The question-and-answer website Quora Inc. said Monday that hackers had broken into its network and gained access to data belonging to 100 million users.
Quora detected the hack on Friday and is still investigating the incident. The company said that the hackers gained access to users’ names, email addresses and direct messages.
News of the incident comes three days after Marriott International Inc. reported that hackers had been lurking in its Starwood networks for years, accessing data belonging to up to 500 million travelers. That breach was one of the most severe on record, both by number of people and the type of data that may have been obtained, including passport and credit-card data as well as information on hotel stays.
The Quora episode isn’t as serious, but underlined just how frequent large-scale breaches are becoming.
