The New York Times reports:

Federal prosecutors are conducting a criminal investigation into data deals Facebook struck with some of the world’s largest technology companies, intensifying scrutiny of the social media giant’s business practices as it seeks to rebound from a year of scandal and setbacks.

A grand jury in New York has subpoenaed records from at least two prominent makers of smartphones and other devices, according to two people who were familiar with the requests and insisted on anonymity to discuss confidential legal matters. Both companies had entered into partnerships with Facebook, gaining broad access to the personal information of hundreds of millions of its users.

The companies were among more than 150 firms, including Amazon, Apple, Microsoft and Sony, that had cut sharing deals with the world’s dominant social media platform. The agreements, previously reported in The New York Times, let the companies see users’ friends, contact information and other data, sometimes without consent. Facebook has phased out most of the partnerships over the past two years.

“We are cooperating with investigators and take those probes seriously,” a Facebook spokesman said in a statement. “We’ve provided public testimony, answered questions and pledged that we will continue to do so.”

It is not clear when the grand jury inquiry, overseen by prosecutors with the United States attorney’s office for the Eastern District of New York, began or exactly what it is focusing on. Facebook was already facing parallel scrutiny by the Federal Trade Commission and the Securities and Exchange Commission. And the Justice Department’s securities fraud unit began investigating it after reports that Cambridge Analytica, a political consulting firm, had improperly obtained the Facebook data of 87 million people and used it to build tools that helped President Trump’s election campaign.
