Detecting anomaly and fake is the foremost killer application of AI. Given enough 'ground truth' data with enough details and dimensions, AI algorithms should be able to spot anomaly or fake much better than any human and it can be easily scalable unlike human.

Ironically, however, the thing that make AI popular to the mass is deepfake. For this purpose, AI is then being used recursively to accurately create and detect deepfake in a useless vicious cycle.
