Simply send a 3d printer to the victim with the designs for a ladder - guaranteed to break when the victim reaches the top. All you have to do is wait for them to change a lightbulb, allowing you several months..to a year, to come up with some kind of alibi.
Admittedly this was going to be remote
scrabble by 3d printers, but I though that was a bit boring. Also remote rock-scissors-paper, printing out hands making the appropriate gesture to the other person's 3d printer, but that was a bit tame as well.
It's one of those days....
Roald Dahl's vaguely similar invention.

You'd have to adopt some form of naming convention with
your model files, for practical purposes it would be
important to distinguish
ladder_design.3dp
from
ladder_design_MURDER.3dp. |
|
|
Erm, the first bit is ok, but towards the end it does tend to give the game away. |
|
|
Or, given metal printing an earwax removal device that just happens bear a startling resemblance to a M1911 45ACP... |

Remember: don't click on executables received over email; don't send money to Nigeria as a deposit in hopes of receiving more in return; and never use a 3D printed object in any safety critical application. |

|
Has the concept of physical hacking using 3d printing and other configurable manufacturing methods made it into sci-fi literature yet? |
|
|
A while back I was thinking about some methods for automatic manufacturing system, and it occured to me that if it was made available to build arbitrary designs from the public it would be wise to include limitations on designs so that they could not have power sources installed at the autmated manufacturing facility. Otherwise someone could program the manufacturing line to build a remote controlled robot that activates after the last construction step and jumps off the production line. It would then be free to move about the factory, spying on other customer designs, damaging equipment, etc. If that ever happened, "cleaning" the factory to be sure that there were no intruders left might be a little bit like trying to clean viruses and malware from a computer. |
|
|
This idea is a much simpler incarnation of physical hacking, using close to todays technology. (Is there a common personal 3D printer that could print a ladder tall enough to be deadly?) Like many good hacks, this takes advantage of social engineering to have a human perform the final step of turning a benign printed object into device of destruction. Well, actually I think this particular hack (building a ladder) is a bit weak, but the concept is interesting. [+] |
|
|
The concept of stealing time on automated
manufacturing equipment is found widely in SF, as is
the concept of making such machinery attack people. |
|
|
//automated manufacturing equipment is found widely in SF, |
|
|
from memory, the only one I can think if of is Jim Digriz, diverting a food packing/labelling conveyor. |
|
|
//don't click on executables |
|
|
With the emphasis on "execute". |
|
|
// The concept of stealing time on automated manufacturing equipment is found widely in SF // |
|
|
But what about the concept of buying time on the equipment and using it to build a device that will in some way compromise the manufacturing facility. Or convincing the owners to build something for themselves that turns out to be a trojan horse. These might be interesting attacks if the physical and network security was too good. Rather than exploiting a software issue like a buffer overrun error to run malicious code and install a "back door", the hacker exploits the manufacturing capablity to build a robot that might literally install a back door in the building. |

I believe it was a British minister who, commenting
on the attempts to print guns, said that once 3D
printing became commonplace we'd have people
everywhere printing of strips of Ecstasy. |
|
|
Sorry, but I'm going for "Greek horse", as it's them that made it. |
|
|
This is a sweet idea. Not so much the ladder but the idea of 3d printer as trojan horse. |
|
|
Some 3D printing methods use a dissolvable "scaffold" to support overhanging (etc) parts during manufacture. If your malicious design was designed carefully enough, the dissolving could allow parts to move; gravity providing the initial motive force, to (perhaps) launch a projectile? |
|
|
Can you offer them a 3-D printed hanky for comfort while they're waiting to expire? No use being uncivilized about it... |
|
|
//but the idea of 3d printer as trojan horse. |
|
|
Which I'm guessing wouldn't work these days as the disclaimer would mention "May contain Greeks. Packed by weapon count, not volume. Contents may settle..", but probably could be hidden in the small print somewhere... |
|
|
Greek by origin, Trojan by ownership. |
|
|
I hardly think the Trojans could be said to have //owned// it given that the Greeks retained possession of the thing for the entire time. |
|
|
//said that once 3D printing became commonplace

Ecstasy// |
|
|
If we get to the point of Star Trek replicators,
with the ability to synthesize molecules, then all
sorts of prohibitions become impossible to
enforce, unless it's done at the programming level.
Of course most of the value of such substances
goes away, since everyone can synthesize their
own for personal use. |
|
|
Until such time as that happens, the options of
what you can build are extremely limited. We're a
long way (at least 5 years, more likely a couple of
decades) from being able to create complete
machines in a single operation. The technology to
print electronics is fairly minimal, the technology
to print motors and similar is even worse, and the
ability to do multiple different materials on a
single system is completely limited by the number
of print heads. And we still aren't printing metal
components with the same strength as machined,
cast, or forged. Most "metal" printing is glued
powder, with closest to real parts being laser
sintered powder, which still does not approach
the strength or wear properties of solid metal
components, let alone the sorts of advanced alloys
that are needed for special purpose operations. |

// Greek Horse // Get over it. The statue used to conquer Troy was the Trojan Horse. That is the title for that particular object, not a descrition of the object. "Trojan Horse" is a capitalized because it is a proper noun. I doubt we know who gave it that title, but you can take it up with them in the afterlife if you don't like it. If you want to talk semantics of a description, the Trojan Horse was not a Greek horse. It was not a horse at all. It was a hollow statue of a horse with soldiers inside. |
|
|
The term Trojan horse can refer to an attack using a similar methodology. Since it's not a proper noun and doesn't actually have anything to do with the Trojans, I didn't initially capitalize "Trojan" in my annotation above, but I see in a Google search that most reference to Trojan horse attacks capitalize "Trojan" but not "horse". |
|
|
I wonder if they make condoms for horses. |

|
// Greek Horse // Get over it |

// If we get to the point of Star Trek replicators, with the ability to synthesize molecules // |
|

Replicators synthesise at the quantum atomic level. |
|
|
It depends whether your'e "replicating" from a master object, "duplicating", or "synthesising" |
|
|
Replicating from a master object is easy; it's a variation of how the transporter works. The object is scanned into a pattern buffer, then rematerialised in both the original and the new location. "Feedstock" material is fed into the system and reconfigured using the information stored in the pattern buffer. |
|
|
Duplication involves reproducing an object from a stored pattern; extensive use of compression algorithms and averaging ensure that the stored pattern isn't unmanagebly large. But this leads to single-bit errors, which mean that it's impossible to reproduce a living organism from a stored pattern. The process is, however, perfectly useable for P.E. teachers. |
|
|
Synthesising an object which has not previously existed is the most diffcult of the lot. We won't bore you with the details. |
|
|
It's all in the Star Trek Technical Manual if you care to look, although that only covers Federation technology. |
|
|
Amazing what a 1970s stage props department is able to manufacture, isn't it? |
|
|
"It was only as Michael stepped off the windowsill
that he wondered if he had mis-entered the scale
when 3D-printing his hang-glider." |
|
|
//Would that be the 1971 bumper christmas edition |
|
|
That's the one with the foreword by Abdul Alhazred? Always felt there was something fishy about that one. |
|
|
High irony potential: in the time between sending
the object & the time it does its job, you might
reconcile with the victim. Or the object might get
sold at a yard sale, and wend its way back to you... |
|
|
I have made many "ladder" art works.... so I naturally
approve. + |
|
|
3D printing, the process, appears to have a
potentially dangerous side-effect. So, perhaps that
effect could be enhanced by someone wanting to do
harm to another. See link. |
|
|
From [vernon]'s link: "The emission rates were
similar to those measured in previous studies of
several other devices and indoor activities, including
cooking on a gas or electric stove, burning scented
candles, operating laser printers, or even burning a
cigarette" |
|
|
In other words, it's all fine really. |

A design falsely labelled dog_whistle.3dp, which attracts tigers instead. |

Dog whistles don't work anyway. Mine just chewed

|
// Or convincing the owners to build something for

|
|
This is the manifest premise of Shirow Masamune's manga
'Ghost In the Shell', and to a lesser extent that of the anime
feature film. |
|
|
And about two seconds after 3d printers hit consumer level pricing, the things will default to automatically connect to the Internet. |
|
|
Thus adding another trope to the sci-fi "What happened to that alien race that isn't here anymore ?" |
|
|
Reminds me of Charles Stross "Rule 34". |
|
|
//Reminds me of Charles Stross "Rule 34". |
|
|
Simply, having just read Rule 34, I have say that
Strossy beat me to it...oh well...holds hands up. |
|
|
Or, yet another example of whoever it is with the
asynchronous wormhole going back in time to steal
my ideas before I've had them..dammit. |
|
|
// Replicators synthesise at the quantum atomic level.// |
|
|
Except that if you read the books, it's clearly indicated that
TOS replicators require large CHON feedstocks, which puts a
lie to that statement. |
|
|
Possibly by the next gen (at which time the writers would
have actually heard the word quantum), the technology
improved. |
|
|
I thought this was going to be for some kind of
crossbow or something that shot it's arrow once it
was done. Clever. [+] |
|
|
People print firearms, this would be the easy way to
do it. Have the 3d printed gun designed shoot
backwards. Rather than a bullet going out the front,
it locks in place and the recoil propels the bolt
rearwards as a projectile. |
|
|
Not quite baked but I dropped a 2D printer out the 4th floor
window and maimed an enemy once. |
|
|
Were they your enemy beforehand, or only afterwards? |
|
|
Maybe that's what crashed the Air Malaysia plane? |
|
|
Oh blimey, had a J. R. Hartley moment and found me
earliest short story. I'd sent it to Jupiter Press 01/11/2009
(declined). The story includes use of collecting random
human DNA to fox the CSI .... |
|
|
I looked up Stross's Rule 34 publication date, it's 5 July 2011. |
|
|
So, I could be wrong, but I might have had the idea first.... |
|
|
[AusCan531] Hope it was only shrapnel. 15m 'n' all. Unless
they were on the balcony of the 3rd floor. |
|
|
//Not quite baked but I dropped a 2D printer out the 4th floor window// - I'd have been more impressed if you'd dropped a 4D printer out of the 2nd floor window |
|
|
A suitably powerful laser engraver could do quite a lot of damage if the head could be rotated off the vertical axis. However, even with an industrial unit, the "cheesewire" slicing scene from Resident Evil <link> would probably not be realistic. |
|
|
An interesting question is whether you bore a hole through
someone with a sufficiently powerful laser, without actually
killing them. I suspect that a 1mm perforation to the lungs,
liver, intestines and many other vital organs would not be
fatal, especially since any blood vessels would be cauterized.
You could probably do it through the brain, unless you were
really unlucky. |
|
|
//I'd have been more impressed if you'd dropped a 4D
printer out of the 2nd floor window |
|
|
If I drop two 2D printers at the same time, do I get the same
result as dropping one 4D printer? |
|
|
// I suspect that a 1mm perforation to the lungs, liver, intestines and many other vital organs would not be fatal, // |
|
|
We could try it with a 1mm sterile steel rod, and the Intercalary ... he seems to have an unhealthy fascination with body piercings. |
|
|
Do you think it needs to be sharpened ? That's a lot of extra trouble ... |
|
|
I'll not have a finger laid on the Intercalary. He's practically a
brother. Well, technically he is a brother of course but then
so is Sturton. |
|
|
JR Hartley moment...forgot to put up a link to the story. It's
mostly wall to wall terrorism, but very eco-friendly
terrorism. See Link. |
|
|
// very eco-friendly terrorism. // |
|
|
"It's not easy being Green ..." |
|
|
You won't be so keen to admit that the next time he asks you to put up bail ... |
|
|
On such occasions I like to point out that Sturton's genome is
only marginally more similar to mine than it is to, say, a
pangolin's. |
|
