          The court proceeding are usually public, you can just go to your court house in your county and sit through the whole day and make fun of stupid criminals that steal phones.

          Now in most states (not in Ohio, Hamilton county yet), there are companies that will compile and publish the records online for a fee. Some counties just publish it themselves. It is always fun to check out your professors' or co-worker's traffic tickets and other run-ins with the law.

            That makes it impossible to just call that phone, yes. But the phone's IMEI number doesn't change, and that's what can be used to track it as well.
          • You're supposed to take the sim card out. That's what normally happens.

            Yes but this is only valid for GSM phones. With CDMA phones there is no SIM card. This is the thing that makes changing a CDMA phone complicated, since you have to call up to transfer the account, and I know that phone company support lines have a great reputation ;)

    Last Saturday, MoDaCo (the world's largest smartphone community) held a get-together for their forum members. Unfortunately the positive community spirit was soured by an individual who decided to steal one of the charity raffle prizes - a C550 mobile phone.

    On Monday, Paul O'Brien (MoDaCo founder) contacted me with information on the stolen phone's IMEI number. I operate the SPV-Developers community which offers the free online SPV-Services unlock tool for this type of phone. It seemed likely that the thief would attempt to remove the SIMLock using this service in order to switch the phone to a non-UK network - bypassing the UK's IMEI blacklist which renders stolen phones useless.

    Initially it seemed like there was little I could do to help. The SPV-Services server was not programmed to log the IMEI numbers of it's users. It seemed like a dead end, until I remembered something. When a user unlocks their phone, our server keeps a backup of the phone's first flash block (kept for a few days, in case the changes need to be reversed). This block contains 64kB of RSA-encrypted data such as the phone's SIMLock state, Carrier ID, and other concealed information - it seemed likely the IMEI would be buried within it. Shortly my suspicion was confirmed - after decrypting the block, the IMEI can be found inside (albeit scrambled with a simple transposition).

    I started writing a short script - which would check each backup in turn to see if it originated from the stolen phone. After 30 minutes of writing, testing, and running the script - we had a match! The stolen phone had been unlocked. The creation timestamp on the backup file gave us an exact time - August 21, 2005, 10:18:32 PM.

    The next step was cross-referencing this information with our web server logs. When a user uses our software to unlock their phone the software uploads the encrypted block to our server, which sends back a list of modifications which need to be made in order to remove the SIMLock. As we knew the exact time when this happened, we could find the corresponding web server entry :

            2005-08-21 22:18:32 POST /services/simlock_2.php -

    Bingo! I passed this IP address back to Paul who cross-referenced it with Modaco's database. From this, he was able to identify the guilty member. A quick lookup confirmed that the IP was used by the account "Cocky" - a member which had attended the get-together. The event registrations contained the name of our theif, and his mobile number. The next day, Cocky (AKA Krassen P.) received a short phone call:

            Paul: Hi, this is Paul from MoDaCo.
            Cocky: Er, Hi.
            Paul: You have something of mine, and I want it back.

    Not surprisingly, Paul could hear the faint sound of the guy crapping himself at the other end of the line. The phone was returned, via special delivery, the following day. Moral of the story - even if you're enough of a cunt to steal from a charity raffle, don't be fucktarded enough to steal a phone from a community of phone experts.

      Another slightly more detailed account of the same event:

      Detailed Account [modaco.com]

      Mono, Orange and Microsoft arrived early, and set out all of the stuff for the event... including the raffle prizes. The prizes were, foolishly it seems, laid out in the corner... footballs, kites, goodies and an SPV C550!

      We are not entirely sure at which point the phone was stolen... but a number of people witnessed what appeared to be the C550 being wrapped in a cardigan and placed in a bag along with a couple of other items including an Orange football, and a kite that was apparently discarded.

      At some point, probably prior to the raffle, the thief or his companion probably left the building, and took the C550 somewhere for safe keeping.

      As those present at the event will know, when the theft was discovered, Monolithix (who should be commended for staying calm!) offered the thief every opportunity to return the phone with no comeback, pointing out the phone would be useless anyway as it would be blocked on all UK networks... but nobody came forward. Having spoken to 'cocky', he said he was afraid to come forward.

      At this point, there was not a lot more we could do... we liaised with the staff at the Microsoft building, and determined that although there was no CCTV in the room, there was CCTV in the foyer.

      On the following Monday, I contacted Orange to ask for the IMEI of the stolen phone so that we could conduct investigations, which Orange duly provided. I also investigated whether we could determine whether the stolen phone had been used with an Orange SIM (99% necessary if the thief unlocks the phone), and Orange confirmed that they could do this, albeit with a 1 week delay. This provided us with one possible avenue... although for Data Protection reasons, pursuing this route would have required the action to be taken with the Police.

      I considered it very likely that the thief would have tried to unlock the phone... so armed with the IMEI of the stolen phone... I contacted the key players in the C550 unlock scene, Florin from IMEI-check and zone-mr from SPV-Developers.

      Florin confirmed that the phone had not been unlocked with IMEI-check... however zone-mr couldn't confirm immediately, as he only retains an temporary backup of encrypted data from the phone, which he wasn't sure included the IMEI

      A couple of hours later, on Monday evening, zone-mr contacted me to let me know he WAS storing the IMEI... and we had a match! Our thief HAD unlocked his C550... at 10:30pm on Saturday in fact! Even better news... careful analysis of the server logs on the spv-developers unlock server gave us the IP address of our thief!

      The next step was to find out as much information as possible about the thief. We determined their ISP and some other information, and thought about how to proceed. On an off chance that the thief was foolish enough to unlock the phone from the same connection they used to browse MoDaCo... I checked out the MoDaCo logs, and the MoDaCo sessions table.


      Our thief was logged on, and the logs were full of the IP address in question... all pointing to one user.... COCKY!

      Cross matching this address with the Event registration list confirmed that cocky HAD attended the event... and not only that... upon further consultation we determined that cocky was the person that witnesses had cast suspicion on.

      The next step was how to decide how to proceed, armed with the evidence that we were sure conclusively led us to our thief. I stayed up late on Monday night and prepared a dossier of evidence, with excerpts from server logs, witness statements etc. to pass to the Police. After a late night... I decided to sleep on it before deciding how to proceed.

      Tuesday came, and I decided that I was going to contact the Police... and spoke to both our contacts at Orange, and a contact at Orange security, about how to proceed. As the morning prog

      Most crimes are solved because the criminal tells someone, or does something stupid. (I don't mean miniscule stupid things like you see on TV with CSI, I mean really dumb things...)
      Sure there are some good, and thus rich criminals out there. But the majority of them are fairly dumb.
      • Nor is this coincidence. Smart people can usually find a better way to make a living than crime. (There are rare exceptions, of course.)
      • Sure there are some good, and thus rich criminals out there. But the majority of them are fairly dumb.

        Yup, the majority of people who find themselves in the "life of crime" don't do it because they're criminal masterminds looking to build their great underground lair, but because they're dumbasses who fall into the "lowest common denominator" of how to survive in a world with no marketable skills and few personal assets. Of course there are a lot more that do it to support drug habits and such.

          ...including looking around the back if the card is flipped over.

          • Every hotel I have stayed at in the past 10 years has NOT put the room number on the keycard. Some have some kind of code number, not the room number, but most are blank. They have a stack of cards at the front desk; when you check in, they pick one up and scan it, then write your room number on a piece of paper separate from the card. I only need to know the number to find the room the first time, then I just find it by physical location and usually forget the number quickly.

        Reminds me of a story a retired officer told me. Here's how it goes: A guy goes to rob a quickie mart with a plastic bag over his head, yet forgot something seriously critical to the "mission". He forgot to make an air hole so he could breathe. And while attempting to rob, he began to suffocate. The officer got there just in time to save his life. He would not stop thanking the officer as he was arrested. It's amazing how stupid some people are.

      In the end, isn't all good sleuthing just waiting for the criminal to do something dumb?

        There are many nearly perfect crimes that are solved due to one single clue... like leaving residue of specialty clay used to make masks when there is only one theatrical shop worldwide that makes and sells that specific mix, something the criminals did not know beforehand.

    If this had happened at the US Department of Homeland Security, they would have raised the alert level to Orange and we would be told to be on the lookout for slightly overweight middle-aged men with glasses, wearing dockers, using a cellphone.
    Anyone seen using a cellphone in a dark corner or putting a cellphone in an inside pocket (trying to conceal it!) will be immediately taken in for questioning.

    Henceforth, all cellphone usage will require a licence at the county courthouse, and people must submit valid reasons for having one, and give their fingerprints and DNA for registration.
