For the second time since it fessed up to suffering a data breach last month, Equifax has issued a correction, acknowledging today in a press release that hackers stole details on over 15.2 million UK citizens.

In its original statement, last month, the company said that only 400,000 UK citizens were affected. The company says the cyber-security firm it brought in to investigate the breach found evidence that hackers got their hands on more data than initially believed. The stolen files contained records the company created between 2011 and 2016.

Equifax says that for approximately 14.5 million of the 15.2 million affected, the stolen records contained only a small amount of information, limited to name and dates of birth.

The UK National Cyber Security Centre also issued a statement today, with recommendations for affected customers, informing them of the dangers of phishing and online fraud. Equifax also made it clear that it would not be calling affected customers. UK users should not give out personal details to anyone calling claiming to be an Equifax employee.

Second time Equifax corrects a breach estimate

This is the second time that Equifax amends its original breach estimate — 143 million US customers, 400,000 UK customers, 100,000 Canadian customers.

Last week, the company said it discovered an additional 2.5 million affected US customers and reduced the number of affected Canadian users from 100,000 to around 8,000.

Also last week, Equifax's Chief Executive Officer (CEO) Rick Smith resigned his position. Two weeks earlier, the company announced the immediate retirement of their Chief Information Officer (CIO) and Chief Security Officer (CSO).

Smith also attended a Senate Banking Committee hearing on the Equifax breach, during which he blamed the incident on a lowly IT worker who forgot to patch the breached server for an Apache Struts vulnerability. Despite Smith's statements, someone dressed as the Monopoly Man stole the show at the Senate hearing.

Despite Equifax's huge security failures, the IRS awarded the company a $7.25 million contract to help the agency prevent fraud. The company will probably do a splendid job at recognizing its own data now.
