[Alex] just bought a really nice TEAC VR-20 audio recorder, a very capable recorder perfect for recording your thoughts or just making concert bootlegs. This model was recently replaced by the Tascam DR-08 audio recorder. It’s essentially the same thing, but the Tascam unit can record at 96kHz, whereas the TEAC can only record at [...]

The mechanical simplicity of this pull-string controlled most useless machine is delightful. You can see the metal gripper which is reaching up to tug on a light-fixture-style pull chain. This is how it turns itself off after you’ve pulled the string to power it up. The device is [Alex555's] entry in the 7400 Logic competition. [...]

We love to see derivative works that take a great hack and make it even better. This LCD Laptop resurrection project is an excellent example.

[Alex] was tasked with a control design problem for a set of motors. The application called for the back of a truck to open up, some 3D scanning equipment to rise from its enclosure, and finally the equipment needed to rotate into place. All of this needed to happen with one flip of a switch, [...]

[Alex] has been working on a diesel motorcycle project for a few months now, and the project is finally bearing fruit. It’s quite an accomplishment for something [Alex] describes as an industrial Chinese engine, a modded Honda Superdream, and a few Royal Enfield parts thrown in for good measure. [Alex] bought his Honda CB400 from someone [...]

[Alex] built an add-on board for his TI launchpad that lets him use it as a wireless controller for an RGB lamp (translated). As you can see above, the board has a pair of female pin-headers which make it easy to install or remove the board. This way you can use it for other projects without [...]

Let’s get this straight, [Alex] is going to show us how to make controllers like this one? Where do we sign up? Even without seeing it in action we want one, but the urge to build is even greater after he shows it off (check the clip after the break). He’s a design student who [...]

In the hopes of getting a heads up on when the aurora borealis will be visible from his back yard, [Alex] built a magnetometer to measure disruptions in Earth’s magnetic field. The build is extremely simple, too. It’s amazing what you can build with a few components and a trip to the dollar store. The design or [...]

[Alex] got his hands on an Epiloge laser cutter the easy way — the company he works for bought one. We’re sure he’s not trying to rub it in, but he really does make the tool look and sound cool in the post he wrote purely to show off the new toy hardware. This model is [...]

Meet Boxie. He’s a robot videographer with levels of interaction we haven’t seen outside an episode of Dora the Explorer.

Those of us with 3D printers have had two major choices when selecting a material to print with – ABS, a very hard plastic, and PLA, a more brittle plastic with a lower melting point.

[Alex] has reduced the resolution of his timepiece as a trade-off for speedy-readability. At least that’s what he claims when describing his color-changing clock. It uses a ShiftBrite to slowly alter the hue of the clock based on the current time. The concept is interesting: 12:00 starts off at white and slowly fades to green [...]

So first a disclaimer, i didnt listen to the referenced podcast, this is based solely of this blog post:
http://newschoolsecurity.com/2011/04/data-driven-pen-testsSo I’m listening to the “Larry, Larry, Larry” episode of the Risk Hose podcast, and Alex is talking about data-driven pen tests. I want to posit that pen tests are already empirical. Pen testers know what techniques work for them, and start with those techniques.
What we could use are data-driven pen test reports. “We tried X, which works in 78% of attempts, and it failed.”
We could also use more shared data about what tests tend to work.
Thoughts?
Dre's response to the post was surprising to me, he listed a bunch of tools that seem to do correlating of pentest results into a portal so you can trend over time. Cool idea, i'll give the people that. But to me when we start jumping into repeatable metrics driven stuff we are in Vulnerability Assessment land, not pentesting land.
Here is the comment I left:
I like the idea and i think it could be useful.However, they need to drop the pentest part. you are solidly into the vulnerability assessment part of things when you are talking about “ok, i tried 1,2,3,4,5 and 1 & 3 worked” ok on to the next set of tests… thats vulnerability assessment (with exploitation if you want to get technical) and not pentesting.
pentesting is about that human looking at the problem and figuring out how to break it, not some scanner, thats going to be very hard to standardize and put hard numbers on and i dont think its going to be possible without tying up your tester’s time with bullshit.
I'm all for "repeatable" pentests. You should have a methodology for each type of test, but when you are paying for human's time you should be paying for them to go after the site like a human would and not how a scanner would or not in a way where i'm worried about religiously following some checklist because if i don't the metrics get all fucked up. Your pentest should come after you have thrown the kitchen sink at it scanner wise.
as an added bonus this post was right below the new school post in my Google reader:
http://coding-insecurity.blogspot.com/2011/04/developing-good-methodology-part-3.htmlThis post and really any methodology document you will ever read or write will have gaps, because no document on this subject can ever really be 100% all inclusive of every vulnerability and the myriad of variations that exist for many of these.
I think it drives the point home as well.

This image was not made in post production, but captured during a long camera exposure. The method uses stencils to add components to a picture.

[Alex] knows his strippers. By his estimation, he has stripped millions of wires over the years, and he has seen his fair share of wire strippers come and go.

remote-exploit & backtrack
Hi,
I have a general question about making a Soft AP/Fake AP. If a client A is connected with an AP B, and the connection between them is using WPA2 (preshared key). Is it possible for me to act as AP B (with the mac and SSID belonging to AP B) and downgrade the connection in somehow?
With downgrade I mean making the connection use no encryption at all or using a weaker form of encryption.
Let's assume that I can use airdrop-ng to eliminate AP B.
?

remote-exploit & backtrack
Hello,
Before I'm losing my mind completely, I thought I should ask you about suggestions.
I'm trying to set up an soft AP with my Alfa AWUS036H
I'll start with a short description and we will see if someone already can pinpoint the problem from there. Otherwise I'm going to be more specific:
- I put my Alfa-interace in monitor mode with airmon-ng
- I start airbase-ng on the monitor interface
- I have configured my dhcpd.conf file and told the dhcp-deamon to work on the tap interface which is newly created with command airbase
- I set the IP on the tap interface (at0) to map to the correct IP which also is specified in dhcpd.conf as router and set the mtu to 1400 and bring up the at0-interface.
- I add the correct route to the specified net with the gateway set to the same IP as I specified on at0.
- I start the dhcpd and everything seems OK.
("Wrote 0 leases to leases file")
From my other laptop I'm able to see the newly created AP and I can connect to it but I don't get an IP from dhcpd.
If I run tcpdump on at0 the only thing I see is:
"12:24.069960 TheClient'sMAC (oui Unknown) Null > Broadcast Unknown DSAP 0x08 Supervisory, Receiver not Ready, rcv seq 0, Flags [Command], length 330"
What the h am I doing wrong? I am also able to see the client's request coming in:
"12:24 Client TheClient'sMAC associated (unencrypted) to ESSID: "secret"
I'm happy to give away all the conf-files and detailed descriptions, but I thought that I'll start with this light description and see if someone comes up with the solution or ideas.
Thanks / Alex

A diode allows current to travel in only one direction. With that in mind, [Alex] built a mechanical diode that will only allow gear rotation in one direction to be transmitted through the system.
