the.com/black hat
the hacker who breaks in for the loot, not the glory or the fix.
means a black hat is someone who exploits computer systems illegally for personal gain, malice, or chaos, as opposed to reporting the flaw.
from borrowed from old western films, where villains wore black hats and heroes wore white — the term crossed into hacker culture by the 1990s to split the community morally.
