One of the basic necessities of today, the WiFi has made things worse, which is the last thing expected from it. A study has revealed that the signal from WiFi is capable of revealing your passwords.
Passwords are probably the most important security feature for any of our accounts and its scary that they can be breached so easily: through your own WiFi signal.Read more ↓
Read on to know all about the newfound glitch in technology. And let’s hope it will be resolved soon.
The Windtalker Method
Researchers from Shanghai Jaio Tong University, the University of Massachusetts at Boston, and the University of South Florida conducted a study which proved that a radio signal can compromise the privacy of your passwords.
Professors from the universities explained how WiFi passwords can be stolen over a common WiFi. For this method to work, it requires the user and the hacker to be connected to the same WiFi. The chances of getting the password right at the first attempt through this method are 81.7%, even on a new device.
This method, called the Windtalker method, does not require any medium between two devices, nor any software installed on the phone of the user.
How Do WiFi Signals Reveal Passwords?
Firstly, hackers carry out parallel scanning of the WiFi signals that emerge from the victim’s device and retrieve the data that has been typed on the device. Hackers are required to identify the signals that arise from the victim’s device.
It is important that the hacker and the victim is connected to the same WiFi. If such a provision is not available, an ad hoc rogue WiFi network is created and offered to users as free WiFi.
Once both the devices are connected to the same WiFi, the finger movements of the user are checked. The directions and pace of the victim’s usage of the keys are traced carefully, and done! The data typed by the victim is out in the open for anyone to access and that rings a couple dozen warning bells for sure.
Do This To Protect Your Passwords!
