Companies often refrain from disclosing that they paid ransoms to cybercrime groups after an attack, fearing that such an admission could bring legal and reputational risks.

The issue reflects challenges federal regulators face in forcing more transparency around how companies deal with cyberattacks. https://www.wsj.com/articles/companies-remain-reluctant-to-admit-paying-off-hackers-e1688946
