Quest Diagnostics breach exposes data on 11.9 million patients

The House Intelligence Committee has slated a hearing in June that will examine a series of national security matters, including the threat of videos manipulated by artificial intelligence (A.I.) that look strikingly real, a panel aide said.

The congressional hearing on June 13 will be one of the first to primarily focus on so-called “deepfakes,” which experts and lawmakers say pose a major disinformation threat heading into the 2020 election.

The hearing comes amid a spotlight on a fake video of Speaker Nancy Pelosi (D-Calif.) that made its way across Facebook and other social media platforms in late May.

This video, which was viewed millions of times, was edited in a way that made her appear to slur her words. While video was not made with advanced A.I. technology, experts say that will be the next step in the disinformation threat.

The deepfakes technology is growing more sophisticated and prevalent, and average internet users will eventually be able to create doctored videos that will be impossible for the naked eye to distinguish from real ones.
