Data breach

On my Tech Tent podcast this week, we look at the promise and perils of data and ask whether we are ready to share more of it with companies that say they will use it for our benefit.

Google: Good for your health?

This week, we heard of a massive data partnership between a technology company and the Britain's National Health Service. The idea is that London's Royal Free Hospital will share data from two and a half million patients with DeepMind - Google's artificial intelligence business.

The breach came after the laptop of an employee at Hewlett Packard Enterprise working on a naval contract was "compromised", the Navy said.

It added that "unknown individuals" accessed the sensitive information on current and former sailors.

The data included names and social security numbers, but the Navy does not currently believe it was misused.

The data included email addresses and passwords that had been stored without any protection, a security firm said.

Leaked Source said the massive cache of credentials dated from 2012 but had only now been leaked and put online.

And it had come from a hacker who had supplied security firms with 43 million user names from music service Last.fm.

Rambler has been described as the Russian equivalent of Yahoo as it offers email services as well as acting as a news and content hub for its users.

"We know about that database," said the service in a statement.

Katherine Archuleta, director of the federal Office of Personnel Management, submitted her resignation to President Barack Obama on Friday morning, the White House said. She'll be replaced on a temporary basis by the agency's deputy director, Beth Cobert, who will step into the role on Saturday.

Less than 24 hours earlier, Archuleta had rebuffed demands that she resign, telling reporters she had no intention of leaving and that her agency was doing everything it could to address concerns about the safety of data in its hands.
