When I see the word "cyber", it is a good indicator that the speaker who uttered this word has absolutely no idea what they are talking about. This is usually underlined by their business card using the same word (such as "head of cyber security"). The sheer existence of business card is by itself a huge red flag, unless it is really cool.

For crypto, I prefer cryptocurrency, ecash.

Cyber and virtual are worst (fatf-gafi picked one from this set, which is telling). Any mention of blockchain is also a red flag.

For security, I prefer ethical hacking, penetration testing, it security or simply security .
