University-wide use of cracked OS and software – how to fix this?
If you suspect pirated software is being used, you can report it either directly to the software publishers themselves, e.g., to Microsoft, or you can file a confidential report online with one of the various software industry trade groups, e.g., the BSA Software Alliance or The Software &amp; Information Industry Association.  (SIIA offers rewards.)

Realistically, it's the publishers' responsibility¹ to protect their intellectual property, not yours.  So once you've made a report, I'd let the matter drop.  The publishers' attorneys will take it from there.  They know how to fix blatant cases like the one you describe.  Typically what they do is offer a carrot and a stick, the carrot being a very attractive "get well" price to replace all the pirated software with legitimate copies, and the stick being the threat of a lawsuit.  The objective isn't always so much about getting paid for software previously pirated as it is about turning pirates into paying customers, changing their practices to ensure they always buy legitimate copies in the future.
