The U.S. Securities and Exchange Commission (SEC) has issued new guidance requiring publicly listed companies to disclose when they've been hacked.
"The market regulator has let firms know that they can no longer hide cyber attacks if that attack could cause financial damage to the company or make the financial information available to potential investors misleading," writes The Register's Brid-Aine Parnell.
"US Senator Jay Rockefeller had asked the SEC to issue the guidelines to help investors make more informed decisions," Parnell writes.
