Equifax: Number of US Breach Victims Rises to 145.5 Million

Equifax late Monday said forensics investigators have concluded that some 2.5 million more US consumers were affected by the data breach it revealed early last month, bringing the total number to 145.5 million. 

The latest victim headcount comes as Mandiant, which is conducting the breach investigation of Equifax, confirmed that the attack only affected the firm's databases in the US. Initial speculation by Equifax that some 100,000 Canadian citizens were affected by the breach were incorrect, according to the company. The actual number was 8,000.

Equifax said its UK forensics investigation analysis is not yet complete.

"I want to apologize again to all impacted consumers. As this important phase of our work is now completed, we continue to take numerous steps to review and enhance our cybersecurity practices. We also continue to work closely with our internal team and outside advisors to implement and accelerate long-term security improvements," said Equifax interim CEO Paulino do Rego Barros, Jr.
