The leak includes personal information on 533 million Facebook users, such as phone numbers, Facebook IDs, full names, locations, birth dates, bios and in some cases email addresses, Business Insider reported.

At the time, the company addressed a flaw in its technology that allowed the information to leak out. However, once such data escapes from Facebook’s network, the company has limited power to stop it from spreading online.

The report comes amid a global chip shortage that started with overbooked factories in Taiwan late last year, but has since been exacerbated by a fire at a plant in Japan, a freeze that knocked out electricity in the U.S. state of Texas and a worsening drought in Taiwan this year. The shortage has idled some production lines at automobile factories in the United States, Europe and Asia.

“Our aim is to ensure that control systems serving 50,000 or more Americans have the core technology to detect and block malicious cyber activity,” Anne Neuberger, deputy national security adviserShe said the administration has identified five specific modernization efforts as a result of its review of how the SolarWinds hack happened, including using technology that continuously monitors for malicious activity and requiring greater use of multi-factor authentication so systems can’t be accessed with a stolen password alone.

That threat to critical infrastructure was laid bare in February after a hacker’s botched attempt to poison the water supply of a small Florida city raised alarms about how vulnerable the nation’s utilities may be to attacks by more sophisticated intruders.
