i took this instructable down for a few months because my sign hacking incident made it into the local paper and i had to lay low for a while, so i guess you have a good example of the riskiness of pulling this off.

if you are able to pull this off, i am entirely responsible. feel free to include my name in your court case.
but honestly, I'm just sharing this for scientific purposes not vandalism.

i was inspired to do this because of the i-hacked article but this turned out to be totally different to the device i encountered, so after getting it to work i felt compelled to share how i got it to work.

so, lets get started shall we!

if you are going to attempt this you are going to want some tools capable of "conquering" a padlock.
might i recommend a crowbar. but pack lightly as some evasive running may be in order if someone should come to investigate the scene.

Step 1:

Locating a sign

these signs aren't hard to locate, just search for areas like traffic zones or roadworks areas. once found it would be best to park some distance form the scene to keep your getaway vehicle less obvious.

Oh wow. This is amazing. I wouldn't do it personally due to the overall risk, but still amazing.

You are badass! I probably wouldn't rip out the transmitter, and I was hoping for a more thourough guide.
I saw this done as a boycott effort against BP. I don't want to go to jail or have a felony record. So I probably won't try it.

Use a lock gun to break the lock. They are around $30-$40.
ive found somewhere else that the password is DOTS as a default, and if it's not, Hold Control and Shift and while holding, enter DIPY. this should work.

That is simply AWSOME 5 stars+faved what is the limit of characters you can put ?
7 characters on each row. and there are 3 rows... so 21 in all or maybe it scales down the letters when you add more than that.
cool thanks

hmm... Something really funny to do on one of these is to advertise porn or something on a busy highway or near a school that would be freaking hilarious.

I saw this on the news this morning (in orlando). the sign said "caution zombies, run!" Obviously a copycat of the article on i-hacked.

Flagged as inappropriate as it encourages vandalism and other illegal activities.
hcold mrmath6 years ago
Vandalism implies destruction of property. Err, wrong. Illegal activities? "haxoring" huh? I'd get that pole check as soon as possible, it seems to have ruptured your sense of humour along with your lower intestines.
mrmath hcold6 years ago
I quote from step two: "once in the computery space you will see a small black/grey box with loads of antenna cable coming out of it, as a precaution; rip it out or with it with your crowbar. not sure what it dose but transmitting anything cant be a good thing. you have now broken in entry as well as committed vandalism, don't tell your mother." (many, many instances where SIC would be appropriate in that quote) Ripping out the transmitter is vandalism, and illegal. Messing with the signs in general would be illegal, too, I would assume. I don't, however, know that for a fact, so I'm not going to say it is.

Its the internet. Get over it. Youre not the one doing this, so why care.
hcold mrmath6 years ago
I am chatised. However, I couldn't care less.
JakeTobak hcold6 years ago
You not caring doesn't change the definition of vandalism. This is vandalism, you were wrong, don't be a jerk about it.
hcold JakeTobak6 years ago
I thought saying "I am chatised" qualified as conceding the point. And yeah, being a jerk on the Internet is kind of a prerequisite.
JakeTobak hcold6 years ago
Ah, my bad, didn't know what you meant. It's not a word I see a lot, so when one letter is missing it throws me off :P
wupme mrmath6 years ago
I gotta say, that also was one of the first things that came to my mind. Breaking that "Reciever" or whatever it is, or just removing it is vandalism (if you keept it.. you also stole it, thats probably even worse). Hacking that sign and opening the lock is also illegal. Could be different it wasn't locked at all, but don't hold me for that.

AUSTIN (KXAN) - Austin drivers making their morning commute were in for a surprise when two road signs on a busy stretch of road were taken over by hackers. The signs near the intersection of Lamar and Martin Luther King boulevards usually warn drivers about upcoming construction, but Monday morning they warned of "zombies ahead."
shooby6 years ago
Vandalism? Nothing is damaged, in fact many of these messages encourage slow driving!
Step 2; "rip it out or with it with your crowbar." sounds awfully vandalizing to me :D
Ok ok, I didn't read the whole thing! : )
hahahahaha fair enough
wupme shooby6 years ago
Or may cause an accident.... both is possible. I don't think either will happen ;-)
