"Aura" in this case is probably a complex and largely unconscious symphony of body-language; the way you carry yourself, how you regard the territory, even the fact that you are clearly *going somewhere*, shifts you from the Potential Victim to Potential Threat category.
The often-heard advice, when in a potentially hostile urban environment, to act as though you have business there and are headed toward some specific destination, is good advice for this reason. Even if you yourself don't look dangerous, you just might have friends in the immediate vicinity.
They watch for the weaker sheep, always.
