Hacker Shuts Down Copenhagen's Public City Bikes System ( 72

An anonymous reader writes: "An unidentified hacker has breached Bycyklen -- Copenhagen's city bikes network -- and deleted the organization's entire database, disabling the public's access to bicycles over the weekend," reports Bleeping Computer. "The hack took place on the night between Friday, May 4, and Saturday, May 5, the organization said on its website. Bycyklen described the hack as "rather primitive," alluding it may have been carried out "by a person with a great deal of knowledge of its IT infrastructure." Almost 2,000 bikes were affected, and the company's employees have been working for days, searching for bikes docked across the city and installing a manual update to restore functionality. The company is holding a "treasure hunt," asking users to hunt down and identify non-functional bikes.

      Well, it's Denmark, so I if they weren't made to last in rain, they would have have a very short lifespan. Last year was nothing but rain. This year shows promise, crossing fingers.

      That's a lot of money there. How about an ESP8266 module and two AA cells? For less than $3, it has CPU, memory, and wifi. Mount it under the seat or wherever convenient. (The ESP12 is small!)

      The device could wake up every so often and listen for an open hot spot. Associate with the hot spot and "phone home" with the MAC address of the hot spot. That might be close enough to locate the bike without GPS.

      Meanwhile, volunteers could go war-biking with similar devices WITH GPS to make a database linking the MAC

        You have some great ideas there, you should apply and help them bring it to the next level. I'm sure you will be able to find alternatives to the other features that the tablet provides, such as:
        - credit card processing
        - usage time tracking
        - motor assistance settings
        - navigation

        - reservation

    I'm sorry if I don't know anything about Bycyklen, but how are the bikes "non-functional"? A bike is a bike, isn't it?

      There's generally some kind of lock that you need to remove in order to use the bike, not sure about Bycyklen specifically, but usually it's via some sort of bar through the spokes or pedals, or a clamp that achieves the same effect. Alternatively, bikes must be obtained from and returned to specific racks which lock them in place. Either way, unlocking a bike starts your registers your account for usage of a bike, and locking it again ends it. Since Byclyken uses GPS (and lost the GPS data when the DB w

    Mindless vandalism? I'm trying to imagine what could motivate such a crime. What sort of grievance could justify attacking a system that lets people borrow bikes?

    Just wants to annoy other people? Maybe he sells cars and he felt the bikes were hurting sales? Maybe he's just a mercenary working for the car salesman? Or maybe the prick did it simply because he could.

      See, boredom is a result of not being challenged (Csikszentmihalyi) and anger. And misdirected talents.

      This whole "only boring people get bored" is total nonsense. Anyone who has had to master a musical instrument or sport or science will know that periods of boring monotony are required for mastering these subjects. But there is a GOAL at the end.

      Breaking things or breaking into them gives a rush that you can't get without drugs. When you have no goal at the end.

      The right framework to understand this isn't psychology, it's statistics. The probability of an event occurring as the number of trials approaches infinity is either 0, or 1.

      That's the way to understand a lot of what happens in the world, like school shootings. If they can happen, given enough people who are capable of doing them, someone will.

        I'm afraid I don't understand what sort of point you are trying to make. Perhaps something like bad things happen, so we should give up?

        Do you have any sort of constructive solution to offer? (I do, but I've already presented it out on Slashdot and never detected any interest.)

        • by hey! ( 33014 )

          No, it's that trying to understand all the possible motivations people might have to do something like this is pointless.

          Early in the days of the Internet I would have clients challenge the need for security. "Why would anyone want to hack me?"

          And I'd answer, "The people you have to worry about don't think like you. Their motivations wouldn't make any sense to you, even if you knew them, which you probably won't."

            Simple counterexample will suffice to prove motivations count.

            Where is all of your pump-and-dump stock scam spam? It's gone because they studied the motivations and cured the problem. After several academic papers were published proving that the scammers were effectively shaking money out of the tree, the authorities responded by changing the rules. The motive was profit, the profit was removed, and that specific problem was solved.

            I'm not denying that motivations are difficult to figure out. In this case,

According to your rationale, it would also make no sense trying to understand terrorist events. Or airline accidents. Or very rare diseases. Or earthquakes - and so forth, you get the point.

            However, the fact is that inferential statistics only works and makes sense if you are able to make at least some reasonable assumptions about an underlyi

    Now imagine if this database were to be stored on a ZFS volume with regular snapshots, and those snapshots were sent to other remote machines for backup... The entire database could have been recovered in minutes with just a few simple commands to re-mount the ZFS partition to a given snapshot, restart the database server software, and you're up and running again...

    Oh wait, that's right. I'm too old for tech nowadays. There are all these kids fresh out of college using newfangled technology that don't know two shits about information security or data integrity to even give this a thought in the first place.

      Doesn't seem like they lost anything, the way you're describing it. Here's the initial announcement [], and here's the update []. Doesn't;'t seem like they lost anything in their database.

      What seems to have happened is that the hack has managed to erase the client side. Either poison data/commands has erased the tablet they attach to the bike, or the tablet still has data but is now out of sync with their restored backup. That will be why they're talking about going round rebooting the tablets on the bikes - it's the client side that's wrong, ZFS-nothing - it simply wouldn't have helped.

There are setups that are better with continuous logs and high tech breach detection which would either prevent this or have virtually no downtime.
