That brings the total number of Americans affected somewhere around 148 million.
The regurgitation of these fresh people's data isn't quite so unpalatable as it was when the original 145.5 million Americans (and another 15.2 Brits... plus some 100,000 Canadians) had their taxpayer IDs exposed, given that less sensitive personal data was involved, Equifax said.
The firm was also keen to stress that this was not newly stolen data. The company said that the affected consumers weren't previously informed because their Social Security numbers and driver's license information "weren't stolen together".
Equifax Inc said it expects costs related to its massive 2017 data breach to surge by US$275 million this year, suggesting the incident at the credit reporting bureau could turn out to be the most costly hack in corporate history.
Equifax claimed the reason it had not recorded the stolen data until now is because its forensic investigators had focused on Social Security Numbers (SSNs).
"It is possible that further analysis will identify additional consumers affected or additional types of data accessed", Equifax said in a regulatory filing on Thursday.
"This is not about newly discovered stolen data", said Paulino do Rego Barros Jr., Equifax's interim chief executive. Information about registering for these services will be included in the notification.
"We continue to take broad measures to identify, inform, and protect consumers who may have been affected by this cyberattack", he added. This new service, which is free for life, enables consumers to quickly lock and unlock their Equifax credit report using a computer or app downloaded on their mobile device. The company's quarterly revenue was up 4.7% on a year-over-year basis. equities research analysts predict that Equifax will post 5.92 EPS for the current year. On January 31, the company launched a mobile app called Lock & Alert that allows consumers to lock and unlock their Equifax credit at will to stop some of the potential abuses of the stolen identity data.
Since announcing this incident, Equifax has taken steps to communicate with and assist consumers and customers. Nor do they take such credit-protective, identity-theft-thwarting advice to heart. Finally, Royal Bank of Canada boosted their target price on Equifax from $113.00 to $114.00 and gave the stock a "sector perform" rating in a research report on Monday, November 13th.
The company's shares fell 1.3 percent at $111.50 in New York Stock Exchange trade that closed before the results were released.
