Yahoo’s competence in handling the aftermath of the theft of personal information of at least 500 million accounts has been heavily criticised by US senators.
The security breach happened back in 2014 and saw the theft of 500 million accounts. But the hack only came to light last week.
Millions of Sky and BT broadband customers could be affected, as BT had used Yahoo Mail for its email service until 2013. Sky meanwhile still uses Yahoo for its email service.
Six Democratic US senators wrote a letter to Yahoo CEO all Marissa Mayer, demanding an explanation as to why it took two years for the hack to come to light. They called the company’s handling of the breach “unacceptable”, according to Reuters.
“That means millions of Americans’ data may have been compromised for two years,” the senators reported wrote. “This is unacceptable.”
They have also asked Yahoo to provide them with information of Yahoo’s investigation into the hack, how it is co-operating with authorities, and what plans it has to protect affected users. They also want to know what steps Yahoo is taking and for a timeline of the hack and its discovery.
A Yahoo spokesman meanwhile reportedly said the firm would respond in a “timely and appropriate manner” to the letter.
Meanwhile the US securities watchdog Securities and Exchange Commission has reportedly warned companies to promptly disclose “cyber events”.
Earlier this week cybersecurity specialist Venafi warned that despite the hack occurring two years ago, Yahoo had still not implemented strong digital certificates.
They also warned that Yahoo is still using cryptography (MD5) that has been known to be vulnerable for many years now.
The core assets of Yahoo are in the middle of the process of being acquired by Verizon for $4.83 billion (£3.86bn).
