According to WILX-TV 10, Google Plus, the company's failed social network that was meant to rival Facebook, was apparently left vulnerable.

Google says it found a bug that meant the private data of 500,000 users was unprotected.  The Wall Street Journal says the situation went on for three years.

Samuel Burke, a CNN business correspondent said, "this is an error that Google made in its code.  So beginning in 2015, according to the Wall Street Journal report, basically a lot of the personal information that you put on Google Plus or that Google Plus got about you was exposed."
