This package is used in concert with the cyber package to make documents with annotations of compliance with cybersecurity requirements. When you include this package, some notations of compliance are added to section names as seen in the table of contents of the final document. It also makes your document more brittle in unexpected ways: for example, when you use cybercic in the same document as hyperref, you cannot use any formatting in your section titles. So don't use cybercic unless you need to.
