I am looking to try my hand at the "White Hat" life. There are a ton of open networks in my area, and I would like to expose vulnerabilities to the owners. To do this, I would like very much like to find where I can find an internal wifi adapter, so that I may attempt my audits discreetly. Everywhere I look, there are only USB options available. HOWEVER, If I see a wifi dongle with an antenna, they are at only about 1:100 ratio. These days seeing such stands out (at least in my area), and it would seem as though I may as well wear a sign to go along with it.
Please assist me in finding an effective solution to match my needs.
Thank you so very much.
