Google announced on Monday that it would be shutting down its social media platform “Google+” after a massive data breach was discovered. According to Reuters, the breach may affect up to 500,000 users and was most likely caused by a bug that infected the site more than two years ago.

Although the bug was only announced this week, a report from Reuters states that Google knew about the breach as early as March of this year. The company also stated that they had no reason to believe the personal data of any of the effected users was captured or used nefariously.

“None of these thresholds were met in this instance,” Google officials said according to Reuters. “We found no evidence that any developer was aware of this bug, or abusing the API, and we found no evidence that any Profile data was misused.”

According to a report from the Wall Street Journal, Google decided to keep the breach quiet to avoid new regulations and to save the reputation of the brand.
