https://techcrunch.com/2017/09/08/equifaxs-stock-is-plummeting-after-it-reported-a-massive-security-breach/ >Shares of credit reporting service Equifax are collapsing — down more than 13% — in the morning trading hours after the company reported a security breach yesterday that could involve 143 million customers. >That breach included sensitive data like social security numbers, date of birth, addresses, and potentially drivers license numbers. All in all, this is a gold mine of information for potential fraud or identity theft. Equifax said that it discovered the leak on July 29th this year. In all, it’s going to be an expensive process that may include a lot of things well beyond the initial impact crater and investigation, like offering credit monitoring services.
