The massive data breach at Yahoo that compromised as many as one billion users may have Verizon Communications (VZ) rethinking its plans to acquire the Sunnyvale, California-based tech giant.
Verizon said in July it would acquire Yahoo for $4.8 billion, a year after purchasing AOL for $4.4 billion in a bid to broaden the communications company’s internet business. Yahoo said in a statement Wednesday that it has “taken steps to secure user accounts and is closely working with law enforcement.”
The unidentified hackers in August 2013 stole names, e-mail addresses, telephone numbers, dates of birth, passwords and in some cases security questions and answers, Yahoo said. The stolen data doesn’t include passwords in clear text, payment data or bank account information, the company said. Yahoo said a third party accessed proprietary code to forge cookies, and has linked some of the breach activity to the same hackers responsible for data theft the company disclosed on Sept. 22.
