darkreadingman writes, "A penetration tester tells how he broke into a bank's network dressed as a copier repairman. Some good lessons here — many companies spend millions on network security, but don't teach their employees how to challenge a stranger in the building. Social engineering at the company site can be one of the most difficult attacks to defend against."

I usually leave something behind and then contact the person who hired me and direct them to the mark. In this case I wrote his password on a ream of paper and tucked it under the machine."

      Card printers with stripe encoders are fairly inexpensive. In 2000, picked one up for a previous employer for $400.

      However, also being the guy who ran the prox card access system, I can tell you this: Prox cards are not easy to reprogram. They are usually hard coded with technology that resembles a primitive form of a RFID chip and small battery that only energizes when in the prescence of a mildly strong magnetic field (more than kitchen refrigerator magnets, but not as strong as the rare earth magnets you can buy for cheap), has a transmit range of 6 inches, and is attached to a antenna/induction coil loop that circles the length of the card about 5-10 loops.

      Theres a reason you don't leave a prox card on top of a unchielded stereo speaker... Not only does the stripe become scrambled over time, but the battery, which is constantly in the range of the magnetic field, will stay energized and keep broadcasting the signal untill.... well, until its dead. Typical prox cards are specced for about 10-20 access per day, with a usable lifespan of 5 years.

      Prox cards from HID (one of the biggest manufacturers of prox security equipment) are sold with a two-fold identifier: 4-digit site ID, and 6-digit card number. Yes, these are both printed on the card. Yes, HID keeps track of which company owns which site ID, so they can sell further stock in the future with the same site number...and also so they don't sell the same site number to someone else in the same region.

      Prox reader controllers (a closet component that is what the readers are wired to, each controller capable of holding a token-style chain of 127 modules that can each control up to 8 doors on each module) are programmed to accept only a certain set of site ID's. They keep a local database, updated at regular intervals from the master controller, a server (anywhere from 15 mins to an hour) of what card numbers within each site are allowed to access a specific reader/door combo.

      If the communications to the server is down, the controller tries to contact the nearest controllers it knows about (up to 255), which also keep the same database. If no redundundant communication to other controllers or to server is available either, the controller maintains its current memory and security settings for 72 hours from last communication. After that, no access is allowed at readers until communications are enabled again and a database synch is performed.

      Of course, this info is all dated to 2002, for Andover Controls security systems... but is pretty much standard to all prox systems.

When the penetration test is successful everyone just feels stupid and slightly used. That's my guess at how the bank employees would react when the boss let them know that they got totally hacked.

    Instead, for those bosses with less scruples, you'd probably get more bang for your buck by faking the penetration test. Hire some dude to try to get in, and arrange some employee to "catch" him. Then you get to circulate the news that you were successful because an employee did the right thing. I think the information would be just as instructive (always ask for outside confirmation of vendor reps), but instead of being depressing (you guys all failed to do the right thing) it could be empowering (it's easy to do the right thing, and one of you managed to do it).

    Is penetration testing even worth the money for a system as obviously insecure as this one?
