The behavior Dan Tentler exhibited screams "troll" to me, and his intentions 
were clearly selfish: whether to surreptitiously obtain personal/private 
information for his own benefit, or to get personal satisfaction by riling the 
group.  He claims to be a "security professional" but Dan Tentler's 
unprofessional actions demonstrate his *inexperience, immaturity, and 
dishonesty*.  This kind of thing might have been fun in high school, but it is 
not the kind of thing I've come to expect from a 29-year old adult.

Had he been interested solely in educating the group or even individual members 
of the group, a real professional would have given prior notification, and 
maybe even asked permission.  Dan Tentler did neither.  His actions were 
trollish.  Yes, we can all learn from his improper deeds, the same way we can 
learn from any terrorist attack or natural disaster.  We don't have to be 
thankful, though, for his unethical methods.

It would be like somebody breaking into your house (even if they went through 
an unlocked window, to make the analogy a little better), taking your checkbook 
and diary, and then, when you see him walking out of YOUR house, holding YOUR 
personal items, and challenging him, he gives them back and says, "Oh, it's OK, 
I'm a professional.  I didn't really see anything, like your wife who is 
currently in the shower and is using the wrong shampoo.  And I didn't read your 
diary, or at least I promise not to remember what I read, and I TOTALLY SWEAR 
that I didn't write down or copy any of your financial information.  By the 
way, you're nearly 2 months late on your car insurance."

"Plus, you really need to lock all your windows, because it was just that easy 
for me to get into your house.  You're welcome."


Dave said, of Chris and Roger, that "[...] they have the right to be upset 
about the potential serious loss of privacy."  I disagree - this was not a 
*potential* loss.  It was a *violation of privacy*, period.

I don't know Dan Tentler, but had I been at that meeting, I might have called 
the police.  Seriously.  Anybody sitting in that cafe had a "reasonable 
expectation of privacy."  Dan Tentler violated that privacy, and by being 
associated with the group, violated the trust of the members.  I know of at 
least one person on this list whose life has been severely disrupted because 
their identity was stolen; I'm pretty sure that person would have called the 
police if they had been there.

Further, his claim that Roger - or anybody - is merely on a witch hunt is 
ridiculous.  "Witch hunt" implies that Rog is seeking to defame him within the 
group for other political or financial reasons.  The group has no offices, 
officers, officials, leadership positions, appointments, elections, committees, 
boards, faculty, or any official hierarchical structure of any kind, so 
political motivations aren't even possible.  There are no dues, fees, or 
charges of any kind to be a member or attend a meeting, so financial motivation 
is also out.  So, I'm curious Dan, what would Roger's ulterior motive be?

Hi Paul,

Detecting sniffing is really difficult to do.  It would be like two
people talking in a room and you want to know if a 3rd person in the
room is eavesdropping.  That someone else is not an active participant,
and without being able to see inside the head of that person or know
what they are thinking, you don't know if they were listening in or not.

As far as giving someone the benefit of the doubt - if you are still
interested in my opinions, read the remainder of this e-mail.

When the issue with Dan Tentler being dishonest and stealing people's
passwords first arose on Saturday night, he had numerous chances to be
honest, contrite, forthcoming, and at least try to explain himself
properly - and he didn't.

When Chris first asked who was running nessus, he just looked down and
ignored the question - when he should have immediately responded and
explained what he was doing.

When the question was repeated he looked over in the direction of Chris
Louden and myself as if to deflect some blame towards one of us.

When Chris really found that he was the culprit, he passed it off as if
it was some research project.  When the issue of having intercepted
gmail passwords and such came up - he made the comment that it was all
harmless because he wasn't going to save the log of his capturing
activity.  Yet he didn't - he kept right on capturing other packets,
and didn't actually demonstrate that he had cleared the captured log.

So - let's revisit back to giving someone the benefit of the doubt -
there were numerous chances during the conversation as it developed that
evening, where he could have provided us with a reason to supply that
benefit, where we would be generous with our opinions of him - but every
time he chose the wrong course, with either denial or dishonesty.

In further discussions about the issue Dan is still not coming clean or
apologizing, but instead accusing people of being on a witch hunt and
accusing people of starting a flame war.

If you want to give him the benefit of the doubt, please do - but people
that started off trying to give the benefit of the doubt were quickly
convinced that he didn't deserve it based on his actions.

I still don't have any proof that Chris's gmail password wasn't sent
off to Chinese hackers or something by the time we got home that evening.

None of us observed if Dan actually deleted his logs, or that he proved
to anyone that he hadn't captured anything else of ours that evening.

He has not provided any proof of deniable culpability - and when someone
like him is observed doing the activities he was doing - proving to
everyone that he was clean should have been the very first thing he did.

All in all, it's a shameful act for someone who claims to be a security
professional.  Security professionals only do what's within their
bounds, and don't shrug at legalities like Dan Tentler did.  Security
professionals don't infringe on people's privacy for sport like Dan
Tentler did.

Also on the topic of lending someone the benefit of the doubt - I think
when it comes to a person's privacy (and each one of us has to evaluate
this as it equates to our own personal information and how we choose to
guard it) - people also need to give the benefit of the doubt to anyone
who is guarding their personal info.

I've been generous with giving that benefit to Chris and Roger as they
were most affected by Dan Tentler's mischievous and borderline-illegal
actions.   Based on how they are handling things with a professional
manner, and how Dan is not - I continue to give them the benefit of the
doubt that they may have had something more serious than a gmail
password be compromised, and they have the right to be upset about the
potential serious loss of privacy.

Thanks,
DK
