If You're Going to Commit a Crime Keep it Quiet
If you're going to be one of those blokes who goes out and commits a crime it would probably be smart to avoid bragging about it. What would be really stupid is going on television and bragging about your capers which was the mistake made by a French hacker who is now in custody:
A French hacker has effectually tied a noose around his own neck when he bragged about hacking into the systems of a big government contractor on national TV.
He participated in a France 2 television program called "Complément d'enquête" (Further investigation), and he said - and demonstrated - that he has gained access to computers belonging to the French Army and Thales Group, a French company that provides information systems and services for the aerospace, defense, and security markets.
What I said goes double if your crime is against the government or its military. Doing crime is the government's job and they don't like competition.
