Some time around August 2013, hackers penetrated the e-mail system of Yahoo, one of the world's largest and oldest providers of free e-mail services. The attackers quietly scooped up the records of more than one billion users, including names, birth dates, phone numbers and passwords that were encrypted with an easily broken form of security.
Yahoo Inc warned on Wednesday that it had uncovered yet another massive cyber attack, saying data from more than 1 billion user accounts was compromised in August 2013, making it the largest breach in history.
Yahoo Inc reported better-than-expected quarterly adjusted profit on Tuesday, a boost for the beleaguered company whose deal to sell its core business to Verizon Communications Inc has been shaken by a massive data breach.
Verizon Communications Inc (VZ.N) said on Thursday it has a "reasonable basis" to believe Yahoo Inc's (YHOO.O) massive data breach of email accounts represents a material impact that could allow Verizon to withdraw from its $4.83 billion deal to buy the technology company.
Yahoo Inc last year secretly built a custom software program to search all of its customers' incoming emails for specific information provided by U.S. intelligence officials, according to people familiar with the matter.
Six senators on Tuesday demanded that Yahoo Inc (YHOO.O) explain why hackers' theft of user information for 500 million accounts two years ago came to light only last week and called the company's handling of the breach "unacceptable."
Democratic Senator Mark Warner on Monday asked the U.S. Securities and Exchange Commission to investigate whether Yahoo (YHOO.O) and its senior executives fulfilled obligations to inform investors and the public about a hacking attack affecting 500 million user accounts.
Yahoo Inc (YHOO.O) said on Thursday that at least 500 million of its accounts were hacked in 2014 by what it believed was a state-sponsored actor, a theft that appeared to be the world's biggest known cyber breach by far.
When senior Yahoo executives gathered for a management retreat in 2006, there was no outward sign of a company in crisis.
Yahoo Inc., once a Silicon Valley legend and Web pioneer, will turn into an investment company with a different name at closing of its deal with Verizon Communications Inc.
On Monday, Yahoo! Inc.’s years-long fight to survive as a standalone company will draw to a close.
