SAN FRANCISCO (REUTERS) - Yahoo will disclose details this week of a data breach that compromised the data of several hundred million users, technology news site Recode reported on Thursday (Sept 22) , citing unnamed sources familiar with the company's plan.
Reuters was not able to immediately confirm the report.
It was not clear how such a disclosure might affect Yahoo's plan to sell its email service and other core internet properties to Verizon Communications Inc for US$4.8 billion (S$6.52 billion).
Yahoo might have to force users to reset their passwords, the Recode report said, citing unnamed sources.
The report follows an Aug 1 story in the technology news site, Motherboard, that said a cyber criminal known as Peace was selling the data of about 200 million Yahoo users, but did not confirm its authenticity. The Motherboard report was published a week after Verizon announced its deal with Yahoo.
Peace was selling that batch of data on the 200 million Yahoo users for 3 bitcoin, or around US$1,860, according to Motherboard. The possibly compromised data includes user names, birth dates, some backup email addresses and scrambled passwords, Motherboard said.
