Hong Kong - Yahoo! is preparing to disclose a “massive” data breach of its main service, Recode reported, just as Verizon Communications prepares to take over the ailing internet company’s core assets.
The break-in was “widespread and serious” and is expected to be disclosed this week, the tech news website said, citing several anonymous sources close to the situation as saying.
Yahoo didn’t respond to phone and e-mailed requests for comment outside of normal business hours.
Such a revelation would confirm earlier reports that the same hacker who’d stolen data from LinkedIn was now selling information from 200 million Yahoo accounts on a dark web marketplace.
The company said that it appeared more data was taken in the initial compromise and that the company was just learning about the larger amount through the hacker’s posting.
Like many Internet companies that have been breached, LinkedIn only reset passwords of everyone it believed was part of the breach at the earlier time, which amounted to 6.5 million users.
