Re: Wi-fi. Approaching customers

I'm not sure I can help you on the contacting process, but question you assumptions.

My company has made a conscious decision to leave our WiFi open to visitors, while our internal machines connect via 
IPSec on the open airwaves.
A drive-by would show the open nature of our WiFi, but wouldn't immediately tell you that we've secured our business 
fairly well.

Gregh,
IMO, you're covered legally. I know it sounds fishy to approach a
potential client already knowing they're insecure...but don't all of us to
that on a regular basis? I mean I will hit google with a vengence before I
go into the kick-off meeting...I want to know what I'm up against.
I would respectfully request some time from a technical manager to present
your findings (show a kismet/netstumbler scan) and explain the dangers
(not the solutions of course). Hopefully, this will rattle the manager
enough to get the word up to upper management, and if you've left some
marketing material for them to look at, they can contact you for your
services.

Good luck!
Wade

I have asked this on another list and there has been discussion but
nothing that really seems like an answer so I am asking for help in here.


I did a war drive (and in MY terms that means just driving along
gathering SSID data showing open and closed and nothing else BUT that)
and found one HELL of a lot more wi-fi in my area than I had previously
been aware existed. Most of the SSIDs broadcasted didn't openly identify
the company involved though most of them were open. The idea in doing
this was that I could note an area where wi-fi is and approach the
company (or individual) and offer my services to LEGALLY lock their open
wi-fi down. I realise that with open wi-fi, I could be doing anything I
wanted to or with their systems but that isn't the point. I work in the
area doing I.T. related work and so far have a very good reputation for
an inexpensive service and I am self employed so doing the wrong thing
would quickly kill all that.

My question is, then, how to approach someone to legally get work from
them fixing their badly installed wi-fi and ensuring it is all locked
down. If I turn up saying "Your wireless networking is open to hacking
and I can fix it" that sounds somewhat suspicious to me if you look at it
from the point of view of a user who knows nothing much about it all. Eg,
I am telling them something they don't want to hear, for a start and then
telling them that if they pay me, they can have it fixed on the spot. I
already know how strange it can sound. I happened to pick up the SSID
ToysRus which was open and realising they would have their own company
employed I.T. people, I just rang them to do them a favour and wasn't I
met with suspicion? Yep! All I did was say "You know you have wireless
networking?" and they answered "yes...." and I added "It's open and
unsecured. You better fix it before someone else finds it" and then got
asked 100 questions including "How do YOU know?" blah blah by someone you
would think KNOWS the game.

How do YOU approach prospective new customers to tell them their wi-fi is
unsecured and needs attention and that you can fix it for a fee?

Any help appreciated.


Greg.
