WiFi Exposes Sensitive Student Data

cfarivar writes "'Like leaving a vault open, the Palo Alto Unified School District failed to place a number of highly sensitive computer files containing student information in a locked location on its network. Using a laptop with a wireless card outside the district's main office, the Palo Alto Weekly gained access to such data as grades, home phone numbers and addresses, emergency medical information complete with full-color photos of students and a psychological evaluation."

    WEP (Wired Equivalency Protection) uses RC4 encryption which is not very strong. Due to the design of RC4 (it was intended to be used over a synchronous stream), WEP designers had to make the key change with each packet. This means that the keys are quickly reused, and thus a sinffer can eventually - and usually rather quickly in large networks - determine the key loop. The SSID (Service Set ID) is sent over the wire either unencrypted or encrypted using weak algorithims.

    WTLS (Wireless Transport Layer Security) was designed poorly as well. It's design limits the effectiveness that a certificate authority like Verisign can have when using WTLS.

      The key to understanding WEP is the phrase "Wired Equivalency". The theory is that WEP, although a fairly weak cypher, provides the same level of privacy as unencrypted wired Ethernet. That is, breaking WEP is judged to be approximately as difficult as finding somewhere to jack into a wired Ethernet (i.e. not very). WEP never was intended to take the place of encryption systems such as SSL and IPSec that are conventionally used to secure connections over wired networks. Rather, it brings WiFi security to the level of security inherent in wired Ethernet. Thus, WiFi using WEP is insecure only because of the way it is marketed: users see it as a catch-all encryption system, rather than a replacement for the (fairly weak) security inherent to wired Ethernet's physical-access requirement.

      Beyond that, even if you DID jack in to an ethernet in a school system, you SHOULD NOT be able to access private information like grades and student records. The schools I've subbed at (unemployed programmer) have been pretty lax about securing their workstations but their GRADES etc... are secured on Novell servers.

They said the data was accessible to unauthorized users inside the network, too. And they fixed it by turning off the AP?

      I'm not familiar with the laws, but which part is the felony exactly? How can "just" getting the IP address constitute a felony? We don't even know whether the newspaper had to crack encryption to get into this network. Maybe the access point was being run wide open, as another poster suggested.

      Certainly, if they had to break in, then it's a felony; on the other hand, if the school ran the access point wide open, then there's more of a gray area.

      I have a particular interest in this. You see, I recently got in trouble with H*neywell for using their WiFi without permission. I do consulting work for a small company, and there's a H*neywell office just down the hall from where I work. Someone at that office installed a WiFi access point, apparently contrary to company policy. That access point stayed up for many months, then recently came down, and I never thought anything of it. The access point was being run entirely without security of any kind -- no WEP, no password, nothing.

      I was only using this to surf the web and download some software updates/patches to my iBook. I didn't go out looking for this access point, but my iBook is configured to find the nearest access point as soon as it wakes up from sleep (or boots up).

      Then about a week after the access point went down, I got a call from my consulting firm. It seems that H*neywell had somehow traced my use of their WiFi access point, and wanted to do something about it. I almost lost my job, but ultimately, a deal was struck whereby I surrendered my laptop to have the hard disk imaged; the laptop was returned to me less than 2 days later, fully intact.

      The official story I got was that H*neywell hired an outside firm to check their network security, and they identified the WiFi access point as a security hole; the employee who set it up was fired. Then the security firm traced all who had used the access point, and found my "digital fingerprint."

      The unofficial story I got from some other folks in-the-know is that I had posted about my discovery in my LiveJournal, and someone did a Google search and found the entry. Apparently, I forgot to make this a non-public entry. So that's how I was really found out. (That entry has been made friends-only now.) I'm still not 100% sure how Google indexed my journal, since I have my prefs set up to prevent indexing, but not all spiders respect that.

      I know H*neywell is a defense contractor, so I had assumed, when I discovered the access point, that it must be some sort of public access point for the convenience of vendors, put in a DMZ on their network. Surely, I thought, they wouldn't be dumb enough to put a wide-open WiFi access point behind their firewall! As it turns out, the access point was behind their firewall, and I could have accessed a whole bunch of material I wasn't supposed to. Scary thought.

      I think the real reason I got in trouble was that I embarrassed H*neywell. They could have conceivably taken legal action against me personally, but that would have created a weird situation for them, since it would expose them to government scrutiny. And they might lose some favorable government contracts if that happened. Moral of the story: Always check to see what you're connecting to. That hot-spot might not be safe to connect to after all!

    You bring up an interesting point, so I actually called my attorney and asked him about the points you bring up.

    Yes, just getting an IP address is a felony. FCC law says that robbing someone electronically of services or interfering with electronic transmission IS a felony.

    Well, actually, my attorney says no it isn't in my case... Because of the following argument:
    1. H*neywell is a corporate entity with known expertise in electronic communication.
    2. H*neywell is on "constructive notice" that they must secure their resources or face the possibility of people "openly and notoriously" using their resources (in this case, wireless network access).
    3. H*neywell remains silent as I and others connect to and use their wireless access point, even though they have the capability to monitor such access, and the ability to lock the electronic "gate" that bars access to this resource. (Locking the gate in this case is equivalent to putting some kind of password protection on the access point.)
    4. H*neywell has, in effect, waived their rights by not voicing objections and putting me and others on notice, and by not securing their resources.


    It was [the newspaper's] intention to access the network and they knowingly downloaded files that were sensitive in nature.

    Agreed. Intent makes the difference. Confidential information was accessed and stolen, as well.

    If you knowingly leave your door unlocked and I willingly open it and walk in, have I committed criminal trespass? According to the law I have... it's called "breaking and entering."

    Yes, that's true. I asked my attorney about this, and I learned a few things. First, the "breaking" part of breaking and entering happens when you break the plane of the door frame; the door could be completely wide open, and you're still breaking the law by walking through.

    Second, the "breaking and entering" analogy doesn't apply. The laws governing real estate and the laws governing electronic communication are a bit different. My attorney said that a closer real estate analogy to the situation we're discussing would be the following: You own 100 acres of land, and I go and squat on one corner of your property. There are no signs up saying "Do Not Trespass." You see me squatting on one acre of your property but don't do anything for a period of time (months, years). After a time has passed, your silence effectively means that you've waived your rights with respect to the piece of property that I'm squatting on, because I'm "openly and notoriously" utilizing that land. On the other hand, if you take immediate action to notify me, you've asserted your rights, and any further incident where I trespass at that point is a separate crime.

    Now, in the case of my dealings with H*neywell, if they put me on notice at any time, and I continued to access their network, then every separate instance where I connected to their network would be a specific felony. But since I was not notified until well after the fact, and because they took no measures to secure the electronic "gate" to their network, H*neywell is clearly at fault in this case.

    If I'd taken any data off their internal network, then they'd still be able to nail me for that. (And I would fully expect them to do so!)

    In the case of the newspaper accessing the school's network, confidential data was stolen. If the wireless access point was secured in any fashion, then merely breaking that security to gain access would be a crime, yes. But if no measures were taken to secure the access point, then merely obtaining an IP address by connecting to the access point wouldn't be a crime.
