When I was an Oracle DBA there were several of our programmers from India that would open emails with "free" programmer utilities software or something similar and their laptops would go nuts! Our IT manager/Unix admin fellow would have to wipe their computer then reinstall everything from a backup. We kept the databases on stand alone servers, weather production or test or upgrades ETC so the application(s) could read/write data using Oracles comms software. Finally the worst of the trouble causing programmers would get let go. Fortunately Oracle had/has really great software utilities to let the DBA monitor users, activities, reports or other activities and let you see who is connecting or trying to and Oracle would notify me of strange activities.
