This discussion has brought 2 points to my attention. Firstly, the port
scanning being classified as an offence/attack. This *must* have some kind
of limitations set on it. For example, my ISP conducts routine scans on
their customers machines to ensure people aren't running public servers for
eg., which would be in breach of the T&C of the service. Under this bill,
because my ISP is probing my machine, does that make their actions illegal?
I doubt I'd have any luck trying to bring a prosecution against them under
this law. This would therefore set a precedent, which any good lawyer will
be able to manipulate. This happens with any new and "radical" law - test
cases come before the courts, and the results of these have a huge bearing
on the interpretation of the statutes. However, ignoring that for the
moment, consider an organisation like ORBS. Are they now in contravention of
this law by scanning random machines outside of their control for a specific
(excuse the loose phrase) "exploit", ie: open relay?

But onto the more worrying part of this. From the message below:

To qualify, an intrusion or attack would
have to cause one
of the following:
<snip>
2) physical injury to any person;
3) a threat to public health or safety

This is a problem. A *BIG* problem. In my country we have 2 legal "tests",
to assist in determining innocense or guilt. Firstly, the "Reasonable Man"
test. This states that under the circumstances in question, what would any
normal, reasonable human being do. For example, I try to telnet to my own
server, and mistype the IP. I end up connecting to somebody else's server,
and r00t it by accident. The "Reasonable Man" test says that I should
disconnect from the system and possibly inform the system owner. Secondly,
the "Egg Shell Skull" rule. This rule states that you are responsible for
the end result of your actions regardless of whether they were intended or
not. For example: "egg shell skull" is a medical condition where the
sufferer has an extremely thin skull. If I was to hit a *normal* person
round the head with an empty plastic bag, they may fall down but not sustain
any injury. However, if I hit a person with an egg shell skull in the same
way, I would kill them. In court, you would be tried on the basis of
murder/manslaughter - it is irrelevant that you never intended to kill this
person, and you had no way of knowing what the outcome of your actions were.

Excuse the long description, however there is a reason. I work for a company
that provides support to   a company that sells "items" to the public (sorry
for the obfuscation). These items will almost certainly cause death or
serious injury if the stringent safety procedures are not met. Because we
support the networks of this company, we have direct access from our offices
via WAN links to the company in question. This means we can access the
servers that are responsible for the manufacturing & safety processes.

Now, imagine if an attacker tried to penetrate our network. There is nothing
immediately obvious to warn an attacker of the above information. Assume
they got past the first firewall and no further. Any good lawyer could
present an argument that showed the attacker had broken rules 2 and 3 above.
Using the reasonable man test, the attacker is guilty (a reasonable human
would not try to hack a private system). Also, by penetrating the network,
the attacker has no way of knowing what downstream effects they have caused
(say the attacker changed the system clock on a server to mask his
presence). It would be fairly easy to show that changing the time affected
time based transaction systems, which in turn affected machines controlling
safety procedures, which in turn means that the safety compliance status
cannot be verified, thus causing a threat to public health & safety. Using
the egg shell skull rule, this attacker is in serious danger of being
prosecuted for manslaughter (you are responsible for the end result,
regardless of your intentions), and they've not even touched anything.

Now you may consider this a little far fetched or a stretch, and admittedly
the last manslaughter part may be. However, look at Mitnick, SK8, and the
multitude of others in their position. All treated with rules that bend more
than my flexible American Express friend. Plenty of people look at
contemporary legal decisions and quite rightly call them insane, illogical
or bizzare. But these decisions stand nonetheless. Lawyer: "But Mr hacker,
can you prove beyond all reasonable doubt that your accessing of this
network did not in any way affect any other systems". Hacker: "No, I can't".
Judge: "Here, have 25 to life".....

Just my opinion.
