We decided to do a teardown on a Keylok USB based dongle from Microcomputer Applications, Inc. (MAI).
Opening the dongle was no challenge at all. We used an x-acto knife to slit the sidewall of the rubber protective coating. This allowed us to remove the dongle’s circuit board from the surrounding protective coating.
The top side of the printed circuit board (PCB) is shown above. MAI did not try to conceal anything internally. We were a little surprised by this :(.
The backside consists of two tracks and a large ground plane. The circuit is very simple for an attacker to duplicate.

From simple 2-axis milling and turning to complex Multi-Task Machining—GibbsCAM is the solution for programming the simplest to the most complex machined. You can think of the Dongle Emulator as a miracle. Think about the operation of your software and software analysis of the hardware connected to the USB or Parallel Port that meets its functions. I believe virtuality will show great improvements in the next century.
Now that the students must have a USB hwardware device to use the training, our concern has disappeared and we get paid for every course we deliver. KEYLOK was the only provider with a feature like CodeVault. And we chose KEYLOK for this reason. The Fortress RS dongle precisely fit our need for a secured key storage device. Finding a computer with a parallel port these days is tough, so as with all technology, adaptations were made. Now, USB is the defacto standard. These are relatively cheap to produce and are hard to crack. The fact of the matter is, depending on how the dongle protection is incorporated, it can be impossible to crack a program without the device. The Keylok Security Key Installation executable is found in the RMWIN folder security folder Keylock folder. Click on Install.exe. Note: in the screen shot above the computer is mapped to the rmwin folder on the F Drive. Choose the USB Dongle or Fortress Key option under the Dongle Type field.
With the devices removed, a schematic can be created literally within minutes. The 20-pin version of CY7C63101A can even be used in place of the smaller SOIC 24-pin package (which is difficult for some to work with). The 20-pin is also available in a dual-inline-package (DIP) making it a great candidate for an attacker to use.
Red pin denotes pin 1 on the device.
We performed some magic and once again we have success to unlock the once protected device. A quick look for ASCII text reveals a bunch of text beginning around address $06CB: .B.P.T. .E.n.t.e.r.p.r.i.s.e.s…D.o.n.g.l.e. .D.o.n.g.l.e. .C.o.m.m.<

Ironically, they say, “There are many advantages to using a hardware “based security solution AKA, a Dongle. There are even more advantages however to using KEYLOK Dongles over other competing solutions.”
Statement’s such as the one above are the reason Flylogic Engineering started this blog. We have heard this just one too many times from companies who are franckly pushing garbage. Garbage in, garbage out. Enough said on that.

This dongle is the weakest hardware based security token we have ever seen!! The outer physical protection layers ease of entry places this dongle last on our list of who’s hot and who’s not!
