Vietnamese security company Bkav made headlines in mid-November after uploading a video featuring Face ID accessed by a mask, but there were several questions about the unlocking methods used in the video, including whether "Require Attention" was turned on. Now, Bkav has shared a second video with a new mask and a clearer look at how the mask was used to spoof Face ID. Bkav claims the materials and tools used to create the mask are "casual for anyone" and that Face ID is "not secure enough to be used in business transactions," but it's worth noting that fooling Face ID in this way requires a 3D printer, several hundred dollars' worth of materials, physical access to a person's iPhone X, and detailed facial photographs that can be used to reconstruct a person's face. Even then, if the 3D printed mask and the design of the infrared eyes aren't perfect, Face ID will fail after five attempts.
