The credit reporting agency revealed earlier this month that hackers had accessed the information of some 143m Americans – including some who had no idea the company was collecting their data. The exposed information included social security numbers, birth dates, addresses, and even credit card numbers.
The breach – the result of an unpatched flaw in the website’s software – is said to be the worst in US history.

At least 30 lawsuits have been filed against the company. In the suits, Equifax is accused of misleading shareholders about its ability to protect consumer data and inflating its financial statements before the truth became known.
