It's pretty remarkable how long Equifax has been aware of the problem and did not disclose it. The main problem here is the failure to disclose a catastrophic cyberattack that compromised the information that is at the heart of Equifax's business model. This created a duty to disclose this attack in a timely fashion to investors, potential investors, and those whose data was compromised.
Equifax's delay in disclosing hack could be next major next legal problem for embattled company.
