The Galaxy S8 was Samsung’s attempt to cover the damage that the Galaxy Note 7 fiasco did. Samsung made a solid entry with the Galaxy S8 that came packed with features. But it turns out that not everything is right with the device, especially with its iris scanner, that is found to be not that secure.
Galaxy S8’s iris scanner comes to rescue when the oddly placed fingerprint scanner of the phone is hard to reach with your index finger. Samsung was really proud of its iris scanner that debuted with the Note 7. It claimed the scanner to be really secure but this video says otherwise.
The people who performed this hack didn’t use any specialised tools to bypass the iris scanner, instead, the things they used are already there around us. They used a camera capable of taking infrared images, which is quite easy to obtain, a laser printer, and contact lenses.
What they did is, first of all, they took a photo of the phone’s owner with that camera and then print that image of the person’s eye using a laser printer. Funny enough, the group got the printout done using a Samsung printer. They had to ensure that the printed photo is of the right size because of the use of contact lens in the next step.
Then, a contact lens is to be placed on the eye’s image to give it a curvature of a real eye. That picture is placed right before a locked Samsung Galaxy S8 and the phone gets unlocked in a split second.
You can watch the group performing the hack in the video below:
Samsung responded to this hack but didn’t completely deny its possibility. A Samsung representative told Forbes, “We are aware of the issue, but we would like to assure our customers that the iris scanning technology in the Galaxy S8 has been developed through rigorous testing to provide a high level of accuracy and prevent attempts to compromise its security, such as images of a person’s iris. If there is a potential vulnerability or the advent of a new method that challenges our efforts to ensure security at any time, we will respond as quickly as possible to resolve the issue.”
