    One often hears penetration testing described as ethical hacking.  If that
    is so and what we are practicing here is ethical, then we must act
    ethically.  To my mind, that means owning up to one's mistakes.  If we do
    not, then we are little different from the other kind of hackers from which
    we are trying to protect our clients.  Failing to act ethically in an
    instance such as this lowers the credibility and value of our profession.
    
    As another response to this thread indicated, an Errors and Omissions
    insurance policy is very important because of occurances such as these.  Not
    only will you be better protected but so will your actual client.  The
    client that contracted you to test his system may be at legal risk for your
    actions against the unintended target.  If you fail to come clean and you
    are found out, then the victim may have recourse against both you and your
    client, and both your client and the victim may have recourse against you,
    your partners and associates.
    
    My advice is to first get legal representation and work with your attorney
    to contact the parties involved.  Be prepared to cover any damage that may
    have resulted.  Acquire the appropriate insurance for future engagements and
    be much, much more careful.

    I agree with this person, if you volunteer information to this company, you
    could be hit with illegally scanning their systems (because you do not have
    consent to do so).  You could very well land in jail with the local
    authorities possessing your systems for a few years.  Even if you win your
    systems back, they will be so old and outdated that they will be useless.
    
    Delete your logs and redo what you were hired to do in the first place.
    
    Also, on a side note, didn't the letter stating that you were allowed to do
    this scan have the valid IP addresses you were allowed to scan?  If it
    didn't, you need to have your legal department reconstruct the letter to
    start incorporating this valuable piece of information.
    
    I'll jump off of my soapbox now!

    Let's just say, for theoretical purposes, that you
    were contracted to perform a penetration test on a
    company.  After receiving the IP range from the
    company, you begin the test.  You're well into the
    test and find several vulnerable servers, which you
    promptly own six ways from Sunday.  Then a co-worker
    wanders into your company's lab and looks over your
    shoulder and advises you that the hosts that you're
    owning are a single digit in the subnet off from the
    hosts you're supposed to be attacking.
    
    Example, I've owned 192.168.10.35, when in actuality I
    was supposed to be owning 192.168.11.35.
    
    How do you handle this situation?
    
    My vote is to contact the owners of the site, advise
    them honestly of the mistake, offer assistance (free
    of charge of course) in correcting the security
    problem you used to own them, and walk away a bit the
    wiser.
    
    Anyone else have any better advice?
