Trial of Former Uber Executive Has Security Officials Worried About Liability for Hacks

Joseph Sullivan, the former executive, is facing criminal obstruction charges in a trial that began Wednesday in San Francisco for his role in paying hackers who claimed to have discovered a security vulnerability within Uber’s systems.
