I've got it installed on the laptop so that I can take a play around
with configuration and poke at the software.
Take a look at the
feature list (<a href="http://www.asterisk.org/index.php?
menu=features">here) and see if you have the same response that I
had: OMFG! (heh) I only need about two of those features for what I
want to do but I'll probably stand up a full blown install at a later
- Authentication of Evidence
- Information Assurance Services
- Information Assurance Applied to Digital Evidence
- Digital Video Evidence System
- Generalized Information Assurance Solution
- Daubert Compliance

numerous "stars" were inconvenienced or lost part of their "privacy".
The local news show did the usual sensationalist "what can hackers get
from your cell phone" bit.
I just wanted to make a comment that things
are only going to get worse as we buy personal video players with
wireless capabilities and camera cell phones with Internet capability.
The politics are only going to get worse also.
As an example, there's
a group in DC called "Enough is Enough" that is upset that Congress has
not prevented Playboy from making their content available via WAP.
Seems that parents are concerned what their teenagers can download with
their Internet-enabled cell phones.
Ten points to anyone who can come
up with what parents should do if they're actually concerned what their
children do with cell phones.

but, what the heck, I like tweaking the wireless box.
In any case,
here's the page for the Adhoc On-
demand Distance Vector (AODV) kernel module for reactive routing.
In other words, I want to try mesh networking. I'll keep you posted.

causing my return traffic to go to someone else's network. At one
point, I had a nasty routing loop which spiked the traffic level.

on it) and I'm able to separate the wired from the wireless in-house

- RTFM - it helps to read the docs and the stuff available
on the website (especially the part about what happens if you hold in
the reset button while power cycling)
- most of your custom
changes goes in S99done, NOT S10boot!
- trying to
stand up an additional AP is harder than replacing the original
- keep notes on everything, draw a basic network diagram and
label the interfaces
- have a backup copy of a working
firmware before you make any changes
- extra cables come in
- installing the tcpdump package as early as possible helps
- and, again, RTFM!
I have a request to all
the other OpenWRT users --> document how you did it so the rest of us
can benefit (I'll post mine shortly).

Honeypot is the reaction to a new type of malicious web traffic: search
Here's my take on it (please correct me if I'm
- It's not a new type of malicious web traffic. Google's
spider generates the traffic (it's legitimate traffic). At that point,
exposure is your (the owner's) problem.
- It's not a new type of
malicious web traffic. It's a reconnaissance technique and is not
necessarily malicious as the tools/techniques are available to
- I think it slightly misses the definition of a honeypot in
that attackers are researching known exploits via Google and are getting
pointed towards GHH. At best, you might get a list of IPs attempting to
exploit a vulnerability.
- As GHH relies on Google entries to
point to the honeypot, it lessens Google's accuracy just a bit more
(little though it may be).
That said, I'd still like to try
it out as it IS an interesting approach.

Two amateurs performed a make-believe (the article says "hypothetical") study of that old horse called "mine-is-more-secure-than-yours" and announced a winner, but then said that they couldn't afford to include any other OS's other than the two worst to begin with? Does anyone else smell sensationalism? Or stinky feet (sock puppets)? Why don't they just say that your kids are danger or that old people will die?
Anyone else in 757 want to help do a study on these studies? It might get us into a Con or two...
Encrypt" is referenced often when discussing cryptography and
crypto tools. Basically, it's a study of the shortcomings in the PGP

The following URL's show up in unending attempts to post comment spam to the blog:
All of the above translate to IP address 22.214.171.124
A WHOIS lookup of 126.96.36.199 results in:
A WHOIS lookup of future-2000.net results in:
A WHOIS lookup of ronnieazza.com results in:
As both registrants are in the middle of Manhattan Island at addresses that do not correspond to any mailing address known to Google or Yahoo, I'm willing to bet that they're fake. Let's take a look at the mailing addresses for the technical and administrative contacts.
A WHOIS lookup for support-2000.net returns:
Ah, it's that nice Registrar in France: Gandi. How about the other? A WHOIS lookup for support-24x7.biz returns:
Yep, the nice Registrar again. Let's look at mail servers...
The mail server for future-2000.net is:
Hmm... Doesn't exist. If we ask ns0.future-2000.net we get:
So it doesn't exist. An "A" query for future-2000.net (just in case it's an explicit name rather than a MX) yields the similar results. Actually, any query to ns0.future-2000.net returns only pointers to the root servers. This might be valuable later in complaining about the domain.
Also, please note that the root servers indicate that the domain is served by ns0.future-2000.net and that it is at 188.8.131.52. This most definitely is valuable when we look at server headers below.
The mail server for support-24x7.biz is:
Let's see if we can grab web server headers:
This could be the standard redir that some of the registrar's have started doing. (Yeah, even Network Solutions uses this unethical practice.)
Ah! Not a redirect! Grabbing www.future-2000.net returns a page that looks like:
This former info is currently under investigation - Due to mis-proper use of the hosting account
In the above, I disabled the following two lines:
<form name=frm method='post' action='
http://184.108.40.206/submitAbuse.php' onsubmit='return checkSubmit()'>
Somehow, I'm still not convinced. Let's take a look at that IP address. A reverse lookup of 220.127.116.11 returns:
A Google lookup on "shetef.com" leads to a slew of bloggers who've gotten this far and have complained about a spammer and are looking for someone to pound.
A WHOIS lookup on the 18.104.22.168 returns:
Just to play it safe, let's look at WebStream also. A WHOIS returns:
A DNS MX lookup on shetef.com returns:
The mail server for shetef.com is in yet another IP range? A WHOIS lookup on 22.214.171.124 returns:
A DNS reverse lookup on 126.96.36.199 returns:
Remember the WHOIS lookup for future-2000.net? It had the following DNS servers:
A WHOIS lookup on dns2005.net returns:
Again, Gandi.net. Also note the IP addresses for the DNS servers: 188.8.131.52. We've seen that one. It's our friend shetef.com again!
How about the DNS servers for ronnieazza.com? A WHOIS lookup on manage-dns.net returns:
Again, the Gandi registrar and the shetef.com DNS server. How about MX records for those two?
A DNS MX lookup on dns2005.net returns:
A familiar failure. A DNS MX lookup on manage-dns.net returns:
So MX records for manage-dns.net aren't configured. Remember that the WHOIS lookup for manage-dns.net points back to 184.108.40.206. Let's take a closer look at that IP. Remember the reverse lookup on 220.127.116.11 returned:
and that the MX record for shetef.com returned:
Connecting to port 25 on the mail server returns:
Pointing a browser at http://shetef.com () indicates that shetef.com is an Israeli software seller with the following info:
Grabbing the server headers for shetef.com returns:
The domain websitewelcome.com is registered via Enom, Inc. who does not give out their customer's domain info.
Grabbing the web server headers for http://escape.webserverwelcome.com returns:
Pointing a browser at http://escape.websitewelcom.com brings up the standard cPanel default page. So does pointing the browser at the IP address.
Performing a Google lookup on websitewelcome.com reveals that that domain appears to be a reseller client of hostgator.com. Suspiciously, it appears to be their only reseller client. One of HostGator's features is that reseller clients are allowed to host unlimited sites.
Pointing a browser at http://www.websitewelcome.com returns a directory listing.
Going back to shetef.com, a Google search reveals that CodyTheFreak is quite unhappy with shetef.com. He also points out a few extra domains. It appears that CodyTheFreak and I are the only ones that have traced the spammer back that far and have complained about it. All other Google entries appear to be spam for the shareware/software available on shetef's site.
I've probably missed a bunch of stuff associated with this spammer, but as I've spent the better part of a Saturday afternoon working on this, I'm going to drop it here.

To add to what Richard has said:
- Brian was pressed for time towards the end so he started talking faster (syllables and inflections intact). So much so that only those of us from NY could understand him.
- There were some shenanagins at the conference but not enough to involve evictions or law enforcement. (Those involved will have to incriminate themselves.)
- Richard's picture of Renderman wearing his warpack doesn't do it justice. In the picture, it's disassembled, missing the two antennas that stick up about two feet higher than that hat, missing the cables, and missing the other hand-held antenna (that's only one he's holding). Someone out there has a better picture.
- Here's a version of the story about the vulnerability that the Shmoo Group demo'd during the closing of the Con.
On behalf of the entire conference, I'd like to apologize to the religious group(s) occupying the two floors (of conference rooms) above us. We're not evil, we're just drawn that way. (At least three older women ignored my attempted Jedi warning of "you don't want to go down there" and rounded the corner just in time to see the word "fuck" displayed on a large plasma screen display.) Someone in hotel booking had a sense of humor, booking the hacker convention on the bottom floor and filling in with church groups above.
Lastly, I propose a game for next year. DefCon has "Spot the Fed". Given the location and the size of the conference, spotting a Fed would have been too easy. How about we run "Spot the Author" as an east coast game? I was able to meet/talk to/drink beer with Jason Scott and Richard Thieme. I molested Johnny Long for an autograph and would have liked to meet Richard Bejtlich and a few others. Rather than throwing a party at a club across town, have the authors hold court in the lobby bar and pay their tab (Rumor has it that the mostly non-author liquor sponges went through $6K of free booze at the club in less than a hour.) (For the math challenged, that's a bit over $100 of alcohol per minute.).
Oh, and thanks to the GrayArea.info bunch for fronting for those of us that were avoiding the dress code and the DC cab ride.

Saturday: "Life sucks." However, he wasn't talking about his own life.
He was justifying why we, as security professionals, should make things
simple and safe enough for the inbred yokel to use.
None of that is a
direct quote but you get the idea...
interesting stuff is coming for Snort: New data acquisition modules
(you'll be ablt to take the packets rejected by your IPFW/IPTables/etc.
and feed them into Snort for analysis). New stream reassembly modules.
IPv6. New defrag modules.
Based on the presentation and depending on
how it's implemented, Snort could get very complicated for production

To be fair, I won't name it/talk about it until they post it.
In any case, the con started nicely. Bruce Potter gave the opening speech, embarassing both his wife and his mother. (If Heidi blushed any harder, she'd probably fall over.) Bruce needs more hecklers (he can handle 'em). He introduced the rest of the Shmoo Group (that were present). Anyone missing was declared "at the liquor store" by those plants in the audience.
Although Brian Caswell's (AKA Cazz) talk on autoloading Snort rules amounted to watching someone show off a script, it was entertaining and evoked some thought. Brian needs fewer hecklers but the argument over crypto was funny.
It was a bit scary seeing Tina Bird wander through the audience with her CAT-5 of nine tails. The guys in the front row were having a good time with the Guiness and shots. Rodney needs to get over the little things.
Sightings include: the Shmoo Group (of course), various of the Ghetto Hackers, Dark Tangent (who autographed at least one book at the Culture Junkie stand), various acronym'd people and 757. I haven't seen so much leather, hair (or lack of), and body piercings since the Friday night when I was stranded in Port Authority (NYC).
Immediately after the scheduled talks, Tina was seen with a group in tow, headed into town. People that were interested in the whip? Where were they going?
