It is so funny that four years later, Yahoo still doesn’t know how 3 billion accounts were hacked. – When she was pressed by the Senate Commerce Committee in a security hearing about how Yahoo failed to recognize that 3 billion accounts were compromised, former Yahoo CEO, Marissa Mayer, admitted that the specifics of the attack still remain unknown.
She said: “To this day we have not been able to identify the intrusion that led to this theft. “…We don’t exactly understand how the act was perpetrated. That certainly led to some of the areas where we had gaps of information.”
Mayer said in her testimony that “Yahoo worked closely with law enforcement, including the Federal Bureau of Investigation, who were ultimately able to identify and expose the hackers responsible for the attacks,”
However, the attack on Yahoo accounts was later revealed to be a state-sponsored attack by Russia. Thanks to the Federal Bureau of Investigation.
Mayer added in her testimony that “We now know that Russian intelligence officers and state-sponsored hackers were responsible for highly complex and sophisticated attacks on Yahoo’s systems.”
