There was definitely another shift earlier this year. Previousy there were cyber attacks, cyber threats, cyber defenses, cyber crime, but the field and the subject matter was cyber security, not just "cyber". The security part could just be covered by the associated word, or by a military context. A "cyber sleuth" was still just someone doing research "in cyberspace".

That seems to have changed this year as part of AI marketing. AI models have "cyber capabilities", or are described as being "good at cyber". Anthropic announced a "cyber mission" and has a "cyber verification program". I saw a company referred to as a "cyber firm".

A cynical explanation could be that this is because it's pure marketing, and the full term risks diluting the message. If you keep mentioning "security" people might notice the actions don't line up with the presentation.
