Sounds to me like the feds got involved already, and they're definitely going to want to make a big noise about this as a national security thing:
> “For us it is a matter of national security,” U.S. Attorney Craig Missakian said in a statement. [...]
> The case is being prosecuted by the National Security, Cyber & Special Prosecutions Section of the U.S. attorney’s office for the Northern District of California.
(But that was after OpenAI "referred the matter to the FBI")
There's presumably a strong argument for making this stuff known internally, since you want other employees to a) be on the lookout for it and b) get scared into NOT doing it themselves because someone else got caught.
If you tell your employees, the outside world is going to hear about it too.
