With the recent news about the SEC data breach, people are looking towards their own internal security practices to ensure they are handling their data responsibly and doing everything possible to prevent their own data breaches. In the financial document preparation and submission industry, one of the most common pieces of private data that is passed back and forth through email is a filer’s CCC. To file a document on behalf of a company, you only need their CIK (which is publicly available) and the CCC (which is not supposed to be publicly available). It follows then that if an unauthorized entity obtains a CCC, they could fraudulently file on a company’s behalf to the SEC. So it’s in your best interest to keep your CCC secret!
