This article from infoworld shows up 7 different types of hackers offering a nice explanation. I like taxonomies and I also use to catalog hackers during my classes, depending on targets technical skills and social background (for example, political, social, religious and so forth). For this particular reason I do like Grimes' taxonomy on the Hacker Differentiation.
Roger Grimes' Hacker Taxonomy:
- Cyber criminals
- Spammers and adware spreaders
- Advanced persistent threat (APT) agents
- Corporate spies
- Cyber warriors
- Rogue hackers
Today I suggest the small reading from infoworld, it provides a clear evidence of what are the differences between malicious hackers helping people to prevent attacks by keeping out systems from their intents.
