Spear Phishing
When a hacker tries to phish a specific individual, it is called “spear phishing”, targeted phishing.
These spear phishing emails can be harder to detect than mass phishing emails. 
They can:
- Appear to come from someone you know
 - Can be very carefully written
 - Can be very carefully designed
 - Be based on research about you
 
However, they can still use fear (threatening or urgent tone) to motivate you into action, and exhibit other red flags.
