Verizon offer under threat after latest Yahoo hack

Yahoo’s latest hack affecting 1bn users has put its $4.83bn acquisition offer from Verizon in jeopardy, according to Bloomberg.

The hack is the second over recent months, pushing the American communications giant to either cut the price on its offer or pull out all together.

On Wednesday Yahoo said it had discovered a new data breach that occurred in August 2013, involving the data associated with more than one billion user accounts.

In September 2014, 500m users were affected and was considered to be one of the world’s largest cyber attacks on a single site.

Verizon told CNBC: "As we've said all along, we will evaluate the situation as Yahoo continues its investigation. We will review the impact of this new development before reaching any final conclusions."

Yahoo’s share price fell 5.3% to 38.74p while Verizon’s shares were up 0.77% at 52.03p at the close on Thursday.
