Usage Note
Hacker is an anglicism used in French with the same ambiguity as in English — it can mean a malicious cybercriminal or an admired technical expert depending on context. The French official alternative is pirate informatique for the criminal sense, but hacker is dominant in tech journalism. It is masculine, and the verb hacker ('to hack') is also used informally.
Examples
