Stealing Data? A Sniffer Shows it's Easy

museumpeace writes "Though its not exactly a How-To of cracking into financial institutions, a few intriguing details are mentioned in a New York Times article "the Sniffer vs the Cybercrooks" (it's worth the cookie). From the article: ""Tell me the things you most want to keep secret," Mr. Seiden challenged a top executive at the bank a few years back.....A week later, Mr. Seiden again sat in this man's office in Manhattan, in possession of both supposedly guarded secrets....""

  1. Good thing...but far from perfect? by deathgeneral · · Score: 5, Interesting

    I think that it's good that we see companies more involved and interested in tightening up their security. Most companies just buy expensive firewalls and other systems to protect their data, but ignore other obvious threats like someone just walking into their offices and sitting down at a unused workstation and browsing around the companies network. Security is multi-layered and a continuous process, that means even if they went through a security audit and everything was ok, they shouldn't stop to improve their security,..there's always a fast-paced race between those who protect and those who will try to pass that protection. Hope this story gives other companies which don't care about security a real reason to make an audit in the very near future.

      I used to work for a school district as an IT guy. The ignorant trolls in the personnel department demanded their own locks on the doors (my master wouldn't work) and all sorts of other "special" security.

      Of course when I went to work on their machines, they would have their passwords on post-it notes on the keyboard.

      On more than one occasion, somebody would yell "hey Cindy, I need to use the blah blah system; what's the password". Cindy would yell it back to them - during business hours with lots of extra people in the room.

      Lock your network all you want, but if you hire idiots or people who don't care, it's an easy wasy to lose.

  2. It is very easy by Anonymous Coward · · Score: 5, Interesting

    During my career, I have worked as a tech break/fix. I have worked for a university, federal govt, and private sector.

    Due to the nature of the job it is difficult to get passes or keys to move around immediately, especially into secure areas. So you put on your charm and off you go.

    It is very easy to take things. Just look like you know what you are doing and where you are going.

    Be presentable and nice, be friendly with the receptionists/secretaries/admin, and you can go anywhere.

    I have been let into computer rooms that are supposedly secure, I have been assisted by security guards in loading computer gear into my car, I have had secretaries hold doors on elevators so I could get stuff in. I'm talking thousands upon thousands of $$$ worth of stuff. All of them took my word for it, never questioning or phoning to find out. I have never had to show ID.

    I have actually had one employee of a major oil corporation watch me follow him in through the doors, ask me, "Where are you going? Who are you?"
    This was going into their engineering areas, from which I'm sure numerous other oil companies would love to see the data.

    I replied that I am a computer tech and visting XXXXXXX. "Who? Are they on this floor?" "Yeah, they are, around the corner." (I really only had an office number ;-) "Oh, ok. You look honest." He actually told me I looked honest, so it was ok! From there I found the office I wanted, no one was there. I was to swap out a couple of hard disks, so I did. Many people poked their head in, joking along the way, "Hey! You don't look like XXXXXXXX! Unless he's shrunk! hahaha!" One even to see "what does a hard disk look like?" No one questioned me from there.

    Many, too many to count, I have just knocked on the door and asked for Mr. S.A.S. "Oh, I'm here to take a look at his computer, he said it wasn't working. Can I see it?" Then they lead me to the office, in which Mr. S.A.S. isn't there. "Well, I'll just start and he'll come back and I'll let him know. Thanks." Then they leave.

    It doesn't matter how secure it is, like the article points out, being sociable gets you lots of open doors.

    Crazy part is that I pride myself on this "talent." It's much simpler to talk your way through than to have to run all over getting ok's and escorts into areas.

    I'd consider security as being essentially split into the following layers:


    • Stopping intruders getting onto the network in the first place (firewall, limited use of public IP addresses, etc)
    • Stopping users on the network from accessing machines they shouldn't (ie: strong user authentication, eg: Kerberos)
    • Stopping machines on the network from accessing other machines they shouldn't (ie: strong host authentication)
    • Stopping sniffers and vulnerability scanners by using encrypted network traffic (eg: IPSec, Sun SKIP, or something similar)
    • Removing code that has known exploits, to prevent the bypassing of any of the above
    • Using Active NIDS to detect attempts to break the security


    In practice, almost no organization is going to install all of the above. Even the US Government, which is not short of ready cash, is getting far poorer grades on their network security audits than they should.


    However, if you define the "target" or "ideal" security schema, then you have something you can compare against. IMHO, the above description is the "ideal", in that it is unlikely that anyone would be able to break in using technological methods.


    The remaining problem - social engineering - is not something you can program against. The description I outlined, if implemented in full, would provide enough checks and counter-checks to require someone using social engineering to get past several people, which raises the bar a little but does not make it hard enough.


    ("Hard Enough" is defined here as making it an impractical method for typical IT situations.)

  5. Customer service by imgumbydammit · · Score: 3, Interesting

    One of the main reasons that approaches like social engineering work is because of the overwhelming emphasis a lot of companies put on "customer service".
    I worked for several years in corporate security (good money/awful job), and it was the cardinal sin to piss someone off. On one occasion, a white guy showed up on a weekend with a pass card with a Vietnamese woman's name on it that wasn't cleared for access to the floor he wanted to get onto, which was the executive floor of a bank nonetheless.
    The ten minutes it took to verify this guy's identity were the cause of a major spat between him (he turned out to be a VP of some sort) and my employer (the building management) that took days to blow over.
    Some of my colleagues would simply give in if someone was pushy enough. No one wants to be the person who said "No" to the wrong person, no matter what the circumstances.
