropping.

[…] Cybersecurity experts from Southern Methodist University in Texas found that sound waves produced when we type on a computer keyboard can successfully be picked up by a smartphone.
The acoustic signals intercepted by the phone can then be processed, allowing a skilled hacker to decipher which keys were struck and what they were typing.
The researchers were able to decode much of what was being typed using common keyboards and smartphones – even in a noisy conference room where others were typing and talking.
Study co-author Professor Eric Larson said: “We were able to pick up what people are typing at a 41 percent word accuracy rate. And we can extend that out – above 41 percent – if we look at, say, the top 10 words of what we think it might be.”
