GoPro (NASDAQ: GPRO), the popular portable video camera, is plunging again, according to Business Insider. Since Monday, the stock sunk about 5 percent, a trend continuing over the past few months. Chinese competitor Xiaomi released a similar 16 megapixel unit and may contribute to GoPro’s recent decline, Business Insider reported. However, analysts believe GoPro will lead this industry for years to come, despite large competitors. This stock decline comes in the wake of safety and security concerns about GoPro’s WiFi capabilities, The Register reported. "I wrote a small python script that runs on a range of the URLs, extracts the settings from the response and puts them into a csv file,” security researcher Ilya Chernyakov said. "There were no complications, nor noticeable shape limiting for downloading so I was able to create a list of 1000 Wi-Fi names and passwords, including my own." The Register commenter Vince H said: "Follow the link to Chernyakov's actual post on the subject - it makes it a lot clearer. “It looks like the Go Pro cameras offer their own WiFi so that they can be controlled from a smartphone app when out and about. Chernyakov borrowed a friends camera, but his friend didn't know the WiFi settings, so he followed the procedure for "resetting" the WiFi settings, which resulted in a file download from a URL including a numeric token. From what he said, the zip file is supposed to be put on an SD card and put in the camera; rebooting the camera then causes the WiFi to be reset. However, Chernyakov opened the zip file, and found a file inside that contained the camera's WiFi settings (probably taken from the smartphone app, which sends the info 'home' - i.e. the reset procedure involves making the camera match the app). He therefore guessed changing the token in the URL would result in him downloading other people's Go Pro [app and therefore camera] wireless settings; testing that theory proved it to be correct.”
