Η pandemic Coronavirus pushes more and more people to work from home, via computer, which in turn has increased the risks for safety of personal information by hackers. There are many employees who use video calling platforms such as Zoom, Microsoft Teams, Google Meet and others.
And maybe the companies behind these platforms have enhanced the security they offer to users However, according to a study by the University of Texas and the University of Oklahoma, hackers use a new method based on tiny visuals and an algorithm to guess a user's password if logged in to an account while on a video call.
According to Forbes, a malicious agent can use a methodology called keystroke inference. Basically what they do is monitor users' shoulders and upper arms when a video call, to gather information about what they are typing.
Although the movements are small and imperceptible, a hacker could guess quite accurately password of an atom, with the help of an algorithm.
The software you use to guess passwords based on these tiny visuals correctly calculates a password by 75% if the password is included in the Reference Database containing used passwords.
However, the strongest passwords, such as random ones or really unique phrases, were more difficult to detect by the algorithm, as only 18,9% of the total passwords were calculated correctly and 74% of the passwords that were not in the reference database, resisted this intrusion method.
As of course in all cases you want to protect one account, there are some practices you can follow that are particularly effective:
- Change the default password
- Do not use the same password for multiple accounts
- Change your password regularly
- Enable multi-factor authentication
