Hacking Wireless Security Systems

    How hard is it to "hack" a wireless security system? For example, if I
    installed one of the wireless key fobs or had a wireless handheld
    keypads, would it be difficult for a sophisticated burglar to simply
    disarm the security system?

    What security mechanisms, if any, are in place to protect against this
    type of attack. Are their security codes you need to put into the key
    fob/handheld. Do these keys rotate or are they static. How many
    possible codes are there (to prevent an attacker from trying all
    codes).

    I expect buglars with advanced techniques to do this is unlikely. I'm
    just curious from an academic point of view.

    I'm not sure if this is the appropriate venue to discuss the topic,
    but, if a burglar would attempt to do this. What would they need? Some
    sort of RF sniffer? Or just a programmable fob?

    Thanks in advance, I know this issue may be controversial considering
    all the other postings I've on wireless vs hard-wired.

    A perp couldn't use just any wireless keypad of the same brand as your
    system. They have to be "enrolled" to your particular panel. If a perp
    were to obtain the wireless keypad for *your* system it would take him
    awhile to discover the four digit code you use to disarm. Some panels
    employ an anti-hacking feature that your installer can enable (three or four
    wrong code entries and the system "locks" for a period of time programmed by
    your installer *and* transmits a code to the Central Station). He could
    also inadvertently enter a "duress" code with some rather embarassing
    results (for him). A keyfob with a single button "off" wouldn't present any
    difficulty (which is why I normally recommend people use fobs to *arm* the
    system, but not *disarm* it). If you *do* manage to lose a wireless keypad
    or fob, though, make sure you contact your security company so they can
    disable it (this can be accomplished by downloading the information to your
    system without having a service man actually visit).
    On a system that employs a four digit access code, there are 10,000
    combinations. That number goes down with the number of different codes you
    have programmed in.

    It's a question I frequently get asked.

    An RF sniffer won't help him. A programmable fob or wireless keypad would
    have to be enrolled in the system to work with it. You can only do this
    through installer level programming or by downloading the fob's/keypad's
    unique serial number to the panel. Both these methods are beyond the
    capability of any burglar.


    No problem...

    the best way to find all the info you want is to go to all the main
    producers of wireless and check out there sites. The combinations are huge
    and doubtful a burglar would have the equipment or patience for a simple
    home invasion.

    Don't know what movies you've been watching... The only one that mentioned
    anything about "replay" I enjoyed recently was "The Fifth Element"... I
    mean we're talking the same level of "expertise" as the ex-KGB guys in that
    Cindy Crawford movie. That's way out of league of the "perp on the street".
    Even if he did manage to "hack" the serial number of the keypad (highly
    unlikely), he'd have to use an *identical keypad* and the arming code to
    disarm the system... If you ask me, it's simpler for him to kick in the
    front door, run to the master bedroom, grab what loot he can that's easily
    transportable, and get the heck out... Like three to five minutes...

    Any system can be compromised. Even systems installed to DCID 6/9
    specs, which are used to protect top secret level classified
    materials, aren't absolutely secure. It's interesting to note that
    such specs prohibit wireless technology unless in is absolutely
    necessary and the wireless technology is "impervious to jamming,
    manipulation, and spoofing."

    As a general rule hardwired systems are more secure, but for a
    residential application, the likelihood that someone could or would
    "hack" a wireless system is so remote that it shouldn't be a concern.

    Oh yeah, but I made up for it with my other post... jeez...I wouldn't want
    anyone to think I can answer in one sentence when 100 will do it a bit
    better....:))))

    Has anyone seen Greg Morris on TV in the last 20 years? Might be a good
    reason why.....

    I see you are adding my name instead of the default reply. You must
    love me. I feel so special. You are a scumbag Robert L. Bass.

    Just what we would expect from a "lay minister". He say's he does not
    hate me, his actions prove otherwise.

  13. Great the way you appear on command, Basshole.
     
  14. He only does the lay minister to get close to teen boys.
