Because the FTC publishes fraudulent cases like this one on its web site, bad guys can use this information to create a phishing attack that appears legitimate. The real FTC cases are posted here: https://www.ftc.gov/enforcement/cases-proceedings/refunds.
The phishing email being disseminated this week appears to be from the FTC; it recounts old facts from the J.K. Publications case and promises you a refund check. However, the FTC will not send you an email telling you that you need to take action (like click a link or attachment in the email) to receive a refund.
Rule of thumb: Any time you receive an email from an official-sounding organization promising you a refund in a particular dollar amount, be extremely wary of it. Do not click links and do not open attachments to emails like this. Delete the email.
