Deepfakes, an emerging form of manipulated photo and video content, could be the next frontier that businesses have to tackle in cybersecurity. Deepfakes recently have been the subject of entertainment news, such as viral videos of a fake Tom Cruise or a newly trending app that transforms user's photos into lip-syncing videos, but more sophisticated versions could one day pose national security threats, according to experts. The term "deepfakes" is a combination of "deep learning"--a type of artificial intelligence--and "fakes," describing how video and images can be altered with AI to create believable fabrications. The FBI last month warned that attackers "almost certainly" will leverage synthetic content, such as deepfakes, for cyber- and foreign influence attacks in the next 12 to 18 months. There haven't been documented cases of malicious use of deepfakes in healthcare to date, and many of the most popular deepfakes--such as the viral Tom Cruise videos--took weeks of work to create and still have glitches that tip off a close watcher.
